Operating Instructions
Enabling Switch ZXE
This action can be achieved by releasing and
pressing again the enabling switch.
This automatic reset is important above all if an
enabling switch is to be used for an extended pe‑
riod. Often position 2 (enabling) is left only a little
due to fatigue of the operator’s hand or thumb. In
this situation, only one of the contacts signals a
release, the other remains in the enabling position.
The control system interprets this situation as
an enabling switch fault. Now it is helpful if it is
possible to continue working by simply releasing
and pressing again.
Should this not be possible, to some extent the
fault can also be automatically acknowledged by
the control system by means of the programming.
In any case, please ensure that release is detected
unambiguously first (both contacts in position 1
again) to rule out any faults in the wiring!
Functional check
WARNING
Danger of fatal injury as a result of faults in instal‑
lation and functional check.
f
Before carrying out the functional check, make
sure that there are no persons in the danger
zone.
f
Observe the valid accident prevention regula‑
tions.
Check the enabling switch by means of a functional
check (enabling function only in position 2). Check
that there is no enable function in position 2 after
reaching position 3 and releasing again.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
f
If damage or wear is found, the complete device
must be replaced. Replacement of individual
parts or assemblies is not permitted. The device
may be repaired only by the manufacturer.
f
Check the device for proper function at regular
intervals and after every fault.
Inspection of the following is necessary to ensure
trouble‑free long‑term operation:
f
correct switching function
f
damage, heavy contamination, dirt and wear
f
sealing of cable entry
f
loose cable connections or plug connectors.
