SAFETY SECTION

This Safety Section should be read before commencing any work on the equipment.

Health and safety

The information in the Safety Section of the product documentation is intended to
ensure that products are properly installed and handled in order to maintain them
in a safe condition. It is assumed that everyone who will be associated with the
equipment will be familiar with the contents of the Safety Section.
Explanation of symbols and labels
The meaning of symbols and labels which may be used on the equipment or in the
product documentation, is given below.

Caution: refer to product documentation Caution: risk of electric shock

Protective/safety *earth terminal

Functional *earth terminal.

Note: this symbol may also be used for a protective/
safety earth terminal if that terminal is part of a
terminal block or sub-assembly eg. power supply.

*Note: The term earth used throughout the product documentation is the direct
equivalent of the North American term ground.

Installing, Commissioning and Servicing

Equipment connections
Personnel undertaking installation, commissioning or servicing work on this
equipment should be aware of the correct working procedures to ensure safety.
The product documentation should be consulted before installing, commissioning or
servicing the equipment.
Terminals exposed during installation, commissioning and maintenance may
present a hazardous voltage unless the equipment is electrically isolated.
If there is unlocked access to the rear of the equipment, care should be taken by all
personnel to avoid electric shock or energy hazards.
Voltage and current connections should be made using insulated crimp
terminations to ensure that terminal block insulation requirements are maintained
for safety. To ensure that wires are correctly terminated, the correct crimp terminal
and tool for the wire size should be used.
SERVICE MANUAL R8605B
M301, M302 Volume 2
Contents

Before energising the equipment it must be earthed using the protective earth
terminal, or the appropriate termination of the supply plug in the case of plug
connected equipment. Omitting or disconnecting the equipment earth may cause a
safety hazard.
The recommended minimum earth wire size is 2.5 mm2, unless otherwise stated in
the technical data section of the product documentation.
Before energising the equipment, the following should be checked:
Voltage rating and polarity;
CT circuit rating and integrity of connections;
Protective fuse rating;
Integrity of earth connection (where applicable)

Equipment operating conditions

The equipment should be operated within the specified electrical and
environmental limits.
Current transformer circuits
Do not open the secondary circuit of a live CT since the high voltage produced
may be lethal to personnel and could damage insulation.
External resistors
Where external resistors are fitted to relays, these may present a risk of electric
shock or burns, if touched.
Battery replacement
Where internal batteries are fitted they should be replaced with the recommended
type and be installed with the correct polarity, to avoid possible damage to the
equipment.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At the
end of each part of the test, the voltage should be gradually reduced to zero, to
discharge capacitors, before the test leads are disconnected.
Insertion of modules and pcb cards
These must not be inserted into or withdrawn from equipment whilst it is energised,
since this may result in damage.
Fibre optic communication
Where fibre optic communication devices are fitted, these should not be viewed
directly. Optical power meters should be used to determine the operation or signal
level of the device.
SERVICE MANUAL R8605B
M301, M302 Volume 2
Contents

Older Products
Electrical adjustments
Equipments which require direct physical adjustments to their operating mechanism
to change current or voltage settings, should have the electrical power removed
before making the change, to avoid any risk of electric shock.
Mechanical adjustments
The electrical power to the relay contacts should be removed before checking any
mechanical settings, to avoid any risk of electric shock.
Draw out case relays
Removal of the cover on equipment incorporating electromechanical operating
elements, may expose hazardous live parts such as relay contacts.
Insertion and withdrawal of extender cards
When using an extender card, this should not be inserted or withdrawn from the
equipment whilst it is energised. This is to avoid possible shock or damage
hazards. Hazardous live voltages may be accessible on the extender card.
Insertion and withdrawal of heavy current test plugs
When using a heavy current test plug, CT shorting links must be in place before
insertion or removal, to avoid potentially lethal voltages.

Decommissioning and Disposal

Decommissioning: The auxiliary supply circuit in the relay may include

capacitors across the supply or to earth. To avoid electric
shock or energy hazards, after completely isolating the
supplies to the relay (both poles of any dc supply), the
capacitors should be safely discharged via the external
terminals prior to decommissioning.
Disposal: It is recommended that incineration and disposal to water
courses is avoided. The product should be disposed of in a
safe manner. Any products containing batteries should have
them removed before disposal, taking precautions to avoid
short circuits. Particular regulations within the country of
operation, may apply to the disposal of lithium batteries.

Section 2. INTRODUCTION TO MICOM

MiCOM is the new range of substation protection and control products from
ALSTOM T&D Protection & Control. Central to the concept of MiCOM is
communication; communication between the different products in the range and
between the MiCOM products and substation control and SCADA systems. This
enables MiCOM to provide a comprehensive range of integrated protection and
control equipment which is capable of fulfilling all substation requirements.
The MiCOM range includes a wide selection of protection relays (the P series),
measurement products for accurate metering and monitoring (the M series) and
versatile communication support packages for personal computer interrogation of
the products (the S series).
All MiCOM products include facilities for recording a multitude of information on
the state and behaviour of the power system through disturbance and fault records,
but also can provide measurements of the system at regular intervals to a control
centre to enable remote monitoring and control to take place.
There are several personal computer based support software packages in the
MiCOM range which are custom designed for use with the other MiCOM
products:
• MiCOM M300 setting software is designed for local control of a single
measurement centre and provides facilities for changing product settings and
viewing measurands. This package communicates via the ModBus protocol.
• MiCOM S1 is designed for local control of a single relay and provides
facilities for operations such as changing the relay settings, programming the
protection scheme logic and extracting disturbance and fault records. This
package communicates via the Courier protocol.
• MiCOM S10 provides substation-wide communication with many MiCOM
products and is capable of extracting and displaying measurements from an
entire substation. Also MiCOM S1 can be combined with MiCOM S10 to
allow control of the relay settings for all MiCOM devices within a substation.
The range of measurement products in the MiCOM range presently includes the
following products:
M100 panel mounted energy meters
M210 system measurement centre
M300 system analysis and measurement centre
For up-to-date information on any of the products in the MiCOM range see the
latest MiCOM publications.
2.1 User interface and menu structure
The settings and functions of the M300 can be accessed from either the front panel
or rear communications port. The M302 has only communications ports and no
local user interface.
2.1.1 Menu structure and password protection
The front panel user interface is arranged in a hierarchical structure which is
designed to provide an intuitive interface eliminating the need for constant
recourse to the service manual. There are three main layers to the menu. Layer 0 of
SERVICE MANUAL R8605A

the menu allows access to the measured parameters. Layer 1 allows access to the
different setting groups. Once the appropriate setting group that requires changing
is located then access can be gained to the actual setting.
Different password access levels are allotted according to the security criteria of
individual settings.

The front panel will return to a default display if the front panel interface is inactive
for more than 15 minutes. If this happens any setting changes which have not been
confirmed will be lost and the original setting values maintained. The default
display is the layer 0 menu position last displayed by the unit.

