Safety Instructions

• Installation, commissioning, modification and retrofitting must
only be performed by a qualified electrician.
• Disconnect the device/system from the power supply before
starting work. If installation or system errors occur, mains
voltage may be present at the control circuit in the case of
non-electrically isolated devices.
• When installing the equipment, please observe the
electrotechnical and professional trade association safety
regulations.
• Opening the case or manipulating the equipment in any other
way will render any warranties null and void.
• In the case of improper use or any use other than for the
intended purpose, the device must no longer be used and any
warranty claims shall be void. Exposure to the following
(amongst other things) is not permitted: significant mechanical
strain on the device (e.g. if the device is dropped); voltages,
currents, temperatures, humidity levels outside the
specifications.
• Always check all safety functions in accordance with the
applicable regulations during initial commissioning of your
machine/system, and observe the specified inspection cycles
for safety devices.
Caution!
• The application-specific standards must be observed when
installing and operating the device.
• The device must be installed in accordance with
IEC 60364-4-44.
• Take the following safety precautions before starting
installation/assembly or disassembly work:
1. Disconnect the device/system from the power supply before
starting work.
2. Secure the machine/system to prevent it being switched back
on.
3. Confirm that no voltage is present.
4. Earth the phases and short-circuit them briefly.
5. Cover and shield neighbouring live parts.
6. The devices must be installed in a switch cabinet with a
protection class of at least IP 54.
• Limited contact protection.
− Protection class according to EN 60529: IP 20.
− Finger-proof according to EN 50274.

1 Proper use
The device is used for monitoring control devices in
EMERGENCY STOP equipment. EMERGENCY STOP
equipment is part of the safety equipment for machinery,
which is installed in order to protect persons, material
and machinery. In the event of interruptions > t
device deactivates the enabling paths. Operation below
the minimum operating voltage (< 0.85 × U
in the enabling current paths being deactivated.
Only use the device in accordance with its intended
purpose. Pay particular attention to the information in the
technical data.
2 Function
Once the supply voltage (L1/L+) is applied to terminal A1
via the non-actuated EMERGENCY STOP button and to
terminal A2 via the neutral conductor (N/M), the reset
button between terminals Y1 and Y2 is used to activate
switch-on monitoring. This actuates relays K1 and K2.
Following the response time t
same time, switch-on monitoring is deactivated. Follow-
ing this switch-on phase, the two enabling current paths
(13/14 and 23/24) intended for the output are closed. An
LED assigned to the safety channels is used to indicate
these statuses. If the EMERGENCY STOP button is
pressed, the power supplies for relays K1 and K2 are
interrupted. The enabling current paths at the output are
opened.
Notes
• Before the reset button is activated, the EMERGENCY
STOP chain must be closed.
• The performance level (PL) and safety category in
accordance with EN ISO 13849-1 depend on the
external wiring, the application case, the choice of
control device and how this is physically arranged on
the machine.
• The user must carry out a risk assessment in
accordance with EN ISO 14121-1.
