KB132: SE8C - Yellow Signal Indication with Bi-Polar LED

This article was last updated on Jan. 10, 2012, 12:46 p.m. | Print Article | Leave Feedback

I would like to use a Tomar Searchlight Signal such as model # 858.

It has three color LED for each head.

The SE8C manual shows the wiring example for bi-color LED signals.

Is the SE8C able to control the three color LED signals as well?


The bi-pole LED's can be used to produce a yellow "Approach" indication.

The SE8C sends an AC signal to the LED, alternately lighting both the red and green sides to make a yellow (or "amber") Indication. Please see below:

"A2" is connected to produce an approach (yellow) indication.

You may find that the yellow color is not to your satisfaction.
