4.5 GSC400 Start / Stop Behavior
THE LCD WILL TURN OFF DURING THE FIRST 2 SECONDS OF CRANKING
TO LIMIT THE VOLTAGE DIP EFFECT ON THE CONTROLLER DURING
CRANKING.
Since the GSC400 startup and shutdown behavior can be configured by the
manufacturer the exact startup and shutdown behavior can vary. Behaviors such
as the amount of time to wait before starting, preheat, crank time, etc, all are
programmable.
There are three ways to start the generator (start conditions):
1. Modbus – Sending a “Start” using the appropriate register.
2. Remote Start Contacts (RSC) – Pins 10 of the digital input connector or
setting Switched Input A to H to the Start/Stop feature.
3. Run key – Located on the GSC400 front panel.
There are two features that can automatically start the generator:
1. Battery Recharge (if enabled)
2. Exerciser (if enabled)
The battery recharge and exerciser options will only start the generator when the
GSC400 is in the AUTO mode. These features will not interrupt a shutdown.
When the controller is in the AUTO mode the three manual start conditions
above can be used to start the generator. When the controller is in the RUN
mode it will display the reason for the start on the screen (Modbus Run, Remote
Start Run, Manual Run …).
Stopping the Generator
The off key on the front panel can always be used to place the GSC400 in the
OFF mode.
If the controller is in the RUN mode due the remote start contacts or Modbus, for
the first 10s either of the two can be used to place the controller back in the OFF
state (although the remote start contacts cannot be used to stop the generator
unless it was the cause of start). After this 10s period only the start condition that
caused the start can be used to place the controller back in the AUTO or OFF
mode.
Preventing a Stop when in Cool Down
Once the GSC400 is in cool down and another start condition was received the
controller will exit cool down and remain running. It will display the new start
condition on the screen.
