Just got a new bldg with tac50s. The car runs fine on inspection in the down, but in the up it shuts down after 1 run with a 1547 bslm. Brake swts look fine. Not sure if it's a tach issue since it's directional. My faults on my service tool doest have 1547. I don't have any manuals or fault log books. Any idea guys?

The brake switch inputs are susceptible to noise. They should be in shielded cable with the shield grounded on 1 end. You can also wire a resistor from the inputs to P24 to keep them honest. What kind of machines are you working with?

BTW, I've never even seen BSLM2 input used before. And I only found that fault in the TAC32-T manual.

U could have a roll back issue. If you have a 10k drive increase karb adjustment on the drive to limit rollback on your start

Thank you for good info. Is there a pick sequence that the process of looks at, like balm needs to pick before bake or has to drop out first? I get run monitor faults if the brake switch are a touch out of wack.
