3 NMT MINI ER PUMPS
3.1

DESCRIPTION

NMT Mini ER xx/40,60,80 pumps are equipped with an additional module that allows control of the pump with the
voltage signal 0 to 10 V. The voltage signal can control pump pressure (depending if pump is set to proportional or
constant pressure) or speed (pump set to constant speed)
Pumps also feature a relay out, that is used a feedback signal for pump operation.

ANALOG INPUT

Control with a control signal is working, if the entrance resistance is <5 kΩ (cables connected). If the resistance at
the entrance is > 50 kΩ (cables not connected), the pump operates like an ordinary pump.
Pump response depending on the input voltage signal:
Input voltage signal
>9,5 V
>3 V - <9,5 V
>1,7 -<3 V
>1,2 V– <1,7 V
≤1,2V