2.2 Reading and clearing of alarm messages and fault records

The presence of one or more alarm messages will be indicated by the ALARM LED
being illuminated on the M301. (The M302 has no display so access to alarms is
via the serial communications only.) The alarm messages can be viewed by
repeated pressing of the READ key and will appear in sequential order. When all
alarms have been viewed, but not cleared, the ALARM LED will continue to be
illuminated.
Pressing the CLEAR key will clear all alarm messages.

2.3 Communication ports user interface

The Measurement Centre has two communication ports located on the rear of the
unit:
A 9 pin D-type connector which can be configured to be an RS232 ModBus port
or an IEC 870 Courier port.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 1
Page 26 of 28

A set of screw terminals for connection via twisted pair wiring and RS485
communication to a master terminal at a more distant location (up to 1000m).
This is designed for use with a permanently wired communication system covering,
for example, a whole substation, and can connect a number of units to a single
master station for monitoring and control purposes. This port can be configured as
a either a K-BUS COURIER port or RS 485 ModBus port.
2.4 Courier communication interface
Courier is the communication language developed by ALSTOM T&D Protection &
Control to allow remote interrogation of its range of protection relays and is fully
supported by the MiCOM range. Courier works on a master/slave basis where the
slave units contain information in the form of a database, and respond with
information from the database when it is requested by a master unit.
The Measurement Centre is a slave unit which is designed to be used with a
Courier master unit such as MiCOM S1, PAS&T, ACCESS or a SCADA system.
The operations and functions supported by Courier communications are as follows:
display and modification of all settings
extraction of digital status
extraction of measurements
extraction of fault records
extraction of event and alarm records
manual extraction of disturbance records
reset of alarm conditions
clearing of event records
time synchronisation
automatic extraction of event and disturbance records
2.5 ModBus communication interface
ModBus is another master/slave communication protocol which can be used for
network control. In a similar fashion to Courier, the system works by the master
device initiating all actions and the slave devices (the Measurement Centres)
responding to the master by supplying the requested data or by taking the
requested action. ModBus communication can be held over the RS232 or RS485
links provided (but not at the same time). Using the RS485 port up to 32 slave
devices can be connected together over a distance of up to 1000m.

Section 1. GENERAL CONSIDERATIONS

1.1 Receipt of M300

The M300, although generally of robust construction, requires careful treatment
prior to installation on site. Upon receipt, units should be examined immediately to
ensure no damage has been sustained in transit. If damage has been sustained
during transit a claim should be made to the transport contractor and ALSTOM
T&D Protection & Control Ltd should be promptly notified.
Units that are supplied unmounted and not intended for immediate installation
should be returned to their protective polythene bags.
1.2 Electrostatic discharge (ESD)
M300 has components that are sensitive to electrostatic discharges but the
electronic circuits are well protected by the case.
There are no setting adjustments within the unit and the M300 is not designed to
be dismantled, considerable effort being required to do so.
Touching the printed circuit boards should be avoided, since complementary metal
oxide semiconductors (CMOS) are used, which can be damaged by static
electricity discharged from the body.

Section 2. HANDLING OF ELECTRONIC EQUIPMENT

A person's normal movements can easily generate electrostatic potentials of

several thousand volts. Discharge of these voltages into semiconductor components
when handling electronic circuits can cause serious damage, which often may not
be immediately apparent but the reliability of the circuit will have been reduced.
The electronic circuits are completely safe from electrostatic discharge when
housed in the case. Do not expose them to risk of damage by withdrawing
modules unnecessarily.
Each unit incorporates the highest practicable protection for its semiconductor
components. However, if it becomes necessary to dismantle a unit, the following
precautions should be taken to preserve the high reliability and long life for which
the unit has been designed and manufactured.
1. Before dismantling a unit, ensure that you are at the same electrostatic potential
as the unit by touching the unit case earth.
2. Handle printed circuit boards by their edges. Avoid touching the electronic
components, printed circuit track or connectors.
3. Do not pass the printed circuit boards to another person without first ensuring
you are both at the same electrostatic potential. Shaking hands achieves
equipotential.
4. Place the printed circuit boards on an antistatic surface, or on a conducting
surface which is at the same potential as yourself.
5. Store or transport the printed circuit boards in a conductive bag.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 2
Page 2 of 4

If you are making measurements on the internal electronic circuitry of a unit in

service, it is preferable that you are earthed to the unit's case earth with a
conductive wrist strap. Wrist straps should have a resistance to ground between
500kΩ - 10MΩ. If a wrist strap is not available you should maintain regular
contact with the case earth to prevent a build-up of static. Instrumentation which
may be used for making measurements should be earthed to the case earth
whenever possible.
More information on safe working procedures for all electronic equipment can be
found in BS5783 and IEC 147-OF. It is strongly recommended that detailed
investigations on electronic circuitry or modification work should be carried out in
a special handling area such as described in the above-mentioned BS and IEC
documents.

Section 3. UNIT MOUNTING AND CONNECTION

Units are dispatched individually for panel (M301) or DIN rail (M302) mounting.

Section 4. UNPACKING

Care must be taken when unpacking and installing the units so that none of the
parts is damaged. Units must only be handled by skilled persons. The installation
should be clean, dry and reasonably free from dust and excessive vibration.
The site should be well lit to facilitate inspection. Prior to installation, units should
not be left in situations where they are exposed to dust or damp. This particularly
applies to instalations which are being carried out at the same time as construction
work.

Section 5. STORAGE

If units are not to be installed immediately upon receipt they should be stored in a
place free from dust and moisture in their original cartons. Where de-humidifier
bags have been included in the packing they should be retained. The action of the
de-humidifier crystals will be impaired if the bag has been exposed to ambient
conditions and may be restored by gently heating the bag for about an hour, prior
to replacing it in the carton.
Dust which collects on a carton may, on subsequent unpacking, find its way into
the unit; in damp conditions the carton and packing may become impregnated
with moisture and the de-humidifier will lose its efficiency.
Storage temperature –25ºC to +70ºC.

Section 1. INTRODUCTION

The M300 products are fully numerical in their design, implementing all functions
in software. They employ a high degree of self checking so that, for the majority of
failures that could occur within the product, all functions will cease to operate and
an error will be flagged. As a result of this, the commissioning tests do not need to
be as thorough as with products using electromechanical and discrete electronic
components. To commission the M300, it is only necessary to verify that the
hardware is functioning correctly and the application-specific software settings
have been applied to the unit.
It is also considered unnecessary to test every function of the unit if the settings
have been verified by one of the following methods:
• Extracting the settings applied to the M300 unit using appropriate setting
software (preferred method)
• Via the operator interface (M301 Measurement Centre only).
The number of tests to be performed will depend on the hardware option that has
been installed in the unit. The hardware option installed can be found from the
“Fitted Hardware” window under the “SYSTEM CONFIGURATION” heading or
directly from the seventh character in the unit’s model number. Table 1 details the
tests that need to be performed for each hardware option.
Unless previously agreed to the contrary, the customer will be responsible for the
correct selection of settings and any interwiring between units.
Blank commissioning test and setting records are provided at the end of this
chapter for completion as required.
BEFORE COMMISSIONING THE M300, REFER TO THE SAFETY AND
INSTALLATION SECTIONS OF THE MANUAL.

