…the fuse blows each time a delivery is started?
The current consumption of the pump is too high for the HDA eco (max. 10 A).
An additional relay or safety device should be used.
The pump has a defect (e.g.: a blocked rotor). It should be checked.
…without intervention on the part of the user, the delivery is suddenly terminated?
The value of the delivery limit is too low. It should be adjusted (chapter
5.3.4.1.6)
The value of the maximum delivery time is too low. It should be adjusted
(chapter 5.3.4.1.7)
The delivery timeout value is too low. It should be adjusted (chapter 5.3.4.1.8)

spond with each other.
The interface connection is not correct. The connection should be checked
(chapter 3.1.5.3, chapter 3.).
The setting of the DIP switch on the RS422 converter set is not correct. The
