Balance Gen Hours
The genset which has the shortest running hours will be started when remote start signal is active.
During the start process, if current genset faults (power supply delay is overtime or ), close failure, load
inhibition occur, current genset is stopped immediately and start the other genset, otherwise master
genset starts until remote start is inactive.
For the system of “S1 Gens S2 Gens” to start/stop genset, it should meet following several
conditions:
1) It is active in Auto mode;
2) System type is set as “S1 Gens S2 Gens”;
3) Output port is set as “S1 genset start” and “S2 genset start”;
4) Input port is set as “S1 genset fault input”, “S2 genset fault input”, and “remote start on load”
or “remote start off load”;
5) It is need to set “S1 Gen S2 Gen Start Mode”;
6) It needs to configure and set “Genset Supply Delay”. If start mode is cycle gen start, “S1
Cycle Work Time”, “S2 Cycle Work Time” are also needed to set.
Among input ports, “S1 Genset Fault Input”, “S2 Genset Fault Input” are optional settings, Genset
faults can be judged by “Genset Supply Delay” and there is no need to inquire the fault alarm via input
port.
When S1 Gen S2 Gen start type is configured as “Not Used”, there is no genset start signals
output.
