Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
MACHINE SETUP > JIB = YES
The PM detects an open circuit at this output and
reports it to the UGM
MACHINE SETUP > JIB = YES
The PM detects a short to battery at this output and
reports it to the UGM
MACHINE SETUP > JIB = YES
The PM detects a short to ground at this output and
reports it to the UGM
MACHINE SETUP > JIB = YES
The PM detects an open circuit at this output and
reports it to the UGM
MACHINE SETUP > JIB = YES
The PM detects a short to battery at this output and
reports it to the UGM
MACHINE SETUP > JIB = YES
The PM detects a short to ground at this output and
reports it to the UGM; detection occurs for PWM output
approximately ≤ 15% or for STG condition.
UGM fuel sensor analog input J2-25 detects a voltage
higher than 2.50 volts (A/D > 512)
UGM fuel sensor analog input J2-25 detects a voltage
less than or equal to 0.3 volts (A/D < 61)
