3.2.2. Before start

The following procedures are based on the assumption that the commissioning action
described in the Installation instruction book of Alfa Laval’s Fuel Conditioning Module has
been successfully performed.

1. Switch on the EPC with the switch inside the cabinet (fig. 26).

Fig. 26. Switch inside the cabinet

NOTE:
In the simulator it is assumed that the EPC is already switched on.

2. Set automatic filter switch in “auto” position (fig. 27). In this position the filter is
hard wired to start when the respective pump is started (supply pump if filter is after
the supply pumps, or circulating pump if filter is after the circulating pumps).

Fig. 27. Automatic Filter switch

26
3. Set regulating valve switch in “EPC” position (fig. 28).

Fig. 28. Regulating valve switch

4. Switch on the isolators on each starter (fig. 29).

Fig. 29. Main switch

NOTE:
If one pump starter is not available (due to maintenance or other reasons) the
unit cannot be started in EPC mode but has to be started manually.

27
3.2.3. Start – EPC mode

1. Set all four pump switches to the EPC position (fig. 30).

Fig. 30. Supply and circulating pump switches – EPC position

2. Press “Start” on the EPC. A question will appear in the display, “Start?” + = Yes
- = No” (fig. 31). Pressing the “+” button will start the system. Pumps and
heating will be started according to the module starting sequence.

Fig. 31. Starting EPC

Pre-selected supply pump is started. When pressure is above PT1 the alarm low
limit - system waits 30 seconds. Then (preselected) circulation pump starts.
When pressure is above PT2 the low alarm limit — system waits 30 seconds.
Then heating starts.

At start up: low pressure alarms are blocked for 4 minutes, or until the pressure is
above the alarm limit. Then the low pressure alarm delay time is as set with
parameter Fa9.

NOTE:
If the optional Automatic fuel change over function has been installed,
Automatic change over from DO to HFO will be as set with parameters Fa15
and Fa16.
28
Alternatively

1. Start the supply and the circulation pumps in the manual position (in any order)
(fig. 32).

Fig. 32. Supply and circulating pump switches – manual position

2. Start the EPC. (Heating will start if under setpoint.)

3. Set the stand-by pump switches to the EPC position.

4. Change the running pump switches to the EPC position. (The running pumps will
stop, and the pumps selected in the EPC will start.)

29
3.2.4. Stop - complete shut down

By stopping the system as follows, no alarm will be activated.

The system is designed so that the pumps cannot be stopped from the EPC controller even if
an error occurs in the controller.

The EPC can only start or switch pumps, but never stop them. For safety reasons, this has to
be done manually.

1. Press “stop” on the EPC (fig. 33).

Fig. 33. Stopping the heater

2. A question will appear in the display “Stop heater?”.

3. Heating will be stopped.
4. An instruction will scroll across the display “Stop pumps manually!”.

NOTE:
Wait until the system has cooled before stopping the pumps (if not already on
diesel oil).

5. Pumps can now be stopped in any order.

NOTE:
To increase the life-span of the pumps seals, it is recommended to stop (and
thus start) the pumps on diesel oil. Cold Heavy Fuel Oil subjects the seals to
more wear on start.

30
3.2.5. Stop – pumps remain on

Each set of pumps (circulating and supply) can be stopped independently of each other. For
example, when the engine is not in service, the supply pumps can be stopped, and the
circulating pumps (and heating) can remain running.

To stop the supply pumps but leave the circulating pumps on to circulate oil in the engine
fuel rail and heater circuit, the EPC should remain on so that the stand-by function is
activated.

Stop in the following order to avoid alarm and starting the stand-by pump.

1. Stop the stand-by supply pump (switch from “EPC” to “STOP”).

2. Stop the running supply pump (switch from “EPC” to ”STOP”).

NOTE:
The time allowed to stop the stand-by and running pump in 1 & 2 above is Fa9
seconds (factory default 8 seconds).

If you want the circulation pump to remain on leave switches in “EPC” position.

To restart the pumps, set the switches from “STOP” to “EPC”.

31
3.2.6. Pump operation

To change over the running pump(s) during normal operation change Pr1 or Pr2 (see
“Parameter list” chapter in the FCM application).

NOTE:
To increase the life-span of the pump seals, it is recommended to minimize the
number of starts and stops on Heavy Fuel Oil.
Keep the same pump running as long as possible. It is recommended to change pump
in connection with the regular service overhaul of the pump.

The control unit can be set to change pumps (running to stand-by, and stand-by to running)
at preset intervals during operation.

Alternatively, the control unit can be set to indicate when the time has come to change over
pumps.

3.2.7. Pump stand-by function

The pump stand-by function is always active when the four pump switches are in the “EPC”
position and the EPC is on (indicated by the green LED next to the START / STOP button).

NOTE:
When a stand-by pump has been started due to a fault and there is a need to change
back to the stopped pump or enable the stopped pump as the stand-by, it is necessary
to check the setting of parameters Pr1 or Pr2 and change them to suit the required
pump selection.

Automatic change over of pumps always changes the selected running (running / stand-by)
pump parameter Pr1 or Pr2.

If there is a fault on one pump (e.g. one of the supply pumps) the stand-by function
continues to be active on the other pump set (e.g. circulating pumps).

The stand-by function has two different time delays:

- When the running pump contactor opens (perhaps due to over-current protection),
there is a 2 second delay before the stand-by pump contactor closes.

- When a low pressure alarm is received the time before the stand-by pump starts is
determined by parameter Fa9 (factory default of 8 seconds).

32
3.3. Oil operating modes

The controller works with two different control modes (set with the control mode button on
the EPC): DO control mode, and HFO control mode (fig. 34). The EPC controller has thus
two sets of setpoints and alarm limits, one set for each mode. The fuel modes are indicated
by respective LED's. Heating control is carried out depending on the selected mode.

Fig. 34. HFO/DO mode button

In connection with bunkering, it may be necessary to adjust some of the parameter settings.
This is certainly the case when changing to an HFO that is of a much different grade. Some
of the following parameters may have to be changed:

- Density parameter Pr23. If changing to an oil of a different density, change the

density parameter in order to obtain the most accurate viscosity measurement.

- HFO temperature setpoint parameter Pr30. The new oil must be heated to a
different temperature (as this temperature set point is used for the end of the
temperature start ramp) to obtain the same viscosity setpoint.

- Temperature Pr32

3.3.1. Heating function from OFF to DO

When the control unit is switched ON to DO mode (for temperature control), the fuel oil
temperature and viscosity are monitored and displayed.

The heating start sequence is controlled by Fa31, temperature start ramp, which allows the
oil to be heated to the set temperature within a set time. (If Fa31 = 0, the ramp function is
inhibited, and the control unit regulates directly using normal set points, alarm limits etc.).
The TT LED flashes during ramp function.

When the fuel oil temperature is within 3° C of the set temperature, the start ramp is stopped
and normal temperature control is initiated. The TT LED changes to steady shine.

- Low viscosity and low temperature alarms are disabled during start ramp.

- At the beginning of the start ramp, a maximum time is set for start ramp duration to
ensure that it does not run for too long a time. An alarm is activated if the start
ramp exceeds maximum time, See the “Alarms and Fault Finding” chapter in the
FCM application.

