GSC400 Operation and Basic User Configuration
5.1
Power-up
The very first time the controller is powered up the unit will go through an initialization
where all the configurable settings are set to factory default values. This will happen
only on the first power-up. Once the initialization is finished, the controller will display
the firmware and hardware version on the screen and flash the indicator lamps on the side
of the controller (this will also occur during all subsequent power-ups).
The controller will then enter the OFF mode. By default, it is possible to manually start
the generator in the OFF Mode. The user can disable manual start in OFF mode in the
basic menu (in which case the GSC400 must be in the AUTO mode to manually start the
generator). See section 5.9.2 on page 29.
Pressing the Auto key will cause the controller to enter the AUTO mode. From this
mode, the user can manually put the controller into RUN mode (i.e. start the generator) or
the controller itself will be able to start the generator automatically if required (e.g.
remote start capability on low battery if enabled).
The controller has the ability to remember whether it was in the OFF or AUTO mode the
last time it was powered up and will reenter that mode when it is repowered.
5.1.1
Controller Alarming
If the
emergency stop input
of the digital input terminal is not connected to ground the
controller will alarm and display “Emergency Stop” when connected. Emergency Stop
also forces the controller to the OFF mode. To prevent this ground the emergency stop
input (pin 9) to either of the grounds (pins 11 or 12) on the digital input terminal. See
Figure 4 on page 15.
5.2
Remote Start Contacts / Emergency Stop
The GSC400 has a dedicated
remote start contact
located on the digital input connector.
See Figure 4 on page 15 for the location of the remote start contact. A grounded signal
on the contact when the controller is in AUTO Mode (see below for more information on
the AUTO Mode) will cause the controller to start. Removing the ground will cause the
controller to go back into AUTO Mode.
It is also possible to set one of the programmable digital inputs as a remote start contact.
This feature works the same way as the dedicated remote start (active = start). See Table
15 on page 67 for more information on the digital input features.
