triggered. The controller will display a message and sound the alarm in the case
of a warning or will shut down and sound the alarm in the case of a failure.
3.4.1 Switched Inputs
If using a switch, it must be Uswitched to groundU but can be either normally open
or normally closed. Set the “USignal SourceU” menu to “Switch Input” and the
USwitch SettingU” menu to “Closed = Fail” for normally open switches or “Open =
Fail” for normally closed switches.
If the Signal Source is set to a switch, in the RUN mode (see section 3.4 on page
82) the controller will display “SW” in place of the value that would be displayed if
it was set to J1939 or Sender.
Warnings and Failures: Except for a couple of cases when set to a switch the
GSC400 will shutdown if the switch becomes active. The cases where this does
not happen are:
1. Fuel Level– The fuel level can be set to warn or fail (shutdown) if the
switch becomes active. This is controlled in the Switched Setting
submenu of the Fuel Level menu.
2. Low Engine Temperature – When the switch becomes active, the
GSC400 generates a warning only. No failure setting is possible.