Section 2. PRODUCT MENU FAMILIARISATION

When commissioning an M301 for the first time, an hour should be allowed to
become familiar with the menu. Chapter 1 contains a description of the menu
structure.
Similarly, if a portable PC with appropriate software is being used to set the unit,
time should be allowed to become familiar with the associated setting software.
This software is essential for setting the M302 because it does not have an integral
user interface. For details of the operation of this software, please refer to the
associated software user manual.

Overcurrent test set.
AC voltage source (if not included in the overcurrent test set)
True rms measuring multimeter of known calibration accuracy with suitable ac and
dc voltage and current ranges
Audible continuity tester (if not included in multimeter)
Electronic timer (if not included in the overcurrent test set)
Phase angle meter
Phase rotation meter
A portable PC, with appropriate software (Essential for the M302 and testing the
communications port on M301. Also recommended for setting M301.)
Suitable DC source dependent on DC analogue input options.
3.2 Additional equipment
A printer (for printing a setting record from the portable PC).

Section 4. PRODUCT VERIFICATION TESTS

WARNING: BEFORE COMMISSIONING THE M300, THE SAFETY AND

INSTALLATION SECTIONS OF THE MANUAL SHOULD BE REFERRED TO.
The product verification tests cover all aspects of the product that need to be
checked to ensure that the unit has not been damaged prior to commissioning, is
functioning correctly and all measurements are within the stated tolerances.
The voltage transformer supply to the unit should be isolated by means of the panel
links or connecting blocks and the line current transformers should be short-
circuited and disconnected from the unit terminals .
DANGER: NEVER OPEN CIRCUIT THE SECONDARY CIRCUIT OF A
CURRENT TRANSFORMER SINCE THE HIGH VOLTAGE PRODUCED MAY
BE LETHAL AND COULD DAMAGE INSULATION.
4.1 With the unit de-energised
The following group of tests should be carried out without the auxiliary supply or
measured voltages or currents being applied to the unit.
4.1.1 PVI: Visual inspection
Carefully examine the unit to see that no damage has occurred prior to
commissioning.
Check the rating information on the rating label of the unit to ensure it is correct for
the particular installation. Regardless of whether a M301 or M302 is being
commissioned, this label is located in the centre of the unit between the terminals.
Ensure that the case earthing connection, located in the bottom corner near the
right-hand terminal block, is used to connect the unit to a local earth bar.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 3
Page 4 of 38

4.1.2 PV2: Insulation

Insulation testing is not essential but may be required by the customer.
If insulation tests are required, isolate all wiring from the earth and test the
insulation with an electronic or brushless insulation tester at a dc voltage not
exceeding 1000V. Terminals of M300 circuits of the same type should be
temporarily wired together.
The main groups of terminals on the unit are:
a) Voltage transformer circuits
b) Current transformer circuits
c) Auxiliary voltage supply
d) Status inputs
e) DC Opto-isolated inputs
f) Relay outputs
g) RS232 Communication port (COM1)
h) RS485 Communication port (COM2)
i) Analogue outputs
j) Earth tab
On completion of the insulation tests, ensure all external wiring is correctly
reconnected to the unit.
4.1.3 PV3: External wiring
Check that the external wiring is correct to the relevant connection or scheme
diagram. The connection diagram for the M300 can be found in Volume 2,
Chapter 2 of this manual.
4.2 With the unit energised
The following group of tests verify that the unit’s hardware and software are
applied and functioning correctly. They should be carried out with the auxiliary
supply applied to the unit but not the measured voltages or currents.
There are two auxiliary voltage ranges available for the M300. The operating
ranges are specified in Table 2. Without energising the unit, measure the auxiliary
supply to ensure it is within the operating range.
Auxiliary rating Operating range
24/70V 19 to 84V dc only
70/250V 56 to 275V dc or ac
Table 2 Operational range of auxiliary supply

It should be noted that the unit can withstand ac ripple of up to 12% of rated
voltage on the dc auxiliary supply.
The M300 units are protected against overloads created when batteries are
removed and the charger is left in place. However, this mode of operation is not
recommended as other units, such as protective relays, powered from the same
supply may not have this overload protection.
Energise the unit if the auxiliary supply is within the operating range.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 3
Page 5 of 38

4.2.1 PV4: Light emitting diodes (M301 only)

On power up, the top and bottom light emitting diodes (LEDs), “Out of Service”
and “Alarm” respectively, should have illuminated and stayed on. The “Out of
Service” LED is illuminated because the frequency tracking signal is not present
and the “Alarm” LED because the real time clock needs to be set. The “Out of
Service” LED will extinguish when rated AC quantities are applied to the voltage
and current inputs. The “Alarm” LED will extinguish when the real time clock is set.
The status of the other (“Set Point” and “Trip”) LEDs is stored in non-volatile memory
which remembers whether they were on or off when the auxiliary supply was last
removed from the unit. Therefore these indicators may also illuminate when the unit
is powered up. Operator intervention is required to extinguish these LEDs.
4.2.2 PV4: Set the real-time clock
The real-time clock cell is located in the SYSTEM CONFIGURATION menu.
When the real time clock is displayed, the time and date are set by pressing the
'Enter' key to enter the setting mode. The up and down arrow keys can then be
used to change the values, the left and right arrow keys allow changes to be made
to the other values of the real time clock. Once the desired values are inserted
press the Enter key to confirm settings.
4.2.3 PV4: Reset alarms
All LEDs that are illuminated should be reset before proceeding with further testing.
The “Alarm” LED should have reset when the real time clock was set.
If the “Set Point” and “Trip” LEDs are illuminated and then successfully reset (the
LED’s will extinguish), there is no testing required because the LEDs are known to
be operational.
4.2.4 PV4: Test the “Set Point” and “Trip” LEDs (M301 only)
If operation has not already been established, the “Set Point” and “Trip” LEDs can
be tested by exceeding the threshold of a set point as in the following:
Set one setpoint in a set point group to be Ιa, set the set point time delay to be 1
second, set the high level to 50% and low level to 0%.
Apply rated voltage and current to bring the unit into service.
To test “Set Point” LED operation apply 50% of rated current to Ιa, then raise to a
level above 50%, which should illuminate the set point LED. (When the current is
above 50% the set point alarm cannot be reset nor the LED extinguished).
Reduce Ιa to 40% of rated current, this will enable the set point alarm to be reset
and the LED will extinguish.
To test the operation of the “Trip” LED carry out the above test with one of the
output relays configured to the corresponding set point group. The “Trip” LED
should illuminate and extinguish as for the “Set Point” LED detailed above.
This test should be repeated for all output relays.
4.2.5 PV5: Liquid crystal display (M301 only)
There are no test routines for the liquid crystal display (LCD). The display itself can
be checked by moving around the unit’s menu looking for pixels (the dots on the
display used to form the text) that are obviously not working.
There is a backlight in the display that allows settings to be read in all conditions
of ambient lighting. It is switched on and off via the “LCD Backlight” setting under
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 3
Page 6 of 38

