input J3-14 Aux Return (Disables
Auxiliary Function-A and
Function-B).
Deactivate and inhibit the
Continuous Auxiliary Hydraulics
feature.
Turn OFF the Continuous Auxiliary
Hydraulics indicator.
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.

FUNCTION-B VALVE
– OPEN CIRCUIT 33199 1 Deactivate output J2-20 Auxiliary
Function-B Valve.
Deactivate and inhibit the
Continuous Auxiliary Hydraulics
feature.
Turn OFF the Continuous Auxiliary
Hydraulics indicator.
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.
