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
The TESK hinge safety switch has been designed to prevent, in con-
junction with the control part of a machine, movable safety guards from
being opened before hazardous conditions have been eliminated. They
are also suitable for fitting on profile sections and existing equipment.
Hinge safety switches can only be used for applications, in
which the hazardous condition is terminated without delay
(e.g. run-on movements) when the safety guard is opened.
The user must evaluate and design the safety chain in
accordance with the relevant standards and on the required
safety level.
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
Four elongated holes are provided for fixing the switch. To facilitate the
alignment of the door to the post, alignment pins are supplied (not for
indoor use) that can be inserted into corresponding holes on the bottom
of the hinge switch (Fig. 2). Once installed, these can be removed
again.
Fig. 2
When used in applications with function for the protection of man, the
components must be fitted so that disassembly is prevented (e.g. drill
out the hexagonal recess of the fixing screws, blocking the hexagonal
recess using a plastic cone diameter 5.1 mm).
The hinge switch furthermore must be pinned after assembly and
adjustment (Fig. 3).
A) A)
Fig. 3
Legend:
A = Drill and pin in this area
The hinge safety switch must not be used as an end stop.
Any mounting position. The mounting position however is chosen so
that the components are preferably fitted in the upper part of the safety
guard to avoid the ingress of dirt and soiling as well as damage to the
components. In case of painting activities, the components must be
covered. Recommended mounting material, see technical data.
We recommend that the fixing screws are painted after the component
is fitted and to apply the accompanying caps (Figure 4.)
The minimum bending radius must be observed for versions
with a cable connection!
Please note the load information "Determining the permissi-
ble forces as a function of door size and number of hinges"
(see Section 7.3 Load details)
The hinge safety switch must not be used as an end stop.
With applications where heavy doors are used and especially
when they cannot close easily or without any retardation,
additionally measures need to be taken to prevent loosening
of the mounting screws.
Fig. 4
Please observe the remarks of the standards EN ISO 12100,
EN 953 and EN 14119. Also observe the safety distances to
the standards EN ISO 13857 and EN 349.

3.2 Adjustment and inspection of the switching angle
After the switch has been fitted, the switching function and the opening
angle of the safety guard must be checked. The switching angle of the
NC contacts set in factory is approximately 3°.
Caution: for the TESK...-U version, the following paragraph
"Special instructions for the on-site setting" imperatively must
be observed!
Special instructions for the on-site setting (version TESK...-U)
We recommend a setting including the following steps:
1. Open the safety guard up to the maximum authorised opening angle.
2. Use the adjustment tool to set the NC contacts so that their opening
is ensured at the maximum authorised safety guard opening angle.
Turn clockwise to decrease the switching angle, turn counterclock-
wise to increase the switching angle (Fig. 6); when mounted inside
accordingly reversed.The positive break angle is 7° larger than the
set switching angle.
3. After the switch is set, the compliance of the switch with the safety-
technical requirements of the application must be checked. (See
Section 7.2 Door gap calculation)
4. After the switching angle has been set and checked, the blanking
plug for the adjustment opening located at the rear of the adjustment
tool must be inserted in the adjustment opening (1) and torn down by
making lateral movements (2) with the tool (Fig. 7).
-
+

Fig. 6 Fig. 7
After the desired switching point is set, the opening of the
setting option imperatively must be sealed with a blanking plug.
This measure prevents tampering at the set switching point
within the meaning of EN 14119 paragraph 5.7 and therefore
avoids any loss of the safety function of the device.
The blanking plug is injected to the special adjustment tool with
a predetermined breaking point.
We recommend an additional painting or glueing of the blan-
king plug.
Securing the setting screw by means of the blanking plug is a
mandatory instruction for the user, which must be oberved in
order to maintain the CE-Conformity of the component.

Example:
A door made of 40 mm aluminium profile with a length of 950 mm
should be secured with a TESK. The safety contact of the TESK opens
to 3° when new according to the technical safety sheet (10° at the end
of its service life). The table above shows the door gap when new at ap-
prox. 49.7 mm. The real door gap can be calculated with the following
equation D1 = D – B; (49.7 – 40 = 9.7); D1 = 9.7 mm. At the end of the
service life the door gap is approx. 164.9 mm and the real door gap is
(164.9 – 40 = 124.9); D1 = 124.9 mm.

C = Use of one hinge switch and an additional hinge
D = Use of one hinge switch and two additional hinges
With larger doors the have three hinges make sure the two of
the hinges are located in the upper third.
We recommend that the hinge switch is placed in the middle
when three hinges are used.
The hinge safety switch must not be used as an end stop.
With applications where heavy doors are used and especially
when they cannot close easily or without any retardation,
additionally measures need to be taken to prevent loosening
of the mounting screws.
