 2.4 Safety chain
The safety chain is equipped with two tested safety combinations:
• Machine EMERGENCY STOP safety chain (e.g. STL, centralized emergency off from PLC etc.)
• Manual EMERGENCY STOP safety chain (e.g. EMERGENCY STOP on the genset cabinet, building EMER-
GENCY STOP etc.)
The corresponding drives (e.g. gas valves etc.) are deactivated when one of the safety chains is triggered. A
manual EMERGENCY STOP deactivates all drives.
TIM-ID: 0000061923 - 002

MS60024/05E 2019-03 | General | 9

 2.5 CPU
The PLC's CPU is monitored by a watchdog. When this responds, all the PLC outputs are deactivated under
defined conditions and the safety chain is triggered.
The CPU can only be reset by means of a cold restart (switch miniature circuit breaker off/on). If the fault
occurs again, contact the Service department.

 2.6 Selectivity of protective devices
The selectivity of the protective devices (fuses, circuit breakers etc.) is configured in the switchgear for the
short-circuit current in island operation or for mains parallel operation with the grid.
In island operation, however, only the lesser short-circuit currents are available to the switched-in genera-
tors, and the selectivity of the protective devices is restricted.
The customer must ensure that in this operating state the selectivity of the protective devices in the consum-
er switchgear is guaranteed.

 5 Operating Modes
5.1 Manual operating mode
In this operating mode, the genset is started on a start request (all start conditions must be met) and runs up
to idle speed. The genset then remains in idle speed (MMC400: maximum 2 h / MMC4000: maximum 1 h)
until the synchronization delay is introduced or a stop is activated.
In the case of synchronization operation being initiated and completed successfully, a setpoint of approx.
10 % is assigned to the power controller. Now the power can be changed manually.
TIM-ID: 0000061935 - 001

MS60024/05E 2019-03 | Operating Modes | 21

 5.2 Automatic operating mode
In this operating mode, the genset starts following a start request and synchronizes with the grid automati-
cally. Depending on the selected mode of operation (fixed value control, variable value control, heat-control-
led etc.), the current setpoint is transferred to the power controller (MMC400) or ADEC governor
(MMC4000) and approached.
• In automatic mode, various auxiliary features are integrated in the starting sequence. Dependent upon
which function is active (e.g. timer, grid feed-in control, CH4 content etc.), the start enable for the relevant
feature is taken into account when a start request is active. If there is a problem, a summary alarm is
output.
• If a drive or a controller (e.g. engine coolant pump etc.) is in manual mode when a start is initiated, man-
ual mode is reset. This ensures that no undefined switching states occur in automatic mode (e.g. the gen-
set would overheat if the engine coolant pump was switched off).

TIM-ID: 0000061931 - 001

22 | Operating Modes | MS60024/05E 2019-03

 5.3 Grid backup mode
In isolated operation the power is determined by whichever consumers are switched in.
Speed control simply has to readjust the speed setpoint after load changes. This setpoint is specified via a
frequency controller.
On systems with multiple engines, gensets working in parallel must not be allowed to run with differing per-
centage loads. An effective load distribution system is also provided for this purpose in addition to the fre-
quency controller.

24 | Operating Modes | MS60024/05E 2019-03

 5.5 Switching the grid on
Synchronous generators may only be connected to an existing grid if their voltage, frequency and phase an-
gle are identical. To meet the required conditions, a synchronizer is required. The synchronizer uses the
speed controller to influence the frequency of the generator up to the point of switching-in. The synchronizer
uses the voltage regulator to influence the voltage of the generator up to the point of switching-in.

 6 Floating Contacts
6.1 Floating contacts – General
The control system outputs various floating contacts by default. These contacts can be used to activate
drives or to query the status of the system.
Specific projects may feature more of these messages.

TIM-ID: 0000061940 - 001

26 | Floating Contacts | MS60024/05E 2019-03

 6.2 Floating contacts – MIP
Start request for auxiliary drives
The contact is switched on during a start sequence. When the engine meets the operating conditions, the
run-on timer is activated. When the genset is stopped again, the run-on timer for the auxiliary drives switches
in. This cools the engine. The contact is not switched off again until the run-on time has expired.
• The auxiliary drives are always switched off in the event of a "manual EMERGENCY STOP" (safety chain
has triggered).
• The auxiliary drives are also activated once for a run-on cycle if a PT1000 / PT100 temperature (e.g. en-
gine coolant temperature, intake air temperature, etc.) has been exceeded. The aim is to remove any heat
that might have become trapped and returning the engine to readiness for starting.

Open back-up switch

The contact closes if the fault message "088 - generator circuit breaker will not open -- trailing mode active"
is pending. Optionally, the contact can be activated with fault message "087 - generator circuit breaker will
not open."