33
3.3.2. Heating function from OFF to HFO, or DO to HFO

To change from DO to HFO

1. Press the DO / HFO button (fig. 35).

Fig. 35. Changing oil mode

2. A question appears in the display. “Change oil mode? + = yes, - = no”

3. Press “+” to start the charge over.

4. If an electric or pneumatic change over valve is fitted the valve will immediately
start changing over to HFO.

NOTE:
If the electric valve with the change over ramp function is installed the
change over time can be set with factory parameters Fa12 and Fa13.

When the control unit is switched ON to HFO, or switched from DO to HFO, the fuel oil
temperature and viscosity are monitored and displayed. The start sequence is controlled by
Fa30, temperature start ramp, which allows the oil to be heated to the set temperature within
a set time. The VT LED flashes during ramp function; the TT LED shines steadily if
change-over from DO to HFO has been made, but does not shine if change-over from OFF
to HFO has been made. (If Fa30 = 0, the ramp function is inhibited, and the control unit
regulates directly using normal set points, alarm limits etc.)

On change-over from DO to HFO, heating of the oil begins when the controller detects an
increase in viscosity, indicating that Heavy Fuel Oil is entering the system.

Heating is paused if the controller detects a decrease in viscosity during the start ramp.

34
When the temperature has reached 3° C below the temperature set value of HFO, the control
unit automatically switches to viscosity control. When the TT LED switches off and the VT
LED shines steadily, the start sequence is complete and viscosity control attained.

- Low viscosity and low temperature alarms are disabled during start ramp.

- At the beginning of the start ramp, a max. time is set for start ramp duration to
ensure that it does not run for too long. An alarm is activated if the start ramp runs
to max. time.

- When changing over for DO to HFO and vice versa the viscosity at 50° C is
displayed in the Instantaneous values list. This makes it possible to see how much
DO to HFO is in the system at the usual reference temperature of 50° C.

3.3.3. HFO control heating mode

HFO control type

The HFO control type (temperature or viscosity), is set in parameter Pr19. The selected type
is shown by the sensor LED's on the display.

If the viscosity sensor (VT) LED is lit, the unit is in viscosity control.

If the temperature sensor (TT) LED is lit, the unit is in temperature control.

3.3.4. Change-over from HFO to DO

When a change is made from HFO to DO, the control unit continues to control the fuel oil
viscosity. The viscosity value is maintained by decreasing the temperature of the HFO-DO
blend. The TT LED is flashing and the VT LED shines steadily.
When the temperature reaches the DO set value, the control is automatically switched over
to DO mode (temperature control). The TT LED then changes to steady shine, and the VT
LED switches off.

3.3.5. Automatic change-over – HFO / DO

Engine conditions
The EPC controller can be configured to change between DO and HFO based on engine
conditions. There are two alternatives:

1. Auto change-over – input signal

The controller receives information from the diesel engine control system on
whether or not the conditions are right for HFO operation. If the conditions are
right during a two minute period, the controller can be set to either change over
automatically, or simply display that the engine conditions are met.

2. Auto change-over — relative engine consumption

The controller will change to DO when the engine percentage consumption is

below a set limit for a two minute period.

During the two minute delay in both cases, the change-over process can be aborted by
pressing the DO / HFO button. The function is then cancelled for 20 minutes. If a permanent
cancellation of the function is required, the corresponding parameter must be set to zero.

For further information, see the “Parameter List” chapter in the FCM application.

Heater fault
In the event of a heater fault it is possible to arrange for a controlled change over to DO.

The automatic change over valve has to be installed; then by using parameter Fa14 the
system can be set to automatically change over to DO in the event of a heater fault.

It is recommended to set Fa14 to a lower value than the low temperature alarm limit. When
the set low temperature limit is reached, the change-over countdown timer (2 minutes) starts.
The DO LED next to the DO / HFO change-over button starts flashing, and a text appears
intermittently showing the time to change-over. The change-over countdown timer can be
aborted by pressing the DO / HFO pushbutton.

3.3.6. DO to HFO to DO valve time

When the electric change-over valve is installed the new fuel can be introduced into the
system gradually by regulating the time it takes for the change-over valve to change from
DO to HFO, or HFO to DO. Although this will be strongly influenced by the level in the
respective HFO and DO service tanks.
See parameter Fa12 and Fa13.

36
3.4. Mixing tube deaeration

If mixing tube needs venting during operation, an alarm will be activated.

If automatic deaeration function is installed, the mixing tube will be automatically

deaerated. If the automatic deaeration valve is open for more than 120 seconds, an alarm
will be activated.

3.5. Manual operation

These functions are provided in the unlikely event that the EPC50B is not working. They
enable components within the system to be operated independently, direct supervision by the
operator will be required.

The module is equipped with visual indicators - thermometers, pressure indicators, position
indicators - that can be used when the EPC is not working.

3.5.1. Manual operation of parts of the system

Pumps
Pumps can be operated manually by switching the pump switch to the manual position.

NOTE:
If both pump switches (for one pump set) are set to “manual”, the pump which was
switched on first will be the one running. If the contactor of the pump in operation is
released, for example, by the motor protection, the other pump will start.

If the EPC is switched off or stops working during operation, the running pumps will
continue running (with the selector switches in the EPC position). After the I / O board has
been replaced the EPC will take over control when switched on again.

If the pumps have to be run for a longer time without the EPC in control, it is recommended
that the pump selectors are switched to manual position.

37
Heating
Heating can be controlled by the EPC50B (if it is working) even if the pumps are run
manually. Pressing the start button on the EPC will start the heating.

The heating media control valve can also be activated directly by first switching the heating
media control valve from EPC to manual, then using the switch to activate the valve to open
or close as necessary (fig. 36).

Fig. 36. Heating media control switches

There is also a hand lever under the cover of the valve actuator.

For electric heating the fixed loads within the power unit can be switched on step wise, in up
to 5 steps (depends how big the heater is as to the number of elements and the number of
steps).

Automatic filter
The Alfa Laval Automatic filter can remain in the “Auto” position, even when the EPC50B
is not working, because it is hard wired to start when the pump before the filter is started.

The Alfa Laval Automatic filter can alternatively be switched on in the manual position to
start the filter when the pumps are not working.

The automatic drain function is not working if the EPC50B is not working.

The filter then needs to be drained manually at regular intervals (every 8 hours) by putting
the filter switch in the DRAIN position (for about 10 seconds). The filter can also be
manually drained by using the by-pass valve.

HFO / DO change-over valve

The HFO / DO change-over valve can be maneuvered with the hand lever. (It will be
necessary to change Fa12 to disable the change-over valve from the EPC, if the EPC is still
ON)

38
3.6. Automatic start up after power failure

The module can be set to be automatically restarted after a power failure, and if an alarm
should be activated or not, with a software parameter; see the parameter list.

When the electric power returns after the power failure, the supply pump, circulating pump
and heater are restarted again (after a set delay time) with one second intervals. The same
pumps that were running before the power failure will be restarted. If, however, the power to
the EPC is not interrupted, the standby pump will be started and alarm activated when power
to the pumps returns.

3.7. Regular checks on the system

Regularly check the process values to note any unusual changes. Also, regularly check the
automatic filter pressure drop indicator.

If SRV position (or instantaneous electric heater power in the case of electric heater)
changes dramatically, this could be an indication of heater clogging, provided other process
criteria remain the same.

When the outside ambient temperature is high, regularly check the internal control panel
temperature (see parameter list Pr7). This should be max. 70° C.

