UNINTENDED MOVEMENT
This test is designed to test the operation of the rope gripper in the event that the
car moves unintentionally in a door zone with the Hall AND Car doors open. This
test is normally performed in Normal Operation mode. NOTE: If performing this test
in Inspection MR mode, make sure Binary Parameter 00-110.4 is set to “Yes”.
1. Verify that (DIP A) Dip switch #3 on the machine room SRU controller is not
on.
2. Go to MAIN MENU | SETUP | DOOR SETUP | NO DEMAND DO to “YES” and
SAVE it.
3. Enter a car call to the bottom landing.
4. The car should remain at the landing with the Hall AND Car doors open so
long as another Hall or Car call is not entered.
5. Manually lift the brake by:
a. Install a jumper from M24 to A1 on the PICK relay.
b. Install a jumper from REF to A2 on the PICK relay.
6. Manually compress/close the M and B contactors. This will apply a picking
voltage to the brake and it should lift.
a. For PM only: Go to MAIN MENU | DEBUG | ADJUST PARAMETERS and
record the value for 13-175, then change it to x00. This will allow the
Ebrake to stay picked until an emergency situation occurs.
Original Value: x______ New Value: x00
7. The car should drift up. If not the gearing of the machine may be low such
that it may have to be turned via a wrench with the brake lifted.
8. If car still doesn’t move try raising the car to the top landing and putting in
weights to overcome the counterweight.
9. As soon as the controller detects an out of Door Zone state with the doors
open the Controller will drop the Gripper.
10. Release the Brake or M and B Contactors.
11. If the doors did not close automatically, place the Car on Inspection MR and
go to MAIN MENU | SETUP | DOOR SETUP | MANUALLY OPEN AND CLOSE
and close the doors manually by moving the asterisk under the NUDGE
option and holding the ENTER key.
12. Remove all jumpers from the PICK relay.
a. For PM only: Restore the recorded value from step 6a back into 13-175.
13. Turn on DIP Switch #1 and press the Reset Button. The E-Brake fault may
require a power cycle to clear.
