Cable tie wrap installation
•
If applicable, unscrew the two bracket screws, rotate the bracket 90 degrees, and tighten the bracket into position with
the two screws.
•
In close proximity to the sign, route the cable tie wrap through the slots in the light sensor bracket and around the pole.
Make sure it is facing the same direction as the front of the sign before tightening.
2. Connect the light sensor to the sign
Adaptive Micro Systems recommends that you turn off power to the sign prior to connecting the light sensor. The sign will
only recognize the presence of the light sensor when it first starts. So, if you connect the light sensor while the sign is
powered up, you will have to cycle power to the sign in order for it to acknowledge the presence of the light sensor.
3. Route the light sensor cable to the customer interface panel on the back of the sign’s controller case.
4. Plug the light sensor cable into the port on the back of the sign. Leave a sufficient amount of slack to create a “Service
Loop”.
Note: The sign will not acknowledge the presence of the light sensor(s) until power is cycled.