39
3.8. Remote control and monitoring

The fuel conditioning module is prepared for 4 levels of remote control.

The levels are:
1. Basic Level 1
2. Extended Level 2
3. Advanced Level 3
4. Fully automated Level 4

It is important that you firstly identify which level of automation is installed.

NOTE:
Every module is prepared for Remote Control, and the pump mode selection
switches indicate this with their 4 positions: MANUAL / OFF / EPC / REMOTE.
This does not mean there is a remote control location.

3.8.1. Basic Level 1

Operation is dependent on the functions installed by the automation supplier.

Possible remote features:
- Fuel mode change-over DO / HFO
- Heating start / stop
- Common alarm
- High temperature / low viscosity
- High viscosity / low temperature
- Automatic filter differential pressure high
- Fuel oil pressure low
- Switched to stand-by pump
- 4-20 mA, 2 outputs
- Temperature signal
- Supply pump 1 running
- Supply pump 2 running
- Circulating pump 1 running
- Circulating pump2 running

NOTE:
Alarm accept / reset has to be made at the EPC50B operators panel on the fuel
conditioning module.
40
3.8.2. Extended Level 2

Extended Level 2 – features

NOTE:
Alarm accept / reset has to be made at the EPC50B operators panel on the fuel
conditioning module.

The local pump selection switches have to be set to “remote”. If you intend to change the
running / stand-by pump selection during operation, the switches have to be in “EPC”
position (as all pump selection is made from the EPC). First check that the pump mode
selection switches on the remote panel are in the “EPC” position.

3.8.3. Advanced Level 3

Advanced Level 3 – features

NOTE:
Alarm accept / reset is possible with the remote operators panel.

The local pump selection switches have to be set to “remote”. If you intend to change the
running / stand-by pump selection during operation, the switches have to be in “EPC”
position (as all pump selection is made from the EPC). First check that the pump mode
selection switches on the remote panel are in the “EPC” position.

3.8.4. Fully automated Level 4

When the remote control is via a fieldbus from the central automation system, operation is
as per the automation system makers instructions.

2. Delomatic Power Management System (PMS) - introduction
The DELOMATIC system for control and protection of generator plants is able to combine
the following functions into one interactive system:

• Power management system (PMS) functions

• control of generator set(s)
• control of shaft generator
• supervision of tie breaker
• an extensive number of integrated protective functions
• measurement of all relevant AC-values
• system logic
• serial communication interface

The DELOMATIC system is able to carry out control of several generator sets within the
interactive system.

The DELOMATIC system consists basically of a Deif Generator Unit (called DGU) and a
corresponding Control Panel, (called CP) for each generator set. Each DGU may have as
many as 3 corresponding control panels.

The internal communication between the DGU and the corresponding control panel(s) are
carried out by an ARC-network (local area network). By using a network for
communication between the DGUs, very high transmission rates and maximum flexibility
regarding placement of the DGUs is achieved.

If more than one DGU are included in the DELOMATIC system the ARC-network is used
for exchange information between the DGUs regarding e.g. PMS commands, system status,
DGU status as well as communication between the DGU and the corresponding CP(s).

The application software, which consists of two main software units: the generator control
software unit and PMS software unit, controls the DELOMATIC system.

DGU no. 1 (Master DGU) contains the Power management system (PMS) software unit. All
DGUs (incl. the Master DGU) in the DELOMATIC system contain the generator control
software unit and a PMS interface.

The PMS software unit controls and supervises all common PMS functions in the
DELOMATIC system according to the functionalism of the selected plant mode, e.g. the
SEMI-AUTO or the AUTOMATIC plant modes.

The PMS interface forms a bi-directional communication link between the PMS software
unit and the generator set control software units. The PMS software unit transmits e.g. PMS
start/stop commands and selected plant mode via the PMS interface. The generator set
control software unit(s) transmits signals such as the generator sets operational status (e.g.
running or stand-by), relevant measured and calculated values, and the status of the selected
control mode (PMS control or SWBD control) for the generator set.

51
The generator set control software unit controls and supervises all local operations of the
generator set. The received PMS commands may initiate e.g. start and stop of the generator
set but the generator set control software unit carries out the actual control, protection and
supervision of the generator set.

The programmable DELOMATIC set-points and timers

The DELOMATIC system is controlled according to a number of programmable set points
and timers (jointly called the system setup).

The operator may program the set points and timers by means of the DELOMATIC menu
system which is accessible through the control panels.

The DELOMATIC menu system offers:

• access to set points and timers used for control of the integrated PMS
• access to set points and timers used for local operation of the generator sets
• access to set-points and timers used for the supervision and protective functions
• read-out of measured and calculated values
• system selections
• alarm handling

The Control Panel (CP)

The CP is a slave unit, which operates according to received information from its
corresponding DGU! All information between the DGU and corresponding CP are
exchanged through the ARC-network.

All measured values and programmed system setup are stored in the DGU. This (and the
separate power supply terminal) enables the DELOMATIC system to continue operation
even if a break-down occurs in a CP.

The control panel offers:

• display and control of the DELOMATIC menu structure access to set-points and
timers
• access to system selections
• read-out of measured and calculated values
• system status
• operator alarm handling interface
• display of alarm messages
• status by means of LED's

The CP forms the operators interface with the DELOMATIC system by means of:
• 2 lines, each with 16 characters LCD display incl. background light controlled by a
dimmer input
• 5 edit and programming push-buttons
• 16 status LEDs (with 3 possible colors)
• 10 control push-buttons

52

2.5. Hardware configuration of DGUs

The hardware configuration of the Master DGU is different from the rest of the DGUs. This
is due to the fact that the Master DGU is handling the common functions e.g. such as
conditional connection of heavy consumers, and therefore requires additional inputs and/or
outputs.

The Master DGU is configured with the following hardware modules:

• 1 Power Supply Module (PSM-1)

• 1 Control Module (CM-2 incl. comm. Port RS 485)
• 2 Input Module (IPM-1)
• 2 Output Module (OPM-1)
• 1 Synchronising, Control and Measuring module (SCM-1)
• 1 Current Relay Module (CRM-1, diff.)

DGU no. 2 are configured with the following hardware modules:

• 1 Power Supply Module (PSM-1)

• 1 Control Module (CM-2)
• 1 Input Module (IPM-1)
• 1 Output Module (OPM-1)
• 1 Synchronising, Control and Measuring module (SCM-1)
• 1 Current Relay Module (CRM-1, diff.)

DGU no. 3 are configured with the following hardware modules:

• 1 Power Supply Module (PSM-1)

• 1 Control Module (CM-2)
• 1 Input Module (IPM-1)
• 1 Output Module (OPM-1)
• 1 Synchronising, Control and Measuring module (SCM-1)
• 1 Current Relay Module (CRM-1, diff.)

61
3. Alarm system

3.1. Alarm handling

The alarm handler is a software function, which handles all alarms registered by the
DELOMATIC system.

The alarm handler may be activated by:

• External alarm signals
• Internal DGU system supervision
• Internal generator set supervision
• Internal PMS supervision

The alarm handler will examine every registered alarm, activate the designated alarm
sequence and display the corresponding alarm message.
When a new alarm is registered:
• the LED "ALARM MESSAGE SEE DISPLAY" will start flashing red
• the corresponding alarm message will be displayed at the CP
• the corresponding alarm sequence will be carried out

Display of alarms
The alarm messages are displayed at the text line.

