How to Check if Reversing Devices Are Working Fine?

You can check if a reversing device such as through-beam sensor or photo-eye is working properly for your PULSE 500 Series door operator with one of the below two methods:

By checking the LCD for a UL325 Compliant or Non-Compliant message:

  • First power off the unit and then power it on again, and observe the LCD screen.
  • If the LCD screen displays the message: "UL325 Compliant", then the reversing devices are working as expected.
  • If the LCD screen displays the message: "UL325 Non-Compliant!", then the reversing devices are not detected.

Note: Make sure the reversing devices won’t shake while the door is closing. If they are, then attach the reversing devices directly to the wall instead of the door rails.

By checking the LED status on the control board:

  • If the reversing device is correctly aligned and connected to R1 and R3 on the control board, then the LED on the control board will be off.
  • If you have a monitored reversing device and is connected to R2 on the control board, then the LED will be on. If this does not happen, then you have to check the wiring and the alignment of the photo-eyes/reversing devices, as per the information in the installation manual .
  • In case you are using a monitored photo-eye on R2, and no reversing device on R1 and R3, then you need to put a jumper between P+ and R1, and also +24 and R3.

Note: If you use an external push button station, then check that the push button station uses a normally closed stop button. If not, check for a jumper between +24 and Stop on the control board.
