3.1. DR 1000 electronic card
The functioning of the pump is managed by the
DR1000 electronic card that incorporates the
following functions:
- automatic functioning test of the pump every 48
hours of inactivity (with pump in the automatic
functioning mode).
- Pump control with signals coming from:
-
2 float switches:
one for starting-up and
stopping pump, one for the alarm maximum
level (optional).
-
3 float switches:
one for starting-up pump,
one for stopping the pump and one for the
alarm maximum level (optional).