Manual EMERGENCY STOP to outside

The contact opens if the safety chain of the manual EMERGENCY STOP is triggered.

 6.3 Floating contacts – MMC
Ready-to-operate for external selection
This contact remains closed if the following criteria are met:
• Key switch set to enable genset
• Key switch set to remote
• Key switch set to automatic
• No stop or EMERGENCY STOP pending
• Engine stationary and no start command pending

Group fault
The contact opens if a stop or an EMERGENCY STOP is pending. Only notifications activated accordingly in
the fault message parameters are effective.

Engine running
The contact is closed as soon as the engine reaches a speed in excess of 1000 rpm (MMC4000) or
1400 rpm (MMC400).

Manual EMERGENCY STOP to outside

If the safety chain of the manual EMERGENCY STOP is triggered, the contact opens.

This switch is used to halt genset operation. If the machine is at a standstill, start-up of the genset is pre-
vented. If the machine is running, a controlled shutdown is activated.

Designation Type of switch Position Action

Local / Remote control Key switch 0 Local control
1 Remote control
This switch is used to set the control mode. If the plant is to be controlled directly at the genset, the switch
must be set to “Local”. This will then allow any target value to be altered at the IPC.
Also, the “Start/Stop” switch at the control cabinet will be active. If the plant is to be controlled remotely
(remote starting/stopping, remote target value control, control via interface), the switch must be set to
“Remote”.
Mixed control is not possible. For example, it is not possible to have the start request via hardware signals
and the power specification via the interface. In this case, both signals must be specified via the interface.

Designation Type of switch Position Action

Manual / Automatic Key switch 0 Manual mode
mode 1 Automatic mode
In automatic mode, the start process is initiated following a start command, the genset is synchronized
with the grid automatically and the power is raised (ramped up) to the set value. All regulating tasks are
performed automatically.
In manual mode, the start process is initiated following a start command. The genset starts up and remains
in a ready-to-synchronize state once the nominal speed is reached. During this phase, the speed can be
adjusted manually (higher/lower pulses via buttons on the display). Another button (on the display) can be
used to initiate the synchronization process. After successful synchronization with the grid, a power of 10%
is specified. The target value has to be adjusted manually. All regulating tasks are performed automatically.
Requirement for manual mode: “Local control” setting

 8.4 Load stage control (optional)
Load shedding control can be activated in grid backup mode.
Up to 8 repair sizes can be activated with the Series 400 or 24 repair sizes with the Series 4000. If the grid
backup is initiated, the control system issues the "Load shedding" command.
Only when registered that the load shedding has been carried out successfully ("Load shedding" LED) does
the grid backup continue and the GCB is closed.
As soon as the GCB signals that it is closed, the stages are switched back in at staggered intervals. The re-
pair sizes continue to be switched in until the last repair size has been activated or an overload (optional
evaluation) occurs.
Staggered switching-in of load stages enables the engine to optimize load regulation.
• All load stages are switched back in at standstill or when the grid switch is closed.
• "Load shedding successful" checkback signal:
All checkback signals for the individual stages are connected in series.
• Stages for which a delay time of "0" has been entered are not shed (even in the event of an overload).
The load stage contactors have to be controlled so that the contactors switch in when the coupling relay
drops out.
This ensures that power will continue to be supplied to the consumers, even in the event of the control
system being affected by a failure or repair work.

With overload monitoring:

If the "Overload monitoring" option has been activated, power values can be assigned to the individual
stages.
If the current genset power actual value is > (power value (of the repair size currently switched in) + overload
limit value), a time delay expires.
At the end of this time a fault message is output (overload in grid backup mode) and a repair size is shed.
This process is repeated until the load returns to a value that does not reach the limit value, or the last stage
that can be shed has been shed. The stages are not switched back in until the fault message has been ac-
knowledged if the load still exceeds the limit value.
If the extent of the load connected is so great that the genset shuts down due to underfrequency, this moni-
toring mechanism will not function.
Monitoring also ensures that the next stage is not switched if the load to be expected exceeds the permissi-
ble load for grid backup mode. If this is the case, the fault message is also output and the next stage is not
switched in.
Series Delay Unit Meaning
Series 1–8 s The corresponding load stage is not switched in until the time interval
400 has expired. The next interval then runs, and a second stage is switch-
Series 1–24 s ed in.
4000 Special feature: Stages with a delay time of 0 s are not shed. Howev-
er, these steps may only be defined at the start (e.g. step 1 and
step 2). As soon as a delay time has been defined for a step (e.g.
TIM-ID: 0000061950 - 001

step 3), a delay time of 0 s cannot be entered for any subsequent step
(e.g. step 4).
Example for 4 load stages:
Correct: Stage 1 = 0 s, stage 2 = 0 s, stage 3 = 10 s, stage 4 = 10 s
Incorrect: Stage 1 = 0 s, stage 2 = 0 s, stage 3 = 10 s, stage 4 = 0 s
In the incorrect example, all delay times would then be set to the de-
fault value of 2 seconds.
This is done automatically by the system.