"ALARM MESSAGE"
No:xxx F:Y U-ACK

All alarm messages concerning a specific generator set (DGU) will be displayed at the
corresponding CP.
All alarm messages concerning common PMS functions will only be displayed at the
corresponding CP for the Master DGU.

3.2. Alarm types

The alarm handler distinguishes between System alarms and PMS alarms.

System alarms (system supervision)

A system alarm indicates a failure, which may prevent the DGU to operate as expected. A
system alarm may be caused by communication error, power supply failure or in/output
error and similar.
A registered system alarm will be indicated by:

• an active SYSTEM ALARM output

62
PMS alarms
A PMS alarm may be considered to be caused by a "normal" event meaning that the
DELOMATIC system is fully operational and handling the event(s) as expected.

A registered PMS alarm will be indicated by:

• an active PMS ALARM output

3.3. Alarm sequences

The alarm sequences are designed to take appropriate action according to the severity of the
event which caused the alarm.

The DELOMATIC system is implemented with several different alarm sequences:

• Warning
• DG Block
• Safety stop
• Trip of GB
• Shutdown

Warning
The purpose of the warning sequence is to inform the operator of "nice to know" events. The
DELOMATIC system will not take any action but only display an alarm message.

Activation of the warning sequence will:

• start flashing the LED "ALARM MESSAGE SEE DISPLAY" red
• display the designated alarm message at the CP
• activate the horn output
• set one of the alarm type outputs (SYSTEM or PMS)
The operator is able to reset the horn output by pressing the "RESET HORN" push-button.
This will not have any influence on the further alarm handling.

DG Block
The DG block alarm sequence is used for blocking any further automatic functions, which
will lead to connection of the generator set, if a situation (electrical or mechanical) occurs
due to which it is inadmissible to connect the generator set to the busbar.

Activation of the DG block sequence will:

• carry out the warning sequence.
• block all automatic functions which will lead to a connection of the generator set.
• block closing of the generator breaker in question.
(the DG block sequence will not open or trip the generator breaker if it already is closed,
when the block alarm becomes active)
• transfer the PMS start command to the next stand-by DGU.

63
Safety stop
The safety stop sequence is used to carry out a previous intervention and stop a defective
engine, instead of waiting until a critical condition becomes fatal for the engine.

Furthermore, the safety stop alarm sequence can prevent a possible black-out situation at the
busbar as it replaces the defective generator set before a shutdown occurs on a running
generator set.

The safety stop sequence starts and connects the next stand-by generator set to the busbar
according to the chosen start priority. When sufficient available power is measured at the
busbar the defective generator set is disconnected and stopped (incl. cooling down etc.).

Activation of the safety stop sequence will:

• carry out the warning sequence (alarm message causing the situation)
• transmit a PMS start command to the next stand-by generator set
• connect the next stand-by generator set to the busbar
• display alarm "Safety Stop" on the CP for the defective DG
• disconnect and stop the defective generator set (incl. cooling down etc.) block for a
new start of the defective DG
• carry out the blocking alarm sequence

An active safety stop alarm sequence is indicated by:

• a red "SAFETY STOP" LED at the CP corresponding to the defective DGU

3.4. Alarm registration

All alarm messages are registered and stored in the alarm stack with statement of:
• status as first or not first received alarm
• status as an un-acknowledged or acknowledged alarm

3.4.1. Alarm stack

The alarm handler stores all registered alarm messages in chronological order (as registered
by DELOMATIC) in the alarm stack. The received alarms will be stored with the first
(oldest) alarm at the top of the stack.
The heading of the alarm stack is indicated by the following text at the CP display:

ALARM STACK
XXX ALARM(S)

The total number of un-acknowledged and acknowledged alarms stored in the alarm stack, is
displayed at the bottom line of the alarm stack heading.

66
The operator is able to jump to the top of the alarm stack from any location (outside the
alarm stack) in the DELOMATIC sub-menu structure by pressing the "NEXT ALARM"
push-button.

The operator is able to browse through the alarm stack by using the "⇑" and "⇓" push-
buttons on the CP:

ALARM MESSAGE 1
No:xxx F: U-ACK

Press "⇓"

ALARM MESSAGE 2
No:xxx F: U-ACK

3.4.2. Alarm ID. No

Every alarm in the DELOMATIC multi-function system is identified by an alarm
identification number.

LOW SUPPLY VOLT.

No: 8 F:Y U-ACK

The alarm identification number is used for a positive identification of alarms, e.g. when
corresponding with a DEIF service engineer. In the example shown above, the alarm for low
supply voltage is identified by the ID. No. 8.

3.4.3. First alarm

The first alarm status is designated to the first new alarm received by the DELOMATIC.

Some events may cause a chain reaction of further events, each generating an alarm. The
first alarm status may indicate which event was the first.

The alarm handler software is sequentially executed, which means that the status of the
internal alarm signals is examined once in every program scan. One program scan has an
approximate duration of 60 ms. If the DELOMATIC receives several internal alarm signals
within one program scan, the alarm signals which were "scanned" first will be designated
with the first alarm status.

If the alarm stack contains only acknowledged alarms the next new alarms registered will be
designated with the first alarm status. This means several "first alarms" may be registered in
the alarm stack simultaneously.

67
The first alarm is identified by the following code in the status line of the alarm message:

ALARM MESSAGE
No:xxx F:Y U-ACK

F:Y (First: Yes)

Any other alarms (registered later than the first alarm) are identified by the following code
in the status line of the alarm message:

ALARM MESSAGE
No:xxx F:N U-ACK

F:N (First: No)

3.4.4. Acknowledgement of alarms

Any alarm registered by the DELOMATIC system must be acknowledged by the operator,
in order to reset the action taken by the alarm sequence.

At the same time the operator becomes aware of any occurring abnormal events, even
though the condition which caused the alarm may have disappeared as a result of the action
taken by the DELOMATIC alarm sequence.

Each un-acknowledged alarm is identified by:

• a flashing LED "ALARM MESSAGE SEE DISPLAY" (red flash)

• the following status line in the display:

ALARM MESSAGE
No:xxx F:N U-ACK
Un-ACKnowledged
An active alarm is acknowledged by pressing the "ACK ALARM" push-button on the CP.
Acknowledgement of a still active alarm is confirmed by the following status line in the
display:
ALARM MESSAGE
No:xxx F:N --ACK
--Acknowledged

The operator is able to jump to the next un-acknowledged alarm when viewing the alarm
stack by pressing the "NEXT ALARM" push-button.

When only acknowledged alarms are present in the alarm stack then:

• the LED "ALARM MESSAGE SEE DISPLAY" will turn to a steady red light
68
Acknowledgement of active alarms
An active alarm means that the condition(s) which caused the alarm are still present or
active.
The acknowledgement results in a change of status for the alarm in question, from un-
acknowledged to acknowledged.

When the alarm condition(s) for an alarm with acknowledged status disappears, the alarm
message will be removed from the alarm stack and any actions made by the alarm sequence
are disabled without further notice.

Acknowledgement of in-active alarms

An in-active alarm means that the condition(s) which caused the alarm disappeared before
acknowledgement of the alarm.

