1. The sensor is mounted incorrectly (i.e. handed sensors are installed in the opposite manner). Observe the hinge arrow on the sensor label.
2. The sensors are mounted to the header instead of to the door.
3. The sensor detects panic hardware installed on the door. Use the provided spacer.
4. The mounting template was used incorrectly.
1. The door did not open at least 80 degrees. Adjust the door for proper operation and then launch a new Learn.
2. The home switch is not breaking soon enough. Adjust the door for proper operation and then launch a new Learn.
Harnesses may be loose/damaged. Verify all connection points. The door may have been impacted or struck by an object.
Knowing act is turned OFF. In the ADVANCED menu on the hub, change Knowing Act to ON.
Activation is not going through the hub. All activation should go through the hub first and then through Logic Modules. If activation cannot be initiated through the hub, BEA recommends setting the system to Advanced Safety.
The On/Off/Hold Open switch is preventing activation. Using the provided jumper, wire-nut the red and black wires together and plug it into the ON/OFF/HOLD port on the hub.
1. There is an issue with the home switch. Ensure that the home switch is making and breaking correctly as the door cycles.
2. The door speed is set too slow; therefore, the door is not reaching a fully closed position before the system Learn completes.
Either the LZR-MICROSCAN power source is incorrect (e.g. powered from an unrecommended door control or from an AC transformer) or the temperature is too low or too high. Use from the LZR-MICROSCAN power supply included within the universal kits.
There is interference with sensor detection. Check transfer loop and door hardware. If the transfer loop is too long, trim it to an appropriate length. If hardware spanning the width of the door is causing interference, install the provided spacer.
Either the detection width is not set correctly (i.e. the distance from the sensor LED to the leading edge of the door) or the Guiderail height is not set (in the BASIC menu).
