General:
Usage and Operating Principle of the Device:
It has been designed for controlling submersible pump motors and protecting them against adverse situations that can be arising from dry operation, high
or low voltage and high or low current.

Contacts:
Stop/Down Button:
Sets the device to the start position. It is used as the
down scroll button.
Start/Up Button:
Sets the device to the start position. It is used as the up scroll button in the menu.
Menu Button:
It provides to enter to the menu, to browse the menu, to save the value changes and to exit from the menu.
Reset Button:
It provides to reset the submersible pump manually after high or low current error and to exit from the menu.
Warnings:
When two electrodes are in use, the upper and lower electrodes are shorted
out and used together with the base electrode.
Connect the motor casing to the ground line. Otherwise, the device may
break down
Never energize the floater (Tank) terminals.
Make sure that the temperature is above 0°C in the place where the
device is mounted.
Make sure that the liquid is not flammable or explosive.
The device is connected in accordance with the connection diagram.
Be sure to read the warning section before connecting the device. Connect the device according to the connection diagram. After you have connected the
device, power it up. Set the switch to "1" to switch on the appliance. Compare whether the factory values on the device's menu match the operating values of
your motor. If not, respectively;
If you want to automatically reset after high voltage (P1), high current (thermal) (P2), low voltage (P3), low current (P4), current error waiting time (P5),
current error automatic reset time (P6) demurrage multiplier (P7), demurrage time (P8), the current auto reset number (P9),
and the top electrode standby time (P10)
After the device is energized, it will wait 4 seconds for the first power-on time. The system then examines whether there is water in the well, whether the tank
to be filled with water is empty or not, according to the voltage values set from the menu. If the water level is above or in the middle of the water level, if the
voltage value is within the normal values, the tank is empty and the device is in the start position, the motor starts to run and the engine is running. The engine
starts up and the inrush current appears for the first few seconds. The motor then falls to its normal operating current. Voltage in the red display group and
current values in the yellow display group appear on the display.
Start position:
When the unit is in the start position, start led is on. Press the start key to get to the start position.
Stop position:
When the unit is in the stop position, stop led is on. Press the stop key to stop. The device does not operate under any conditions while in
stop mode.
As the Well is being Drained:
When the water in the well comes into contact with the upper electrode, the well is full (Upper Elc.) And the engine starts.
When the water drops below the top electrode, the well is burned in the middle level (Lower Elc.). The engine starts. When the water drops below the bottom
electrode, the well is empty (Bottom Elc.) And the engine is stopped.
As the Well is being Filled:
If the water in the well is below the lower-eletrode, the well is empty (Bottom Elc) and the engine does not start. When the water
comes into contact with the bottom electrode, the well is on the middle level (Lower El.) And the engine does not start. When the water comes into contact with
the upper electrode, the device waits for the upper electrode waiting time while the well is full (Upper Elc) flashes. After the time has elapsed, the well (Upper Elc)
is constantly lit and the engine is started.
Tank:
Make the connection of the short-circuited when the tank is empty. Never apply energy to the appliance floater inlet. If you are not going to use the
device's tank feature, short-circuit the floater inlet
Tank is Empty:
When the floater inlet is short-circuit, the tank is detected as empty and tank full led is off.
Tank is Full:
When the floater inlet is open-circuit, the tank is detected as full and tank full led is on. Under no circumstances will the engine start when the
tank is full.
If the motor is not running:
If the "MOTOR ON" led is not lit, Check that the device is in the start position. Check that the tank is empty. Check the tank
LED is not lit. See that the "full" LED is on continuously. Iif flashing the "full" led the device is counting the top electrode waiting time. Also, the voltage values
may be outside the set values, or high or low current may have entered the fault.
Cut the energy of the device and disconnect its connections. Clean
the device casing with a slightly damp cloth. Do not use conducting or
other substances as cleaning agents that can harm to the device.
After the cleaning of the device is completed, make the connections of
it and be sure that it operates by energizing it.
