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
The ICS-6-OEM provides control of an interlock system primarily intended to protect persons from
accidental exposure to hazardous lasers. It 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-OEM system can be connected to any number of door switches and can indicate
the status of up to 6 switches or groups of switches.
Two external volt-free contacts are required to arm the system. These might be from a PLC, for
example. When these contacts are both closed, provided the necessary interlock input conditions
are met (e.g. doors closed), the Controller will arm and enable the laser. If the Arm contacts are then
opened the system will disarm.
If any interlock input (e.g. door) is open when the external Arm contacts are closed the controller
will not arm. If the interlock is then closed the controller will still not arm. This is to prevent an
unexpected start-up of the laser. To arm the controller in this case the external Arm contacts must
be opened and reclosed once the interlock has been closed.
The ICS-6-OEM 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’.
Seven safety interlock outputs each rated at 4A resistive, 50VDC, are provided to enable the laser,
operate door locks, provide signals to a PLC 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 when the controller disarms, 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.
The ICS-6-OEM is able to directly control and monitor safety-rated power contactors which may be
used to switch single or three-phase laser mains supplies.
The ICS-6-OEM is able to monitor output devices such as shutters with feedback (such as Lasermet’s
LS-20 and LS-200 beam shutters).
The controller has a pair of isolated volt-free contacts which close in the disarmed state provided all
monitored devices are proven to be in the safe condition. These contacts may be used to operate
the ‘No Hazard, Laser Off’ section of a Lasermet dual message illuminated sign.
The controller also has a pair of contacts which close to indicate that all the interlock and emergency
stop inputs are closed. These may be used for example to signal to a PLC that all doors are closed,
and no emergency stop buttons are operated.
The ICS-6-OEM has a mismatch detector which, when wired to a full dual-channel system, disables
the system in the event of a mismatch between the two safety circuits. This provides protection
against the failure of a door switch etc.

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
MTTFd 381 years
Mission Time 20 years
Diagnostic Coverage (DC) 99% (HIGH)

5 Installation
The ICS-6-OEM 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.
Whilst the unit itself operates on 24VDC it is possible that higher voltages fed from other equipment
may be present on its output contacts.
5.1 Positioning
The ICS-6-OEM 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.
During installation, wired connections will need to be made from the ICS-6-OEM to all the
interlocked doors, warning signs, laser interlocks, shutters, PLC 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.

Figure 1. ICS-6-OEM Top Label showing terminal
identification
Nearest the edges of the label are indication lights which
show the position of the interlock and arm input signals and
the state of the controller.
Next to these, on a green background, are the identifications
for the top rows of terminals. The “Top terminals” refer to
the terminals at the front of the unit.
Nearest the centre of the label, on a pink background, are
the identifications of the bottom row terminals. The
“Bottom terminals” refer to the terminals at the rear of the
unit.

6 Wiring
The ICS-6-OEM 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.
Figure 2. Example overall wiring scheme
6.1 ICS-6-OEM Inputs
Mechanical Interlock Switches
Up to six door/cover interlock switches may be directly wired to the ICS-6-OEM. By making external
connections, more switches can be added and arranged in groups.
The interlock switches are wired to the terminals labelled INPUT 1 through to INPUT 6. 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-OEM.
A 4-way terminal block is provided for each door interlock switch. One of the safety contacts, which
are closed when the door is closed, is wired to the ‘A’ terminals. The other safety contact is wired to
the ‘B’ terminals.
The example diagram below shows a system with two doors wired for ISO 13849 performance level
‘e’. Each door has two switches.
