DESCRIPTION

The 70 Series Brake is a direct acting, electro magnetically released, spring set unit that utilizes rotating and stationary

disc contact to supply positive braking action with quick release and setting capabilities at all times. Brakes which are

not provided with a floor mounting bracket are intended to be mounted as an integral part of electric motors listed for

corresponding hazardous locations where the acceptability of the combinations has been determined by Underwriter's

Laboratories, Inc. The explosion-proof assembly is completed by assembly of the brakes to the motors.

*If a hazardous location brake is purchased by other than an

authorized electric motor manufacturer, a Foot Mounted brake

must be purchased to obtain the UL label.

MANUAL RELEASE (See Figure 1)

To manually release brake, push in release knob and rotate

counterclockwise until strikes stop-pin. Brake will remain

released until release knob is pushed in and turned clockwise

or until power is restored, automatically resetting the brake.

THERMAL RELEASE

If the brake overheats, the thermal release mechanism will release

spring pressure on the friction discs, releasing brake. To reset ther-

mal release, allow brake to cool, then push in release knob (17)

and rotate clockwise until it strikes the stop-pin. Check brake

operation as overheating may indicate a broken lead wire or

burned out coil.

The thermal release mechanism has been calibrated at the factory

and the setting of the bimetal element and control rod MUST

NOT BE DISTURBED. If the mechanism does not function

properly, the complete pressure plate assembly (9), complete

magnet plate assembly (3), release gears (34) and items 31

through 50 must be returned to the factory for adjustments.
