9.2 Brake monitoring circuit

The brake monitoring circuit checks the brake shoes.

It prevents motor movements when the brake is partially or fully closed and
enables detection of any brake lining wear at an early stage.

Switches (sensors SA3 or microswitches SA3.1/SA15) are used to check
whether the brake shoes are closed, open, or worn.

The travel signal - derived from the W/W1 contactor - is used for the evaluation.

It is indicated by means of light emitting diodes

on the sensors (SA3 only).

on the brake monitoring in the control cabinet and/or by deactivation of the
drive.
If a Teleservice device is connected, the fault is shown on the display.
