Deadman Up: >4V Down: <1V
S9
CM
SIDEGATE RIGHT Input voltage to the CM from the optional Right Sidegate switch (S60). The CM uses this voltage to determine whether the sidegate is raised or lowered. S60 is closed when the right sidegate is down.

JPC22-5
CHA-E1
Part of the steering request when the encoder is rotated. It is a square wave signal identical to CHB-E1 but different phase. The TM uses the phase relationship of the two channels to determine whether CW or CCW steering is requested. The number of pulses is used to determine the total movement requested.
Moving: approx. 2.5V Not Moving: <1V or 4.75V

SIDEGATE LEFT
Input voltage to the CM from the optional Left Sidegate switch (S61). The CM uses this voltage to determine whether the sidegate is raised or lowered. S61 is closed when the right sidegate down.

JPC22-7
CARRIAGE DEADMAN
Input voltage to the CM from the Carriage Deadman switch (S23). The CM uses this voltage to determine the state of S23. The TM and CM both use this information in conjunction with a travel request to release the brake; however, either cause the brake to apply when it detects a fault, regardless of deadman switch position.

HEIGHT PROX A
Input voltage to the CM from Channel A of the Mini Height Prox Sensor. It switches ON and OFF as it passes over the mini height sensing rail.
Not over metal: >1.7V Over metal: <0.7V

HEIGHT PROX B
Input voltage to the CM from Channel B of the Mini Height Prox Sensor. It switches ON and OFF as it passes over the mini height sensing rail.

DGND
B– for the Carriage Deadman switch (S23).
Measure B+ at TP1 to verify connections. Then check for <0.5V wrt TP4.

LOAD HANDLER DEADMAN
Input voltage to the CM from the Load Handler Deadman switch (S9). The CM uses this voltage to determine the state of S9. When S9 is detected closed (left deadman pedal pressed), the CM enables the use of the Mini-Mast and Load Handler functions. These functions are inhibited if S9 is detected open (left deadman pedal up).
