21JPC12-8L/L_INH_ BYPASS Lift/Lower Inhibit Bypass switch (S7) input to the CM. The voltage on this line determines whether the TM allows lift or lower when the specified Lift or Lower Limit height is reached. When this option is installed, S7 operation may be enabled or disabled in Configure Mode. With S7 open (not pressed), Main Lift/Lower beyond the specified height limit is inhibited. With S6 closed (pressed), further lifting or lowering is allowed.

22JPC12-9ATTACHMENTAttachment switch (S5) input to the CM.S5CM

23JPC12-11AUTO/MANUALAUTO/MAN switch (S4) input to the CM. Activates/deactivates guidance mode (wire or rail). Guidance Mode is activated when S4 is open and off when it is closed.

24JPC12-12DGNDB– for the Horn switch (S3), AUTO/MAN switch (S4), Attachment switch (S5), L/L Pot (VR2), and Travel Pot (VR1).

26JPC14-4BUS1–CAN Communication line between TM, CM, and Display Interface Card.

27JPC14-5+12VD+12V supply to Display Interface Card. Protected by an internal diode in the CM.

28JPC14-7B+K2B+K2 supplied from the OTM Cable and the Fuse/Relay Card when the TM has activated the K2 relay via the relay enable circuit. It provides B+ to SOL7, SOL8, SOL9A/B, and SOL10A/B. It also provides a return path for the suppressors to the coils.
