PUMP CONTROLLER 701
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 transmitter 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.

Installation and connection
Pressure transmitter
The pressure transmitter is immersed in
the well. The pressure transmitter can
be mounted in a tube, and fastened at
the top end of the tube, by means of
cable fittings.
If the pressure transmitter is
mounted in a tube, it facilitates
cleaning and inspection.
Internal diameter
min. 65 mm.

Pump Controller
Supply
230 V AC
Settings
Pump Controller 701 is operated from the front panel, where
start- and stop levels, or alarm setpoint for each relay output
is adjusted with 2 potentiometers. The pump controller is
adjusted by connection of a voltmeter between the test
bushes, marked "TEST" and "COMMON" and by adjusting
the potentiometer to the desired level. Dependent of the
"LEVEL" switch position, 0 - 3 / 0 - 30 m measuring range is
proportional with 0 - 3 V on the voltmeter and measuring
range
0 - 10 m is equal with 0 - 1 V.
The switch for alternation "ALTERNATION" is set on "ON", if
the pump controller shall be set for alternation.
The voltmeter - (negative) cable is connected to the test bush
"COMMON" and + (positive) is connected to the test bush
"TEST", opposite the function which has to be adjusted.
The pump controller is in operation when connected to
voltage, and calibration can always be made during operation.

PUMP CONTROLLER 701
Start- and stop setpoint
Start- and stop setpoint for the connected pump, is adjusted on
the two potentiometers. The circuit is implemented so the pump
is running when level reach the adjusted start setpoint, and
stops when level reach the adjusted stop setpoint.
Empty/ fill functions
The pump controller automatically changes between empty and
fill function. Dependent of start, set-point is adjusted to be
higher than stop set-point (pumping out), or stop set-point is
adjusted to be higher than start set-point (pumping in.)
Please note that the difference between start and stop set-point,
must be at least 2 % of the measuring range.
Alarm function
Pump Controller 701 can also be applied as level alarm if only
one pump is connected. Alarm set-point is adjusted on the
start- and stop potentiometer, opposite the chosen output.
Please note that the difference between start and stop set-point,
must be at least 2 % of the measuring range.

Maintenance
The pump controller requires no special maintenance, just as
the pressure transmitter normally not requires cleaning.
Cleaning of the diaphragm of the pressure transmitter, must be
exercised with great care.
