    Why does the D+H RZN 43-E smoke vent open without an external alarm?
    • S
      Shane JohnsonAug 14, 2025
      If the D+H Control Panel smoke vent opens without an external alarm and can be reset again, it's possible that an external system is sending short, unintended signals due to a malfunction, a previous alarm, or a false alarm that was reset without your knowledge. If this happens repeatedly, disconnect the contact and investigate the external system for faults.

    Why is the LED diode lit on my D+H RZN 43-E Control Panel?
    • L
      Lisa FinleyAug 18, 2025
      If the LED diode on your D+H Control Panel is lit, there could be several reasons: * **Earth Fault:** You should eliminate the earth fault. * **Accumulator Malfunction:** Check the accumulator, its connection, and the fuse. * **Power Supply Issue:** There might be no 230V power supply available. In this case, immediately call an in-house electrician to resolve the power failure.

    What to do if pilot light OK extinguishes during closing operation of drive, red LED diode lightens, flap can't be closed in D+H Control Panel?

      Lisa RodriguezAug 21, 2025
      If the pilot light labeled 'OK' on your D+H Control Panel extinguishes while the drive is closing, the red LED diode lights up, and the flap cannot be closed, it indicates a group malfunction. You should check the terminal resistor or terminal module between terminals 5 and 7.

    Why does pilot light OK extinguishes during opening operation of drive after approx. 20 seconds, red LED diode lightens in D+H RZN 43-E?
    • G
      Gerald GeorgeAug 25, 2025
      If the pilot light labeled 'OK' on your D+H Control Panel goes out during the opening operation of the drive after about 20 seconds, and the red LED diode lights up, it suggests a malfunction in the group. To resolve this, check the terminal resistor or terminal module between terminals 5 and 6.