An empty alarm stack

When there are no un-acknowledged alarms and no more active alarms:

• the LED "ALARM MESSAGE SEE DISPLAY" will turn off

• the alarm output(s) will be de-activated (PMS or DGU alarm outputs)

When the alarm stack is empty, it will no longer be possible to enter the alarm stack.
Furthermore the push-button "NEXT ALARM" becomes inactive.

3.5. Alarm list

The alarm list contains all alarm messages (listed in numerical order) in the DELOMATIC
system.

Note! Some of the alarm messages mentioned in this chapter may correspond to functions,
which may not be available in your specific DELOMATIC system.

The alarm list constitutes a very helpful and fast approach for the operator, in order to locate
a desired piece of information in the DELOMATIC technical documentation based on an
actual alarm text.

69
 The alarm list contains the following information:

• the alarm ID no
• the specific alarm text
• a brief description of the event(s) which activated the alarm, and the status after the
alarm handling
• which alarm sequence is dedicated to the actual alarm
• the references indicate in which chapter to find detailed information about any set-
points, timers and alarm conditions, which have influence on the generation of the
alarm message in question

The DELOMATIC menu systems, which are operated via the control panel(s), provide
access to all programmable set-points/timers, system selections and read-out of selected
measured values.

4.1. The menu structure

The DELOMATIC menu structure is based on 4 main sections. Each main section contains a
number of sub-menus.

SYSTEM MAIN MENU SYSTEM ALARM STACK

SETUP CP-MASTER DATA READINGS SELECTION XXX ALARM(S)

Fig. 16 The main sections of the DELOMATIC menu system

• The system setup section contains e.g. sub-menus for programming of set-points and
delays used for control of the DELOMATIC system.
• The data readings section contains read-out sub-menus for display of actual
measured values.
• In the system selections section, a number of system selections are available (only
visible on the CP for the Master DGU).
• The alarm stack contains the alarm messages for all alarms.

The operator is able to browse through the DELOMATIC menu system via the CP push
buttons:

Moves the focus to the left in the menu structure

5. Power management system

The Power management system (PMS) unit is the backbone of the DELOMATIC system.
The PMS unit controls all functions regarding superior or common control of the entire
power plant by means of PMS commands.

Fig. 17 Operating principle of the integrated PMS system

The PMS in the DELOMATIC system operates as an integrated unit in the Master DGU.

The PMS interface in each DGU carries out distributed control of the generator sets
according to the received PMS commands and PMS status feedback signals.

Only generator sets (DGUs) selected to be under PMS control are included in the automatic
PMS functions.

81
5.1. Plant modes
The DELOMATIC system operates according to the functionalism of the selected plant
mode.

The plant modes combine the automatic functions in the DELOMATIC system according to
the desired functionalism of each plant mode. This means some of the automatic functions
may not be used in all plant modes.

The system is able to handle the following plant modes:

• SEMI-AUTO MODE
• AUTOMATIC MODE
• SECURED MODE

The plant modes are only accepted by DGUs which are selected to be under PMS control.

Selection of the plant mode for the entire power plant is done by a set of push-button inputs
located on Master DGU.

5.2. SEMI-AUTO plant mode
The SEMI-AUTO plant mode is an operator dependent AUTO mode.

In this mode the automatic sequences are carried out only on request of the operator, via the
push-buttons at the CP-Master for the DGU; the automatic start sequence, the GB ON
sequence incl. dynamical synchronisation, the GB OFF sequence and the automatic stop
sequence.

Selection of SEMI-AUTO plant mode will have no effect on running generator sets.

Following push buttons at the CP-Master’s are only active when SEMI-AUTO mode is
selected.

PUSH-BUTTON DESCRIPTION
“START” Start of engine; the programmed automatic start
sequence is carried out.
“STOP” Stop of engine; the programmed automatic stop
sequence is carried out.
“GB ON” Closing of GB; the programmed automatic GB ON
sequence is carried out.
“GB OFF” Opening of engine; the programmed automatic GB
1)
OFF sequence is carried out.
1) The DELOMATIC will only open the GB if the generator set is expendable at the busbar.

NOTE ! Any auxiliary engines, which carry out idle run when SEMI-AUTO mode is
cancelled, are automatically stopped by the function for stop of non connected DGs.

5.3. AUTO plant mode

During this full-automatic mode, called AUTO mode, the automatic control is carried out by
all generator sets, which are selected to be under PMS control.

The DELOMATIC system carries out automatic frequency and load control during the
AUTOMATIC plant mode.

The busbar load is shared between the running generator sets either as:

• symmetrical load share

or
• asymmetrical load share

Load depending start and stop of the generator is are carried out according to the actual
power demand at the busbar with respect to: the programmed start/stop priority and the
programmed limits for start and stop.

If the DELOMATIC system detects a blackout situation at the busbar, a conditional blackout
start of two generator sets is carried out.

83
5.4. SECURED plant mode
The SECURED plant mode is almost the same as the AUTO mode. But the load depending
start/stop set-points are increased with the nominal power of the largest connected generator
set.

This means the nominal load of the largest connected generator set is available at the busbar
at any time during SECURED mode.

The SECURED plant mode ensures that in this way, any of the running generator set may
suddenly be cut-out from the busbar (e.g. by a shutdown or trip of GB alarm sequence) at
any time without causing an imminent black-out situation.

5.5. Load dependent start/stop function

The load dependent start/stop function is active when the AUTO or SECURED plant mode
is selected and shore connection is not closed.

The start/stop functions transmits PMS start and stop commands, which are based on a
calculation of how many generator sets are needed in order to satisfy the actual power
demand at the busbar.

The PMS start/stop commands cause the individual generator sets to carry out respectively
start and stop according to the programmed start/stop priority.

Furthermore, during SEMI-AUTO mode, the load depending start/stop functions operate as
hidden load supervision. The load depending start/stop function will only allow a push-
button initiated semi-auto disconnection of a generator breaker, if the generator set is
expendable at the busbar (the predicted available power > the nominal power of the
generator set).

Calculation of the load depending PMS start/stop commands is based on a comparison of the
programmed start and stop limits and a special DELOMATIC value called the predicted
available power.

84
5.6. Selection of Start/Stop priority
Depending on the programmed priority sequence and the operational status of the generator
sets, the start/stop priority function continuously designates each generator set with
respectively a PMS start priority and a PMS stop priority.

Fig. 18 Operating principle for determination of the start/stop priority.

The load depending start/stop function uses this information when the PMS start/stop
commands are to be transmitted.

NOTE: The start/stop priority function keeps account with which DGUs are "ready for PMS
start", and which DGUs are "ready for PMS stop". Any running DGU, which during
operation, becomes not "ready for PMS stop" are not accepted as the next generator to be
stopped.

5.6.1. Programming of the start/stop sequence

Programming and read-out of the start/stop priority sequence are carried out for all generator
sets through the CP corresponding to the Master DGU.

The DELOMATIC multi-function will not accept the start/stop priority sequence if:
• two or more generator sets are programmed to the same start/stop priority number
• a generator set is programmed to have several start/stop priority numbers
The example below shows a start/stop priority sequence for a 4 generator set power plant,
programmed to start priority 2-3-1-4.

START PRIORITY
2 - 3 - 1 - 4
DGU no.
START PRIORITY 1st 2nd 3rd 4th
85
NOTE!
The DELOMATIC system is able to control the start/stop priority for as many as 6 generator
sets.

