START/STOP GENSET IN AUTO MODE
8.2.1
START CONDITIONS
—
Input Port Start
Configure "Remote Start On Load" or "Remote Start Off Load", they cannot be set at the same time.
Remote Start On Load: Genset start outputs, when generating is OK, gen closes; when it is inactive,
genset start output signal is disconnected.
Remote Start Off Load: Genset start outputs, when mains is OK, mains closes; when it is inactive,
genset start output signal is disconnected.
—
Mains Abnormal Start
When mains is abnormal, genset start outputs; when generating is OK, gen closes.
8.2.2
START/STOP OF TWO GENSETS
System type is "S1-Gen S2-Gen", and input port settings are as below.
Set programmable input port to "Remote Start On Load", or "Remote Start Off Load", and they cannot be
set at the same time.
Remote Start On Load: According to start method, judge S1 or S2 start output; when generating is OK,
gen closes;
Remote Start Off Load: According to start method, judge S1 or S2 start output; after gensets are started,
both gen S1 and S2 don't close.
Start method of two gensets: Cycle Gen Start Mode, Master-Slave Gen Mode, Balance Gen Hours Mode,
Not Used.

Cycle Gen Start
When remote start is active, S1 and S2 will start according to cycle running time. For the first start,
controller selects S1 or S2 start based on master status; for example, if S1 is master, then S1 starts first.
then countdown starts based on the pre-set S1 cycle running time, and at the same time genset fault
identification countdown is initiated. Before the end of fault identification countdown if S1 generating is
normal, S1 takes the load as soon as it is normal. After the end of S1 cycle running countdown, S2
starts and S2 cycle running countdown is initiated; at the same time genset fault identification
countdown starts; Before the end of fault identification countdown, if S2 generating is OK, it will take
the load as soon as it is normal. S1 stops. It goes in this way until remote start is inactive.
In the process of genset start, if genset fault (power supply delay overtime or genset fault input is
active), failed to close, load inhibit, occurs, controller will immediately stop the current started genset,
and start the other genset.
During the process of cycle running, if it transfers to manual mode, it will keep the current status, and
stop the cycle running timing.
—
Master-Slave Gen Mode
When remote start is active, master genset starts. In the process of genset start, when genset fault
(genset supply delay overtime, or genset fault input), failed to close, load inhibit, occurs, controller will
immediately stop the current started genset, and start the other genset. Otherwise master genset
continues starting until remote start is inactive.
—
Balanced Running Start
When remote start is active, the short accumulated running unit starts, when the current unit fault
during the starting process (Gen supply delay or fault input), close failure, inhibit on load, try to stop the
current running unit and start another unit, otherwise the current unit will continue to start running until
the remote start is inactive.
The following conditions are required to do genset start/stop when system type is "S1-Gen S2-Gen".