MS60024/05E 2019-03 | Operation and Visualization - Main Menu | 45

 Optional parameters for overload monitoring:
Parameter Unit Meaning
Power value % A maximum permissible power value is assigned to each stage. The power to
be expected should not exceed this value. If the values entered exceed 100 %,
a default setting is applied (30/30/30). This is done automatically by the sys-
tem.
Overload limit % This value is added to the total power value (sum of all active stages). If the
current power actual value exceeds the limit value calculated in this way, once
the overload delay has expired, a fault message is sent and the step is shed.
Overload delay % If the calculated overload limit is exceeded, this time interval expires. Once the
interval has expired, the "Overload in grid backup" fault message is output and
the stages are shed as described above.

1 Voltage controller Voltage regulator

2 Power factor controller Power factor controller

Variable adjustment of the voltage and the power factor is possible through the MMC. The generator voltage
regulator controls the voltage or the power factor through an analog setpoint specification of the MMC. The
setpoints for the regulator and the corresponding control parameters can be set via the visualization.
When the genset has started and a set generator voltage is exceeded, the voltage regulator is active. The
voltage is now adjusted to a specified setpoint. During synchronization, automatic voltage adjustment to the
grid to be synchronized is carried out. When the genset is in sync with the grid, the voltage is fed to the grid.
Thus a power factor can be controlled by the power factor controller.
In grid backup/isolated operation, the voltage is controlled to a specified setpoint.

Parameter Unit Meaning
Start ramp mbar/s When the gas compressor is activated, the start setpoint of 0 mbar is increased
to the actual setpoint via this ramp.
Setpoint mbar This parameter corresponds to the setpoint for the control.
Kp – Proportional component of the controller. Depending on the mbar deviation, the
manipulated variable is increased or decreased by this factor (e.g. system devia-
tion +5 mbar, KP = 6: The proportional component of the manipulated variable is
30%).
Ki – Integral component of the controller. If the system deviation persists, whenever
the follow-up time (Tn) expires, the Ki value is added to the P component and
output. A high Ki value may result in oscillation of the setpoint for the frequency
converter.
Tn s The follow-up time is used to calculate the I component. The output value of the
I controller is then added to the output value of the P controller at these inter-
vals. A follow-up time that is too low may result in oscillation of the setpoint for
the frequency converter.

 8.18 Fault messages
This interface provides an overview of pending fault messages.
It is also possible to switch to the Alarm Logger. The Logger records all fault and operating messages over a
prolonged period with time stamping. This also makes it easier to analyze faults.

Functionality:
The window opens automatically when a new fault message appears.
If a new fault message arrives, the corresponding collective message flashes in the menu bar (e.g. N flashes
red: there is a new EMERGENCY STOP). The fault messages can be acknowledged with the Reset button.
When the fault message is no longer pending, the text disappears.
• Stopped fault messages appear in red
• Non-stopped fault messages appear in yellow
Acknowledged fault messages are displayed in the "Quit" column by the "x" symbol.
The fault message window can be exited with the Home button.
The fault message window is then only opened again if a new fault message occurs or is selected via the N,
S, A buttons.
• The fault messages are included in a separate list.
• In some cases, there are system-specific messages that also appear there.
• The list is always compiled based on the project.
For the fault message overview, there are two important differences in the faults:
1. Self-acknowledging faults:
These faults are automatically reset after remedying the cause and deleted from the fault message over-
view.
2. Non-self-acknowledging faults:
These faults can only be reset by the user after remedying the cause by actuation of the Reset button
(on the control cabinet or on the fault message page).
• Fault messages which trigger the EMERGENCY STOP chain can only be acknowledged using the hardware
reset (button on the MMC cabinet).
The "Source" column is only of interest for systems with several gensets and central fault history as the gen-
set number is played back in order to decide which genset has the fault.
If the number of faults is so large that not all faults can be displayed in the table, the arrow buttons on the
right of the table can be used for scrolling up and down.
• Previously cleared faults can also be retrieved using the Alarm Logger. TIM-ID: 0000062034 - 001

switch is off etc.).
The image structure is identical with that of the fault messages. Each active status message appears in
green.

played. The default setting is both.
TIM-ID: 0000062036 - 003

Alarm number:
If there is a search for the occurrence of a specific alarm, the search for an alarm number can be activated
using the "No. search". The searched-for number must also be entered in the box underneath. Up to 4 num-
bers can be selected. The numbers can be reset using the "Reset" button.

