7.3 Testing the brakes
Prior to initial operation and with the monitoring system running, the work
stroke of the brake shoes must be checked.
When opening the brakes, ensure that both brake shoes are operating with
the same stroke.
Setting the brake shoe stroke:
With the solenoid actuated, the air gap between
brake disc and brake lining should be 0.3 mm
(see value cast on the brake shoe).
• Actuate brake magnet, check air gap with feeler
gauge.
• Correct the setting by twisting the nuts on the
setting screw at the brake shoe until the feeler
gauge set at 0.3 mm can be pushed through the
air gap at the same height of the arrow cast in
the brake shoes without resistance.
• Secure this setting by tightening the counter nut
and repeat this procedure at the second brake
shoe.
