3.1 DESCRIPTION
NMT Plus ER xx/40,60,80,90 pumps are equipped with an additional module that allows control of the pump with
the voltage signal 0 to 10 V. Possible
Control with a control signal is working, if the entrance resistance is <10 k
the entrance is > 50 k
Input value of ER signal can be monitored by indicators, which indicate three curves.
Charts of curves are located at the end of the manual.
3.2 ELECTRICAL CONNECTION
Signal cable for analog signal is led at hydraulic casing through a small gland in the electrical cabinet. Cable should
