Re: SM Chain Counter Wiring
toggle quoted messageShow quoted text
Just brainstorming here...
What model display do you have? Is there a manual with a wiring diagram online?
What kind of sensor are you using (do you have a part number)? Is it magnetic? Optical? Our "aftermarket" sensor is magnetic. You can try passing a magnet in front of the sensor and seeing if the chain count increments.
How did you convert the normally open sensor to normally closed? What kind of relay did you use (hopefully normally closed?), etc...
Have you tried the new sensor with no inverting relay? The display might be edge triggered and may not care about polarity.
When we debugged our chain counter, we found that it requires: 1. A sensor on the windlass, and 2. An input (possibly from control panel) to indicate direction of chain travel.
Our sensor does not signal directionality at all.
Where does the blue wire go?

I am still trying to get my factory installed (SM #240) chain counter working. The old sensor by the windlass was indeed shorted out; I had to replace with a unit identical except for the fact that the old sensor was normally on, and the new sensor is normally off. I have managed to switch that configuration by inserting a relay in the circuit.
