Emergency Brake or Gripper fault
The Emergency brake or the Gripper has dropped or the Car Top relays are not active.
Manually reset the emergency brake. If the problem persists check the inputs on the Car Top
board and Relays: RGM, DZM, RGC, DZC.
Perform a Dip1+Reset on the Cartop bd. If that doesn’t work then toggle the Cartop Inspection
switch on then off.
The gate switch is jumped out or inoperative
During a door cycle the controller expects the status of the gate switch to change. This fault
indicates no change occurred and power was never removed from the GSW inputs during the
door cycle.
Check the Cartop board inputs for a jumped or shorted wire.
The hall locks are jumped out
During a door cycle the controller expects the status of the hall locks to change. The correct
sequence is that the Gate Switch is made up first and then the Hall locks are made up.
This fault indicates that the switching sequence is opposite or no change occurred and power
was never removed from the inputs during the door cycle.
Check the Machine Room board inputs for a jumped or shorted wire.
Adjust door cams to activate gate switch before hall interlocks are activated.
For troubleshooting purposes, this function may disabled by the detect door jumpers option in
door set up. Set this value to “no” if this is the case.
Brake Pick Switch failed to close
The controller is programmed to monitor the mechanical status of the brake.
Check the brake to see if mechanical lift occurs at the appropriate time. Next check to see if
the brake inputs are registering appropriately. The most likely cause is the actual brake pick
switch on top of the brake. Make sure it’s opening and closing fully when the brake activates.
Check to make sure that the 24v BPS line from the switch is NOT run in the same conduit with
high power lines. It may pick up an induced voltage causing intermittent faults. Run a separate
line to isolate from possible inductive voltages.
Locate the fault in “MAIN MENU | FAULTS | LOGGED FAULTS” and see if there are any other
faults that occurred at the same time and verify that they weren’t the cause of the F148: Brake
Pick Switch fault.
