1.3.5. WARNING - The brake release buttons may be jammed after service work
Description
The brake release unit has push-buttons for the brake release of each axis motor. When
service work is performed inside the SMB recess that includes removal and refitting of the
brake release unit, the brake release buttons may be jammed after refitting.
DANGER!
If the power is turned on while a brake release button is jammed in depressed position, the
affected motor brake is released! This may cause serious personal injuries and damage to the
manipulator.
Elimination
To eliminate the danger after service work has been performed inside the SMB recess, follow
the procedure below.
Action
1. Make sure the power is turned off.
2. Remove the push-button guard, if necessary.
3. Check the push-buttons of the brake release unit by pressing them down, one by one.
Make sure none of the buttons are jammed in the tube.
4. If a button gets jammed in the depressed position, the alignment of the brake release
unit must be adjusted so that the buttons can move freely in their tubes!
