When system is “S1 Gens S2 Gens S3 Mains”, S1, S2 start/stop; when system is “S1 Gens S2
Mains S3 Gens”, S1, S3 start/stop; when system is “S1 Mains S2 Gens S3 Gens”, S2, S3 start/stop;
when system type is “S1 Gens S2 Gens S3 Gens”, S1, S2, S3 start/stop.
Gen Start Mains NG:
when mains is abnormal, S1 or S2 or S3 (determined by start priority) starts to
supply. Genset close relay will active after genset is normal.
Remote Start on Load:
Detect S1 or S2 or S3 start output according to start priority and start mode.
Genset close relay will active after genset is normal.
Remote Start off Load:
Detect S1 or S2 or S3 start output according to start priority and start mode.
Genset S1 close relay, S2 close relay and S3 close relay are deactivated after genset start.

Start.
Cycle Run Start:
If system is “S1 Gens S2 Gens S3 Mains”, when S3 Mains is abnormal or remote start is active,
S1 and S2 cycle run start according to the cycle run time. At the first time to start the genset, choose
“S1 Start” or “S2 Start” depends on “Priority”. e.g. S1 starts firstly if “S1” has higher priority. Then S1
cycle run countdown is started according to the preset delay. At the same time, genset fault delay will
be initiated. If S1 genset is normal before the fault delay has expired, S1 will take load; S2 starts after
the preset S1 cycle run delay has expired and the S2 loading process is same as S1. S1 will stop
automatically after the S2 has taken load successfully. S1 and S2 will cycle run in this way alternately
until the remote start signal deactivated.
During the start process, if there is genset fault alarm (genset fault delay overtime or genset fault
input is active), fail to close or load inhibit alarm occurs, the starting genset will be stop immediately
and the additional genset will start automatically.
During the cycle run process, if “Manual Mode” is selected, the current status will be hold and the
“cycle run countdown” will be suspended.
Master-Slave Gens
Master genset will start when mains abnormal or 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 run genset will running continuously until the
remote start signal deactivated or mains normal.
Balance Run
The gensets which has the shortest running hours will start when mains abnormal or 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 be stop immediately and the additional genset will start automatically. Otherwise, the current
genset will running continuously until the remote start signal deactivated.