Days:
By default the database always searches for events of the previous day. The database can also be set to
search for older events in the upper box. The largest value is 31 days.

MS60024/05E 2019-03 | Operation and Visualization - Main Menu | 67

 The value of the second box must always be 1. If there is a search for events with a specific period, e.g. 10 to
20 days ago, the value must also be changed in the second box. The value of the second box must always be
greater than the value of the first box. The value of "31" cannot be exceeded.

Save button:
This button can be used to copy the current database (AlarmloggerAktuell.mbd) into the "D:\MTU\FileShar-

 Primary balancing power (optional)
When this operating mode is active, the power setpoint is determined based on the grid frequency.
Positive and negative power must always be offered. The working point is the power point at which a grid
frequency of 50 Hz is run over the complete additional period.
In case of underfrequency, power is increased as a function of the frequency and the sold primary balancing
power; in case of overfrequency, power is reduced as a function of the frequency and the sold primary bal-
ancing power.

Power reduction:
This displays whether a power reduction is active or not. The reduction can be triggered by various factors:
• Engine
The power reduction is carried out by the ADEC governor. A corresponding reduction is signaled.
• Gas exchange (optional)
The power is reduced to a configurable value during the gas exchange. This value can even remain below
the genset's minimum load.
• Generator (optional)
Power reduction by the generator if the required electric power depending on the generator voltage (cor-
responds to the grid voltage in mains parallel operation), the power factor and the cooling air temperature
can no longer be made available to the fullest extent.
• Mixed coolant temperature inlet (limit value 1) (optional)
If limit value 1 (set with the fault messages) is exceeded, the power is reduced from 100% to minimum
load (50% by default) in a linear fashion along a ramp between limit value 1 and limit value 2. If, however,
the second limit value is still exceeded, the genset shuts down.
• Mixed coolant temperature outlet (limit value 1) (optional)
Reaction as for mixed cooling water temperature inlet.

ny is signaled here.
• Dew point lower limit violation:
Power reduction if the temperature at the mixture coolant inlet is below the setpoint. A limit value curve
as a function of the dew point is stored.

• Actuator with open/close pulses (with end positions)
A Manual mode can be initiated for both actuators. The Manual mode is reset again each time the genset is
restarted.

80 | Operation and Visualization - Additional Functions | MS60024/05E 2019-03

 Special feature:
Actuator with open/close pulses and end positions:
• A reference travel is initiated after each expiry of the run-on time.
• This determines the run time of the valve and the current position of the regulating valve can always be
calculated via the pulse/pause ratio.
• The reference travel can also be activated manually during a standstill using the "Reference travel" button.
• An initiated reference travel can no longer be canceled.

The Kp is separately adjustable for normal operation and the warm-up time.
Ki – Integral component of the governor. If the system deviation persists, each time the
follow-up time (Tn) expires, the Ki value is added to the P component and output. A
higher Ki value may result in oscillation of the setpoint for the regulating valve.

4 Control variable Correcting variable
5 Manual Manual

The controller comprises two separate PI controllers which operate in parallel. Each PI controller regulates
its own correcting variable; the larger value of the correcting variable is transferred to the regulating valve as
an output value.
The regulating valve can be set from closed (0%) to open (100%).
Example: If the first PI controller regulates to a correcting variable of 80% and the second PI controller to a
correcting variable of 72%, 80% is transferred to the regulating valve as an output value.
TIM-ID: 0000062058 - 003

If both PI controllers have a correcting variable of >10%, the controller with the smaller correcting variable is
set to the correcting variable of the other controller. An excessive step change in the correcting variable is
prevented when switching over the controllers.
Example: The first PI controller regulates to a correcting variable of 80%, the second PI controller regulates
to a correcting variable of 72%. The second PI controller reduces its correcting variable from 72% to 69.9%
due to the setpoint/actual value deviation. The correcting variable deviation is now greater than 10%, the
correcting variable of the second PI controller is then set to the correcting variable of the first PI controller,
i.e. 80%.

The Kp is separately adjustable for normal operation and the warm-up time.
Ki – Integral component of the governor. If the system deviation persists, each time the
follow-up time (Tn) expires, the Ki value is added to the P component and output.
A higher Ki value may result in oscillation of the setpoint for the regulating valve.

The number of stages present is determined via a module parameter.

A maximum of 8 stages are available. One stage represents only one switching threshold. This can also mean
that, with two stages, a blower is configured with star/delta connection.
TIM-ID: 0000062062 - 003

For Manual mode it is possible to switch between the individual stages with the arrow keys. The current sta-
tus (Manual/Start/Stop) is displayed for the selected stage (no.). When a stage is in operation, this is sig-
naled by a green LED.
It is also possible to operate each stage manually. Manual mode is indicated by an orange LED.
The function of each individual stage can be defined via the following four parameters.

