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
- Position the device protected from shock loads.
- 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 in an explosive area, the cable has to be connect-
ed in an enclosure which complies with the requirements of an ap-
proved ignition protection degree 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 dis-
tance between the guide bush and surrounding metal parts.
Installation, mounting and dismantling
=
DANGER
Live parts. Explosive atmosphere. Electric shock
hazard! Explosion hazard! Before commissioning,
check device for correct installation. Comply 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 atmospheres.
Mount the device on an even surface. Any mounting position is pos-
sible. Ensure that the device cannot be moved from its position. En-
sure this in case of failure, too. For protection against unauthorised
manipulation, use e.g. one-way safety screws. These are optionally
available. When mounting the device, observe the requirements of EN
14119, especially the sections 5.1 to 5.4! Observe the instructions in
the standards EN ISO 12100 and EN ISO 14120.
Application and operation
- Use device only within the permitted electrical load limits (see
technical data).
- For short-circuit protection use fuse size 6 A (gG/gN).
- 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 explosive 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.
Maintenance, repair and service
=
DANGER
Live parts. Explosive atmosphere. Electric shock
hazard! Explosion hazard! Risk of burns! Do not
repair defective or damaged devices. Replace them.
Do not rebuild or modify the device in any way.
With rough conditions, we recommend routine maintenance as follows:
- Check actuator for easy operation.
- Remove all dirt or particles.
- 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 a mechanical endstop. Reconstruction and
alterations at the device - which might affect the explosion protection
- are not allowed. Furthermore, EN 60079-14 has to be applied for the
installation of electrical equipment in explosive areas. Moreover, the
ATEX test certificate and the enclosed special conditions have to be ob-
served. The device has been developed in order to assure safety func-
tions as a part of an entire plant or machine. A complete safety system
normally covers sensors, monitoring modules, indicator switches and
concepts for safe disconnection. For the integration of the device into
the entire system, the control category determined in the risk assess-
ment must be strictly observed and respected. Therefore, a validation
according to EN ISO 13849-2 or EN 62061 is necessary. Furthermore,
the Performance 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 combination of several safety components and other safety-relat-
ed 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. steute does not
assume any liability for recommendations made or implied by this
description. New claims for guarantee, warranty or liability cannot be
derived from this document beyond the general terms and conditions
of delivery.
