2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
ZQ 700- ➀
No. Option Description
➀
11 1 NO/1 NC contacts
02 2 NC
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefore
the compliance with the Machinery Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
Pull-wire emergency stop switches are used on machinery and plants,
where triggering the emergency stop command must be enabled at
arbitrary points on the wire run. If the tensioned pull-wire is pulled
or in case of wire breakage, the switching function of the pull-wire
emergency stop switch is activated. (refer to image 1)

Image 1: position indication and actuation
Design/operating principle
The pull-wire emergency stop switches of the ZQ 700 series are
brought into the operational condition by the proper pre-tensioning of a
maximum 10 m long wire. The inner switching element has 2 contacts;
in a tensioned condition, the NC contacts are closed and the NO
contacts are open.
After actuation of the emergency stop function, a latching mechanism
maintains the stop command until the switch is released by pushing the
blue reset button.
Prior to the reset of the emergency stop signal, the reason why the
switch has been actuated must be determined. The switch can only
be reset if the switch is correctly pre-tensioned (position indication in
central position, refer to image 1).
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.

3. Mounting
3.1 General mounting instructions
The installation may only be carried out by authorised personnel. The
pull-wire emergency stop switch is fitted by means of four screws
(distance of the drill holes 30 mm or 60 mm), so that a release by hand
can be enabled without hazard. The component must be fitted so that
the entire length of the wire can be viewed from the position of the
switch.
In accordance with IEC 60947-5-5, the maximum perpendicular
traction force to be exercised on the wire in order to activate the
emergency pull-wire switch is 200 N, the maximum deflection is
400 mm. Sufficient space must be provided so that the required
actuating deflection can be reached.

3.2 Mounting set-up
For tensioned span lengths up to 10 m, intermediate wire supports
are required every 2 to 5 m. To avoid resonance vibrations in the wire
on machines with high vibrations, it is recommended to realise the
individual support length differently. Assembly: refer to image 2.

We recommend the use of the ACC-700-RZ173 tension spring to
reduce the effects of temperature variations. Due to the thermal
expansion behaviour of the wire, the maximum authorised wire length
is determined by the ambient temperature range (refer to image 3).

The pull-wire must be fixed to the ring and then be pre-tensioned until
the position indication is in the central position (refer to image 1).
As the thimbles are subject to deformation in case of wire pull, the wire
should be pulled several times after fitting. After that, the wire must be
re-tensioned (see image 4).
Image 4: deformation of the wire thimbles
In order to ensure an optimal operation safety and to save
time during fitting, we recommend using the wire rope and
the combined fixing and tensioning system from Schmersal.
Alternatively, wire thimbles and wire clamps can be used
in conjunction with a tensioner. In this case, the red PVC
sheet must be removed in the clamp area prior to installing
the wire rope.

4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by authorised
personnel in a de-energised condition.
1. Cover screws must be loosened
2. Dust shield cap remove
3. Cable glands M20 x 1.5 with an appropriate degree of protection
must be used
4. When wiring, please ensure that no cables are located within the
range of the lever system and the pushbutton
5. The inside of the switch must be imperatively cleaned (e.g. removal
of cable residues), considering that foreign bodies can affect the
switching behaviour
6. The cover screws must be tightened uniformly (tightening torque 0.5 Nm)
The switch with plastic enclosure is double insulated. The use of an
earth wire is not authorised.