the “SYSTEM CONFIGURATION” menu heading. Check that it works if not

already being used during testing.
4.2.6 PV6: Establish local communications
Using a PC running the appropriate software establish local communications with
the unit. To be able to establish communications with the unit it is necessary to set
the communications settings in the PC’s software to the unit’s factory-set default
settings, unless the customer has already changed them. If the latter is the case
then the customers settings should be entered into the software.
The default communication settings are:
Comms protocol: RS485 Modbus & IEC870 Courier
Modbus address: 247
Modbus baud rate: 9600
Modbus framing: 1 start bit, 8 data bits, 2 stop bits, no parity
Courier address: 255
IEC870 baud rate: 9600
IEC870 frame: FT1.2, 11 bits
First, establish communications between the software and the M301 or M302 unit.
Should there be any problems in establishing communications with the M302 the
RESET button can be pressed and the unit will return to the default communication
settings. It is not essential to establish local communications with the M301
because any settings can be made using the front panel and values read using the
LCD display.
4.2.7 PV7: Set the real-time clock (M302 only)
If an M302 is being commissioned, the real-time clock will need to be set via the
communications port before setting can proceed.
4.2.8 PV8: Relay outputs (when fitted)
The relay outputs can be used either as alarm outputs which can be reset after the
alarm condition has gone or as pulsed outputs for external energy counter
applications (eg. kWh). The application to which each relay output has been
configured should be determined so that the appropriate test procedure can be
adopted.
Table 3 gives the expected state for each relay output. The exception to this is
when the relay outputs are configured as watchdog contacts, which have a
normally closed configuration.

4.2.9 PV8: Testing alarm outputs

To test the relay outputs it is only necessary to test their operation rather than test
each individual function that they can be configured to perform.
Any relay outputs that have been set as an alarm contact can be tested using a
continuity tester.
All four relay outputs can be tested at once by configuring the same setpoint to act
on all four relays then follow the procedure detailed in Section 4.2.4. The settings
detailed in Section 4.2.4 will have to be applied to the M302 using the
communications port and a PC running the appropriate software.
After the time delay of the set point group, all four relay outputs will change state.
The test should be carried out with the relay outputs being configured as normally
open and normally closed contacts.
The “Set Point” and “Trip” LED’s will also have illuminated to show that the
measured quantity has moved to the operate side of the setpoint and a relay output
has operated respectively (M301 only).
4.2.10 PV9: Opto inputs (when fitted)
To test the status inputs set both the opto inputs to be configured as pulse counters
in the OPTO INPUT menu.
Apply rated voltage and current to bring the unit into service.
Energise each status input from the dc auxiliary supply. The terminal connections
are shown in Table 4.
Status input 1 (S1) 2 (S2)
Terminal 19 (+ve) 20 (+ve)
18 (–ve) 18 (–ve)
Table 4 Status input connections

To check the operation of the status inputs when configured as pulsed input
counters, the counts for each pulsed input can be viewed from the measurement
display for the M301 model, and using the communications and a PC running the
appropriate software for the M302. Apply then remove the dc voltage to the
input, the pulse counter should increase by one.

4.2.11 PV10: Settings

These tests ensure that all the predetermined settings for the particular installation
(customer’s settings) have been correctly applied to the unit.
4.2.12 PV10: Apply settings
Due to the versatility of the M300, it is necessary to apply the application-specific
settings at an early stage of commissioning so as to avoid unnecessary tests and
setting changes.
There are two methods of applying the settings:
• Downloading them to the unit using a portable PC running the appropriate
software through a communications port. If a setting file has been created by
the customer and provided on a diskette, this will save time.
• Enter them manually via the unit’s operator interface (M301 only).
If the customer has changed the passwords to prevent unauthorised changes to
some settings, either the revised level 2 password should be provided or the
customer should restore the original password prior to commencement of testing.
Note: In the event that the password has been lost, a recovery password can be
obtained from ALSTOM by quoting the model and serial numbers of the
particular unit. The recovery password is unique to that M300 unit and will
not work on any other unit.
4.2.13 PV10: Verify settings
The settings applied should be carefully checked against the customer’s desired
settings to ensure they have been entered correctly. However, this is not
considered essential if a customer prepared setting file has been downloaded to
the unit using a portable PC running the appropriate software.
There are two methods of verifying the settings:
• Compare a printed copy of the settings from the unit with the customer’s original
setting sheet.
• Step through the settings using the unit’s operator interface and compare them
with the customer’s setting sheet (M301 only).
4.2.14 PV11: Voltage and current inputs
These tests verify that the accuracy of current and voltage measurement is within
the acceptable tolerances for the M300.
Before testing, the voltage and current connections to the unit should be
determined for the particular application so that the measured quantities can be
applied to the correct inputs. This can be determined from the external wiring to
the unit or the “Connection Mode” setting under the “SYSTEM MODES” heading
and reference to Table 5.

4.2.15 PV11: Voltage inputs

This test verifies the accuracy of voltage measurement is within the acceptable
tolerances.
Apply rated voltage to all the voltage transformer inputs, checking the magnitude
of each input using a multimeter and record the corresponding reading under the
“MEASUREMENT” column heading. During testing the A phase voltage must
always be energised with rated voltage to bring the unit into service. The unit’s
reading can either be in primary or secondary volts depending on the setting of
“Display Mode” under the “SYSTEM CONFIGURATION” heading.
If the “Display Mode” setting is “Secondary”, the measured voltage values on the
unit should equal the applied voltage.
Otherwise, if the “Display Mode” setting is “Primary”, the measured voltage values
on the unit should equal the applied voltage multiplied by the voltage transformer
ratio set using the “VT Primary” and “VT Secondary” settings under the
“SYSTEM MODES” column heading.
The measured voltage can be read directly from the LCD display on the M301 and
via the communications interface and a PC running the appropriate software on
the M302.
The acceptable tolerance is ±0.2% ± digital multi-meter accuracy.
4.2.16 PV11: Current inputs
This test verifies the accuracy of current measurement is within the acceptable
tolerances.
Apply rated current to each current transformer inputs, checking the magnitude of
each input using a multimeter and record the corresponding reading under the
“MEASUREMENT” column heading. During testing the A phase voltage must
always be energised with rated voltage to bring the unit into service. The unit’s
reading can either be in primary or secondary Amperes depending on the setting
of “Display Mode” under the “SYSTEM CONFIGURATION” heading.
If the “Display Mode” setting is “Secondary”, the measured current values on the
unit should equal the applied current.

Otherwise, if the “Display Mode” setting is “Primary”, the measured current values
on the unit should equal the applied current multiplied by the current transformer
ratio set using the “CT Primary” and “CT Secondary” settings under the
“SYSTEM MODES” column heading.
The current can be read directly from the LCD display on the M301 and via the
communications interface and a PC running the appropriate software on the
M302.
The acceptable tolerance is ±0.2% ± digital multi-meter accuracy.
4.2.17 PV12: Analogue outputs (when fitted)
This test checks the operation and accuracy of the analogue outputs.
The assignments of each of the four analogue outputs should have been
determined by the customer and installed as part of the settings of the unit.
The customer should also have calculations which give the expected values of each
analogue output for a given input condition, these should be referred to when
testing the analogue outputs. (In the absence of this information the expected
values of the analogue outputs should be calculated for a definite value of applied
voltage and current, given the settings applied to the unit).
Apply the definite voltage and current values as detailed in the calculations and
check the dc output current for each assigned analogue output with a multimeter,
the terminal allocations are given in Table 6. Check these values against the
expected values.
The acceptable tolerance is ±0.2% ± digital multi-meter accuracy.

