MAIN LIFT DOWN
VALVE –
OPEN CIRCUIT 33184 1 Deactivate output J2-22 Main Lift
Down Valve.
The UGM detects an open circuit at
this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
MAIN LIFT DOWN
VALVE –
SHORT TO
GROUND 33185 1 Deactivate output J2-22 Main Lift
Down Valve.
Decouple/disable current feedback
input J3-2 Lift Return (Disables Lift
Up and Down).
The UGM detects a short to ground
at this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
MAIN TELESCOPE
OUT VALVE – OPEN
CIRCUIT 33186 1 Deactivate output J2-35 Main
Telescope Out Valve.
The UGM detects an open circuit at
this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason why.
Power cycled.
MAIN TELESCOPE
VALVES – SHORT
TO BATTERY 33187 1 Deactivate output J2-35 Main
Telescope Out Valve.
Deactivate output J2-34 Main
Telescope In Valve.
Decouple/disable current feedback
input J3-4 Telescope Return
(Disables Telescope Out and In).
The UGM detects a short to battery
at this output.
Power cycled.
MAIN TELESCOPE
OUT VALVE –
SHORT TO
GROUND 33188 1 Deactivate output J2-35 Main
Telescope Out Valve.
Decouple/disable current feedback
input J3-4 Telescope Return
(Disables Telescope Out and In).
The UGM detects a short to ground
at this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
MAIN TELESCOPE
IN VALVE – OPEN
CIRCUIT 33189 1 Deactivate output J2-34 Main
Telescope In Valve.
The UGM detects an open circuit at
this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
MAIN TELESCOPE
IN VALVE – SHORT
TO GROUND 33190 1 Deactivate output J2-34 Main
Telescope In Valve.
Decouple/disable current feedback
input J3-4 Telescope Return
(Disables Telescope Out and In).
The UGM detects a short to ground
at this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
FORK TILT UP
VALVE –
OPEN CIRCUIT 33191 1 Deactivate output J2-8 Fork Tilt Up
Valve.
The UGM detects an open circuit at
this output or the UGM detects a
CURRENT FEEDBACK LOST
condition and sets an internal flag to
determine if this fault condition is
the reason for the fault.
Power cycled.
