Category 5 testing of braking system: Integrated Control Solution (ICS)
Main brake check
Perform this functional test prior to performing any tests with 125% load to verify brakes will
independently hold 125% load (150% load for Class C2 loading).
This test is not normally required as part of a safety inspection.
1) Run elevator to bottom floor and allow doors to open.
2) As soon as doors are open, put car on machine room inspection.
3) Load car with 125% load (150% load for Class C2 loading).
4) From MAP cabinet, stand positioned to observe speed and direction display and press one direction
button.
• A successful test is when the elevator does not move.
• Emergency brake should open and car should not move.
• If car cannot hold 125% load with main brake, brake must be checked and made to
hold 125% load before performing 125% down run test.
5) Proceed to check emergency brake if main brake passes test.
Emergency brake check
1) Elevator should still be on inspection and at bottom floor.
2)
Run elevator on inspection until car top is level with the top landing.
Access terminal block in SEP panel and switch main and emergency brake wiring at terminals MB+,
MB- and EB+, EB-.
3) Power the controller.
4)
From MAP cabinet, stand positioned to observe movement of car (hoist ropes, drive sheave, cab)
and open main brake using either the electric brake release box or EBR.
A successful test is when the elevator does not move.
Note: Main brake should open and car should not move.
If car cannot hold 125% load with emergency brake, brake must be checked and made to hold
125% load before performing any further tests.
5) If emergency brake passes check, return connections to original state.
Relevel test with 150% load for Freight elevators with Class C2 loading
Perform this test only on Freight elevators designed for Class C2 loading.
1) With elevator loaded with 150% load, manually open the brake and allow elevator to drift 1 - 2 inches
(25.4- 50.8 mm).
2) Release the brake and allow elevator to relevel.
3) Elevator must relevel the 150% load, and hold the load at floor level.
