Servicing and maintenance
Excellent and careful maintenance is a decisive factor for optimum
safety, functioning and performance and a longer service life of
the product.
DANGER
Maintenance work must always be performed by an electrician.
The maintenance personnel must read this operating manual
carefully. Work inside the control unit must be done by SCHUNK
Service personnel only.
This type of control unit has exclusively been designed to be in-
stalled inside the electrical cabinet of the machine tool and
doesn’t therefore require any specific maintenance.
However, we recommend checking the conditions of the connec-
tion cables to the mains and to the magnetic chucks on a monthly
basis.
Furthermore, the proper operation of the residual current device
upstream of the control unit has to be checked regularly, accord-
ing to the manufacturer’s recommended intervals and methods.
Please follow the a.m. instructions and maintenance intervals so as
to avoid repairs and resulting down-times, failures and inconven-
ience.
Defective electrical and electromechanical components must al-
ways be replaced by SCHUNK Service personnel. If components are
replaced by the operator, this automatically renders the warranty
void.
After maintenance and before reconnecting and restarting the
control unit, all protection devices must be reinstalled.
