Installation/commissioning
ƒ
The "safe torque off" function must only be installed and commissioned
by qualified personnel.
ƒ
All control components (switches, relays, PLC, ...) and the control cabinet
must meet the requirements of EN ISO 13849. These include for instance:
–
Switches, relays in enclosure IP54.
–
Control cabinet in enclosure IP54.
–
All other requirements can be found in EN ISO 13849.
ƒ
Wiring with insulated wire end ferrules is essential.
ƒ
All safety−relevant cables (e.g. control cable for the safety relay, feedback
contact) outside the control cabinet must be protected, e.g. in the cable
duct. It must be ensured that short circuits between the individual cables
cannot occur. For further measures, see EN ISO 13849.
ƒ
If force effects from outside (e.g. sagging of hanging loads) are to be
expected when the "safe torque off" function is active, additional
measures have to be taken (e.g. mechanical brakes).
During operation
ƒ
After installation, the operator must check the "safe torque off" function.
ƒ
The function check must be repeated at regular intervals, but no later
than after one year.
