7.2 AUTO START/STOP
7.2.1 START CONDITIONS
7.2.1.1 INPUT START
Set input port as "Remote Start On Load" or "Remote Start Off Load", both could not be set
simultaneously.
Remote Start on Load: When genset start output, gen close relay will active after gen is normal;
when the input inactive, genset will stop automatically.
Remote Start off Load: When genset start output, mains close relay will active after mains is
normal; when the input inactive, genset will stop automatically.
7.2.1.2 GEN START MAINS NG
When mains is abnormal, genset start outputs, gen close relay will active after gen is normal.
7.2.2 S1 GEN S2 GEN START/STOP
When system is "S1 Gen S2 Gen", input port setting is as follows:
Remote Start on Load: Detect S1 or S2 start output according to start mode. Gen close relay will
active after gen is normal.
Remote Start off Load: Detect S1 or S2 start output according to start mode. Both gen S1 close
relay and S2 close relay are deactivated after genset start.
Start Mode: Cycle Run, Master-Slave Run, Balanced Time Run, None.
Cycle Run
When remote start is active, S1 and S2 will cycle start according to the cycle run time. When
firstly start the genset, choose "S1 Start" or "S2 Start" depends on "Priority". e.g. S1 start firstly if "S1"
has higher priority. Then S1 cycle run countdown is started according to the preset delay. At the same
time, genset fault identification will be initiated. If S1 gen is normal before the fault identification 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 after the S2 takes 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 (fault identification 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.
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 Run
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
