Leveling Overspeed Test
This test verifies that the leveling zone does not exceed the maximum allowable distance and
that the leveling speed does not exceed 150 ft/min (0.75 m/s). (NOTE: Be sure to make note of
the original parameter values so they can be restored after the test):
1. On the Configuration > Drive > General tab, set Emergency rate limited stop = 25 ft/s
2
.
2. On the Setup > Safety > Configuration tab, set Leveling overspeed = 7 fpm and click
Send. Then perform the Learn operation.
3. On the Configuration > Pattern > Common tab, set Leveling distance = 4 in, set Level-
ing speed = 9 fpm, and click Send.
4. Place a call to any landing. Verify that when the car enters the leveling zone, the system
detects a Safety A (or B) Inspection Leveling Overspeed Fault and performs an emer-
gency stop. Following the emergency stop the car should level into the floor, if neces-
sary. (NOTE: If the car is unable to relevel into the floor and the fault is generated 5
times, the fault will become persistent and the iBox Fault Reset button must be pressed
to reset the fault. It may be necessary to restore the parameters that were changed in
steps 1 through 3 in order for the car to relevel to the floor.)
5. Restore the parameters that were changed in steps 1 through 3 to their original values.
Emergency Brake Test - Unintended Motion
The Emergency Brake test allows the car to leave the floor with doors open. Station personnel or use
a positive means to make certain there is NO ONE in the car.
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 (e.g., Rope Gripper) to be
deployed and that such deployment will stop the elevator. No test Speed input is required for
this test.
1. Select the Emergency Brake Test - Unintended Motion.
2. Follow on-screen instructions.
