been wired correctly. You should be able to connect a multimeter to the 2 wires from the
switches and measure the resistance or continuity of the switches.
When the door(s) is open the resistance should measure open circuit or no continuity. When the
door(s) is closed the resistance should measure closed circuit, zero resistance or continuous
beeping.
There should be NO voltage present on the 2 wires. If these checks are OK then you can
proceed to connect the wires to the LightLas 532.
On the back panel of the Console Box is a connector marked INTERLOCK. Remove this
connector and then dismantle so as to gain access to the connector pins inside. You will notice
that 2 pins are linked together. These are Pins 2 and 3. Pin 2 is the common or ground
connection and Pin 3 is the Interlock input to the Microprocessor. When the LightLas 532 is
prepared at the factory this connector is always linked so the system can operate normally
without the Remote Interlock switches.
Remove the wire link and connect the Remote door switch interlock wires to pins 2 and 3.
Replace the connector cover and then plug into the back panel. Turn the Laser System ON and
confirm that with the Door(s) closed the Laser can function in Treat Mode but with the Door(s)
open the System locks up in Standby mode with an audible tone sounding continuously.
If the System functions OK then the connection procedure is completed.
