Well bore level gauge / Regulator for single phase pump DIN 30A

Control unit for single-phase submersible pump up to 4 kW, 150 V-270 V AC, 30 A, Tense

Art.No.: MDK-03

Electrodes (liquid level sensors) not included

Tense's new MDK-03 control unit is designed to protect single-phase submersible pumps from all potential problems that can occur during operation, including overvoltage and surges, lack of water in the well or borehole, and pump overload. Built-in features also allow you to monitor reservoir fill levels, set time delays for emergency situations, monitor surge currents and remotely turn the system on and off.

Protection Class: IP20

Operating temperature range: -20 °C to +55 °C

Cable cross-section: Max. 10 mm², electrodes up to 2.5 mm²

Weight: 0.25 kg

Installation altitude: Less than 2000 m

Controller operation

Please read the "Important!" section before connecting the device. Connect the sensors and the pump phase wire to the device according to the wiring diagram given in the data sheet and then connect the power supply. Check that the factory settings of the device correspond to the operating parameters of your pump. If necessary, the following parameters can be changed:

(P1) - Maximum permissible voltage (230...270 V, factory setting 245 V)

(P2) - Maximum permissible current (1...20 A, factory setting 5 A)

(P3) - Minimum permissible voltage (150...210 V, factory setting 160 V)

(P4) - Minimum allowable current (1...20 A, factory setting 0 A)

(P5) - Fault response delay (0...850 s, factory setting 2 s)

(P6) - Auto reset time after current error (OFF...850 s, factory setting OFF)

(P7) - Current multiplier for start-up interval (1...10, factory setting 3) (P8) - Start-up interval time (0...850 s, factory setting 10 s)

(P9) - Number of automatic resets of the current error after which the device enters emergency mode and requires operator intervention (VYP....200, factory setting VYP)

(P10) - Upper sensor response delay time (longer delay means the pump will turn on less times, extending its life) (0....850 min, factory setting 0 s min)

(P11) - Indicates if the electrodes are submerged in water: if the value is less than 230, there is water (red display indicates upper electrode, yellow display indicates lower electrode)

(P12) - Programs the memory of the last state of the controller before shutdown (0...1, factory setting 1)

After the initial connection to power, the device waits 4 seconds, then analyzes the network parameters and their compliance with the set parameters, checks if there is water in the well, if there is space in the storage tank, and if the controller is in "START" mode (green "START" indicator is lit), it turns on the control contacts and lights the upper green "pump" indicator. The displays will show the current voltage and current values.

To enter this mode, press the START button.

To enter this mode, press the STOP button. In this mode, the device does not perform any regulation and does not start the pump.

Please also note that if you plan to use the level relay without the float sensor and remote switch, make sure to place jumpers at the "ON-OFF" and "FLATOR" terminals; otherwise, the controller will not operate or will not operate properly.

Important!!! Please read this section before connecting the device:

- The submersible pump controller must be connected according to the wiring diagram in the product datasheet.

- Make sure that the liquid to be pumped by the pump is not flammable or explosive.

- The temperature at the installation point of the controller must be above 0 °C.

- Never apply voltage to the inputs of the controller to connect the float sensor.