When the operator changes the priority sequence, the generator sets automatically re-arrange
according to the new start/stop priority, any stand-by generator sets which have been
designated with a higher start priority than any running generator sets, will automatically
substitute these.

5.6.2 Determination of the start priority

The Master DGU continuously designates each generator set with a PMS start priority
number according to the programmed priority sequence.

The priority sequence 2 - 3 - 1 - 4 in the display designates:

• DGU no. 2 with start priority no. 1 (to be started first) .
• DGU no. 3 with start priority no. 2
• DGU no. 1 with start priority no. 3
• DGU no. 4 with start priority no. 4 (to be started last)

The DGU designated with start priority no. 1 is indicated by:

• a green "1ST START PRIORITY" LED

5.6.3 Determination of the stop priority

The Master DGU continuously designates each generator set with a PMS stop priority
number according to the programmed priority sequence.

A priority sequence 2 - 3 - 1 - 4 in the display designates:

• DGU no. 4 with stop priority no. 1 (to be stopped first)
• DGU no. 1 with stop priority no. 2
• DGU no. 3 with stop priority no. 3
• DGU no. 2 with stop priority no. 4

5.6.4 "1st PRIOR" push-button

The operator is able to designate the highest start priority to any generator set via the
corresponding CP by pressing the:

• "1st PRIOR" push-button

The example below shows how the start priority changes if the operator presses the "1st
PRIOR" push-button at the CP corresponding to DGU no. 4:

The start priority sequence before as read-out on the CP:

86
2-3-1-4 meaning:
• DGU no. 2 is designated with start priority no. 1 (to be started first)
• DGU no. 3 is designated with start priority no. 2
• DGU no. 1 is designated with start priority no. 3
• DGU no. 4 is designated with start priority no. 4 (to be started last)

Then the push-button "1st PRIOR" on the CP corresponding to DGU no. 4 is pressed!

The start priority sequence after as read-out on the CP:

4-2-3-1 meaning:
• DGU no. 4 is designated with start priority no. 1 (to be started first)
• DGU no. 2 is designated with start priority no. 2
• DGU no. 3 is designated with start priority no. 3
• DGU no. 1 is designated with start priority no. 4 (to be started last)

The load depending start/stop function will subsequently re-arrange the running generator
sets according to the new start priority.

5.6.5 Automatic designation of 1st start priority

This function ensures the operating hours (running hours) are equally distributed at all
generator sets in the power plant.

The total accumulated running hours for each generator set is counted and stored by the
corresponding DGU in a register "TOTAL RUN HOURS".

The example below shows the operating principles of the automatic designation of 1st
priority.

The start priority before the automatic designation function is carried out (2 - 3 - 1 - 4):

• DGU no. 2 is designated with start priority no. 1; "TOTAL RUN HOURS" = 12550
• DGU no. 3 is designated with start priority no. 2; "TOTAL RUN HOURS" = 12520
• DGU no. 1 is designated with start priority no. 3; "TO TAL RUN HOURS" = 12500
• DGU no. 4 is designated with start priority no. 4; "TOTAL RUN HOURS" = 12560

The start priority sequence after the automatic designation function is carried out (1 - 2 - 3 -
4):

• DGU no. 1 is designated with start priority 00. 1; "TOTALRUN HOURS" = 12500
*)
• DGU no. 2 is designated with start priority no. 2; "TOTAL RUN HOURS" = 12550
• DGU no. 3 is designated with start priority no. 3; "TOTAL RUN HOURS" = 12520
• DGU no. 4 is designated with start priority no. 4; "TOTAL RUN HOURS" = 12560

*) DGU no. 1 have the smallest number of accumulated running hours.

87
5.7. Black-out function
The blackout function is active whenever one of the following plant modes are selected:
• SEMI-AUTO mode
• AUTO mode
• SECURED mode

The blackout function consists of two separate functions:

• a common detection of "dead busbar" status
• the black-out start sequence

An individual detection of "dead busbar" status is made by all DGUs in the system.

The blackout start sequence is initiated once the Master DGU receives the internal "dead
busbar" status from all DGUs in the DELOMATIC system.

5.7.1. Dead busbar detection

The individual "dead busbar" internal signal is transmitted when the following conditions
have been continuously registered by a DGU during the programmable delay.
• the largest measured busbar phase-phase voltage (UL-L) is below 20 % of nominal
value
• the corresponding generator breaker is in OFF position
• no short circuit alarm is active in the DGU *)

*) A short circuit alarm at any of the DGUs will block the entire blackout start sequence.
The operator must in such cases acknowledge the short circuit alarm(s) in order to enable
the blackout start sequence.

If one or several of the above mentioned initiating conditions disappear, the "dead busbar"
detection is immediately disabled.

A synchronisation-alarm is automatically acknowledged (reset) in case of an active "dead

busbar" status in the DGU. This allows the generator set in question to attempt to connect to
the busbar.

5.7.2. The blackout start sequence

If the Master DGU is unable to communicate with a DGU (indicated by a communication
alarm message) the signal from the defective DGU is not required in order to initiate the
blackout start sequence.

NOTE! Activation of the blackout start sequence is only possible, if at least one of the
DGUs selected to be in PMS control and "ready for PMS start".

Fig. 19 Operating principle of the black-out function

The blackout start sequence carries out the following step-by-step sequence:

a) A PMS start command (activates the automatic start sequence in the DGUs) is
transmitted to the DGUs with the highest and second highest start priority, which at
the same time are "ready for PMS start".
b) The DGU which first obtains normal running feedback and normal generator
voltage/ frequency will close the breaker immediately (after receiving an
acknowledge-signal from the Master DGU).

If this does not result in the closing of the generator breaker, the other black-out
started generator set will (after approx. 2 sec. delay) be requested to close this
breaker without synchronisation.

c) The second black-out started DGU initiates synchronisation of the generator breaker,
approx. 2 s, after satisfactory voltage and frequency have been detected at the
busbar.
d) If any of the two chosen generator sets fails during the start sequence, the PMS start
command is transferred to the next stand-by generator set as long as the blackout
situation is present.
e) When one generator set is successfully connected to the busbar, the black-out
function is considered to be completed. The DELOMATIC system switch back to
"normal" operation again.

89
5.8. Conditional connection of heavy consumers
The conditional connection of Heavy Consumers function is able to handle 3 heavy
consumers (HCs).

When requested by a heavy consumer, the function for conditional connection of heavy
consumers reserves the programmed max. power at the busbar and blocks engagement of the
heavy consumer until sufficient predicted available power is present at the busbar.
After achieving sufficient predicted available power, the heavy consumer is subsequently
blocked until the programmed delay runs out.

The heavy consumers (HC) are connected according to their priority.

This means, if two or more heavy consumers request for start acknowledgement at the same
time, the HC with the highest priority is handled first, subsequently HCs with lower priority
etc.

HC 1 is designated the highest priority e.g.; HC 1 is handled before HC 3, if they request for
start at the same time. If there are any preferential HCs, these must be connected to the
hardware interface for HC 1 in order to ensure 1st priority handling.

The DELOMATIC system carries out the following step-by-step sequence, in case of a HC
request for start acknowledgement:

a) The programmed "HC n MAX POWER" value is reserved at the busbar.

b) A PMS start command is transmitted to the next stand-by generator set if the
predicted available power is below the programmed "LOAD START LIMIT",

If the predicted available power at the busbar is below O kW, the timer "DELAY ACK. HC
n" is blocked until the stand-by generator set is connected and sufficient predicted available
power is present at the busbar.

