.2.2. “S1 GEN S2 GEN” START/STOP
When system is “S1 Gen S2 Gen”, input port start/stop function is as follows:
Remote Start on Load:
Detect S1 or S2 start output according to start mode. Genset close relay will
active after genset 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.
S1,S2 Gens Start Type: Cycs Run, Master Run, Balance Run and Not Used.
Start Mode
: Cycle Run Start, Master Run Start, Balance Run Start.
Cycle Run Start:
When 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 the “Master Set” information. e.g. S1 start
at the first time if “S1 Master” is selected. The 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 has take 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 be start automatically.
During the cycle run process, if “Auto Mode” is selected, the current status will be hold and the “cycle run
countdown” will be suspended.
Master Run
Mater genset will be 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 be stop immediately and the additional genset will be start automatically.
Otherwise, the master run genset will running continuously until the remote start signal deactivated.
Balance Run
The gensets which has the shortest running hours will be 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 be stop immediately and the
additional genset will be start automatically. Otherwise, the current genset will running continuously until
the remote start signal deactivated.
In system “S1 Gen S2 Gen” to start/stop genset should meet following several conditions:
1) It is active in Auto mode;
2)
System set as “S1 Gen S2 Gen”
；
3) Output port should be set as
“S1 Genset Start” and “S2 Genset Start ”
；
4) Input port should be set as
“S1 Genset Fault Input”, “S1 Genset Fault Input” and “Remote Start
On Load” or “Remote Start Off Load”;
5) Should set start mode when
“S1 Gen S2 Gen” system is selected;
6)
Should configure setting “Genset Supply Delay”
，
If start mode is cycle run, also should set “S1
Cycs Run Time” and “S2 Cycs Run Time”;
Among input ports, “S1 Genset Fault Input” and “S2 Genset Fault Input” are selective setting, Genset
fault can be judged
by “Genset Supply Delay” and there no need to inquire the fault alarm via input port.
When S1, S2 start type
configured as “Not Used”, there is no start genset signals output
