Electrical Connection - IMPPUMPS NMT Plus PWM H/S 40 Manuel D'installation Et De Fonctionnement

1
These instructions are intended as a supplement to NMT Plus ER xx/40,60,80,90 and NMT Plus PWM S or H
xx/40,60,80,90 pumps. This guide describes how to control pumps with an external signal.
2 NMT PWM
2.1 DESCRIPTION
NMT Plus PWM xx/40,60,80,90 pumps are equipped with an additional module, which enables control of the pump
with the PWM signal. Module on the pump has one of the two profiles of operation, which vary depends on the
system in
Pump response according to the input PWM signal
profile
10% or no signal
>10% - 84%
>84% - 91%
>91% - 95%
>95% - 100%
Input value of the PWM signal can be monitored through indicators that indicate 3 curves.
>66,6% - 100%
>33,3% - 66,5%
0% - 33,3%
Charts of curves are located at the end of the manual.

ELECTRICAL CONNECTION

Signal cable for PWM signal is led at hydraulic casing through a small gland in the electrical cabinet. Cable should be
–
>90% - 100%
>15%- 90%
