What Is a Passpoint and How to Reset It
The passpoint is found in the travel module that is connected to the motor. The travel module has been called an encoder or positioning sensor. Our DC motors have used a passpoint system as part of its electronic limit and force settings, beginning with model 2500. Security+ 2.0 Garage Door Openers use a travel module for both motor types, AC or DC.
The travel module is an example of a limit switch and RPM sensor in one. The travel module uses RPM count to determine motor speed and check for obstructions, and the passpoint to know where the location is in travel. When the travel module sees the passpoint it starts counting RPM to know when to stop in the open or closed position.
The passpoint is factory set. If the trolley is installed in the closed position the passpoint would occur at the center of the rail. Older models are shipped with the limits in the down position. If the unit was run before the installation was finished, an issue without of phase may result. On new units the passpoint may be in a bad spot, making it harder for the unit to keep track of its limits.
If the passpoint occurs close to the end of travel, for example, one foot from the open position, the unit may not see the passpoint consistently to keep track of the limits. If the door is opened partially and closed several cycles without seeing the passpoint, this could affect the operator's ability to know where it is exactly and cause the limits to come out of adjustment.
When the door is traveling, the LED in the door control will blink when the passpoint is reached. On an LCD door control, the screen will flash when the opener reaches a passpoint. The passpoint should be at mid-travel, plus or minus a foot. If needed, follow these steps to reset the passpoint.
- Start with the door in the closed position. Be ready to stop the door with the push button or unplug the operator.
- Note: If you will be unplugging the opener to stop it, be sure to have the battery wires disconnected as well if the opener has a backup battery installed
- Run the unit open. As soon as the LED or LCD screen flashes, stop the unit or unplug it.
- Loosen the belt or chain. Move the trolley to mid-rail. Re-tighten the belt or chain. This will set the passpoint at mid-travel.
- Reset the up and down limits, according to the manual.
Make sure you also test the Safety Reversal System after making any adjustments.
As of November 15, 2020, Security+ 2.0 Garage Door Openers are now manufactured with obstruction notifications in the event the garage door encounters an obstruction while operating.
For existing Security+ 2.0 Wi-Fi Garage Door Openers that are connected to Wi-Fi, the firmware has been updated automatically so it will now provide obstruction notifications. Note: The garage door opener must be connected to Wi-Fi in order for the update to occur.
If the opener is not a Wi-Fi enabled Garage Door Opener and is within the warranty time frame, the logic board can be replaced. Replacing the logic board will provide obstruction notifications once it is installed.
