Tab.12.1
To adjust the inductive proximity switch for brake pad wear, you can increase the airgap between
brake disc and brake pad on each side to a value of 0,6mm. Then fasten the inductive proximity
switch in a way that the LED is almost glowing. Then reduce the airgap to 0,2 ..0,4mm again.
Switch on the brake, the LED must not glow after the brake is in open position. Test the proper
function by switching the brake. The LED of the proximity switch must glow, if the brake status
you want to detect is reached.