The timer “DELAY ACK. HC n” starts running at this point if the predicted available
power at the busbar is above O kW.

c) When sufficient predicted available power is present at the busbar, the timer
"DELAY ACK. HC n" starts running.
d) The start acknowledge signal is transmitted to the HC in question, when the timer
“DELAY ACK. HC n” runs out and sufficient available power still is measured at
the busbar.

90
6. Generator set control
Generator set control is handled by the DGUs according to a number of automatic
sequences.

The automatic sequences form jointly a complete cycle of operation for a generator set.

The Master DGU is able to initiate a complete cycle of operation for a generator set by
means of the PMS start command and the PMS stop command.

A DGU “ready for PMS start" will respond to the PMS start command by carrying out:

• the automatic start sequence

• the automatic GB ON sequence.

All generator sets in operation which are "ready for PMS stop" respond to the PMS stop
command by carrying out:

• the automatic GB OFF sequence

• the automatic stop sequence.

During an active SEMI-AUTO plant mode, the initiation of the automatic sequences is
carried out step-by-step (sequence by sequence) according to the operator commands via the
push-buttons at the CP(s).

Fig. 20 The automatic sequences contained in the cycle of operation for a generator set
All the above mentioned automatic sequences are controlled according to a number of
programmable set-points and timers - this enables the operator to adjust the automatic
operation of the generator set.
91
6.1. DGU operational modes for the generator set
Each generator set is controlled according to the selected DGU operational mode for the
controlling DGU.

Each generator set may be selected to be under either:

• Switchboard (SWBD) control

or
• Power management system (PMS) control

Switchboard control (DGU operational mode)

Generator sets under switchboard control (SWBD control) are only to be operated manually.
A generator set under SWBD control is excluded from all automatic PMS functions.

SWBD control is strictly local; all other generator sets operating under selected PMS control
will not be affected.

The synchronising unit in the SCM-1 module turns into SWBD control, when SWBD
control is selected on the DGU.

SWBD control enables manual control of the speed governor via the synchronising unit in
the SCM-1 module. The speed governor may be manually decreased and increased by
means of two binary inputs.

All supervision and protective functions regarding the generator set are still active for
generator set(s) under SWBD control e.g.:
• generator protection
• busbar supervision

PMS control (DGU operational mode)

Generator sets under PMS control are automatically controlled by the DELOMATIC system
according to the selected plant mode.

6.1.1. Automatic start sequence

The automatic start sequence starts the corresponding auxiliary engine and detects if the start
is completed successfully. A successfully completed start sequence initiates the GB ON
sequence.

The automatic start sequence is carried out when a DGU receives a PMS start command.
The PMS start command may e.g. be generated by the load depending on start/stop or by the
blackout function.
An operator dependent initiation (push-button) of the automatic start sequence may take
place in SEMI-AUTO mode (this will not initiate the GB ON sequence).

The start sequence is initiated when the DGU receives a PMS start command.

92
Each DGU in the DELOMATIC system is able to carry out the automatic start sequence,
which includes:
• continuous supervision of "ready for PMS start" status
• programmable time for the "START PREPARE" output
• programmable ON time for the “START” output
• programmable OFF time for the “START” output
• programmable activation of the stop output during OFF time
• programmable number of start attempts
• detection of start failure
• supervision of generator voltage and frequency during idle run
• transfer of the PMS start command to the next stand-by generator set in case of:
- start failure
- generator voltage or frequency failure

6.1.2. Automatic GB ON sequence

The GB ON sequence is automatically initiated (except during SEMI-AUTO mode) when
the automatic start sequence has been successfully completed.

The automatic GB ON sequence includes:

• detection of "ready for PMS synchronisation" status for the generator set
• programmable dynamical synchronisation
• generator breaker ON control
• transfer of the PMS start command to the next stand-by generator set in case of:
- a failed synchronisation
- a generator breaker ON failure

When the GB ON sequence is initiated it is indicated at the CP corresponding the DGU by:
• a yellow "GB ON" LED

6.1.3. Automatic GB OFF sequence

The GB OFF sequence is initiated when the DGU receives a PMS stop command from the
Master DGU (or a SEMI-AUTO initiated GB OFF) and the PMS stop command is only
accepted by the DGU if the generator set is "ready for PMS stop".

The GB OFF sequence deloads the generator set and will finally open the generator breaker.

93
6.1.4. Automatic stop sequence
The automatic stop sequence is carried out when the DGU has successfully completed the
GB OFF sequence.
The stop sequence is automatically initiated when the GB OFF sequence has been
completed.

The DGU in the DELOMATIG system is able to carry out the automatic stop sequence,
which includes:

• Automatic stop sequence incl.:

programmable cooling down time

"STOP" output with programmable extended ON time
• Semi-auto stop of engine incl.:

programmable cooling down time

"STOP" output with programmable extended ON time

94
7. Generator set supervision and protection
The DGU in the DELOMATIC system is able to handle local supervision and protection of
the corresponding generator set. Each DGU is implemented with the protective and
supervision functions.

NOTE! All local supervision and protective functions are also active during SWBD control.

7.1. Internal system supervision

The DGUs in the DELOMATIC system are implemented with an extensive number of
internal system supervision functions for supervision of their ability to carry out safe and
correct operation.

Each DGU continuously carries out the following system supervision functions:
• CP-1 supervision of the ARC-network
• CM-2 supervision of ARC-network and internal communication
• supervision of the generator breaker position feedback signals
• supervision of I/0 configuration (hardware)
• power supply supervision
• supervision of the multi-transducer unit in SCM modules
• cable supervision

7.2. Engine supervision

Engine supervision is handled by the DELOMATIC system according to the status on a
number of alarm inputs.

Each DGU in the DELOMATIC system is able to carry out the following engine supervision
functions:
• tacho feedback
• 6 user programmable alarms

The engine supervision functions are disabled when the engine is not running (stand-by).
Disabling of the engine supervision means that no alarms are generated by the supervision
functions.

The engine supervision functions are furthermore disabled during the automatic start
sequence until the auxiliary engine has obtained running status.

Each DGU is implemented with the following hardware interface, which is used in
coherence with the engine supervision functions.

95
7.3. Busbar supervision and protection
The DELOMATIC busbar supervision and protective functions are activated whenever a
generator set is connected to the busbar.

Busbar supervision is also activated at the Master DGU when a shore connection is
supplying the busbar (only if shore connection is present).

Each DGU carries out busbar supervision and protection according to individual
programmable set points and delays.

This means the DGUs may be programmed differently, but it is highly recommended to
program the busbar supervision functions with set points and delays common for the entire
DELOMATIC system.

Each DGU implements the following busbar supervision (warning) and protective (trip of
GB) functions:
• 2 level undervoltage, UBB<
• 2 level overvoltage, UBB>
• 2 level underfrequency, fBB <
• 2 level overfrequency, fBB >

7.4. Generator protection

The DELOMATIC generator set protection is separated into two parts:
• supervision of the generator during an idle run (the breaker is open)
• a set of protective functions which are active when the breaker is closed

The following generator supervision and protective functions are implemented in each DGU
in the DELOMATIC system:
• supervision of generator voltage and frequency during idle run
• protection against overcurrent; I > (2 steps; slow and fast)
• protection against reverse power; -P>
• protection against overload; P > (2 steps; high load and overload)

Each DGU carries out the generator protection according to individual programmable set
points and delays.

