Heaters 15-11
Checking Zone Sensor
If the heaters are functioning normally, but do not turn on when a part enters that zone, it is possible that
the sensor is either burned out or not turned on.
To check a zone sensor:
1. In the Main window, click on
Tools.
2. In the Tools window, click on
I/O Test.
3. Click on
Conveyor.
> This opens the Test window, a list off all inputs and outputs.
4. Set the Interlock to ON (I).
5. Pause the dispensing system either by clicking on
Pause in the Run window, or by pressing the
Pause button on the dispenser control panel.
> Wait for all dispenser and conveyor motion to stop before opening the doors.
6. Open the doors.
WARNING! Even if the heaters appear to be OFF, they are still active and supplied with
power. Use extreme caution when troubleshooting the system heaters.
7. Manually move a part into the pre-dispense zone until it is directly under the zone sensor.
> For left-to-right conveyors, watch the Left Sense I/O in the Test window. For right-to-left
conveyors, watch the
Right Sense I/O.
8. If the Left or Right Sense I/O onscreen indicator does not turn ON, the sensor is not functioning.
