Level gauge for tank well bore / Regulator for single-phase pump DIN 30A

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

Code: MDK-03

Electrodes (liquid level sensors) are not included

New the MDK-03 control unit from Tense is designed to protect single-phase submersible pumps against all possible issues that may arise during operation, including overvoltage and current surges, lack of water in the well or well and pump overload. Built-in functions also allow monitoring the level of the tank, set time delays for emergencies, monitor surge currents and remotely turn the system on and off.

Operation regulator

Before please read the section "Important!" when connecting the device. Connect the sensors and phase conductor of the pump to the device according to the wiring diagram provided in the data sheet and then connect the power supply. Check if the factory setting of the device corresponds to the operating parameters of your pump. If necessary, it can be changed the following parameters:

(P1) – Maximum allowable voltage (230…270 V, factory setting 245 V)

(P2) – Maximum allowable current (1…20 A, factory setting 5 A)

(P3) – Minimum allowable voltage (150…210 V, factory setting 160 V)

(P4) – Minimum allowable current (1…20 A, factory setting 0 A)

(P5) – Response delay to error (0…850 s, factory setting 2 s)

(P6) – Duration of automatic reset after power failure (OFF…850 s, factory setting OFF)

(P7) – Current multiplier for the start interval (1…10, factory setting 3) (P8) – Duration of the start interval (0…850 s, factory setting 10 s)

(P9) – Number of automatic resets of the current error, after which the device goes to emergency mode and requires operator intervention (OFF....200, factory setting OFF)

(P10) – Response delay time of the upper sensor (longer delay means that the pump turns on less often, which extends its lifespan) (0....850 min, factory setting 0 with min)

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

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

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

Mode "START": To enter this mode, press the START button.

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

Please note also, if you plan to use a level relay without a float sensor and of the remote switch, ensure that you are on the terminals 'ON-OFF' and 'FLATOR' you have placed the jumpers; otherwise, the regulator will not function or will function incorrectly.

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

- The submersible pump regulator must be connected according to the wiring diagram as stated in the product data sheet.

- Ensure that the liquid to be pumped is not flammable or explosive.

- The temperature at the installation site of the regulator must be above 0 °C.

- Never do not connect voltage to the inputs of the regulator for connecting the float sensor.
