Other Messages
The following messages are the result of various possible failures or occurrences which may result in
machine interruption.
FUNCTIONS LOCKED - NO VALVE SUPPLY!______________ Flash Code 2/3
GP400 detects no power on P7-1 of the GP400. Check wiring to plug connection; possible
GP400 internal failure.
FAULT: ENERGIZED VALVE____________________________ Flash Code: 3/2
Power on valve output wire at GP400 plugs P4, P5 or P6. Unplug these connectors and cycle e-
stop switch to clear code. Plug in one-at-a-time until code reappears then isolate the circuit (with
voltage) within that plug. If code does not clear, possible GP400 failure.
FAULT: VALVE FEEDBACK HIGH!_______________________ Flash Code: 3/2
On start-up GP400 p-5 pin voltage incorrect, check P5-X wiring for voltage feed back. Possible
GP400 internal fault
FAULT: BAD INTERNAL SAFETY SWITCH!________________ Flash Code: 3/4
At startup, internal feedback of output incorrect, possibly failed output driver; check wiring to P6-
12/13/14/15; possible GP400 internal failure
FAULT: LOW OIL PRESSURE!__________________________ Flash Code: 4/1
Oil pressure switch opened during operation or time out. Check oil pressure, pressure switch,
wiring. Message will appear if engine stops running for reasons other then normal shut down.
FAULT: BAD INTERNAL SLAVE!________________________ Flash Code: 4/2
Malfunction within the GP400 possibly caused by a short circuit in the wiring or high voltage
surge. Replace GP400
FAULT: BAD INTERNAL 5 VOLTS!_______________________ Flash Code: 4/2
5 volt circuit that provides voltage to sensors had failed. Possible short in the wiring or high
voltage surge on supply.
FAULT: BATTERY VOLTAGE TOO LOW!__________________ Flash Code: 4/4
Charge battery and battery connections, check charging system and voltage source
connections.
FAULT: BATTERY VOLTAGE TOO HIGH!__________________ Flash Code: 4/4
GP400 input voltage should be 12 volts. Check battery and battery connections, alternator
output.
FAULT: CHECK HEIGHT 2 SENSOR!_____________________ Flash Code 6/1
Height 2 sensor output over 4.5 volts or under .5 volts. Check height 2 sensor output using the
EZ-Cal (height 2 sensor on CE option only). Possible sensor failure or wire connection failure.
FAULT: CHECK HEIGHT 1 SENSOR!_____________________ Flash Code 6/1
Height 1 sensor output over 4.5 volts or under .5 volts. Check height 1 sensor output using the
EZ-Cal. Possible sensor failure or wire connection failure.