In this variant, the emergency cooler blower is controlled via FC.

Up to 2 FCs can be used (0 to 100% / 0 to 10 V).
A PI controller which outputs the correcting variable (0 to 10 V) to the FC is used for this.
The correcting variable can also be set manually.

Transfer value % Can be switched on depending on the system.
The transfer value can be linked with another control loop contingent on the
project. If this control circuit is deactivated, this transfer value is taken over by
the control. This ensures a smooth switch-over.

General information
The room temperature is regulated to a defined setpoint using this function. Flap activation (supply air, ex-
haust air and circulating air) must be interconnected via the hardware so that all flaps can be brought to the
correct position with a control input (e.g. 0 to 10 V).

Switch-off °C If the temperature actual value falls below this limit value, the ambient air stage is
value deactivated when the off-delay time expires.
Off-delay s Off-delay for the ambient air stage

Optional: If a gas alarm occurs, all blower stages are compulsorily activated.

Activation of the room blower (can be set as required)

The blower can be enabled as required using the "Room blower enable" button.
The following combinations are possible:
• Enable even during a standstill of the system
The blowers are switched on (even with a stopped machine) after exceeding the limit value.
• Enable only when operating the system
The blowers are only enabled when the machine is running and the limit value exceeded
• Stage 1 immediately upon operation
This option can be selected for the two variants mentioned above. The first blower stage is then switched
on immediately when the engine starts (independent of the limit value).

Variant 2: Room blower via frequency converter

In this variant each of the room blowers (supply air and exhaust air) are controlled by an FC. To do so, a PI
controller is used which outputs the setpoint (0 to 10 V) to the FC. The correcting variable can also be set
manually.

 9.10 CH4 control (optional)
General
The CH4 control is divided into several areas:
• Start enabling for the engine based on the CH4 content (digital contact or limit value via analog actual-
value signal)
• Power limitation by means of the CH4 content (only works when an analog actual value signal is available).

NOTE
All functions are only active in automatic mode.

Start enable via digital contact

The genset is enabled or stopped by means of the CH4 content. A digital transmitter is read for this.
The following parameters are available:
Parameter Unit Meaning
Switch-on delay s If the contact is present, this time expires. Only after the time expires
and with the signal pending is the genset enabled.
Off-delay s If the contact is no longer pending, this time expires.

Start enable via analog signal (optional)

The genset is enabled or stopped by means of the CH4 content. To do so, an analog actual value signal is
read and compared with the limit value.
The following parameters are available:
Parameter Unit Meaning
With CH4 content on % If the actual value exceeds this limit, the on-time expires.
Switch-on delay s If the limit value is exceeded, this time expires. Only after the time has
expired and the limit value is exceeded is the genset enabled.
With CH4 content off % If the actual value falls below this limit, the off-time expires.
Off-delay s If the limit value is fallen below, this time expires. Only after the time
expires and the limit value is fallen below is the genset enabled.

The curve must be determined by the customer.

NOTE
The values can only be altered from a specific user level (service).
TIM-ID: 0000062065 - 002

Power limiting via analog signal (optional)

The power of the engine is limited by means of the CH4 content. To do so, an analog actual-value signal is
read in and compared with the limit values.
The following parameters are available:

MS60024/05E 2019-03 | Operation and Visualization - Additional Functions | 97

 Parameter Unit Meaning
At min. CH4 content % This CH4 value is assigned to the lowest power value.
Power at min. % If the CH4 value falls below the min. limit value, the power is limited to
this value.
The limit is calculated by a straight line between the minimum and maxi-
mum value.
At max. CH4 content. % This CH4 value is assigned to the highest power value.
Power at max. % If the CH4 value exceeds the max. limit value, the power is limited to this
value.
The limit is calculated by a straight line between the minimum and maxi-
mum value.

Start setpoint CH4 content

The engine start and engine operation up to 10% power are carried out in regard to the CH4 content via the
default from the MMC.
If the MMC receives a CH4 measurement signal via a sensor, the engine uses this transferred CH4 value up to
a power of 10%.
If the MMC does not receive a CH4 measurement signal via a sensor, the CH4 content is defined manually via
the MMC in a range from 45% to 65%.
Above an engine power of 10%, the ADEC governor basically calculates the current CH4 content automatical-
ly. The engine then also compensates for changing the CH4 contents independent of the CH4 measurement
signal.
Configurable parameters:
Parameter Unit Meaning
Start setpoint CH4 con- % The CH4 content can be changed in a range from 45% to 65%. The start
tent setpoint button must be actuated to do this. If the sensor for the CH4
measurement signal is not present or the sensor has a hardware fault,
the Start setpoint button is activated automatically

NOTE
The CH4 content start setpoint parameter is only used for engine start. The start enable
via CH4 content and power limiting are not affected by CH4 content functions. TIM-ID: 0000062065 - 002

 9.11 Gas tank (optional)
General information
The gas tank control system is divided into several areas:
• Gas flare
• Start enable of the engine by means of the fill level/gas pressure
(digital contact or limit value via analog actual value signal)
• Power limiting by means of the fill level/gas pressure
(digital contact or limit value via analog actual value signal)
NOTE
All functions are only active in automatic mode.