4.2.18 PV13: Communication ports for remote communications

This test should only be performed where the unit is to be accessed from a remote
location. If the settings have been successfully downloaded to the unit using a
portable PC running the appropriate software then it has already been proved that
local communications can be established.
It is not the intention of the test to verify the operation of the complete system from
the unit to the remote location, just the unit’s communications port and, where
applicable, the protocol converter.
Connect a portable PC running the appropriate software to the incoming (remote)
side of the protocol converter and ensure that the communications settings in
application software is set the same as those on the M300.
Check that communications can be established with the unit and check that
measurements can be read by the communications. Check that the value seen on
the display agrees with the value given by the communications (M301 only).

4.2.19 PV14: DC input (when fitted)

If the opto-isolated dc input is being used, the range setting should be checked to
ensure it is correct. This range is usually supplied factory-set to the customer’s
preferred value and can be identified from the eighth character of the model
number and reference to Table 7. If necessary, the setting can be changed using a
jumper link internal to the units. (If it is necessary to change the jumper link seek
advice from ALSTOM.)
8th Character DC Input Range
0 No dc input
1 0 to200mV
2 0 to 5V
3 0 to 250V

4 0 to 20mA

Table 7 DC input range setting

The dc input should be tested by applying a known dc voltage or current, as

appropriate, and within the operational range selected, to the input terminals
(terminal 4 to positive, 3 to negative).
The percentage of ‘full-scale deflection’ should read from the “dc input” window
under the “MEASUREMENTS” heading for the M301 model, and using the
communications and a PC running the appropriate software for the M302.
Check that the displayed value is within 0.5% of the expected value.

Section 5. WIRING VERIFICATION TEST

Remove all test leads, temporary shorting leads, etc. and replace any external
wiring that has been removed to allow testing.
If it has been necessary to disconnect any of the external wiring from the unit in
order to perform any of the above tests, it should be ensured that all connections
are replaced in accordance with the relevant external connection or scheme
diagram.
The following on-load measuring test ensures that the external (customer) wiring to
the current and voltage inputs is correct but can only be carried out if there are no
restrictions preventing the energisation of the plant being monitored.
Note: The following tests alone are not conclusive that the phase connections to
the unit are correct. A phase angle measurement is required for conclusive
testing.
5.1 Voltage connections
Measure the voltage transformer secondary voltages to ensure they are correctly
rated and, if possible, check that the system phase rotation is correct using a
phase rotation meter.
Compare the values of the secondary phase voltages with the unit’s measured
values, which can be found under the “MEASUREMENT” column heading.
The unit’s reading can either be in primary or secondary volts depending on the
setting of “Display Mode” under the “SYSTEM CONFIGURATION” heading.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 3
Page 12 of 38

If the “Display Mode” setting is “Secondary”, the measured voltage values on the
unit should equal the applied voltage.
Otherwise, if the “Display Mode” setting is “Primary”, the measured voltage values
on the unit should equal the applied voltage multiplied by the voltage transformer
ratio set using the “VT Primary” and “VT Secondary” settings under the “SYSTEM
MODES” column heading.
The acceptable tolerance is ±0.2%, ± digital multi-meter accuracy.
5.2 Current connections
Measure the current transformer secondary values and check that their polarities
are correct by measuring the phase angle between the current and voltage.
If the unit is connected to a balanced system, ensure the current flowing in the
neutral circuit of the current transformers is negligible.
Compare the values of the secondary phase currents with the unit’s measured
values, which can be found under the “MEASUREMENT” column heading.
The unit’s reading can either be in primary or secondary amperes depending on
the setting of “Display Mode” under the “SYSTEM CONFIGURATION” heading.
If the “Display Mode” setting is “Secondary”, the measured current values on the
unit should equal the applied current.
Otherwise, if the “Display Mode” setting is “Primary”, the measured current values
on the unit should equal the applied current multiplied by the current transformer
ratio set using the “CT Primary” and “CT Secondary” settings under the “SYSTEM
MODES” column heading.
The acceptable tolerance is ±0.2%, ± digital multi-meter accuracy.

Section 6. FINAL CHECKS

The tests are now complete.

Ensure that all alarms and LEDs, as appropriate, have been reset before leaving
the unit.
If it is not necessary for the backlight to be left on, switching it off will marginally
reduce the burden on the auxiliary supply (M301 only).

Section 7. MAINTENANCE

The M300 units are fully numerical in their design, implementing all functions in
software. They employ a high degree of self-checking so that, for the majority of
failures that can occur within the unit, all functions will cease to operate and an
error will be flagged. Depending on the failure and the hardware options fitted to
the unit, the error will be seen as an alarm that can be accessed over the
communication channel or by the operation of a watchdog contact.
7.1 Remote testing
The M300 units are self-supervising and so require negligible maintenance.
Most problems will result in an alarm so that remedial action can be taken.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 3
Page 13 of 38

However, some periodic tests could be done to ensure that the unit is functioning
correctly. If the M300 can be communicated with from a remote point, via its
communication port, then some testing can be carried out without actually visiting
site.
7.1.1 Alarms
The alarm status should first be checked to identify if any alarm conditions exist.
The alarm records can then be read to identify the nature of any alarm that may
exist.
7.1.2 Measurement accuracy
The values measured by the unit can be compared with known system values to
check that they are in the approximate range that is expected. If they are, then the
analogue/digital conversion and calculations are being performed correctly.
7.2 Local testing
When testing locally, similar tests to those for remote testing may be carried out to
check for correct functioning of the unit.
7.2.1 Alarms
The alarm status LED should first be checked to identify if any alarm conditions
exist. The alarm records can then be read to identify the nature of any alarm that
may exist.
7.2.2 Measurement accuracy
The values measured by the unit can be checked against known values injected
into the unit via its terminal block. Suitable test methods will be found in Section 8
of this chapter which deals with commissioning. These tests will prove the
calibration accuracy is being maintained.
7.2.3 Check output contacts
Check that the output contacts are giving the correct output state.
7.2.4 Analogue outputs
Check that each analogue output is giving out the expected value using a
multimeter.
7.2.5 Additional tests
Additional tests can be selected from the Commissioning Instructions as required.

