Instruction manual
General
Thank you for choosing Pump
Controller 701. Pump Controller 701
is a new compact unit for level
control of 1 pump and 1 level alarm,
or 2 pumps in alternation.
Pump Controller 701 is supplied in a
housing for DIN rail mounting and is
easy to install and operate from the
front panel.
Hydrostatic measuring system
Pump Controller 701 is supplied with Pressure Transmitter 7060
or 7070 covering measuring ranges from 0 - 3 m to 0 - 30 m.
Pressure Transmitter 7060 is manufactured in polypropylene
and developed for measuring in wastewater and liquids with
suspended solids. Pressure Transmitter 7070 is manufactured in
stainless steel, with small external diameter and is applied in
clean liquids such as water drillings. The pressure transmitters
are manufactured as 2-wire 4 - 20 mA transmitters, which
generates an output signal proportional with the level.
Measurement is based on the following principle:
The pressure transmitter is immersed to the bottom of the liquid
and measures the hydrostatic pressure. The pressure transmit-
ter submits an electrical signal, which is proportional with the
pressure on the diaphragm of the pressure transmitter. The
pressure transmitter has an equalizing hose in the cable, for air
pressure compensation. The pressure transmitter is connected
to Pump Controller 701 where the signal is applied for start and
stop limits and alarm.
