The signal words have the following meanings:
NOTICE
indicates a situation which may
result in material damage.
CAUTION
indicates a situation which may
result in minor or moderate
injury.
WARNING
indicates a situation which may
result in serious injury or death.
DANGER
indicates a situation which will
result in serious injury or death.
Intended use
=
DANGER
Misuse and explosive environment.
Explosion
hazard! Risk of burns!
Not for use in categories 1
and 2/zones 0 and 1 and zones 20 and 21. Use only
in permitted categories/zones. Use device only in
accordance with the operating conditions defined
in the mounting and wiring instructions. Use device
only in accordance with the intended purpose de-
fined in the mounting and wiring instructions.
The device complies with the European standards for explosion protec-
tion EN 60079-0 and EN 60079-18. It is intended for use in explosive
hazardous areas of zones 2 and 22 according to EN 60079-14. Comply
with the requirements of EN 60079-14, e.g. with regard to dust depos-
its and temperature limits. The device is used in safety circuits to mon-
itor the position of mobile safety guards to EN ISO 14119 (EN 1088)
type 4 and EN 60947-5-3. The EN 60947-5-3 standard is only met if the
entire system consisting of the safety sensor, the actuator and a
safety module.
Installation, mounting, dismantling
=
DANGER
Live parts. Explosive atmosphere.
Explosion haz-
ard! Risk of burns!
Connecting and disconnecting
only to be performed by qualified and authorised
personnel. Connecting and disconnecting only in
non-explosive environment.
Mount the sensor and the actuator on an even surface and opposite
each other according to the marks on the sensor and actuator. The
electrical connection may only be carried out by authorised personnel.
Due to the danger of manipulation: Prevent accessibility to actuators
and spare actuators. Ensure that the device cannot be moved from its
position. Ensure this in case of failure, too.
When mounting actuator
and sensor please observe the requirements of EN ISO 14119, espe-
cially paragraph 7, »Construction to reduce manipulation of interlock-
ing devices«!
For protection against manipulation use one-way safety
screws, Torx with pin, riveting, etc. Sensor and actuator should not be
fixed on ferro-magnetic material, this leads to strong changes of the
switching distances. Do not install the sensor and the actuator in
strong magnetic fields. Keep away ferromagnetic cuttings. Do not ex-
pose the device to extreme vibrations and shocks. A mounting distance
of min. 50 mm between two systems must be observed. Observe the
instructions in the standards EN ISO 12100 and EN ISO 14120.
Application and operation
=
DANGER
In case of overloaded contacts too high operation
temperatures.
Explosion hazard! Risk of burns!
For
short-circuit protection use appropriate fuse size.
- Use device only within the permitted electrical load limits (see
technical data).
- Use device only within the permitted ambient temperature range
(see product label and technical data).
Cleaning
- Use a damp cloth to clean devices in explosive hazardous areas. This
prevents electrostatic charge.
- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Service, maintenance, repair
=
DANGER
Live parts.
Electric shock hazard!
Do not repair de-
fective or damaged devices. Replace them.
=
DANGER
Explosive atmosphere.
Risk of burns!
Do not re-
build or modify the device in any way.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a regular maintenance as follows:
1. Check switching function.
2. Check for tight installation of the sensor and coded actuator.
3. Removal of dirt.
Special conditions and »X« marking
- Each device must be switched upstream with a fuse corresponding to
its switching current in accordance with IEC 60127-1-2. The fuse may
be installed in the corresponding supply device or must be switched
separately. The rated fuse voltage must be equal to or higher than
the maximum switching voltage of the device.
- The maximum prospective short-circuit current at the location of in-
stallation may not exceed 50 A.
- The cable of the device must be routed fixed such that it is sufficiently
protected against mechanical damage.
- Connect the cable of the device in an area which is not subject to po-
tential explosive. If the connection is carried out in an explosive haz-
ardous area: connect the cable in an enclosure that complies with
the requirements of a recognised ignition protection type according
to EN 60079-0.
