Master genset will start when remote start signal is active. During the start process, if there is
genset fault alarm (genset supply delay overtime or genset fault input is active), fail to close or load
inhibit alarm occurs, the starting genset will stop immediately and the additional genset will start
automatically. Otherwise, the master genset will run continuously until the remote start signal
deactivated.
Balanced Run
The genset which has the shortest running hours will start when remote start signal is active.
During the start process, if there is genset fault alarm (genset supply delay overtime or genset fault
input is active), fail to close or load inhibit alarm occurs, the starting genset will stop immediately and
the additional genset will start automatically. Otherwise, the current genset will run continuously until
the remote start signal deactivated.
In system of “S1 Gen S2 gen” to start/stop genset should meet following several conditions:
1)
It is active in Auto mode;
2)
System type set as “S1 Gen S2 Gen”;
3)
Output should be set as “S1 Genset Start” and “S2 Genset Start”;
4)
Input should be set as “S1 Genset Fault Input”, “S2 Genset Fault Input” and “Remote Start On
Load” or “Remote Start Off Load”;
5)
Should set the system as “Two Gensets Start Mode”;
6)
Should configure set “Genset Supply Delay”, If start mode is cycle run, also should set “S1
Cycs Run Time”, “S2 Cycs Run Time”.
Among input ports, “S1 Genset Fault Input”, “S2 Genset Fault Input” are selective setting, genset
fault can be judged by “Genset Supply Delay” and there no need to inquire the fault alarm via input
port.
When two gensets start mode configured as “None”, there is no genset start signals output.

SCHEDULED RUN
Once “Scheduled Run” enables, users can set the scheduled start time. Controller will send start
signal at preset start time. Start signal will be deactivated after the start delay has expired.
“Scheduled Run On Load” or “Scheduled Run Off Load” can be set.
Scheduled Run On Load:
When the input is active, genset close relay will active after genset is
normal.
