Operation

6 Operation

6.1 Normal Operation

The COMBISTOP type 38 Theater Load Brake is an electrically activated spring set
brake. The brake is normally engaged with power off preventing rotation of the shaft.
When a nominal voltage is applied to the brake, the electromagnet disengages the brake
allowing free rotation of the shaft.
Operation of the brake is typically performed automatically through a customer supplied
control system. There is no manual operation of the Theater Load Brake unless the
optional Hand Release Lever is installed.

6.2 Manual Operation

With the optional Hand Release Lever, the brake may be disengaged manually by pulling
the lever directly away from the mounting surface to which the brake is attached. When
the lever is released, the brake engages once more preventing rotation of the shaft.
The Hand Release Lever is intended for emergency release of the brake in power failure
situations, and should not be used as the standard method of operation of the Theater
Load Brake.