Section 1. GENERAL FAULT FINDING

1.1 Auxiliary power

The unit needs to have an adequate voltage applied to the auxiliary supply
terminals to operate. Check the rating label for the auxiliary supply voltage range
(this can be one of two ranges 24 to 70V dc only or 70 to 230V dc or ac volts) for
the unit. Using an appropriate voltmeter measure the voltage applied to the unit
and check that it is within the specified range.
1.2 System measurand inputs
The unit is synchronised to the voltage present on the A phase by a phase locked
loop circuit. Should this voltage not be present then the unit will be placed out of
service and the “out of service” LED will be lit on the M301.
Using an appropriate voltmeter, measure the voltage present at the voltage input
terminals and check it is within the range specified for normal operation of the unit.
Using a phase rotation indicator check that the voltages have been applied to the
unit in the correct phase sequence.
Taking great care that the current transformer secondary is shorted, insert an
appropriately rated ammeter into the current input circuits. After removing the short
circuit, check that the current flowing into the unit is within the specified range.
The same degree of care should be exercised when the ammeter is removed -
ensure the secondary of the current transformer is shorted whilst the ammeter is
removed.
If the measurements made are all within the normal operating values of the unit
and the measured power does not correspond with the values measured then the
polarity of the current transformers may be reversed. Carefully check the wiring of
the transformers to the unit. It would be helpful to short each of the current
transformer inputs in turn and note the resulting real power measurement before
contacting the factory or local representative for advice.
1.3 Communications
Check that other units on the communications bus are responding to the master
station. If some units are responding then, by deduction, the break in the bus can
be determined. If there is no response from any of the units then reset the
communication port driving the bus with requests.
Check that there are not two units with the same address on the bus.
For Courier protocol systems the address cannot be allocated automatically unless
the address is first manually set to 0. Also check if the unit address has been set to
255. This is the global address for which no replies are permitted.
Check that the communication settings match those of the other units on the bus.
If the unit is an M302 and is not responding then the unit can be reset to the
default communication settings by pressing the reset button located beneath the
labelled grommet.
1.4 Analogue outputs (when fitted)
Check that the model has this option fitted via the user interface.
The analogue output terminals can be safely disconnected. Having done so,
connect a milliameter directly across the terminals and check that there is current
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 4
Page 2 of 2

flowing. If so, check the continuity of the current loop connected to the unit.
This can be done by using either a continuity device or by feeding a current into
the circuit from a dc constant current source. If there is continuity, then reconnect
the current loop to the unit and measure the voltage at the terminals using an
appropriate voltmeter. If the voltage exceeds 10V then the current loop has too
much resistance around it.
1.5 Output relays (when fitted)
Check that the model has this option fitted via the user interface.
Check that the voltage across the relay contacts falls to zero when the relay
operates.
1.6 Opto inputs (when fitted)
Check that the unit has this option fitted via the user interface.
Check for presence of a voltage at the terminals of the status inputs with an
appropriately rated voltmeter.
1.7 DC input (when fitted)
Check that the unit has this option fitted via the user interface.
Check for the presence of the correct signal at the terminals using an appropriately
rated multimeter.
1.8 Password lost or not accepted
The Measurement Centre is supplied with the password set to AAAA.
Only upper case letters are acceptable.
The password can be changed by the user. See Chapter 1.
There is an additional unique recovery password associated with the unit which
can be supplied by the factory, or service agent, if they are given details of the
unit serial number. The serial number will be found in the system data column of
the menu and should correspond to the number on the label located on the rear of
the unit. If they differ, quote the one in the system data column.
1.9 Sub assembly fault finding
If the unit continues to operate incorrectly having completed the above tests then it
will have to be returned to the factory for fault finding and repair. It is not practical
to repair the unit on site. If any PCBs are replaced the unit will need to be
recalibrated with equipment having a traceable accuracy of better than 0.05% of
reading. This level of equipment specification is not available for site working.
1.10 Recommended spares
A complete unit can be used to back up several Measurement Centres. In the very
unlikely event that one unit fails it can then be replaced with a complete new unit
and the faulty unit returned to the factory for repair. This will then become the new
spare unit once repaired.

Section 1. FRONT PANEL USER AND REMOTE ACCESS

INTERFACES

1.1 Introduction
The M301 has two principle means of allowing the user to interact with it; the front
panel interface and a remote communications access interface. This manual
specifies the data available to the user and the method by which the user can
interact with the database via the front panel interface. Also contained within the
document are the associated text strings that appear at the Courier remote
communications interface. The ModBus remote communications interface is more
basic and is described in the SCADA section. These systems implement a broad
range of standard facilities which allow the user to:
• View measurements
• View and change settings
• View (and reset where appropriate) alarm records
• View (and reset where appropriate) event records
• View (and reset where appropriate) alarm/error messages
Access to the unit’s database is provided by means of an intuitive menu system.
Human interaction is provided by means of a twenty character by two line LCD,
seven button keypad, and four LEDs.
The user interface provides textual information in one of four languages:
English
French
German
Spanish

1.2.1.1 Layer 0 - default position
The default position, at the head of the menu structure, allows the user to browse
through all available measurements. The unit’s display reverts to the default
position in the structure if there is no keypad activity for a pre-set time.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 5
Page 3 of 160

1.2.1.2 Layer 1 - primary column headings

The primary column headings logically break down the database into major areas
of common functionality such as:
System data
Communications Configuration
Analog Outputs, etc.
1.2.1.3 Layer 2 - secondary column headings
Secondary column headings sub-divide some primary column headings into further
logical areas of commonality.
1.2.1.4 Layer 2 - data
Layer two data is associated with primary column heading. Data includes setting
variables, fixed values or measured values. Password protection is employed on
the data.
1.2.1.5 Layer 3 - data
Layer three data is associated with secondary column headings. Data includes
setting variables, fixed values or measured values. Password protection is
employed.
1.2.1.6 Multi-layer - scan alarms
The scan alarms section is multi-layer; it is directly accessible from any other layer.
Scan alarms allows the user to view (and reset where alarms have cleared)
‘setpoint’, ‘relay trip’, ‘out of service’ and ‘alarm’ alarms.
1.3 Menu navigation
Basic menu navigation is described in Chapter 1 of both Volumes 1 and 2 of this
manual.
1.3.1 Scan alarms
The alarm scan mode is available whenever an alarm LED is illuminated. In this
situation the [READ] key can be used to scan through the alarm messages, which
can then be reset if so desired.
The [READ] key can be used to enter scan mode. If no alarm messages are present
then an intermediate screen will be displayed, otherwise the first alarm message
will be displayed.
If one or more alarm messages are present then the [READ] key allows the user to
step through the available messages, each press of the key selecting the next
message. After the last alarm message has been displayed the user will be
prompted by the message “ ‘CLEAR’ to clear alarms “. If the [READ] key is pressed
whilst this message is present, the display scrolls back to the first alarm message.
When viewing the message the [CLEAR] key can be pressed to clear the alarm
messages. If the [CLEAR] key is pressed and none of the alarms are still active, the
display returns to the previous menu layer via a temporary intermediate display
noting this fact. However, if there are alarms that are still active the “Alarms still
active” message is temporarily displayed before returning to the first remaining
alarm message. The [READ] key can then be pressed to scan through the standing
alarms again.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 5
Page 4 of 160

Pressing the “down” arrow key at any time returns the user to the display that they
left prior to entering the scan alarms menu.
If an alarm clears itself whilst it is being viewed by the user the alarm message will
be removed and the next alarm message displayed. If this happens when there are
no other alarm messages present, the display returns to that which it left on entry to
the Scan Alarms menu via a temporary intermediate display indicating that there
are no more alarms present.

reset alarms message in a cyclic manner.
[CLEAR] Resets/clears the alarm messages at the ‘CLEAR to
Clear Alarms’ prompt.

