Category 5 testing of braking system
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 controller, stand positioned to observe movement of car (hoist ropes, drive sheave, cab)
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) Connect electric brake release box to the main brake. Electric brake release box will be used to
open main brake.
• If equipped with EBR: SWM key switch will be used to open main brake.
• Note: Open C01 connector and turn on UPS power to enable EBR.
