Microswitch (CO4)

NOTICE

Microswitch

The microswitch is not a safety-related component and is not covered by the safety case.

The brake can be equipped with a microswitch to monitor its release. The microswitch can be

integrated in the circuit as an NC or NO contact.

The user must provide the electrical connection that is appropriate for the microswitch

option.

Possible application of the brake release monitoring:

The motor does not start up until the brake has been fully released. This means that the

microswitch can monitor all faults that occur, for example, when the motor does not start if

the rectifier is defective, interrupted connecting cable, defective solenoid or excessively large

air gap.

Encapsulated brake (CO1) / encapsulated brake with condensation drain hole (C11)

LS safety-related brakes can be supplied as encapsulated brakes. In this case, a dust

protection ring is installed around the circumference of the brake and a shaft sealing ring

at the shaft outlet.

This prevents the release and penetration of dust, moisture and dirt. Other advantages

include reduced noise when applying the brake as well as, in combination with a motor

anti-condensation heater, a reduced risk of the rotor freezing on the friction surfaces.

In addition, a condensation drain hole can be incorporated in the dust protection ring for

brakes. The encapsulated brake is also available in combination with a manual brake release

lever and a manual brake release lever with locking mechanism.
