Jib Retaining Pin Simplified for T85

If pin is unlocked jumper 24 to 27 and S916 should display in erection aid.

If pin is locked, jumper 24 to 26, and S918 should display

**Note** If the jib retaining motor inductive sensor B911N (tells the crane the screw is backed off) is faulty, the Erection Screen will still show —-.  Once the S916S has been acted on, it sends power to B911N, and once B911N detects metal, it powers K916A which tells the processor the pin is released.
