Section 8. Theory of Operation Pinout Matrix
Function Description
Voltage Source
Voltage User
Measure battery voltage to TP1 (B+) to verify connections. Then check for <0.3V wrt TP4.
CM
S9
+5V for the Travel Pot (VR1) and the Lift/ Lower Pot (VR2). This voltage is generated by a power supply on the CM. It is also jumpered in the Control Handle harness to supply the Traverse Pot (VR5).
4.75 to 5.25V
CM
VR1, VR2, VR5
LIFT/LOWER CMD
Input from the Lift/Lower Pot (VR2). The TM monitors this voltage to determines the direction and speed of the lift or lower request when VR2 is rotated from its learned neutral position. The TM also uses this voltage to generate an error code if the voltage is not within its specified limits.
Neutral: 2.25 to 2.75V Full Lift: 0.5 to 1.5V Full Lower: 3.3 to 4.3V

TRAVEL CMD
Input from the Travel Pot (VR1). The TM monitors this voltage to determines the direction and speed of the travel request when VR1 is rotated from its learned neutral position. The TM also uses this voltage to generate an error code if the voltage is not within its specified limits.
Neut: 2.25 to 2.75V Full TF: 0.5 to 1.5V Full FF: 3.3 to 4.3V

JPC12-4
LIFT SELECT
Input from the Lift Select switch (S6) that determines whether the TM commands Main or Mini lift. With S6 open (not pressed) only Main lift or lower is commanded when the Lift/Lower Control Pot is rotated in the desired direction from its learned neutral position and with S6 closed (pressed) Mini lift/lower is commanded.
Open: >4V Closed: <1V

ROTATE CMD
Input from the Rotate Command Pot (VR3). The CM monitors this voltage to determine the direction and speed of the rotate request when VR3 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.
Neut: 2.25 to 2.75V Full CW: 0.5 to 1.5V Full CCW: 3.3 to 4.3V
