The ICS-6 Interlock System

ICS-6 interlock systems

The ICS-6 “ELISe” Expandable Laser Interlock System (to achieve performance level ‘e’) is designed to achieve EN ISO 13849-1 PLe. It is housed in a similar unit to the ICS-5, which is the most popular Laser Interlock Control System designed and manufactured by Lasermet, but the expandable ICS-6 has, as one of its options, remote monitoring.

This compact, versatile unit can control laser interlocks, door locks, illuminated warning signs and other equipment. It can operate beam shutters and the laser power with feedback monitoring and fault detection. It can be interfaced to Access Control and Fire Detection Systems and is fitted with an Override to allow controlled access through interlocked doors while also accepting emergency stop inputs.

The ICS-6 provides even higher levels of safety and functionality and has full start-to-end dual channel architecture and fault detection to meet the latest standards.

It has a simple, easy-to-use control panel which can be wired directly to 4 interlocks or groups of interlocks.

The ICS-6 functions include:

  • 3 Expansion card sockets
    The card types enable Integrated Active Laser Guarding (Laser Jailer), Safety Logic Plus integration, (for complex logic circuits and large numbers of interlock switches), and Ethernet/USB Connectivity which in turn enables ICS-6 interlocks to be monitored remotely – a real bonus to safety communications.
  • Full start-to-end dual channel architecture – for even higher reliability
  • Full start-to-end fault detection – simplifying analysis
  • Interlocked mains supply – for added safety
  • Interlocked low voltage supply for beam shutters – for faster integration
  • Laser interlock connector operators – for all lasers
  • Key-switch operation – to prevent unauthorized use
  • Arm laser button – just press to arm
  • Time limited fail-safe override option – for authorized personnel
  • Automatic switching of illuminated signs – indicating danger or safe modes
  • Emergency stop circuit – to prevent injury or damage in an emergency

ICS-6 can be configured as a locking or non-locking interlock system featuring:

  • Automatic fault detection and shutdown
  • LED indication for the Status of the following:
    • Interlock Switch
    • Expansion
    • Emergency Stop
    • Safety Circuits OK
    • System Overridden
    • Safety Circuit Fault (Mismatch Fault)
    • Laser Armed
  • Dual-redundant fail-safe circuitry
  • Dual Channel Override control
  • Feedback-based Sign Control – to maintain warning sign at Danger if the Shutter/power control fails to go to the safe condition when the system is disarmed

Example of interlock system layout

Further functions:

  • Can be used as a local laser controller as part of a larger system, which may be controlled by a master interlock controller
  • Optional safety status and ready status outputs can be provided to communicate with other Lasermet interlock controllers or a remote indicator panel
  • Surface-mounted, the ICS-6 has a “deep box option” for expansion cards or safety contactors to switch high power or multiple lasers
  • External facility to allow the system to be disabled by an external source e.g. supervisor’s key-switch
  • Operation of mains or low voltage signs
  • Integrated automatic switching of single or dual mode signs
  • Connect to virtually unlimited number of door contacts and Emergency Stop Buttons

Flexible Expandable System

Lasermet’s interlock controllers have earned a reputation as cost effective, reliable and highly flexible.

The standard ICS-6 can be expanded to have 9 interlock outputs by adding the IB9 interlock board. And by using the deep back box, contactors can also be added to give interlocked 32A single phase and 3 phase mains supplies. ICS-6 can be connected to other Lasermet interlock controllers to operate as a master or slave unit.

ICS-6 has an expansion socket and can be fitted with up to 3 expansion cards (which are automatically tested). There are 4 different types of card as follows that can be fitted:-

  • Integrated Active Laser Guarding option
  • Safety Logic Plus integration option
  • Ethernet/USB Connectivity
  • Uncommitted relay expansion card
