If there is a key on the display in the left bottom corner (the key is automatically activated after a period of inactivity), you need to unlock the access to the modification of the parameters by going to the home page and simultaneously pressing the button next to the display (the one away from the others) and the button underneath the key in the display, until the key on the display disappears. Now that the parameters are editable, just enter the values, paying attention because these can affect the inverter operation.

We recommend you read the instruction manual of the NKM-GE MCE-C, NKP-GE MCE-C (also available in our DNA software) for useful information for use, maintenance and installation. The manual of the MCE-C inverter (installed as a standard feature) contains further useful information.

To start the pump:

1.Fully open the gate valve on intake and keep the one on delivery almost closed.

2.Switch on the power and check that the motor is turning in the right direction, that is clockwise when viewed from the fan side. This check must also be performed after having fed the pump, activating the main switch with a fast start-stop sequence. If the motor is turning in the wrong direction, invert any two phase leads, after having disconnected the pump from the mains.

3.Once the hydraulic circuit has been filled with liquid, gradually open the delivery gate valve until its maximum allowed opening. The motor's energy consumption must be checked and compared with the value shown on the data plate, especially in cases where the pump has intentionally been given a reduced power motor (check the design characteristics).

4.With the pump running, check the supply voltage at the motor terminals, which must not differ from the rated value by +/- 5%.

The direction of rotation must be checked only in three-phase pumps (therefore pumps powered at 400 volts). In single-phase pumps (230 volts) the motor always rotates in the correct direction. The direction of rotation must be clockwise when viewed from the fan side. Otherwise invert two of the three phase leads, after having disconnected the pump from the mains. You may refer to its manual for all details. We recommend you read the instruction manual of the NKM-GE MCE-C, NKP-GE MCE-C (also available in our DNA software) for useful information for use, maintenance and installation.
