and Manual run modes. The LCD display will indicate the message: “LOW_BATT”. The LOW battery
warning will be disabled during failure conditions.
LOW OIL INPUT: The Low Oil Input can be wired to a resistive sender or from a NO or NC type
switch. NO / NC refers to the state of the contacts during normal engine operation (engine oil
pressure ok). When utilizing a resistive sender the display units are fixed in PSI by the PC
programming interface, and a failure set-point must be selected from the programming menu.
Note: The oil input failure is disabled during the Oil Bypass time.
HIGH TEMPERATURE INPUT: The high temperature input can be wired to a resistive sender
or from a NO type switch. For proper operation while using a switch, the switch must be the NO type
which closes to ground upon failure. When utilizing a resistive sender the display units are fixed in
Fahrenheit by the PC programming interface, and a failure set-point must be selected from the
programming menu.
Note: The engine temperature failure is disabled during the Oil Bypass time.
FUEL LEVEL/AUXILIARY INPUT: The Fuel level/Aux input can be wired to a resistive sender
or from a NO type switch. For proper operation while using a switch, the switch must be the NO type
which closes to ground upon failure. If this input is used as a sender, no failure will be indicated.
The sender option is solely for Fuel Level/Auxiliary Level Display on the LCD.
3.3 Hour Meter
The controller displays a log of total accumulated generator running hours. Generator Run times will
be displayed on the controllers display screen. The display represents both hours and minutes in the
form 123456:7. The last digit on the hour meter will represent the time in 1/10 of an hour. Please note
that although the hour meter displays time in hours and minutes, it will record up to the nearest
second. If the generator was operated for a 3 minute period and then stopped the running time is
stored in permanent memory and then adding to the next running period. The same would be true if
the controller were to enter a failure mode as the controller would permanently store the remaining
time for the next running cycle.
The maximum hour count is 99,999.9 hours, after which it will continue to display 99,999.9
indefinitely.
3.4 Outputs
If a switched output is overloaded it will go into a fault state and turn off. You must remove power to
the GSC300 for 30s to reset the outputs.