NOTE
The analysis is either carried out via an analog signal (standard) or via digital signals
(3 contacts).
A combination is not possible.
All parameters must be determined by the customer.

Gas tank flare activation (fill level/pressure): Enable via analog signal
The flare is enabled or stopped by means of the fill level/pressure. To do so, an analog actual value signal is
read and compared with the limit value.
The following parameters are available:

 9.12 Grid feed-in control (optional)
General information

Figure 26: Switch

1 Grid bar 3 Grid transfer power 5 Generator
2 Busbar 4 Generator power 6 Consumer power
There are three ways of regulating the grid transfer power:
• System draws power from the grid
• System feeds power into the grid
• Regulated to zero load at the grid transfer point (zero load control)
The actual value signal on the grid transfer point is a "±signal" (e.g. -1000 kW to +1000 kW).
The signal is assessed as follows:
• Generated power < consumed power
Signal is positive (+), system draws power from the grid.
• Generated power > consumed power
Signal is negative (-), system feeds power into the grid.
• Generated power = consumed power
Signal is zero, system feeds nothing into the grid and draws nothing from the grid
TIM-ID: 0000062067 - 001

The start enable of the genset can be set by means of the grid transfer power. The engine is only enabled if
the parameterizable switch-on threshold is exceeded. The same applies to the switch-off threshold.
The system can ideally be used in order not to have to count any peak currents, for example.
NOTE
All functions are only active in automatic mode.

MS60024/05E 2019-03 | Operation and Visualization - Additional Functions | 101

 NOTE
Care must be taken with the functions (grid feed-in control and start enable) that they
do not mutually eliminate each other (e.g. the grid feed-in control should regulate to a
value that is, however, already assessed as the deselection point of the system).

Status messages
Status messages:
• Active
When the grid feed-in control is activated is displayed here.
• Feed
This shows when the system is feeding into the grid.
• Reference
This shows when the system is drawing from the grid.
• Dead band
This shows if the system deviation is less than the dead band.
• Setpoint max
This shows if the calculated setpoint has reached the maximum permitted setpoint for the power control-
ler.
The maximum setpoint (%) is displayed in the power controller parameters. The setpoint is set in the mod-
ule parameters and cannot be changed.
• Setpoint min
This shows if the calculated setpoint has reached the minimum permitted setpoint for the power control-
ler.
The minimum setpoint (%) is displayed in the power controller parameters. The setpoint is set in the mod-
ule parameters and cannot be changed.
• Start enable
If the setpoint/actual value comparison is negative, the system is feeding into the grid.
If the setpoint/actual value comparison is positive, the system is drawing from the grid.

Parameters for grid feed-in control

Parameter Unit Meaning
Setpoint kW The power at the grid transfer point is regulated to this value. If this is a negative
value, the system should feed into the grid.
Dead band kW If the system deviation (xd) is below this value, the setpoint for the power control-
ler no longer changes. This stops any oscillation of the system.
Increment kW This value specifies by how many "kW" the setpoint for the power controller is
changed per second.
The setpoint for the power controller is only changed if the system deviation is
greater than the dead band. The increment value must be selected to be less than
the value of the dead band.
Pause time s This is the pause time between two changes of the setpoint for the power control-
ler.

Parameters for start enable

Parameter Unit Meaning
X1 kW Non-delayed selection. If the actual value exceeds this limit, the engine is enabled
immediately.
X2 kW Delayed selection. If the actual value exceeds this limit and is less than the non-
delayed switch-on value, the engine is enabled after a delay. The delay time is cal-
culated on a straight line between the non-delayed and delayed switch-on value.

102 | Operation and Visualization - Additional Functions | MS60024/05E 2019-03

 Parameter Unit Meaning
Y1 s Delay time for the selection. This time is calculated between the non-delayed and
delayed and delayed switch-on value via a straight line. The closer the current ac-
tual value comes to the non-delayed switch-on value, the shorter the delay time.
X3 kW Delayed deselection. If the actual value falls below this limit, the engine is dese-
lected after a delay. The delay time is calculated on a straight line between the
non-delayed and delayed switch-off value.
X4 kW Non-delayed deselection. If the actual value falls below this limit, the engine is de-
selected immediately.
Y2 s Delay time for the deselection. This time is calculated between the non-delayed
and delayed and delayed switch-off value via a straight line. The closer the cur-
rent actual value comes to the non-delayed switch-off value, the shorter the delay
time.

