Monitoring the brakes
• The switching states and the wear of the brakes are monitored by means of dust-proof microswitches (see
connecting diagram).
• Please assure that the contact-current is at least 10 mA to keep the contacts clean.
Connection of the brakes
The brake coils, the brake control units and the monitoring contacts are connected to the mains in the
brake terminal box.
Warning
The microswitches must be evaluated separately for each partial brake to ensure compliance
with the requirements of the type examination.
