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.
Lasermet reserves the right to change the design, modify the operation of functions or add new
features at any time without prior notice.

3 Concept
The ICS-6-SP Control Unit forms part of a laser interlock system which is primarily intended to
protect persons from accidental exposure to hazardous lasers.
The Control Unit is intended to be installed in a control panel/cubicle and works in conjunction with
and is operated by a separate human-machine interface (HMI) panel such as Lasermet’s ICS-TOUCH
which provides an operator with a means to control and monitor the interlock system.
The ICS-6-SP Control Unit is able to monitor several doors, windows, curtains etc. fitted with safety
interlock switches and disable the laser if any are open. In this manual the term ‘Door Switch’ refers
to any interlock switch which may be fitted to a door, cover, window blind etc.
The versatile ICS-6-SP Control Unit can be connected to any number of door switches and can
indicate the status of up to four switches or groups of switches. An Arm Laser button is provided on
the touchscreen to arm the laser when all the safety requirements are met. An optional key lock or
keycode on the touchscreen prevents unauthorised use of the system.
The ICS-6-SP has a fully dual channel cross-checked architecture and when correctly wired can
realise a system compliant with EN ISO 13849-1 up to performance level ‘e’.
Three safety interlock outputs each rated at 6A resistive, 250Vac, are provided to enable the laser,
operate door locks etc. The interlock outputs are volt-free contacts which close when the system is
armed. Each contact actually comprises two contacts in series. In the event of one contact failing to
open, the other contact will open, and the system is then disabled, preventing further use and
maintaining safety. The contacts can be configured for a variety of options.
A separate changeover contact is provided for operating one or two-way illuminated warning signs.
The ICS-6-SP is able to monitor output devices such as contactors and shutters with feedback (such
as Lasermet’s LS-20 beam shutter) and the signs will display a danger indication in the event of a
monitored output device failing or partly failing to assume the safe state when the system is
disarmed.
The ICS-6-SP interlock controller is mounted on a DIN rail in a wall cabinet. This unit has inputs from
interlocks which must be in the safe state for laser operation, such as door switches, blinds and
emergency stop buttons. An output to the laser enables laser operation when all the interlock inputs
are satisfied.

ICS-TOUCH Instruction Manual
CEB00XXX-53-000 Page 7 of 43 Issue 4 19 January 2021
The ICS-6-SP is connected to the ICS-TOUCH panel by an RS232 serial data link. A 24V power supply
is also required. The ICS-TOUCH acts as a status display for the ICS-6-SP and allows the user to arm
and disarm the controller.
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 Summary of Evaluation of Compliance to EN ISO 13849-1:2015
To achieve a complete system performance level ‘e’ the system must be wired as described in this
manual using suitably rated door sensors and measures taken to minimise the effects of common
cause failures in the sensors and wiring which may be connected to the unit.
Achieved Characteristics:
Architecture Category 4
Performance Level (PL) PL = e
PFH [1/h] 2.47 x 10-8
(based on MTTFd being ‘capped’ at 100 years)
MTTFd 381 years
Mission Time 20 years
Diagnostic Coverage (DC) 99% (HIGH)

5 Installation
The ICS-6-SP Control Unit is designed to be attached to a 35mm ‘top-hat’ style DIN rail inside a
control cabinet. It should always be enclosed in a cabinet that requires use of a tool or key to open
to prevent tampering and risk of touching live connections. The unit should be installed such that the
length of cable needed to connect it to the user touchscreen is less than 1.5m.
Whilst the unit itself operates on 24V it is possible that higher voltages fed from other equipment
may be present on its output contacts.
The associated touch panel is fitted nearby (e.g. on a control panel) and is connected to the ICS-6-SP
Control Unit via a supplied RS-232 lead.
5.1 Positioning
The ICS-6-SP Control Unit should be mounted in a convenient position for wiring. It should be
inaccessible by operators. It has indicator lights on its top surface which would normally only need to
be observed by installation and maintenance personnel.
Provision should be made to prevent the unit from sliding along the DIN rail after fitting, for example
by the use of end clamps or other equipment.
During installation, wired connections will need to be made from the ICS-6-SP Control Unit to all the
interlocked doors, warning signs, laser interlocks, shutters and other equipment as required by the
system. Allowance should be made for wire retention such as plastic slotted trunking running
alongside both long sides of the unit.
All of the terminals are identified on the label on the top of the unit, see next page.

Nearest the edge of the label on a pink background are the
identifications of the bottom row terminals.
Next to these, on a green background are the identifications for the
top rows of terminals.
In the yellow box there are indication lights which light up when the
unit incoming power is on, expansion socket power is on and when the
two output channels are armed.

6 Wiring
ICS-6-SP Fail-safe Laser Interlock Controller
The ICS-6-SP Control Unit is a versatile interlock system and there are a variety of ways in which it
can be used. Be sure you know which configuration you require before you attempt to wire the unit.
If you require further assistance, please call Lasermet technical help. Contact details are at the end
of this manual.
A 2.5mm slotted screwdriver will be needed to access the screw terminals.
6.1 Power In
The ICS-6-SP requires 24VDC power. The power supply should be able to provide at least 1A for the
unit, plus any other equipment that may be run off the same supply such as 24V illuminated signs,
magnetic door locks (maglocks) etc.
Connect the power supply to terminal block ‘24VDC Power’ on the ICS-6-SP. Three terminals are
provided for +24V, any one of which may be used for the incoming power. The others are available
for feeding the touch panel and 24V equipment such as illuminated signs and maglocks. The same
applies for the 0V terminals.
6.2 ICS-6-SP Inputs
Mechanical Interlock Switches
Up to four door interlock switches may be directly wired to the ICS-6-SP. By making external
connections, more switches can be added and arranged in groups for indication purposes.
The interlock switches are wired to the terminals labelled Input 1 through to Input 4. Each interlock
switch should have two safety contacts which are closed when the door is closed. Some door
contacts such as Lasermet’s IS-MECH switches have an additional monitor contact which closes
when the door is opened. This is not used in ICS-6-SP.
