Commissioning and operation
7.3
Regular technical inspections
Regular inspections must be conducted, as follows,
in order to ensure correct long term operation:
7.3.1 Regular examinations
At regular intervals, the operators must check the
non-contact safety switch T4000 Compact for
correct function
and
visible signs of tampering.
At appropriate intervals, it is also necessary to
check
the secure mounting of actuators and read heads,
(with the safety screws provided),
the sealing of the plug connector on the safety
switch,
the seating of loosened connections on the plug
connector
and
the switch-off distances.
The battery-free actuator requires no servicing and
ensures maintenance-free operation for the user.
7.3.2 Inspections by qualified safety
personnel
The inspection by qualified safety personnel must
be performed regularly as per the applicable
national and international regulations within the
intervals defined. This procedure ensures that any
changes on the machine or manipulations of the
protective device after commissioning are detected.
