The Lasermet IS-MDC-12 is a dual channel magnetic door switch. If the mismatch detector is used in
the ICS-7-OEM, any single contact failure in the door switch will be detected and the laser inhibited.
In this switch the red and blue wires are taken to the ‘A’ terminals and the black and white wires to
the ‘B’ terminals. The green and yellow wires are not used.
For the highest level of safety two separate door switches may be used, one wired to the ‘A’
terminals and one to the ‘B’ terminals.
Emergency Stop and Break Glass Switches
The ICS-7-OEM treats Emergency Stop switches in the same way as Door Interlock switches. Ideally
the Emergency Stop switch should have two contacts which open when the button is pressed (2NC).
Connect one safety contact, which opens when the button is pressed, to the ‘A’ terminals of the E
STOP terminal block. Connect the other safety contact to the ‘B’ terminals.
If there are two or more switches, connect the contacts in series as shown below.
The Emergency Stop input may be driven by volt-free isolated contacts from a PLC or safety relay if
desired. The contacts must both be closed for the system to operate and they should be arranged to
operate simultaneously to avoid being detected as mismatched by the ICS-7-OEM.
If an emergency stop is not used, a wire link must be fitted between the two ‘A’ terminals on the E
STOP terminal block, and a second wire link across the ‘B’ terminals.
NOTE: The E-stop switch should be checked periodically.
ICS-LJM and ICS-LJM-SO
When the ICS-LJM or ICS-LJM-SO is used with the ICS-7-OEM, the output from the LJM must go into
the Emergency Stop input on the ICS-7-OEM.
