One-sided Brake Test: MX10 and MX20
Procedure Note
1. Position the empty car so that the blocking
pin of car blocking device is at the bottom of
the slot in the blocking plate.
2. Engage the car blocking device.
3. Mark the position of the traction sheave
(brake drum) on the motor body.
4. Open the brake fully using the MX Electrical
brake opening tool. (Move toggle switch (6) on
tool (1) to ON to open the brake.)
WARNING! Open only one brake at a time!
WARNING! If the brake release cable is too
tight, when one brake is opened, there is a risk
of opening simultaneously the other brake!
WARNING! Before removing electrical covers,
ensure that the power is switched OFF.
5. Wait for a minute.
Check for movement of the safety pin in the
slot of the blocking plate.
If the brake test fails (the car moves until the
safety pin hits the top of the slot), initiate
corrective measures. The brake system must
pass the test before the elevator is put back
in service.
Leave the elevator out of service until the
brakes are operating properly and the brake
test is passed!
6. Close the brake using the MX Electrical brake
opening tool.
(Move the toggle switch (6) on tool (1) to OFF
to close the brake.)
