Linear PickLine – Reteach a Sensor

Before You Begin

Confirm the machine model and the component or screen being serviced. Record the original condition so the result can be compared after the procedure.

If a sensor malfunctions and is constantly sensing in the on or off position, you may need to simply “re-teach” the sensor. This is very easy to do and should take 5 minutes or less.

Open sensor diagnostics from the Sensors tab in the PickLine software. On a Retro C, open the PickLine tab and then select Sensors.

The lights on the right of the screen below are all off currently. They will turn green if they are active. This can help with diagnostics.

Step 1: Check that there is no debris between the sensor eyes and the reflector before teaching the machine. The sensors are located behind the cover shown below.

Step 2: Take the cover off of the sensor unit. Four 1/4-inch bolts hold it in place; only two are shown. Use a 7/16-inch socket or wrench to remove the cover.

Step 3: Press and hold the teach button on the sensor for three seconds without anything covering the sensor. It must see the reflector in order to teach the sensor properly.

Step 4: Load a board into the machine and confirm that each sensor works properly.

Step 5: Reinstall the cover with all four bolts using the 7/16-inch socket.

Confirm the Result

Recheck the completed work against the article, restore the machine through the approved startup procedure, and confirm the expected result in a controlled test before returning to production.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
