The device complies with the European standards for explosion protec-
tion EN 60079-0, EN 60079-1 and EN 60079-31. It is intended for use in
hazardous areas of zones 1 and 2 as well as zones 21 and 22 according
to EN 60079-14. Comply with the requirements of EN 60079-14, e.g.
with regard to dust deposits and temperature limits. The device is used
in safety circuits to monitor the position of mobile safety guards to
EN ISO 14119 (EN 1088) type 1 and EN 60947-5-1.
Special conditions and »X« marking
- The cable of the device must have a fixed installation and be set up in
a manner that protects it from mechanical damages.
- If the connection is within a hazardous area, the connection cable has
to be connected in an enclosure which complies with the require-
ments of an approved type of protection according to EN 60079-0,
par. 1.
- The capacity of the guide bush and of the operating plunger is
4.5 ± 0.5 pF. To use the device in gas group IIC, there must be a 4 mm
distance between the guide bush and surrounding metal parts.
Installation, mounting, dismantling
=
DANGER
Live parts and explosive atmosphere. Electric
shock hazard! Explosion hazard! Before commis-
sioning, check device for correct installation. Com-
ply with national regulations.
=
DANGER
Live parts. Explosive atmosphere. Electric shock
hazard! Risk of burns! Connecting and disconnect-
ing only to be performed by qualified and author-
ised personnel. Connecting and disconnecting only
in non-explosive environment.
Mount the device on an even surface. Ensure that the device cannot
be moved from its position. Ensure this in case of failure, too. When
mounting the actuator and switch, observe the requirements of
EN ISO 14119, especially paragraphs 5.1 to 5.7! For protection against
unauthorized manipulation, use e.g. one way safety screws. These are
optionally available. 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 fuse size 6 A (gG/gN).
- 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
=
DANGER
Live parts. Electric shock hazard! When cleaning:
observe degree of protection IP65.
- Use a damp cloth to clean devices in 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. Explosion hazard! Risk of
burns! Do not rebuild or modify the device in
any way.
With rough conditions, we recommend routine maintenance as follows:
1. Check actuator for easy operation.
2. Removal of dirt.
3. Check sealing of the cable or conduit connections.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
N.B.
Do not use the device as mechanical endstop. Any mounting position
is possible. Furthermore, EN 60079-14 has to be applied for the instal-
lation of electrical equipment in hazardous areas. Moreover, the ATEX
test certificate and the special conditions therein have to be observed.
The described products were developed in order to assume safety
functions as part of an entire plant or machine. A complete safety sys-
tem normally covers sensors, monitoring modules, indicator switches
and concepts for safe disconnection. For the integration of the device
in the entire system: strictly observe and respect the control category
determined in the risk assessment. Therefore, a validation according
to EN ISO 13849-2 or EN 62061 is necessary. Furthermore, the Perfor-
mance Level according to EN ISO 13849-1 and SIL CL Level according
to EN 62061 can be lower than the single level because of the combi-
nation of several safety components and other safety-related devices,
e.g. by serial connection of sensors. It is the responsibility of the
manufacturer of a plant or machine to guarantee the correct general
function. Subject to technical modifications.
