- For an NPN type transistor, set the switch labeled '1' to ON and the switch labeled '2' to OFF.
- If instead, you are using a PNP type transistor, then set the switch labeled '1' to OFF and the switch labeled '2' to ON.

Ensure these sensors are aligned and their wiring is correct, as per the installation manual .
Here's how to check if the reversing devices are working as expected.
Here's how to check if the reversing devices are working as expected.
- Ensure the sensors are aligned and wired correctly as per the installation manual.
- Turn the unit off and on again and observe the LCD screen.
- An "UL325 Compliant" message indicates the device is functioning correctly.
- An "UL325 Non-Compliant" message means the device isn't detected.
- Ensure the device is stable and doesn't shake when the door closes; if it does, secure it to the wall rather than the door rails for better stability.
- Ensure the sensors are aligned and wired correctly as per the installation manual.
- Turn the unit off and on again and observe the LCD screen.
- An "UL325 Compliant" message indicates the device is functioning correctly.
- An "UL325 Non-Compliant" message means the device isn't detected.
- Ensure the device is stable and doesn't shake when the door closes; if it does, secure it to the wall rather than the door rails for better stability.
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.
Follow these steps to wire in the photo-eye:
- Wire the solid black cables from the receiver and transmitter to the COM terminal on the control board;
- Wire the dotted black and white cables from the receiver and transmitter to the R2 terminal on the control board;
- Remove factory supplied resistor between R3 and +24, and wire that into R2 and +24;
- Connect normal jumper cables between R1 and P+, and R3 and +24 to bypass those inputs;
- Alternatively you can hook up a second photo-eye into R1, then a third photo-eye into R2 terminal.
R1 terminal:
- The R1 input is the primary input for reversing devices when there are no monitored devices in the system.
- The R1 input is special because it is used in tandem with the P+ terminal.
- P+ is a +24V output toggled off and on during operator boot-up and on close to check for a delay with R1.
- This delay indicates that there is a device connected to the R1 terminal instead of a jumper.
- This is done to stay compliant with UL 325 standards which require at least one photo-eye to be connected to the system for the door to close automatically.
R2 terminal:
- The R2 input is for monitored devices and takes priority over R1 when connected.
- This input is always communicating with the photo-eye itself and is the safest.
R3 terminal:
- The R3 input is a simple relay-based input that requires +24V to stay active.
- This input can only be used as a secondary or tertiary input when R1 and/or R2 are hooked up.
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.
