Hörmann A 445 control unit for WA 400 industrial door operator

This control unit replaces a damaged central unit of the Hörmann A 445 control, which operates the WA 400 industrial door operator. When it fails, the door usually stops working completely. The main board and power board are pre-assembled on a plastic carrier, so you replace the unit by loosening a few screws.

Which controls it fits

The unit is designed for Hörmann A 445 controls manufactured from 1/10/2003. It has connections for external control devices, the control elements on the housing, the AWG absolute encoder, mains voltage and the motor.

What else to order

The unit is supplied without connector strips and without the bag of screws. Depending on your wiring, you may need:

• X 90 for 230 V (638155) or 400 V (638156),
• X 91 3-pole (638157) or 2-pole (638158),
• X 91 for the motor connection, screw-type (638159) or for WA 400 FU (638160).

Before replacement

In the event of a fault, first find out its cause. Check the parts you will continue to use for damage. For the WA 400 operator we also offer a slack cable switch and, for upgrading the A 445 control, a multifunction expansion board with two relays. A replacement display board for the A 445 control is supplied separately. You connect a safety edge or light curtain on the door leaf via the 8K2 connection unit. You can order the strips via eshop@saver.sk. More parts can be found in the garage door spare parts category; in the Košice and Prešov regions we carry out the replacement as part of our service.
