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 the input is active, genset close relay will active after genset is
normal; when the input inactive, genset will stop automatically.
Remote Start off Load: When the input is active, 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 TWO GENSETS START/STOP
When system is "S1 Gen S2 Gen", input port setting is as follows:
Set input port as "Remote Start On Load" or "Remote Start Off Load", both could not be set
simultaneously.
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 genset S1
close relay and S2 close relay are deactivated after genset start.
Start Mode: Cycle Run, Master-Slave Run, Balanced Run, None.
Cycle Run
When remote start is active, S1 and S2 cycle run start will 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 delay will be initiated. If S1 genset is normal before the fault delay has expired, S1
will take load; S2 start 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 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 alarm (genset fault 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.
During the cycle run process, if "Manual Mode" is selected, the current status will be hold and the
"cycle run countdown" will be suspended.
