NOTE: For the ATS without neutral position, it is invalid to press
key.
Remote start/stop
Send remote start/stop signals using MODBUS protocol via RS485 port.
Remote Stop
：
Disconnect the start signal, i.e. stop the running genset.
Remote Start
：
Output the start signal, i.e. start the genset.
Auto start/stop
Input port start/stop operation
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; genset close relay will active when the mains is abnormal while
genset is normal; when the input inactive, genset will stop automatically.
"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.
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.
