General
Thank you for choosing MJK Pump Controller 704. The
MJK Pump Controller 704 is a microprocessor controlled
pump controller, which is delivered with a hydrostatic
measuring system (704P) or ultrasonic measuring system
(704U). The pump controller can control up to 4 pumps,
valves etc. It is appropriate for plants, where the controller
manages the data transfer to a central computer. The
pump controller is operated with a combined menu and
functional keyboard, making the installation and operation
simple and clear.
Hydrostatic measuring system
MJK Pump Controller 704P is delivered with a pressure
transmitter, covering measuring ranges from 3 to 30 m
(10 to 100 ft). The pressure transmitters are developed for
measurement of waste water and liquids with suspended
solids. All transmitters are designed as 2-wire 4-20 mA
transmitters.
Measurement is based on the following principle. A
pressure transmitter is lowered to the bottom of the solids
On the front you find:
Light emitting diodes
There are 4 light emitting diodes (LED's)
for indication of operation and alarms. The
LED´s light up when an output is active green when used for control and red when
used as alarm. The diode flashes during
the delay period.

By pressing one of the
keys from 1-4
(commonly
denominated as #) a
reading of the built in
datalogger is obtained
for number and period
of time, the output
relays have been
active.
If flow calculation is
applied, a second press
will show the pump
capacity and the
pumped out volume.
Third press will show
the pumped out volume
for the entire pumping
station.
Display
2 x 24 characters text display for
indication of user menus and
measuring values. When the keys
have not been pressed for approx.
1 min, the display will change
automatically to show the level.
to measure the hydrostatic pressure. The pressure
transmitter transmits an electrical signal proportional to
the pressure, resting on the pressure transmitters membrane. The pressure transmitter is connected to the
amplifier, where the signal is used for level indication, for
limits for start-, stop signals and alarms, as well as for the
level proportional 0-20/4-20 mA output signal.
Pressure transmitters are supplied in 2 versions for
absolute and gauge pressure.
Ultrasonic measuring system
MJK Pump Controller 704U with ultrasonic measuring
system, is delivered with 30 kHz ultrasonic sensor with a
resolution of 1 cm (0,3 in). The ultrasonic sensor both
sends and receives signals. In the amplifier the signals
received from the sensor are converted to a signal
proportional to the level.
With the ultrasonic sensor, the system has built in
temperature compensation for accurate measurings at
varying temperatures.

controlling, the levels for starting and stopping the pump
can be read. If the relay is configured as an alarm, the
levels for setting and resetting can be read.
If the pump controller is configured for filling (see menu
6.1) the start level will be lower than the stop level, and
vice versa if the pump controller is configured for
emptying.
LEVEL 2 START 1.80
STOP 0.20
If the relay is configured as a level alarm, there is an
alternative choice of adjusting the set levels to be either
higher (high alarm) or the contrary (low alarm) to the reset

level in menu 6.6.3.
LEVEL 1 SET 1.90
RESET 1.70
When adjusting a level, press one of the arrow keys,
consequently the setting will flash. Set the wanted value
with the arrow keys and confirm with ENTER. Double
arrow alters the value quickly, single arrow alters the
value slowly.
The highest value acceptable is the equivalent of the max.
level which has been programmed in menu 5.7. The
lowest value acceptable is 1% of the measuring range of
the sensor (reading in menu 5.1). The lowest range
acceptable between start and stop is 1% of the max. level
programmed into menu 5.7.
NB: If level indication with elevation is applied, the values
must be keyed in according to the elevation.
F6 Forced start
F7 Forced stop
Forced controlling is carried out by pressing one of the
keys 1-4 as well as the corresponding key for either start
or stop.
If the level is between the start and stop levels the pumps
stay started or stopped when the keys are released.
Above or below the interval between the start and stop
levels, the pump is only started/stopped while the keys are
pressed. The same applies if the level is not in use (menu
6.7.2).
If a pump which is configured for alternating control is run
forced, it is run as directly controlled during the forced
running. As soon as the forced running is stopped the
pump returns to alternating operation.
