Can anyone assist with diagram of connections for anchor rod control system based on Hall effect?

Irek

It should count numer of revolutions (not rpm) of the gybsy wheel of the anchor winch./ik

Diagram that I have drawn can be sent to interested party./ik

    From a brief examination the setup looks reasonable, and there's decent confidence if you say you tested beforehand and it worked.

    Your actual deployment may be vastly different in unexpected ways, but it's not apparent from the notes. For example, the power source may be different, or cable lengths may be significantly different than the test setup.

    You need to do some basic voltmeter checks to confirm the correct voltages are present on the correct expected locations, maybe even do a continuity check with power disconnected, because connectors may have issues. Check if the sensor is inductive or magnetic sensitive, and is it being permanently stuck high or low due to other metal nearby. At slow revolutions you could probably test with an LED and resistor, temporarily detatching the sensor output wire from the counter, and wiring to the LED instead.

    Similarly, you could check the counter and wiring in isolation by temporarily disconnecting the sensor and applying a pulse manually.

    Best to buy a couple of sets of components so you can have a permanent testbed set up to compare against, since the parts are quite low cost.

    If it is hall effect, then perhaps also check the polarity of the magnet.
