| Symptom / Error Code | Possible Cause | What to Do | | :--- | :--- | :--- | | on display; system only responds to "Open" button | Power failure or drive disengagement has occurred; the door needs to find its reference position. | Run the door to the fully open position. This action will clear the code. | | E04 on display; after a few operations, the door only goes up; must use hold‑to‑run to go down | A problem with the safety edge monitoring system; possibly a faulty connection or a missing jumper (e.g., on connector X3) for the photocell module. | Perform a full system reset by disconnecting power for 5 seconds. Check all connections on the photocell module and the manoeuvring card. Re‑install the operator according to the installation instructions. | | Door does not start at all | Drive unit is disengaged; power supply is off; emergency stop button is pressed. | Pull the red ball cord to re‑engage the drive. Check the circuit breakers. Verify the emergency stop button is released. | | Door moves, but stops and reverses on its own | Obstruction on the tracks; door is not properly balanced, triggering the torque guard. | Clear the tracks of any debris. Perform the door balancing test (see Section 10). If the door is unbalanced, contact Crawford for service. | | Door does not close fully; it stops before reaching the floor | Obstruction in the final 5cm of travel; the safety edge has been triggered. | Clear any obstacle. Check the condition of the pneumatic hose and the pressure switch. | | Yellow LED on control box is lit | The programmable service interval has been reached. | Perform the required maintenance as outlined in the service manual. Then use the d07 or d08 menu to reset the service counter. | | The motor does not stop at the open/closed positions | The limit switches may not be programmed or are faulty; the encoder may be damaged. | This may require a full position programming cycle. Check the limit switches and their wiring. If the encoder is broken, the door will only operate in hold‑to‑run up. |
