60 Series Hazardous

Brake Instructions

DESCRIPTION

The 60 Series Brake is a direct acting, electro magnetically released, spring set unit that utilizes rotating and stationary

disc contact to supply positive braking action and 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.

READ THIS BULLETIN CAREFULLY BEFORE INSTALLING OR OPERATING THE

60 SERIES BRAKE. FAILURE TO COMPLY WITH THESE INSTRUCTIONS CANCELS

ALL WARRANTIES SINCE THE SAFETY OF THE UNIT MAY BE ENDANGERED BY

IMPROPER INSTALLATION OR OPERATING PROCEDURES.

*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.

CAUTION

DO NOT OPERATE MANUAL RELEASE

OR ENERGIZE BRAKE COIL BEFORE

INSTALLATION IN ORDER TO PRESERVE

PRE-ALIGNMENT OF ROTATING DISCS

FOR EASE OF INSTALLATION.

USE ONLY HUB FURNISHED BY DINGS

SPECIFICALLY FOR USE IN HAZARDOUS

LOCATION BRAKES. DO NOT OPERATE

BRAKES IN EXPLOSIVE ATMOSPHERE

WITH COVER OR COVER BOLTS

REMOVED.

MANUAL RELEASE (See Figure 7)

To manually release brake, rotate release knob (41)

clockwise until it strikes stop-pin (39). Brake will remain

released until release knob is rotated counterclockwise, 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 thermal release, allow brake to cool, then

rotate release knob (41) counterclockwise 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 operator assembly

(44) must be returned to the factory for adjustment and

calibration.

WARNINGS A. Read this bulletin carefully before installing or operating the brakes. Failure to comply with the installation or operating instructions cancels all warranties and may cause injury to personnel and damage to property. B. DESCRIPTION The 60 and 70 Series brake for hazardous location is a direct acting, electromagnetically released, spring set brake that utilizes rotating and stationary disc contact to supply positive braking action.
PAGE 3
The thermal overload mechanism can be reset manually after a cooling off period. Before resetting, the cause for actuating the thermal overload mechanism should be removed. To minimize the possibility of overheating the brake to a point where the thermal overload mechanism will be actuated, the performance of the brake has to be matched to the requirements of the application.

WEAR ADJUSTMENT (See Figures 5 & 7) TORQUE ADJUSTMENT (See Figure 7) When armature plate (12) touches bracket (5), closing gap “B”, adjustment for friction disc wear is required. 13. Brake is factory set for rated torque. To increase stopping time and lower torque, turn locknuts (45) counterclockwise. Each full turn decreases torque by approximately 10%. FRICTION DISC REPLACEMENT (See Figure 7) 14. When total wear on rotating friction disc (2) reaches 1/16”, replace disc as follows.
PAGE 8
VERTICAL MOUNTING INSTALLATION AND ADJUSTMENT FRICTION DISC REPLACEMENT Installation and adjustment of the vertically mounted Dings Hazardous Location Brake is the same as on the standard 60 Series Hazardous Location Brake. When replacing friction discs, follow procedure outlined in paragraphs 14 and 15, with this addition: Care must be taken to insure proper insertion of the disc separating springs. Springs are color-coded for easy identification, and reference is made to spring color. See Figure 6.

TROUBLESHOOTING BRAKE DOES NOT RELEASE Check for broken lead wire, low voltage, and the power supply to brake. BRAKE DOES NOT STOP Check for worn or broken friction discs. Check brake hub to make certain it has not shifted on shaft. Check manual release. When brake coil is energized, release knob should move freely to reset position. Check thermal release. Release may have been activated. BRAKE CHATTERS OR HUMS Check magnet faces. They must be clean and parallel.
