Not all component variants, which are possible according to this order
code, are available.
In accordance with the Machinery Directive, the type plate of
safety components is type plate labelled "Safety component".
Only if the information described in this operating instructions
manual are realised correctly, the safety function and
therefore the compliance with the Machinery Directive
and the Explosion Protection 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
The trapped key system, consisting of the components EX-SHGV...,
EX-SHGV/ESS..., EX-SVE.... and EX-SVM..., has been designed, in
conjunction with the control part of the machine, to prevent movable
safety guards from being opened before hazardous conditions have
been eliminated and may be used on machines and systems in areas
with a risk of explosion in accordance with the EX-marking. Installation
and maintenance requirements to the standard series EN 60079 must
be met.
By turning the key-operated selector switch from the trapped position
into the removable position, the NC contacts are positively opened and
the NO contacts closed.
This combination can only be used for applications, in
which the hazardous situation is eliminated without delay
(e.g. run-on movements) after the switch-off command
from the key-operated selector switch.
The trapped key system, consisting of the components EX-SHGV…,
EX-SHGV/ESS… and EX-SVM…, has been designed to prevent, in
conjunction with the control part of the machine, movable safety guards
from being opened before hazardous conditions have been eliminated.
If the control part of the machine transmits a signal to the EX-SVE…
that the hazardous situation has been eliminated, the key can be
withdrawn from the EX-SVE…, and as a result, the movable safety
guard can be opened.
If a delay device (e.g. timer) is used to by-pass the stopping
time, a failure of this device must not cause the delay time
to be reduced.
The user must evaluate and design the safety chain in accordance with
the relevant standards and on the required safety level.
The safety switchgears are classified according to ISO 14119
as type 2 interlocking devices.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
Please implement the necessary organisational measures to
ensure that only one main key is in use for each system.
The user imperatively must ensure that a key number (coding)
is only used just once in every plant (factory premises).

In position (1), the key(s) is/are trapped and cannot be withdrawn. The
NC contacts of the key-operated selector switch are closed. The NO
contacts are open. The NC contact of the magnet monitoring is closed
and the NO contact is open. If the magnet is in de-energised condition,
the keys cannot be turned and withdrawn. If the magnet is energised,
it will unlock the key-operated selector switch. The NC contact of the
magnet monitoring is opened and the NO contact closed. After the keys
are turned into position (2), they can be withdrawn. In this position, the
NC contacts of the key-operated selector switch are positively opened
and the NO contacts closed. In this key position, the solenoid cannot
switch to the "locked" position when the voltage supply is switched off.

Manual release (during set-up,maintenance, etc.) The manual release
is realised by turning the triangular key (included in delivery) to the right
(3), so that the solenoid is pulled into the release position. The normal
locking function is only restored after the triangular key has been
returned to its original position (4). The manual release must be sealed
after being put into operation (e.g. sealant etc.).
Key distribution station EX-SVM1…
In position (1), the primary key can be withdrawn. When the primary
key is removable, the secondary keys can only be in position (3) and
will be trapped (i.e. cannot be withdrawn). If the primary key is turned
into position (2), the secondary keys can be turned into position (4) and
be withdrawn. If one or more secondary keys are in position (4) either
removed, the primary key cannot be withdrawn. The primary key is
coming either from a EX-SHGV/ESS... key-operated selector switch or
a EX-SVE... key-operated selector switch interlocking device. Multiple
EX-SHGV… interlocking devices can be unlocked by means of the
secondary keys.

Conditions for safe operation
All devices and versions: The specified ambient temperature range
must be adhered to.
EX-SHGV/ESS… and EX-SVE…: Due to their specific impact energy,
the components must be fitted with a protection against mechanical
stresses. The command devices must be installed in housings that
meet the requirements of IP65 or higher in accordance with IEC 60529
and pass the tests according to IEC 60079-0 para. 26.4. The presence
of small dust particles inside of the dust-proof IP65 enclosure must be
excluded.

3. Mounting
3.1 General mounting instructions
Solenoid Interlock EX-SHGV
Four mounting holes are provided for fixing the interlock. 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).
The solenoid interlock must not be used as an end stop. Any mounting
position. The mounting position must be chosen so as to avoid the
penetration of dirt in the used holes.
In case of painting activities, the components must be covered. If
another actuating direction is desired, the four screws of the actuating
head must be loosened. Turn the actuating head in the desired direction
and retighten the screws (tightening torque 0.5 Nm). The default screws
installed in the actuating head can be replaced with the supplied
tamperproof screws. The actuator must be inserted when the actuating
head is turned.
Key-operated selector switch EX-SHGV/ESS…
Mount the key-operated selector switch in the provided mounting hole
Ø 22.3 by means of the mounting flange, align and tighten. (tightening
torque: 0.6 Nm). Snap the contact elements onto the mounting flange.
Check for a correct and firm fixation of the elements. Any mounting
position. The mounting position however must be chosen so that the
ingression of dirt and soiling in the lock barrel is avoided.
Key-operated selector switch-interlocking device EX-SVE…
Six mounting holes are provided for fixing the device. Screws must be
used that comply with ISO 7046 M4, A2 or A4 with a minimum length
of 8 mm (tightening torque 1.2 Nm). When used in applications with
function for the protection of man, the components must be fitted so
that disassembly is prevented. Any mounting position. The mounting
position however must be chosen so that the ingression of dirt and
soiling in the lock barrel is avoided. In case of painting activities, the
components must be covered.
Key distribution station EX-SVM…
Four mounting holes are provided for fixing the device. When used in
applications with function for the protection of man, the components
must be fitted so that disassembly is prevented. Any mounting position.
The mounting position however must be chosen so that the ingression
of dirt and soiling in the lock barrel is avoided. In case of painting
activities, the components must be covered.
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Correct fixing of all components
2. Check the integrity of the cable entry and connections.
3. Check all components for damage.
5.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:

2. Remove particles of dust and soiling.
3. Check cable entry and connections.
Adequate measures must be taken to ensure protection
against tampering either to prevent tampering of the safety
guard, for instance by means of replacement actuators.
Damaged or defective components must be replaced.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised
