23. Temperature control
This input is part of the idle mode function. When the input is high, then the genset
starts. It starts at high or low speed, depending on the activation of the low speed input.
When the input is deactivated, then the genset goes to idle mode (low speed = ON), or
it stops (low speed = OFF).
24. Battery test
Activates the starter without starting the genset. If the battery is weak, the test will
cause the battery voltage to drop more than acceptable, and an alarm will occur.
25. Mains Okay
Disables the "mains OK delay" timer. The MB close sequence will begin when the input
is activated.
26. GB close inhibit
When this input is activated, then the generator breaker cannot close. This input is used
where an external PLC or other equipment controls when load is put on the genset.
27. MB close inhibit
When this input is activated, then the mains breaker cannot close.
28. Enable mode shift
The input activates the mode shift function, and the EMS-GC10 will perform the AMF
sequence in case of a mains failure. When the input is configured, the setting in
parameter 7081 (mode shift ON/OFF) is disregarded.
29. Start enable
The input must be activated to be able to start the engine.
NOTE: When the genset is started, the input can be removed.
30. Alternative start
This input is used to simulate an AMF failure and this way run a full AMF sequence
without a mains failure actually being present.
31. Switchboard error
The input will stop or block the genset depending on running status.
32. Total test
This input will be logged in the event log to indicate that a planned mains failure has
been made.
33. GB spring loaded
EMS-GC10 genset controller unit will not send a close signal before this feedback is
present.
