57JPC22-2LOAD HANDLER DEADMAN

Model 9600/9700 Swing-Reach ® Lift Truck

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).

58JPC22-4SIDEGATE RIGHTInput 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.

59JPC22-5CHA-E1Part 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.

60JPC22-6SIDEGATE LEFTInput 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.

61JPC22-7CARRIAGE 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.

62JPC22-9HEIGHT PROX AInput 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.

63JPC22-10HEIGHT PROX BInput 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.
