4.5.2

Single Switch Wiring

If a single switch is used for controlling the traffic light, the user must select which two states (out of the four
possible), they wish to see.

4.5.3

Two Switch Wiring

If two switches are used for controlling the traffic light it is possible for the user to obtain any or all combinations
of the four possible states. Both switches with contacts closed will give the OFF condition, both switches with
contacts open will give the STOP condition, and one switch open and the other closed will give either the Go or
Arrow condition.

Connect the wires using the following procedures below.

An example procedure for connecting DIG 1 is shown below.

1. Disconnect the wire connecting D1 (pin 6 on J1) of the CPU to Dig 1 (pin 3 on J1) of the traffic light pcb at

the CPU connector.

2. Solder the wire going to Dig 1 on the traffic light board to the wire that will be going to the switch.

3. Place the wires back into the connector on the CPU board (pin 6 on J1).

4. Connect the other end of the switch wire to one pole of the switch.

5. Connect the remaining switch pole to the digital ground of the indicator (if a common ground between the

indicator and the Laserlight does not exist i.e.: fiber optic communication is used, then an additional wire
will be needed for connecting the switch to the ground on the Laserlight CPU).

This connection will not harm the CPU board since the digital outputs on the CPU board are designed to be
pulled low.
