Safety interlocking switch with solenoid lock
Intended use
PSEN me1 safety switches are interlocking devices equipped with a solenoid operated guard lock. When used together with a suitable machine
control system these switches also monitor the position of movable guards. When correctly installed the PSEN me1 ensures that movable machine
guards can only be opened when it is safe to do so. Machine start-up, which could cause hazardous situations, is only possible if the movable
machine guards are duly closed and the PSEN me1 locking device is latched in position.
Standards governing installation and operation: EN 954-1 safety-related parts of control systems
EN 1088 interlocking devices with and without movable machinery guards
EN 60 204-1 electrical equipment of industrial machinery
Risk assessment at the machine acc. to: EN 954-1 safety-related parts of control systems
EN 1050 safety of machinery, risk assessment
The mounting position is flexible, however the position should: 1- Allow authorized personnel to access the manual lock over-ride in order to control
and, if necess ary, exchange components. 2- Ensure that for eign objects c annot enter the ac tuator opening whilst the guard is open.

Excess of the maximum torque of 0.9 Nm or installing the actuator so that it is subject to lateral forces may
damage the actuating mechanism of the switch gear. This can render the personal protection function useless
and cause serious injury or accidental death. Never use the safety switch and actuator as an end stop!

Locking principle : Spring lock (without power)
The safety guard is automatically locked when the actuator is correctly inserted. Supplying power to the solenoid unlocks the protective system
and the safety guard can then be opened.

Locking principle : magnetic force (With power applied)
The locking device is only activated when power is applied to the solenoid. NB. If there is a power failure or there is a trigger error, the safety guard
can be opened.

System descrip t ion / Suggested applicat ion
When the machine guard is closed, the actuator is engaged and locked in the safety switch. In this state the safety outputs in
the safety control module are closed and the contact in the control module (for the solenoid) is open - the machine can now
operate.
In order to carry out maintenance work behind the safety guard the operator has to switch off the machine. This will cause
opening of the outputs of the control module and shutoff of the machines power line. As the dangerous movement of the
machine may not stop immediately, the safety switch lock should only release the actuator after the machine has come to a
complete stop. A suitable control module, e.g. a lost-motion monitor or a delay module (safety timer) can be used for that
purpose.
The safety contacts (force disconnected N.C.) inhibit the machine from restarting whilst the machine guard is open. The
additional N.O. contacts can be used as signaling contacts, they do not have a safety function and are normally used for
indication only. These functions do not conduce safety, just availability of machinery. When used in conjunction with suitable
control modules the NO contacts may be used only for additional
The set of contacts monitoring the safety guard is form-fit driven by the actuator, so that the position of the safety guard is
directly monitored. The set of contacts monitoring the locking device has a positive drive connection to the lock. Thus ensures
that any failure of the locking device will be immediately detected by the safety control system. An integrated mechanical
mechanism ensures that the lock cannot be engaged whilst the actuator is removed from the safety switch.
The safety switch PSEN me1 can be applied in combination with other safety switching devices and safety control modules in
systems up to control category 4 acc. to DIN EN 954-1 when the applicable standards are maintained.

Maintenance / Inspection

operation and a long s ervice life
the device should be inspected
regularly. Ensure that:
- all components are s ecure and tight
- switching functions operat e properly
- all sealing gaskets are in proper
condition
- the components show no signs
of tear and wear.
If defects are the detected the
complete switching device and the
actuator have to be replac ed.