Summary of the key functionality whilst in the scan alarm mode.

1.3.2 General menu navigation for setting change

The user locates the data they wish to change as described in the introduction. The
data can then be selected by means of the [ENTER] key. This causes the menu to
enter setting mode. A flashing character, associated with the data, indicates that
data may be changed.
If the data chosen is fixed and the [ENTER] key is pressed the message “Not a
setting” will temporarily be displayed.
If a remote setting is in progress and the [ENTER] key is pressed the message
“Remote setting in progress” will temporarily be displayed and the user returned to
normal browsing mode.
Access to data is subject to password protection, so the process of changing data
automatically invokes prompting for the correct level of password, unless the
password protection has already been removed. Password protection, once
removed, remains active until the menu returns to the default display, due to either
the user returning the menu to the default display, or time-out of the keypad
inactivity timer.

Key Description of Function

Up arrow Increases the value of variable data in stepsize
increments up to the maximum value or step
up through available options in a cyclic
manner.
Down arrow Decrease the value of variable data in stepsize
increments down to the minimum value or
step down through available options in a
cyclic manner.
Right arrow This only has effect when there is more than
one field in the variable data (eg. password
or plant reference). It is used to move to the
next field to the right in a cyclic manner.
Left Arrow This only has effect when there is more than
one field in the variable data (eg. password
or plant reference). It is used to move to the
next field to the left in a cyclic manner.
[ENTER] This is used to select variable data when the value
is to be changed (ie. enter setting mode) and to
accept the value after the value has been changed.
It has no effect with column headings or fixed
data.
[CLEAR] This key is used to reset variable data to its
original value and to exit the setting mode.
The item of data that was to be changed then appears
in the browse menu as its original value.
[READ] Used to go to the scan alarms layer if any data is
present, otherwise no effect.

Summary of the functionality of keys for setting change.

1.4 Procedure for changing settings

The following section details the procedure for setting changes.
1.4.1 Start point
It is assumed that the general menu navigation has been followed to display the
item to be modified and, for example the following is displayed.
Language:
English

Pressing the [ENTER] key initiates the password prompt. If no password is required
or the password for the required level of protection has already been entered this
stage is be omitted.
1.4.2 Password protection
The password protection is described in the introduction. The procedure outlined in
that section should be followed to allow the correct password access to be set.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 5
Page 6 of 160

1.4.3 Setting change

Language:
English

Again the leading character flashes between its present value and an underscore
to prompt the user that the field may be changed. The numeric value or text string
will be varied by means of the Up and Down arrow keys. (If more than one field is
present eg. register bits, selection of the individual fields is provided by means of
the left and right arrow keys.
Pressing the [ENTER] key accepts the change and the menu returns to normal
browsing mode but the new data value is displayed.
Pressing the [CLEAR] key at any point aborts the setting change and the menu shall
return to browsing mode via a temporary intermediate screen that states “Setting
Aborted”. Time-out of the keypad inactivity timer aborts the whole process and the
menu returns to the default position.
1.4.4 Group settings
If the setting cell is a member of a group setting, the setting change is not
implemented until the user moves up to a primary column heading. This is because
the user may wish to change several related settings that should be implemented
together. Time-out of the keypad inactivity timer, at any stage of this process,
causes all the amended settings within that group to revert to their original values
prior to the change.
After making all the required group setting changes the user returns up the column
headings by pressing the Up arrow key. If any of the group settings have changed
the user shall be prompted by the following display. If no settings were actually
changed the prompt is bypassed.
Update Settings?
ENTER=Yes CLEAR=No

Pressing the [DOWN] key returns the user to the first data cell of the column
heading, with any previous changes still visible.
Pressing the [ENTER] key implements the settings and the menu moves to the
column heading via an intermediate message.
Pressing the [CLEAR] key discards the group settings change and the menu moves
up to the column heading via a temporary intermediate message.
1.4.5 Immediate settings
If an immediate setting has been altered and the [ENTER] key pressed the setting is
updated immediately.
Pressing the [ENTER] key implements the setting change immediately and returns
the menu to normal browse mode.
1.5 Menu Contents
The following sections depict the format of data that is displayed at the front panel
and remote access point in order to view the data base of the unit.

Section 3. MODBUS SCADA INFORMATION

3.1 ModBus protocol

The M300 implements a subset of the AEG Modicon ModBus RTU serial
communications standard. ModBus is a single master multiple slave protocol
suitable for a multi-drop configuration as provided by the RS485 connection. Up to
32 devices can be connected in this way.
3.2 Transactions
Communication will operate on a master-slave basis where only one device (the
master) can initiate transactions called ‘Requests’. The other devices (slaves)
respond by supplying the requested data to the master. This is called the ‘Request -
Response Cycle’.
Master to slave request
Device address Function Code nx8 bit data bytes Error check
Slave to master response
Device address Function Code nx8 bit data bytes Error check
3.2.1 Request
This master to slave transaction takes the form:
Device address: master addressing a slave
Function code eg. 03 asks the slave to read its registers and respond with their
contents.
Data bytes: tells the slave which register to start at and how many registers to
read.
3.2.2 Response
This slave to master transaction takes the form:
Device address: to let the master know which slave is responding.
Function code: this is an echo of the request function code.
Data bytes: contains the data collected from the slave.
3.2.3 Request-response cycle example

3.3 Framing
There are two types of message framing for the serial communications, ASCII or
RTU. The Measurement Centre will only support RTU framing.
3.3.1 RTU framing
In RTU mode, messages start and end with a silent interval of at least 3.5 character
times (t1-t2-t3-t4 as shown below).
The advantage of this mode of framing is that it enables a greater character
density and a better data throughput. However, each message must be transmitted
in a continuous stream. If a silent interval of more than 1.5 character times occurs
before completion of the frame, the device flushes the incomplete message and
assumes that the next byte will be the address field of a new message.
Start Address Function Data CRC Check End

t1-t2-t3-t4 8 bits 8 bits n x 8 bits 16 bits t1-t2-t3-t4

The Cyclical Redundancy Check (CRC) field is two bytes, containing a 16 bit
binary value. The CRC value is calculated by the transmitting device, which
appends the CRC to the message. The receiving device recalculates a CRC during
receipt of the message, and compares the calculated value to the actual value it
received in the CRC field. If the two values are not equal an error results. The CRC-
16 calculation is an industry standard method used for error detection.
One frame is transmitted as 1 start bit, 8 data bits and 1 stop bits. If parity is
selected then the frame is transmitted as 1 start bit, 8 data bits, 1 parity bit and 1
stop bit.
Where n > 1 data is transmitted most significant byte first.
The CRC check is transmitted least significant byte first.
3.4 Supported functions and usage

