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.
