down and re-enter the AUTO mode if it initiated a generator start.
When the controller is in the RUN mode, generator parameters will be displayed
on the screen to allow the user to monitor the engine status. These include
engine speed, generator voltage and current, and engine temperature as well as
others. The parameters are displayed in groups and the screen scrolls between
the various groups. The Page Roll Display menu option controls how long each
parameter group is displayed on the screen before moving on to the next group.
See Table 23 on page 90 for more information.
If an analog input is set to a Switch the GSC400 will display “SW” where
normally the value is displayed. If the analog input is set to J1939 or an analog
input then the actual value of the input will be displayed.
4.4.4.1 Locking the GSC400 Screen While in RUN Mode
When in the RUN mode the GSC400 LCD screen can be locked to display a
particular parameter group. To do this press the up or down keys to scroll to the
parameter group you wish to view and then press the ENTER key to lock the
screen. You will see a lock symbol displayed on the top right hand side of the
display just under the date and time.
To unlock the screen press “Enter” again which causes the lock symbol to
disappear and the screen will start to scroll though the parameter groups again.
The screen will automatically unlock after 10 minutes.
4.4.4.2 Idle Mode
For generators that have the capability of idling at a lower speed than the normal
operating speed the GSC400 controller has an Idle Mode feature that
suppresses the warnings and failures for under-voltage, under-frequency, and
under-speed. The GSC400 displays “Idle Running” when this feature is
enabled.
