The LS-20 Shutter has its own distribution socket. The wiring connections inside the distribution box
are shown below:
Shutter with own Power Supply
If your shutters have their own power supply or are to be run from an existing supply, you can use
one of the controller outputs to operate them. If the shutter requires a single contact to operate it,
connect the A and B contacts of the controller output in series as shown in the wiring diagrams
above for LS shutters, so that the shutter closes if either one or both output contacts open.
The connections should be arranged so that the shutter closes when the Interlock Operator contact
opens. Any ICS-7-OEM output used for shutters must not also be used for laser interlock control.
The contact is limited to 4A resistive load. If your shutter is solenoid-based it may need a protection
diode fitted to prevent possible damage to the ICS-7-OEM.
Interlock Connectors
Any of the ICS-7-OEM output contacts may be used to operate a laser’s interlock control, provided
they haven’t been used for any other purpose. The contacts are closed when the ICS-7-OEM is
armed. If there is more than one laser each must use its own output connector on the ICS-7-OEM.
Interlock sockets of several lasers must not be connected together.
Where the controller is part of a fixed laser system it is usual to directly connect the two devices. For
lasers with a single interlock channel use the following connections:
