The QKS 14 uses a 12-pin and a 16-pin connector to the car controller. The manual maps:

A common mistake is swapping the encoder channels (A and B), causing the door to run away or reverse direction erratically. The manual includes an oscilloscope timing diagram to verify correct phasing.

The QKS 14 must "learn" the door stroke (open and close limits) after installation, power loss, or component replacement.

Standard Learning Procedure:

  • Once the cycle is complete, the LED should turn solid, indicating the parameters have been stored.

    • (Controller menu-driven; parameters and units vary by firmware version.)

    Always document final parameter settings and store in site file.

    Manual solution: The manual’s wiring diagram reveals that the reopening signal (terminal 7) may be pulled low by a faulty safety edge. Isolate the signal and test using the manual’s diagnostic jumper (JP4) to disable external inputs.
