Wiring a Limit Sensor

Some systems use active limit sensors that produce a voltage output rather than a switch or relay closure.

These devices must be wired differently than switches.

If your sensor has an open collector output or a sinking output, wire it like this:

If the sensor output goes low at the limit, select the option “closed” (in the software). If the output is open,

or high voltage, choose “open”.

Other sensors have sourcing outputs. That means that current can ow out of the sensor output, but not into

it. In that case, wire the sensor this way:
