2 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

3 Concept
Lasermet’s Active Laser Window, called Glaser Jailer, detects a laser beam striking the window
surface and causes the laser beam to be turned off.
The system uses an inherently fail-safe laser detecting sensor panel. This is sandwiched between the
glass layers. The sensor is electrically connected to a monitoring and detection circuit board which is
fitted inside a Lasermet Interlock Control System (ICS). In addition, a passive protection layer is
provided.
The ICS-6 monitors the Active Window circuitry and other interlocked devices. The ICS-6 is
connected to the interlock connector on the laser to disable the laser beam if there is an inadvertent
laser strike on the window.
Because of the inherently fail-safe detection technique used, any failure of the sensor will also
disable the laser. There are no maximum or minimum beam diameter requirements and no
maximum or minimum laser power limits (very low power densities may not cause the system to trip
but they will also be too low to cause any damage to the sensor or pass through the passive
protection layer).
When the Active Window system is tripped, the monitoring and detection circuit latches off. The
window must be replaced, and the system manually reset in order to re-arm the system.
Every effort should be made in the first instance to reduce the risk of a laser beam striking the walls
or window. Careful alignment and setting-up should always be made prior to enabling the beam.

CEB00XXX-53-000 Page 7 of 12 Issue 7 19 January 2021
The Active Window system can disable a multi-kilowatt laser before the passive protection layer
fails. The function of the passive protection layer is to contain the laser beam for long enough to
allow the laser to be shut down. The Protection Time quoted in the Protective Exposure Limit (PEL)
specification is the minimum time for which the Window will contain the laser beam, at the quoted
PEL, after the control system has issued the shutdown command. The user must ensure that the
laser beam emission can be shut down within this time.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.
4 Wiring
The Active Window has four connections to the ICS-6 via the plug-in Active Window Interface Card.
These connect to the start and end of two conductive tracks on the window’s sensor panel. The
terminal blocks on the Active Window Interface Card are marked A and B to indicate the separate
circuits. The two circuits are interchangeable.
The Active Window is terminated in a 1m 4-core lead which is wired to the Active Window Interface
Card, via terminals, by the installer. The connections are as follows:

5 Operation
Turn on the ICS power switch.
When all the relevant interlocked doors are closed the system may be armed, as follows:
ICS-6
Press the ‘Arm Laser’ button on the front of the ICS-6. The ICS-6 will briefly test the operation of the
active window interface by applying a simulated fault. If the associated safety relays do not open at
this point, the laser will not arm. If the relays open correctly, the test will cease and the simulated
fault will be removed. The ‘Laser Armed’ light will illuminate to indicate that the system is armed.

CEB00XXX-53-000 Page 8 of 12 Issue 7 19 January 2021
5.1 Laser Detection
If a powerful laser beam strikes the Active Window, the detection system in the interlock controller
will shut off the laser beam. The ‘hit’ is recorded by a Fault latch. The setting of this latch is indicated
on the front panel of the ICS, as follows:
ICS-6
A yellow light is illuminated next to the legend ‘Expansion’.
If this happens the system needs to be investigated and repaired prior to release of the fault latch.
Although it may be possible (though unlikely) to arm the laser after a laser strike to the window, it is
strongly recommended that a damaged window is repaired or replaced prior to any use of the laser.

Note that the Active Guard Protection time is the time the window will contain the laser beam after
the Interlock Control System has issued the shutdown signal. Therefore, the laser must cease output
within 0.5 s of receiving the signal from the Lasermet Interlock Controller.
EN 13849-1 Performance Level
When included in ICS-6, the Active Window subsystem meets EN13849 PLe.

6.2 Dimensions
The active protection is effective only on the window area and not on the mounting flange. The
window is mounted with the flange on the outside of the laser enclosure.
Dimensions are approximate. Values given as ‘typical’ are average values measured across a number
of samples and are not guaranteed. Lasermet reserve the right to alter any specification without
prior notice.
