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.
