Why Is My Photo-Eye Not Reversing the Door?

If the photo-eye is not reversing the door for your PULSE 500 Series door operator, then follow the next steps:

If you are using an unmonitored photo-eye:

  • First, ensure that it toggles when blocked and unblocked.
  • Next, verify that the wiring is correct and that the reversing input (R1, R2, or R3) is getting +24V when the photo-eye is aligned.
  • If the photo-eye behaves normally when the door is stationary but does not trigger the door to reverse when moving, it could be getting jammed by the frequency of the motor when it is running.
  • Try changing the PWM frequency in the ADVANCED MENU.

If you are using a monitored photo-eye:

  • Check the value of the resistor powering the photo-eye between R2 and +24 terminals.
  • For the Vitector OPTOEYE photo-eyes provided with some PULSE door operators, a 1K ohm resistor is required.