The limit value for the selection and deselection must always become smaller from left to right (on the X
axis). If this is not adhered to, a default value is activated.

 9.13 Exhaust/bypass flap control (optional)
General information
The exhaust flap is opened when the genset is started. It is necessary for systems with several gensets to
prevent the back flow of combustion air into the deselected gensets.
The task of the bypass flap is to guide the hot exhaust gas past the exhaust heat exchanger during low heat
consumption to prevent the heating water overheating.
The bypass mode can be activated by the parameterizable limit value or manually via the Select button. The
bypass mode can also be activated remotely via an optional input. Flap 2 is opened first and flap 1 closed
only after the "Open" limit switch activates.
All flaps can also be operated manually.

Parameters for bypass mode

Parameter Unit Meaning
Bypass mode limit °C If the limit value is exceeded, bypass flap 2 opens first and bypass flap 1
value then closes.
Hysteresis for by- °C If the hysteresis falls below the limit value, the bypass mode is deactivat-

 NOTE
All functions are only active in automatic mode.

Example with heating water return temperature as setpoint:

Measuring the heating water return temperature using separate sensor in the system.
Start enable (values correspond to the current image):
If the genset is stopped and the heating water return temperature (actual value) falls below 66 °C (X2 in the
image), the system waits 30 s (Y1 in the image) until the genset is selected. The further the temperature falls
(X1 direction), the faster the genset is selected.
Control (values correspond to the current image):
When the genset is running, the set power is determined by means of the heating water return temperature
in the PI controller. The current actual value of the temperature is also displayed. There is an attempt to reg-
ulate the heating water return temperature to the "setpoint" (70 °C in the example). As long as the heating
water value is less than the heating water setpoint, the genset power setpoint (power setpoint) is increased
in accordance with the control parameters (to maximum 100%). If the heating water actual value rises above
the heating water setpoint, the genset power setpoint is reduced again (to min. setpoint).
"Heat mode with limiting function" special feature:
In this operating mode, the calculated setpoint is still limited by the grid feed-in control. The setpoint is not
increased further, like the currently calculated setpoint of the grid feed-in control.
Shutdown (start enable is deactivated):
As soon as the heat controller registers "Setpoint min." and the "Hot water temperature > limit value 1" fault
message appears, the genset is deselected. Thus, as long a runtime as possible of the genset is achieved.

Parameters for power control

Parameter Unit Explanation
Specified value °C This parameter corresponds to the setpoint (heating water temperature) for
the control. After the start ramp expires, the controller regulates the heating
water temperature to this value via the genset power.
Start setpoint °C After the controller has been activated, the setpoint temperature is in-
creased via a start ramp.
The start ramp (for the temperature setpoint) is started from this value.
Warm-up time s During the warm-up time, the temperature setpoint is increased from the
start setpoint to the actual setpoint.
Only after this time expires is it regulated to the temperature value that was
entered for "Setpoint".
Kp – Proportional component of the controller. Per 1 °C deviation, the correcting
variable (genset power setpoint) is opened or closed by this factor (e.g. sys-
tem deviation +5 °C, Kp=6: The proportional component of the correcting
variable is 30%).
Ki – Integral component of the governor. If the system deviation persists, each
time the follow-up time (Tn) expires, the Ki value is added to the P compo-
nent and output. A higher Ki value may result in oscillation of the setpoint
for the genset power.
Tn s The follow-up time is used to calculate the I component. The output value of
the I controller is then added to the output value of the P controller at these
intervals. A follow-up time that is too low may result in oscillation of the set-
point for the genset power.
Setpoint min. % Corresponds to the minimum power at which the genset should operate.

 9.16 Outside temperature shift (optional)
General information
The outside temperature shift can be used for the heat mode (engine and boiler). The switching thresholds
for the enable are influenced by this function.
An offset (positive or negative) is calculated from the curve by means of the current outside temperature
which is then added to the switching thresholds. The shift can be adapted to the circumstances via 3 in-
clines. 4 parameter sets are needed for this.
The limit value for the X axis (outside temperature limit value) must always be greater from left to right.
The switching thresholds can also be shifted downward through lowering by an adjustable value (activated
via an optional input).
Parameter Unit Meaning
Offset °C All switching thresholds are shifted downward by this value.