3.5 Register map

The ModBus register map consists of the following columns:
Code, Address, Contents, Data type, Indicator, Values, Conditional, Register type,
Min, Max., Step, Passcode.
3.5.1 Code
Function codes as described above.
3.5.2 Address
16 bit register address starting from zero. Most ModBus master devices add
40001 decimal to the actual address of the register.
3.5.3 Contents
Description of parameters assigned to registers.
3.5.4 Data type
UNSIGNED INTEGER range 0...65535 one 16 bit register
32 BIT IEEE FLOAT range ±1.2 x 10-38 to ±3.4 x 1038 two consecutive
16 bit registers (most significant word occupies lowest
addressed register)
ASCII TEXT range 32...159 16 bit registers
(two ASCII codes per register)
BINARY FLAGS Each bit of a 16 bit register can be used as a binary flag.
3.5.5 Indicator
Each bit of a 16 bit register can be either assigned as flags or filled with binary
data.
3.5.6 Values
Definitions of settings and data values.
3.5.7 Conditional
Lists any dependencies that exist between settings.
3.5.8 Register type
Declares whether a register is to be a read/write register (setting) or a read
register (data).
3.5.9 Min, Max., Step
The minimum and maximum numerical range and the incremental step size.
3.5.10 Passcode
There is a numerical passcode that allows save/abort settings and a factory
accessible passcode constructed from the serial number that allows entry/exit to
and from the calibration and configuration settings.
3.6 Error responses
When a slave detects an error other than a CRC error, a response will be sent to
the master. The most significant bit of the function code byte will be set to 1 (ie. the
function code sent from the slave will be equal to the function code sent from the
master plus 128). The following byte will be an exception code indicating the type
of error that occurred.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 5
Page 84 of 160

Transmissions received from the master with CRC errors will be ignored by the
slave. The number of re-tries needs to be set in the master station software.
An example of an illegal request and the corresponding exception response is
shown below. The request in this example is to read registers 0201H to 0209H. If
these addresses are not supported in the slave then the following occurs:
3.6.1 Request message

Address Function Code HI LO HI LO CRC
01 01 02 01 00 08 6D B4

3.6.2 Exception response message

Address Function Code Exception Code CRC
01 81 02 C1 91

3.7 Exception codes

Code Name Meaning

01 ILLEGAL FUNCTION The function code transmitted is not one of the

functions supported by the slave.

02 ILLEGAL DATA ADDRESS The data address received in the request is not an
allowable value for the slave

03 ILLEGAL DATA VALUE The value referenced in the data field transmitted by
the master is not within range for the selected data
address

06 SLAVE DEVICE BUSY The slave is engaged in processing a long-duration

program command. The master should re-transmit the
message later when the slave is free

3.8 Event and disturbance record extraction procedures

3.8.1 Event record extraction
To read an event record, the user must first check that there are event records
stored in the unit. Register-30035 indicates the total number of event records
stored. The unit can store up to 100 event records.
If there are event records, then set register 40571 to the record number of the
record the user wants to read. The limits of this register are dependent on the
number of records currently stored in the unit. Record number 0 always displays
the latest record, and 1 the next previous record and so on. If there are no records
stored then register 40571 is not available.
After register 40571 has been set, the contents of the record are available in the
following registers:
Register 30036: Event type of the event.
There are four types of event records.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 5
Page 85 of 160

If the event type is 0 - Alarm event, then the following registers contain the record
information:
Register 30037: Time stamp
Register 30043: Alarm type
Note: Other registers not listed above within the range 30043 ... 30052 are not
available.
If the event type is 1-Setpoint event, then the following registers contain the record
information:
Register 30037: Time stamp
Register 30046: Setpoint group
Register 30047: Setpoint element
Register 30046: Setpoint parameter
Register 30049
/30050: Setpoint value when the setpoint
exceeded alarm threshold.
Register 30051: Setpoint level indicates whether the
setpoint is operated on the high or low alarm.
Register 30052: Setpoint trip/reset indicates whether the
record is logged during the setpoint trip or reset
operation.
Note: Other registers not listed above within the range 30043 ... 30052 are not
available.
If the event type is 2-Output contact change, then the following registers contain
the record information:
Register 30044: The first 4 bits represent the status of the 4 relay outputs of the
unit. Logical ‘1’ means that the output has ‘operated’. However, it does not mean
that the contact has ‘closed’ or ‘opened’. The actual state of the contacts depends
on the setting ‘Relay # Default State’. The unit logs this type of event only when the
setting ‘Relay # Assignment’ is set to Setpoint or Watchdog.
Note: Other registers not listed above within the range 30043 ... 30052 are not
available.
If the event type is 3 - Opto input change, then the following registers contain the
record information:
Register 30045: The first 2 bits represent the status of the 2 opto inputs of
the unit. Logical ‘1’ means the opto is ‘ON’. The unit
logs this type of events only when the setting ‘Opto Input
# Configuration’ is set to Logic Level.
Note: Other registers not listed above within the range 30043 - 30052 are not
available.
3.8.2 Disturbance record extraction
To read a disturbance or a waveform analysis record, the user must first check that
there are records available by reading the register 30054 which gives the total
number of records stored in the unit. The unit can store 1 waveform analysis record
and up to 4 disturbance records depending on the setting ‘Record Configuration’.
SERVICE MANUAL R8605A
M301, M302 Volume 2
Chapter 5
Page 86 of 160

Register 30054 gives the total number of records stored in the unit including both
disturbance and waveform analysis records.
Then set the register 40567 to determine the type of record you want to read. ‘0’
is to read waveform analysis record, and ‘1’ disturbance record. If the disturbance
record is selected, the register 40568 must be set to select the record number.
Record number 0 selects the latest, and 1 the previous one, and so on.
Register 40568 is not available if the waveform analysis is selected because there
is only one waveform analysis record.
Registers 30055 ... 30067 contain information about the record to be extracted.
Register 30055 ... 30060: Time stamp of the record
Register 30061: Available channels. The unit can stored up to 10
channels of data. The total number of bits set
indicates the number of channels stored in the
record.
Register 30062: Channel types. Indicates whether the valid channel
shown in register 30061 is an analogue or digital
channel.
Register 30063: Total number of samples stored per channel.
Register 30065: Number of samples of the selected page which is set
via register 40570.
Register 30066: Trigger position of the record.
Register 30067: Time base. A scaling factor used to convert the
samples of timer channel (channel 0) to a real time
value in seconds.
Register 30068
to30081: Individual scaling factor per analogue channel. It is
used to multiply with the samples read from the
corresponding analogue channel.
Register 30082
to 30151: Analogue channel names.
Register 30152
to 30389: Digital channel names.
The data of a record is extracted on a per channel basis. First select the channel to
be read by setting register 40569 to the correct channel number. Channel number
0 is the timer channel which is excluded from bit value shown in register 30061,
Available Channels (it is always there). Channel number 1 is bit-0 (right to left)
shown in Available Channels and so on.
Each channel of data is extracted on per page basis. The total number of pages of
a selected channel is shown by register 30064. Each page can contain up to 64
samples of data. To read a page of data, first set register 40570 to the required
page number, and from the value read back from register 30065 determine the
number of samples available in the page. The availability of registers 30390 ...
30453 depends on the number of samples of the selected page.
The information presented in the Disturbance/Waveform Analysis Menu is
sufficient to construct a record based on the COMTRADE format (both
COMTRADE: 1991 and COMTRADE: 1996 specifications are supported).
