Load take over
Auto mode description
Back synchronizing ON (Closed Transition)
The purpose of the load take over mode is to transfer the load imported from the mains to the
gen-set for operation on generator supply only.
When the start command is given, the gen-set will start and synchronize the generator breaker
to the mains. When the generator breaker is closed, the imported load is decreased (the power
is being transferred to the gen-set), until the load is at the open breaker point. Then the mains
breaker opens.
When the stop command is given, the mains breaker is synchronized to the generator and after
closure the gen-set is deloaded, cooled down and stopped.
A 4-20mA transducer is used for indication of the power imported from the mains.

Semi-auto mode
When the generator breaker is closed, and the mains breaker is opened, the unit will use the
nominal frequency as set point for the speed governor.
When the generator is paralleled to the mains, it will be controlled, so the imported power from
the mains will be kept at 0 kW.

The unit automatically starts the gen-set and switches to generator supply at a mains failure
after an adjustable delay time. It is possible to adjust the unit to change to gen-set operation in
two different ways.
In both cases, the generator breaker will be closed, when the generator voltage and frequency is
OK, and the mains breaker is open.
When the mains returns, the unit will switch back to mains supply and cool down and stop the
gen-set. The switching back to mains supply is done without back Synchronization (Open
Transition), when the adjusted ‘mains OK delay’ has expired.

General semi-auto mode description
The unit can be operated in semi-automatic mode. Semi-auto means that the unit will not initiate
any sequences automatically, as is the case with the auto mode. It will only initiate sequences, if
external signals are given.
An external signal may be given in three ways:
1. Push-buttons on the display are used
2. Digital inputs are used
3. Modbus command.
When the gen-set is running in semi-auto mode, the unit will control the speed governor.
The following sequences can be activated in semi-auto:

General block mode description
When the block mode is selected, the unit is locked for certain actions. This means that it cannot
start the gen-set or perform any breaker operations.
To change the running mode from the display, the user will be asked for a password, before the
change can be made. It is not possible to select ‘block mode’, when running feedback is present.
The purpose of the block mode is to make sure that the gen-set does not start for instance
during maintenance work.
If the digital inputs are used to change the mode, then it is important to know that the input
configured to block mode is a constant signal. So, when it is ON the unit is in a blocked state,
and when it is OFF, it returns to the mode it was in before block mode was selected.

Sequences
The following contains information about the sequences of the engine, the generator breaker
and, the mains breaker. These sequences are automatically initiated if the auto mode is
selected, or if the commands are selected in the semi-auto mode.
In the semi-auto mode the selected sequence is the only sequence initiated (e.g. press the

Running feedback
4 different types of running feedback can be used to detect if the motor is running. Refer to
menu 4300 for selection of the running feedback type.
The running detection is made with a built-in safety routine. The running feedback selected in
menu 4300 is the primary feedback. At all times all the types of running feedback is used for
running detection. If for some reason the primary choice is not detecting any running feedback,
the starter relay will stay activated for additionally 1 second. If a running feedback is detected
based on one of the secondary choices, the gen-set will start. This way the gen-set will still be
functional even though a tacho sensor is damaged or dirty.
As soon as the gen-set is running, no matter if the gen-set is started based on the primary or

Mode overview
The unit has four different running modes and one block mode. For detailed information see
page 9.
Auto
In auto mode the unit will operate automatically, and the operator cannot initiate any sequences
manually.
Semi-auto
In semi-auto mode the operator has to initiate all sequences. This can be done via the pushbutton functions, modbus commands or digital inputs. When started in semi-automatic mode,
the gen-set will run at nominal values.
Test
The test sequence will start when the test mode is selected.
Manual
When manual mode is selected, the binary increase/decrease inputs can be used (if they have
been configured) as well as the start and stop push-buttons. When starting in manual mode, the
gen-set will start without any subsequent regulation.

nfigured with different minimum
and maximum settings. In this case the settings ‘start derate point’ and
‘slope’ use these new settings.
Time dependent start/stop
The purpose of the time dependent start/stop function is to be able to start and stop the gen-set
automatically at specific times each weekday or certain weekdays. Auto mode must be activated
for this function. Up to 8 commands can be used for either start or stop. The settings are set up
through the PC utility software. Each command can be set for the following time periods:
Individual days (MO, TU, WE, TH, FR, SA, SU)
•
MO, TU, WE, TH
•
MO, TU, WE, TH, FR
•
MO, TU, WE, TH, FR, SA, SU

It is necessary to use the PC utility s
start/stop function.
Derate gen-set
The purpose of the derate function is to be able to reduce the maximum output power of the
gen-set, if specific conditions require this. An example of such a condition is the ambient
temperature. If the ambient temperature increases to a level where the cooling water coolers
decrease in cooling capacity, it will be necessary to reduce the power of the gen-set.
If the gen-set is not derated, alarms and shutdown events will very likely occur.
Input selection
The derate function can be configured to one of the following inputs:
Input

Analogue input 100 X
VDO input 105 X

Refer to the type label for information about engine interface selection.
Derate parameters
The parameters that define the derate characteristics are the following:
Start derate point

This is the setting where the derating must start. The setting can be in mA (max. 20mA) or
in centigrades ºC (max 200ºC).

Adjust the derating speed. The adjustment is in percent per unit, i.e. if the 4…20mA input is
used (analogue 100), then the derating will be in %/mA, and if the PT100/VDO input is
used, then the derating will be in %/C.

All activated alarms must be configured with a fail class. The fail classes define the category of
the alarms and the subsequent alarm action.
Six different fail classes can be used. The tables below illustrate the action of each fail class

The unit is able to monitor the maintenance intervals. The menu is available in the system setup.

unit will display an alarm. The ‘alarm acknowledge’ function resets this alarm.
When acknowledging the alarm, the timer will be reset and a new service timer alarm will only
reoccur after the adjusted time has elapsed. The running hours is counting, when the running
feedback is present.
Wire break detection
If it is necessary to supervise the sensors/wires connected to the analogue inputs (4-20mA,
VDO and PT100), then it is possible to use the menus 4370-4430 depending on the HW options
available in the unit. If the measured value on the input is outside the normal dynamic area of
the input, it will be detected, as if the wire has made a short circuit or a break. An alarm with a
configurable fail class will be activated.

The table consists of the following possible adjustments:
Set point: The alarm set point is adjusted in the set point menu. The setting is a
Timer: The timer setting is the time that must expire from the alarm level is reached
Relay output A: A relay can be activated by output A.
Relay output B: A relay can be activated by output B.
Enable: The alarm can be activated or deactivated. ON means always activated, RUN
Fail class: When the alarm occurs the unit will react depending on the selected fail class.
It is also possible to configure the parameters by using the PC utility software. It will be possible
to make the same configurations as described above.
By using the PC utility software some extra functionalities are available. For all the protections it
is possible to make an automatic acknowledgement of the alarm. Usually it is important when
the mains protections are used, as the sequences are blocked until the alarm is acknowledged.
The parameter lists for the available options are presented in the documents
