Emergency Brake Test - Unintended Motion, Rope Brake
This test verifies that moving the car away from a landing with both the car and Hoistway doors
open (termed “Unintended motion” will cause the Emergency Brake (Rope Gripper) to be
deployed and that such deployment will stop the elevator. This test demonstrates that the emer-
gency brake will stop the car within 48” from floor level if the car drifts from the floor.
Discrete Brakes - No Brake Module
1. For safety, station a mechanic at the landing where the test is to be performed.
2. Bring the car to the landing away from the terminals and place on Independent service.
3. Load the car as required (100% or 125% of load). Place barricades to prevent entry.
4. Use a non-metallic object to press and hold contactors, BK1 and BK2 (to allow the car to
drift from the floor).
5. As the car moves away from the floor, observe that the emergency brake stops and holds
the car within 48 inches (122 cm) of floor level.
6. To restore normal operation, verify doors are closed, place car on Inspection and press
the EB RESET button on the TC-MPI board for a minimum of 8 seconds until the emer-
gency brake resets.
When testing is complete, make sure that all appropriate data has been properly documented.
System with Brake Module
1. For safety, station a mechanic at the landing where the test is to be performed.
2. Bring the car to a landing away from the terminals and place on Independent service.
This will open the doors.
3. Load the car as required (100% or 125% of load). Place barricades to prevent entry.
4. Place the M-Brake Module on Manual mode by moving both dip switches 1 and 2 of
switch SW1 into the OFF position (see on page 3-44).
5. Press and hold both “BK 1" and “BK 2" contactors or use a non-metallic object to pick
and hold the contactors BK1 and BK2 to pick the brake. Manual brake pick voltage can
be adjusted through trim pot R67 (see on page 3-44).
6. As the car moves away from the floor, observe that the emergency brake stops and holds
the car within 48 inches (122 cm) of floor level.
7. To return brake module to normal operation, place SW1 #1 to ON position and SW1 #2
to OFF position.
8. Verify doors are closed, place car on Inspection and press the EB RESET button on the
TC-MPI board for a minimum of 8 seconds until the emergency brake resets.
9. Verify all appropriate data has been properly recorded.
