ADJUSTING CENTER PARTING CAR DOORS
6.1 Adjusting the stop roller:
Referring to figure 5A, we recommend adjusting the driven car door so that it leads the
hoistway door by
1/4”. This will make the car door more closely match the hoistway door when fully open. Adjust the stop
roller on the drive pulley so that the closing doors will be stopped by the roller as they meet. Do not have
pressure on the meeting car doors, otherwise it will place unwanted stress on the arms.
6.2 Adjusting the release roller and clutch:
Referring to figure
5A, adjust the lock release rollers so that they will clear the clutch by about 3/16” when
the car doors are in their final closed position and the operator stop roller is against the stop plate. Adjust
the clutch cam as per figures 5B and 5C. The clutch should retract as late as possible in the closing cycle.
