Use of the mounting and wiring instructions
Target group: authorised and qualified staff.
All actions described in these instructions may only be performed by
qualified persons who have been trained and authorised by the
operating company.
1. Read and understand these mounting and wiring instructions.
2. Comply with the valid occupational safety and accident prevention
regulations.
3. Install and operate the device.
Selection and installation of devices and their integration in control
systems demand qualified knowledge of all the relevant laws, as well
as the normative requirements of the machine manufacturer.
In case of doubt, the German language version of these instructions
shall prevail.
Scope of delivery
1 device, 1 mounting and wiring instructions, carton.
Intended use
The device is used on machines and plants where an emergency-stop
command may be given anywhere along the pull-wire. Pulling or
breaking the pretensioned wire triggers the switching function of the
emergency pull-wire switch and thus lead to contact latching. The
reset can only be carried out manually by unlocking with the push-but-
ton. At least one switching element with a normally closed contact (NC
contact) must be used in the safety circuit. Observe country-specific
standards and directives. The requirements of EN ISO 13850 must also
be met before use.
Mounting and wiring
Mount the emergency pull-wire switches for one-side actuation
ZS 71 ... according to the instructions and pretense the wire accord-
ingly (see »Mounting without compensation spring«, »Mounting with
compensation spring«, »Configuration of switch cam«).
To detect correct mounting:
1. Remove enclosure cover.
2. Tense the wire so that the switch cam is in middle position
(position B).
Before mounting the pull-wire, remove the red PVC sheath from the
the pull-wire in the clamping range of the pull-wire (see »Mounting
notes wire thimbles«)! After fitting the wire, pull strongly on it several
times, as the pull-wire and the wire thimble will deform. Subsequently,
retense the wire using the DUPLEX wire clamp, eye-bolt or tensioner.
N.B.
The electrical connection may only be carried out by authorised per-
sonnel. Any mounting position is possible. Reconstruction and alter-
ations at the device - which might affect the safety function - are not
allowed. The described products were developed in order to assume
safety functions as 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 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 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.

Maintenance and troubleshooting

With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check pull-wire function.
2. Removal of dirt.
3. Check sealing of the cable or conduit connections.
Do not repair defective or damaged devices. Replace them. Alterna-
tive: Repair of defective device by trained personnel in agreement with
steute and with steute spare parts.
Cleaning
- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