This means that the protective functions in the DGUs may be programmed differently
according to different characteristic values.

96
7.5. Trip of non essential load groups

The trip of Non Essential Load (NEL) groups is carried out in order to protect the busbar
against an imminent black-out situation due to either a high load on a generator set or a low
busbar frequency.

The trip of NEL groups function is implemented in each DGU. This means each DGU
executes the trip of NEL groups according to individual settings. But it is highly
recommended to program all DGUs with identical settings in order to obtain a uniform
operation.

Each DGU is able to trip two NEL groups due to:

• the measured load of the generator set

• the measured frequency at the busbar

The load groups are tripped as two individually load groups. Thus, the trip of load group no.
1 has no direct influence on the trip of load group no. 2. Only the measurement of either the
busbar frequency or the load on the generator set is able to trip the load groups.

Trip of NEL groups due to high load

Trip of the NEL groups due to the load of a running generator set will reduce the load on the
busbar and thus reduce the load percentage on the running generator set. This may prevent a
possible black-out at the busbar caused by an overload on the running generator sets.

NOTE ! Furthermore, both steps of NEL groups are tripped at the same time by the DGU if
the corresponding generator breaker is tripped.

99
 2. Set auxiliary engine cooling water preheater to position On

Note: To avoid shock effects owing to large temperature fluctuations just after the start,
it is recommended:

a) to preheat the engine, cooling water of at least 60o C should be circulated through the
frame and cylinder head for at least 2 hours before start.

- either by means of cooling water from engines which are running or by means of a
built-in preheater (if installed).

or

b) when starting without preheated cooling water, the engine must only be started on
DO (Diesel Oil).

The engine should not be run up to more than 50% load to begin with, and the increase
to 100 % should take place gradually over 5 to 10 minutes.

2. Switch on the generator on the bars by pressing the Gen. breaker ON push-button
in the generator’s field.

100
Attention:
The switching of the generator on the bars is confirmed by green control lights in the
generator field and the synchronisation block. In the synchronisation block, the frequency
indicator should indicate 60 Hz.

The generator’s synchronisation procedure

voltage indicator in the generator’s field should display around 440 V/
2. Switch the generator control mode switch to SWBD control.
3. Select the generator for manual synchronisation by using control switch:
• Manu Synchro of G1 – synchronisation of generator 1
• Manu Synchro of G2 – synchronisation of generator 2
• Manu Synchro of G3 – synchronisation of generator 3

Attention:
After selecting the manual method, the lamps SYNCHRO WHEN DARK will switch on
and off with a frequency depending on the difference between the frequencies of the
generator on the bars and the generator synchronised. Also the SYNCHROSCOPE will
indicate by the rotating LED the differences in their frequencies. If the LED rotates on the
right, the frequency is too fast / TOO FAST /, on the left - too slow / TOO SLOW /. The
adjustment of the appropriate frequency of the synchronised generator is realized by
Governor/Regler switch.

4. A synchronised generator can be switched on the bars with Gen. breaker ON push-
button, in their generator’s field, in the case the synchronisation lamps ”dark” are
completely extinguished and the LED in the synchroscope is switched on in the
position marked with an arrow.
5. After synchronisation, take over power load by using Governor/Regler switch.

Attention:
After an unsuccessful attempt of manual synchronisation both the generators will turn off of
the bars / BLACK - OUT / and the whole procedure of turning on and synchronisation will
have to be repeated from the beginning /i.e. from the moment the first generator was
started/.

3. Set prelubricating pump mode switch to position PMS /the pumps will start and stop
automatically according to the state of the engine/.
4. Press the START button on generator Control Panel CP-n /engine will start
automatically/

The generator’s synchronisation procedure

1. Press the GB ON button on generator Control Panel CP-n /generator will
synchronise automatically/.

The unloading and switching off the generator procedure

1. Press the GB OFF button on generator Control Panel CP-n /generator will unload
and switch off automatically/.

Stopping the engine

1. Press the STOP button on generator Control Panel CP-n /generator will unload and
switch off automatically/.

AUTOMATIC and SECURED MODE

1. Set PMS mode switch to position Auto or Secured.

During those full-automatic modes, the automatic control is carried out by all generator
sets, which are selected to be under PMS control.

The DELOMATIC system carries out automatic frequency and load control during the
AUTOMATIC plant mode.

Load depending start and stop of the generator set is carried out according to the actual
power demand at the busbar with respect to the programmed start/stop priority and the
programmed limits for start and stop.

If the DELOMATIC system detects a blackout situation at the busbar, a conditional blackout
start of two generator sets is carried out.

 COMPRESSED AIR SYSTEM SIMULATOR

1. Introduction

The educational program COMPRESSED AIR SYSTEM SIMULATOR is intended for

teaching the basic principles of how to operate a typical compressed air system.
The program is based on the compressor type HV2/200 (main air system), LL2/105 (control
air system), HL2/77 (emergency air system) produced by Sperre Industri A/S.

The program consists of the following parts:

• Control Panel
• Main Air System
• Control Air System

2. Operating procedures

The compressors may be operated manually (“MAN - AUTO” switch in position “MAN” –
manual operation) or automatically (“MAN - AUTO” switch in position “AUTO” –
automatic operation).
In manual operation compressor is controlled by the operator. Start and stop function
depends on “MAN - AUTO” switch position : 0 – stop, MAN – running.
In automatic operation compressor is controlled by the pressure switch:
a) first priority – start 2.5 MPa , stop 3 MPa
b) second priority – start 2.3 MPA, stop 3 MPa

Usually compressors may be controlled locally from local control panel or remotely, from
the control room. Remote control of compressors is not implemented in the simulator.

2.1. Preparing Main Air System

1. Open valves from fresh water cooling system to air compressors nr 1 and nr 2.
2. Open valves from compressors to main and auxiliary air receivers.
3. Switch on “Main switch”.
4. Set main air compressor no. 1 “PRIORITY” switch to position “1”.
106
 5. Set main air compressor no. 2 “PRIORITY” switch to position “2”.
6. Set main air compressor no. 1 “LOCAL - REMOTE” switch to position
“LOCAL”.
7. Set main air compressor no. 2 “LOCAL - REMOTE” switch to position
“LOCAL”.
8. Set main air compressor no. 1 “MAN - AUTO” switch to position “AUTO”.
9. Set main air compressor no. 2 “MAN - AUTO” switch to position “AUTO”.
10. Drain all air receivers.
11. Open valves to Main Engine, Auxiliary Engines and other receivers.

2.2. Preparing Control Air System

1. Open valves from control air compressor to control air receiver.

2. Set on “Main switch”.
3. Set control air compressor “MAN - AUTO” switch to position “AUTO”.
4. Drain control air receiver.
5. Open valves to Main Engine, Auxiliary Engines and other receivers through air
dryer.

2.3. Emergency operation

In emergency operation (no electric power and empty air receivers) it is possible to use emergency compressor
which is powered by emergency generator to fill auxiliary air receiver.

1. Open valves from emergency air compressor to auxiliary air receiver.

2. Switch on “Main switch”.
3. Set emergency air compressor “MAN - AUTO” switch to position “AUTO” .
4. Drain auxiliary air receiver.
5. Open valves to Auxiliary Engines.
