• Electrical function check
− Start machine
− Actuate operating element.
Check that the machine stops!
Check whether the machine stops when the EMERGENCY
STOP button is pressed.
4 Recurring technical checks
In order to guarantee faultless and durable function, the
following checks must be performed regularly:
• faultless function
• no recognisable manipulation
• secure fastening of the components
• leak tightness of the cable entries
• no loosened cable connections
5 Behaviour in the case of an error
Complete functional test after rectification of the error.
Carry out a complete functional test after the rectification of