 9.26 Load distributor parameters
Parameter Unit Meaning
Number of load distribu- – Number of gensets involved on the internal load distribution. The set-
tion gensets ting of the node number switch on the X20CPU is thus important:
Genset 1 needs node number 11, genset 2 needs node number 12
etc.
Nominal power kW Nominal power in isolated operation. This is normally set to 90% of
the grid parallel nominal power. The nominal power is required for
calculation of the utilization factor of the genset.
Tn s Follow-up time of the governor. The smaller the value, the faster the
governor.
Kp – Proportional component of the governor. The larger the value, the
faster the governor.
Dead band nominal rpm The calculation of the integral component of the effective load distri-
speed for activating Tn bution can be suspended with this parameter. For a 50 Hz installation
(=1500 rpm), only the integral component is calculated, if the current
engine speed lies between 1500 rpm ± of the set value. For a set val-
ue of 30 rpm, this would correspond to a speed range from
1470 to 1530 rpm. After load connections and load disconnections,
the speed governor is given time to settle before the integral compo-
nent of the actual effective load distribution is active. "Running away"
of the integral component, so-called overshoot or undershoot, can
thus be prevented.
Time for activating Tn if ms When the engine speed is back in the dead band, the set delay is
dead band is active started. When the delay has expired, the integral component is recal-
culated.
Loading the ramp rpm/s Parameters for the Ramp up function. The Ramp up function is need-
ed if the genset is connected a genset already in isolated operation.
The set speed preset of the MMC to the governor is increased linearly
to the actual setpoint linear by the set value (rpm/s).
Releasing the ramp rpm/s Parameters for the Ramp down function. The Ramp down function is
needed if a genset is deselected in isolated parallel operation (by de-
selecting the start request or controlled stop). The set speed preset
of the MMC to the governor is decreased linearly from the actual set-
point linear by the set value (rpm/s). The GCB opens at 1% generator
actual power.
Diesel setpoint ramp kW/s This parameter is normally required in grid backup mode via external
control engineering a diesel engine interface. In isolated parallel oper-
ation, the setpoint for actual power output in kW is preset by the ex-
ternal control engineering. The setpoint ramp indicates how fast (in
kW/s) the setpoint should approach the end value. The ramp is line-
ar.

The most important parameters for the frequency controller can be set here.
Parameter Unit Meaning
Synchronization: Kp – Proportional component of the frequency controller during
synchronization of the GCB or the mains circuit breaker.
The larger the value, the faster the governor.
Synchronization: Ki – Integral component of the frequency controller during syn-
chronization of the GCB or the mains circuit breaker. The
larger the value, the faster the governor.
Synchronization: Tn ms Run-on time of the frequency controller during synchroniza-
tion of the GCB or the mains circuit breaker. The smaller
the value, the faster the governor.
Isolated operation/idle: Kp – Proportional component of the frequency controller in iso-
lated operation or idle mode. The larger the value, the fast-
er the governor.
Isolated operation/idle: Ki – Integral component of the frequency controller in isolated
operation or idle mode. The larger the value, the faster the
governor.
Isolated operation/idle: Tn ms Run-on time of the frequency controller in isolated opera-
tion or idle mode. The smaller the value, the faster the gov-
ernor.
Max. difference frequency for syn- Hz The generator frequency is controlled to a certain extent via
chronization the busbar frequency/grid frequency.
The maximum difference frequency is set with this parame-
ter. Ultimately the spacing of the generator frequency to
the max. difference frequency can then be set using the
"Factor for generator frequency to max. difference frequen-
cy spacing" parameter.
Factor for generator frequency to – The generator frequency is controlled to a certain extent via
max. difference frequency spac- the busbar frequency/grid frequency.
ing. This factor determines the spacing of the generator fre-
quency to the max. difference frequency.

IPC
• Once data transfer to the USB stick is complete, the "Saved, OK" message appears. The switch can no
longer be pressed until a new image is present in the screenshot document file
• The USB stick can be removed again after backing up the data
Proceed as follows to move the interface protocol onto a USB storage medium:
• Insert a USB stick in a free USB slot
• The interface protocol must be created under "External communication" → Interface status → Pressure
button.
• An "MTU\InterfaceProtocol" folder is created on the USB stick if it does not yet exist.
TIM-ID: 0000062210 - 004

• When backing up the interface protocol, the files are moved to the USB stick and are therefore no longer
present on the IPC.
• Once data transfer to the USB stick is complete, the "Saved, OK" message appears. The switch can no
longer be pressed until a new interface protocol is available.
• The USB stick can be removed again after backing up the data.

Heating water pump via frequency converter (FC):

The activation of the heating water pump by means of the frequency converter is shown in the upper part of
the window. To do so, a PI controller is used which outputs the setpoint (0 to 10 V) to the frequency convert-
er. The setpoint can also be set manually.

Parameters for frequency converter (FC):

The control parameters of the PI controller are identical with those of the water temperature controller. But
there are no warm-up, run-on times or start setpoint.
