JPC14-7
B+K2
B+K2 supplied from the OTM Cable and the K2 energized: Fuse/Relay Card when the TM has B+ 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.

JPC12-8
L/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.
