Points of attention

Check the points below

  • Check that the energy meter is correctly connected to the CT (current transformer) before setting up the energy meter.

  • The white wire / S1 of the transformer must be connected to the + terminal of the energy meter

  • The black wire / S2 of the transformer must be connected to the – terminal of the energy meter.

  • If connected incorrectly, there is the possibility that the current will be measured incorrectly. For example: connect black wire to the positive terminal of the energy meter.

  • See also the following article: Manual Eastron energy meters.

Settings

Press for 3 seconds until the password screen is visible.

The default password is 1000.
Enter the password using the up and down button:

If the password is different, you can navigate to the other numbers by pressing the E button once. You can then adjust them with the M and P buttons.

Press for 3 seconds to confirm the password.

Changes in the settings are saved by pressing and holding the E button for 3 seconds.

If the password is correct, you will be sent to the Slave id menu.

Change slave id

The range runs from 001 to 247

In the setting menu, press the and keysto select the address ID 

Press the button to start the selection procedure. The current setting flashes.

Use the and keys to select the Modbus address (001 to 247).  

When the input procedure is complete, press to confirm the setting and press to return to the main setting menu.  

If you see the message GOOD, the setting is set successfully.

CT clamp setting

The CT options set the secondary current (CT2, 5A, or 1A) of the current transformer (CT) used with the meter.

Use thebuttons to select the menu option.

Secondary CT setting: Press and hold the button to set the secondary CT option: 5A (default) or 1A.

Set the value of the CT ratio: Press and hold the button to enter the CT ratio setting screen. The range is 0001 to 9999.

CT ratio

The CT ratio is the primary CT divided by the secondary CT.

For example, for 200/5A current transformers of which CT1 = 200 and CT2 = 5:

200 ÷ 5 = 40, so the CT Ratio would then be 0040.

Or with a CT100/1A, the ratio is 100 / 1 = 100

On the MID version, you can only program the CT-Ratio once.

This energy meter can be set to function with CT terminals from 1A to 5A secondary current. When choosing current transformers, the primary current of the transformers should be equal to or greater than the load current of the circuit you want to measure.

To avoid errors in the energy measurement, the P1 port of the CT must be pointed towards the power supply. However, if the P2 port is facing the power supply, you can still correct it with the Handleiding Eastron energiemeters  help of the current direction chapter.
