CM
Output of the SOL10A Coil Driver in the CM. It provides the negative path to complete the circuit to energize SOL10A when the Rotate Command Pot (VR3) is rotated CW from its learned neutral position or a Reach function is requested.
De-energized: B+ Energized: approx. 24V

REACH/ROTATE DIR B
Output of the SOL10B Coil Driver in the CM. It provides the negative path to complete the circuit to energize SOL10B when the Rotate Command Pot (VR3) is rotated CCW from its learned neutral position or a Reach function is requested.
De-energized: B+ Energized: approx. 24V

TRAVERSE DIR A
Output of the SOL9A Coil Driver in the CM. It provides the negative path to complete the circuit to energize the SOL9A coil when the Traverse Command Pot (VR4) is rotated CW from its learned neutral position.

REACH SELECT SOL
Output of the SOL11 Coil Driver in the CM. It provides the negative path to the circuit to energize SOL11. This output is automatically present to permit reach/ retract operation during a traverse function when the CM has determined that Traverse Feedback Pot (VR5) voltage at JPC24-18 indicates that the mid-point of the platform width has been exceeded and that the forks are fully nested. Once the mid-point has been attained, a REACH SOL output can be energized by rotating the Traverse Command Pot (VR4) slightly out of its learned neutral position.

WIRE SENSE
Return path to the CM for the voltage used to operate the 3 green LEDs that make up the guide wire/rail icon. The LEDs are OFF when the AUTO/MAN switch (S4) is in the MAN position. The LEDs flash if a guide wire is sensed when S4 is in the AUTO position. They remain illuminated when the truck is locked on the guide wire.
