Model 9600/9700 Swing-Reach ® Lift Truck
Pinout Matrix Function Description
Voltage Source
Voltage User
Neutral: 2.25 to 2.75V Left: 0.5 to 1.5V Right: 3.3 to 4.3V
VR4
CM
Return path to the CM for the voltage used to operate the yellow LEDs of the triangular seeking wire/rail icon on the Supplemental (Supp) Display. The two triangular seeking wire/rail icon are OFF when the AUTO/ MAN Switch (S4) is in the MAN position. They flash if no guide wire or rail is detected and S4 is in the AUTO position. They remain illuminated when the truck is determined to be locked on the guide wire or in the rail.
Illuminated: <1V Not illuminated: 12V
Supp Display
CM
CUSTOM IN 2
Custom input to the CM. Used for special optional inputs. When used, the ability to disable lift and reduce travel speed is possible.
Open: >4V Closed: <1V
Optional Device
CM
JPC10-3
STR4
Return path to the CM for the voltage used to operate the first right of center yellow LED of the drive wheel direction icon on the Supplemental Display.
Illuminated: <1V Not illuminated: 12V

JPC10-4
DGND
Return path for Mini Power Supply and Reach Prox.
Measure battery voltage to TP1 (B+) to verify connections. Then check for <0.3V wrt TP4.

JPC4-4
TRAVERSE/ REACH CMD
Variable voltage input from the Traverse Pot (VR4). The CM monitors this voltage to determine the direction and speed of the traverse request when VR4 is rotated from its learned neutral position. The CM also uses this voltage to generate an error code if the voltage is not within its specified limits.
