Category 5 testing of emergency brake
1) Elevator should 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.
3) Power the controller.

and open main brake using either the electric brake release box or EBR. A successful test is
when the elevator does not move.
• 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.
