Highlights

 

Operation and software

The unique feature of GRINDE compared to all the other Elentek electrical panels is the function for reversing the run direction of the pump impeller.
This function reverses the gear at each start for a time that can be set from 1 to 10 seconds, in order to avoid blocking the rotor.
5 languages are available in the software to choose from (Italian, English, French, Spanish, German).

Electronic board

GRINDE control panels have a handy LCD display for reading the operating and alarm status as well as LED lights and programming and command keys on the front of the panel.
The main screen shows in any time the active motors, the input voltage and the current  absorption of the connected loads.
If operations with analog signals are used, the main screen also shows the percentage, meters or bars of the input signal.

Backward rotation function

GRINDE is characterized by the simplicity of programming and activation.
When switching the panel on, it starts in Automatic mode or according to the previous operating mode set before turning off.
The pump initially starts in backward rotation for a time set in the set-up menu, which can be from 1 to 10 seconds. Once the backward running time has elapsed, the pump will pause for about 6 seconds and then it will start running forward.
If the pump rotor is blocked the Automatic function can be deactivated and reactivated manually to start the pump in backward rotation.

Alarms

The GRINDE electronic board has a cumulative alarm output with volt free contacts 5A - 250V.
The messages of all alarm status are displayed on the LCD:
motor in protection, motor overtemperature, voltage too low or too high, sequence or lack of phases, maximum level, minimum level, pump service.

Pump service program

In the GRINDE programming menu there is the "Pump maintenance alarm" parameter, where to set a periodic alarm to carry on maintenance of the pump.
The display shows the total operating hours of the control panel with pump running (it cannot be reset) and the MAN.H value that can be set with the number of hours of pump operation after which I want the maintenance alarm to occur.
