8.1.12 Wiring Configuration for a Submersible Pump
The system consists of a submersible pump controlled by a Danfoss VLT
a 4–20 mA feedback signal to the drive, which keeps a constant pressure by controlling the speed of the pump. To design a drive for a
submersible pump application, there are a few important issues to consider. Select the drive according to motor current.

Notes/comments:
If the limit in the feedback monitor is exceeded, warning 90, Feedback Mon. is issued. The SLC
monitors warning 90, Feedback Mon. and if the warning becomes true, relay 1 is triggered. Exter-
nal equipment may require service.
However, if the feedback error goes below the limit again within 5 s and the warning disappears,
press [Reset] on the LCP.
