2.21 DRIVE & O/R PREVENTED - PLACE BOOM ON REST
Distress Lamp: 2
In Platform Mode, an attempt was made to operate Drive or Outriggers but the Boom was not detected by the Turntable posi-
tion sensor at X073, or an error was detected with the sensor. When the boom is against the rest, TURNTABLE1 input,
X074.3 = +B and TURNTABLE2 input, X074.4 = 0V. This could be caused by the boom not being properly stowed on the
rest, an obstruction over the switch, the switch adjusted too far from the boom (should be within 0.188" of the boom), or a faulty
transport limit switch or turntable position switch. If an error has been detected, the switch must be reset before drive will function.

2.22 DRIVE & O/R PREVENTED - SET HAND BRAKE
Distress Lamp: 2
In Platform Mode, an attempt was made to operate Drive or Outriggers but the Hand Brake was not detected by the hand
brake position sensor at X072 as set (applied) or an error was detected with the sensor. If the hand brake appears to be in
the proper position, examine the Hand Brake Sensor wiring and adjustment. When the hand brake is applied, BRAKE1 input,
X074.5 = +B and BRAKE2 input, X074.6 = 0V.This could be caused by the brake linkage or cable not being properly
adjusted, an obstruction over the switch, the switch adjusted too far from the cylinder (should be within 0.188" of the extended
cylinder), or a faulty switch. If an error has been detected, the switch must be reset before drive will function.
