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
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.
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.
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.

Operation of pump controller
The keys under the display give access to the functions used in the daily operation. The MENU key gives access to programming of the pump controller. The programming can be locked separately with an access code i.e. a code must be keyed in, in order to get access to the programming menus.
Functional indications
When the pump controller is connected to 230 V, the display will show:
PROGRAM 8340XX
STARTUP WAIT A MOMENT
If the pump controller is activated for the first time, the display will show the following:
KEY IN NEW VALUES
PRESS ENTER
Now the pump controller can be configured. The settings can always be altered later on.
If the sensor type is changed, or if an output relay is either put into service or out of service, the programme will reset and new values must be keyed in.
F0 Level measuring
When the programming is carried out, function F0, level measuring in the display is shown:
MEASURING |
1.50 m |
If the pump controller is set up for level output according to a given elevation, both the level and the level relative to the elevation is shown in the display:
MEASURING |
1,50 m |
ELEVATION |
1,65 m |
F1 Starts / Operational time
By pressing one of the keys 1-4 number of starts are shown, as well as operation time for any of the relays 1-4 in use. If the relay is configured for operational relay the relay number is shown with a prepositive P for pumps. If the relays are configured as alarms an A will show:
P2 |
STARTS 4 |

If the MENU-key is pressed while the functional indication F0 is in the display, access is given to reset the counter and time counter:
P2 RESET COUNTER?
YES: ENTER NO:MENU
P2 RESET TIME-COUNTER?
YES: ENTER NO:MENU
F2 Capacity / Quantity
If key 1-4 is pressed while F1 is in the functional display, menu F2 will show:
P2 CAPACITY |
82 m3/h |
QUANTITY |
5508 m3 |
The capacity of each single pump is shown at this point, as well as the pumped out volume. When pressing the MENU-key while functional indication F2, access is given to reset the capacity and water quantities (if code is not applied, see menu 3.3):
P2 |
RESET CAPACITY |

Displayed here is the pumped out volume for the entire pumping station, as the sum of the pumped out volumes from all the individual pump’s. If the MENU key is pressed, the volume can be reset:
P2 RESET QUANTITY
YES: ENTER NO:MENU
F4 Level Start/Stop
F5 Level Set/Reset
By pressing START or STOP keys, the levels activating the relays can be read. If the relay is configured for 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

|
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.
Programming of pump controller
When function F0 shows in the display press the MENU key for access to the programming menus (if code is not applied, see menu 3.3). Change between the main menus by repeatedly pressing the MENU key. Press ENTER to change to sub menus. Make choices and adjustments in the sub menus with the arrow keys and confirm with ENTER.

3.3 Code only setup / all adjustments
The code can be chosen to only block the setup i.e. menues which are made accessible with the MENU key. Or it can be set to block all settings i.e. also start and stop settings for levels as well as reset of counters.
If a code has been chosen for all settings, alterations are made by entering menu 2.0 and keying in the code, now access is given to make alterations of all settings for 10 minutes after last key is pressed.
4.0 Measurement level / levels + elevation
Setting of level indication either as absolute measurement or relative measurement according to a given elevation. An altitude is the level reset-point which is valid on the relevant location, e.g. the elevation of the pumping station above the sea. I.e., if a pumping station is placed 1.25 m above the surface of the sea, and this is keyed in as an elevation, a level measurement of 2.25 m will be indicated as 3.50 m.
If level indication with elevation has been chosen, all start / stop values are programmed according to the elevation.
