Interlock Control for X-ray machines

Lasermet's X-ray interlock controller is a high specification interlock control system that is ideal for use with X-RAY sets. It forms an essential part of the engineering controls required for restricting exposure to ionising radiation and conforms to the requirements of "Work with ionising radiation" Ionising Radiations Regulations 1999: Approved Code of Practice and guidance.

Lasermet are world leaders in dedicated interlock system design, manufacture and installation. Lasermet also design and manufacture a large number of accessories including door contacts, access keypads, fingerprint access units, illuminated LED warning signs, recorded audible warning systems (audible alerts) and more.

Lasermet provides full system, design, supply and installation so customers can be sure the specification, selection and conformance requirements to achieve a bespoke, certified, safety control system. Lasermet supports its customers through distributors and sales offices around the world.

Interlock Control

The ICS-6 is an expandable Radiation Interlock Control System, designed and manufactured by Lasermet, which can achieve EN ISO 13849-1 performance level 'e' (Safety of machinery - Safety-related parts of control systems), when used with the appropriate equipment and wiring.

This compact, versatile unit can control interlocks, door locks, illuminated warning signs and other equipment. It can operate interlock switches 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 the highest 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:

  • Expansion socket capable of taking up to three expansion cards. The expansion cards enable additional features such as:-
    • Safety Logic Plus integration, (for complex logic circuits and large numbers of interlock switches)
    • Ethernet/USB Connectivity which in turn enables ICS-6 interlocks to be monitored remotely - a real bonus to safety communications
    • Uncommitted additional relays
  • Full start-to-end dual channel architecture – for the highest safety reliability
  • Full start-to-end fault detection, cross checked – simplifying analysis
  • Volt-free Interlock Operators to enable X-Ray emission
  • Interlocked mains supply –
  • Interlocked low voltage supply 12/24VDC
  • Built-in automatic warning sign control for mains or 24VDC illuminated signs
  • Key-switch operation - to prevent unauthorised use
  • System arm button – just press to arm
  • Time limited, fail-safe, override option – to enable authorised personnel to enter or exit a room
  • Emergency stop input
  • Automatic door lock control
  • Control system not software-based- indefinite maintainable service life

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)
    • System Armed
  • Dual-redundant fail-safe circuitry
  • Single or Dual Channel Override control
  • Feedback-based Sign Control – to maintain warning sign at Danger if the power or interlock control fails to go to the safe condition when the system is disarmed

Further functions:

  • Can be used as a local 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
  • Three volt-free isolated output contacts as standard, expandable to nine
  • Surface-mounted, the ICS-6 has a “deep box option” for expansion cards or extra output contacts
  • External facility to allow the system to be disabled remotely 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. ICS-6 can be connected to other Lasermet interlock controllers to operate as a master or slave unit.

Standards

ISO 13849-1:2006 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. It applies to SRP/CS, regardless of the type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.), for all kinds of machinery. It does not specify the safety functions or performance levels that are to be used in a particular case.

ISO 13849-1:2006 provides specific requirements for SRP/CS using programmable electronic system(s).
