Just be careful about disabling the brake switch input, I recently was sent to a non contract otis 311 machine, one car was down, that was the car i was supposed to work on, only problem was when i arrived i noticed the brake was smoking on the other car, it never picked and the car just kept running, had to immediately fix the brake problem, and reset the parameter to include the brake switch in the run, this could be a dangerous problem. i realize that older controllers had no brake switches and could run without a brake pick causing the same condition, but this circuit has been incorporated into new controllers for just this reason, it is a safety issue, fix the problem related to the switch and the brake, if it is a controller problem or software problem it must be resolved. just disabling the circuit is not doing any justice for you the mechanic or all of us the riding public. ps after i fixed the original car i was to repair, i shut the other car down for brake reline and load test. some things cannot be overlooked, the brake is number one in my opinion. ask yourself, would you allow your family members to ride this elevator knowing that the brake may not hold a full load after being compromised from heat etc.
