Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
The UGM detects that Boom Angle Sensor #1 or Boom
Angle Sensor #2 signal voltage > 4.5V.
The UGM detects that Boom Angle Sensor #1 or Boom
Angle Sensor #2 signal voltage < 0.5V.
The UGM detects the following conditions:
The UGM detects < 1 deg change of Boom Angle
