Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
Machine is in Platform Mode;
The UGM detects one of the following conditions:
Drive joystick is not in the neutral position at Startup;
Drive joystick is not in the neutral position when Foot-
switch becomes active or while DTC 2213, 2221 or 2223
is active
Machine is in Platform Mode;
A Steer input is active when Footswitch becomes active
or while DTC 2212, 2221 or 2223 is active
The PM detects that the Drive or Steer joystick signal
voltage > 8.1V and reports the fault to the UGM.
The PM detects that the Drive or Steer center tap volt-
age is not between 3.31 volts and 3.75 volts and reports
the fault to the UGM
The PM detects that the Lift or Swing joystick signal
voltage > 8.1V and reports the fault to the UGM.
The PM detects that the Lift or Swing center tap voltage
is not between 3.31 volts and 3.75 volts and reports the
fault to the UGM
Machine is in Platform Mode;
The UGM detects one of the following conditions:
Lift and/or Swing joystick is not in the neutral position
at Startup;
Lift and/or Swing joystick is not in the neutral position
when Footswitch becomes active or while DTC 2212,
2213 or 2223 is active
