NOTICE DAMAGE TO THE DEVICE OR MOTOR IF NOT AVOIDED
IF THE BRAKE DOES NOT RELEASE DUE TO A FAILURE, THE
SAFETY FUNCTION COULD BE LOST DUE TO WEAR OR
DAMAGE TO THE BRAKE.
THE FAILURE “BRAKE DOES NOT RELEASE” MUST BE TAKEN
INTO ACCOUNT DURING THE DESIGN OF THE BRAKE(S) AND THE
VALIDATION.
THE FAILURE “BRAKE DOES NOT ENGAGE” MUST BE EXCLU-
DED BY ONE OF THE FOLLOWING MEASURES:
ƒ
Usage of a safety brake with a manufacturer's specification that
excludes this failure with the necessary safety integrity.
ƒ
Definition and validation of a second means of braking in the ap -
plication. For instance this feature can be achieved by using two
brakes where each brake is in itself capable of applying the neces-
sary braking torque. In addition, the function of the brakes must be
validated regularl
y
.
INFO
If the function SBC is not used, as of hardware revision A2 the test
pulses on the brake output are switched off.
