General product description, features and optional functions

2.1 Product description
The MultiControl Duo pump control system is used to control the levels of fluids.
The fill level is determined by means of the ram pressure, air bubbles, an external sensor (4 - 20 mA) or float
switch, as required. The motor contactors actuate two pumps with a maximum power of 4 kW (optional to 5.5
kW) directly. 5 relay contacts are also available for issuing fault messages.
Operation and adjustment are extremely easy. Switch points, times and motor current limitation are set with a
digital potentiometer. All values can be retrieved on the LCD display.
LEDs indicate operating statuses and fault messages. Buttons for the manual - 0 - automatic functions are
also available.
