Frequently Asked Questions - Energy-400 D90 Vemer

How do I install the Energy-400 D90 energy meter?

Installation must be performed by a qualified operator. Mount the meter on a DIN rail in an electrical panel that leaves terminals inaccessible after installation. Ensure an overcurrent protection device is installed upstream. Connect conductors as shown in the wiring diagrams, making sure they are not live before touching terminals.

What does the yellow LED indicate?

The yellow LED lights up to indicate a wrong connection. If it stays on after power-up, check the installation for connection errors. A detailed error diagnosis can be performed by entering the test mode (hold 'Sel' key for 4 seconds on the total energy screen).

How can I reset the partial energy reading?

Press the 'Sel' key to navigate to the partial energy display. Hold the 'Sel' key for more than 4 seconds to manually zero the partial meter. It also resets automatically when it reaches the scale end (9999.9 kWh).

How do I enable or disable the backlight?

On the main page (showing both total and partial readings), hold the 'Sel' key for at least 4 seconds. The backlight status (ON/OFP) will be displayed for a few seconds, then the main page returns. Backlight is enabled by default and stays on for 30 seconds after the last key press.

What is the accuracy class of the Energy-400 D90?

The meter has precision class 1 according to EN 62053-21, with a maximum measurement error of ±1.5% under specified conditions.

How can I test for connection errors?

During the first 3 minutes after power-up, the meter automatically checks connections. To manually test, go to the total energy page and hold the 'Sel' key for more than 4 seconds until 'tESt' appears. Negative energy readings (E1, E2, E3) indicate errors on the respective phases.

What is the maximum current the meter can handle?

The maximum current for continuous use maintaining class 1 is 100 A. The basic current is 10 A, and the maximum overload current is 90 A (though 100 A is specified for class 1).

How do I connect the pulse output?

The pulse output is an opto-insulated, open-collector type. It provides a pulse duration of 100 ms ±15% with a voltage of 9-24 VDC ±10% and a maximum switching current of 30 mA. Connect it to a compatible pulse input device.

What are the dimensions of the Energy-400 D90?

The meter has a width of 7 DIN modules (126 mm). Typical height is 90 mm and depth approximately 70 mm, but exact dimensions may vary.

How should I clean the energy meter?

Clean the exterior with a dry, soft cloth. Do not use water, solvents, or abrasive cleaners. The meter has no user-serviceable parts; refer to a qualified technician for any internal issues.

DIRECT CONNECTION ENERGY METER

Read all instructions carefully

■ Static meter with direct insertion to measure the the consumption of active energy in three-phase systems with precision class 1 (EN 62053-21).

SAFETY INSTRUCTIONS

To guarantee correct installation, observe the following instructions:
1) The appliance must be installed by a qualified operator
2) The appliance must be installed in an electrical panel which, after installation, leaves terminals inaccessible.
3) A protection device against over-currents must be installed in the electrical system
upstream of the energy meter
4) Connect the instruments as shown in the diagrams opposite
5) Before making contact with terminals, ensure that conductors to be connected to the
appliance are not live

3) Green LED: when lit it indicates power is on
4) Red LED: every flash corresponds to an energy count of 10Wh
5) Yellow LED: when lit it indicates wrong connection
6) Optoinsulated pulse output
8) Perforations for direct connection of wires to be metered

OPERATION

• When the energy meter is turned on the main page is displayed, representing the total energy count on the 7-digit upper block and the partial energy count on the 5-digit lower block. The resolution of each meter is automatically updated as soon as the scale-end is reached. If the YELLOW LED stays on after the implement was powered, check the installation for connection errors (cfr. "Connection errors") section.

- To display the total energy reading only, press the "Sel" key: this meter cannot be set to zero

- To display the partial energy reading, press the “Sel” key again: this meter is zeroed automatically as soon as the end of the scale is reached (9999.9 kWh); it can also be set to zero manually anytime by holding the “Sel” key pressed for more than 4 seconds

- To return to the main page reading both meters (total and partial), press the “Sel” key again.

Total reading

Partial reading

- Backlighting is enabled by default: it is switched on each time a key is pressed and stays on for 30 seconds after the last key was pressed. In order to enable/disable backlight while on the main page, hold "Sel" key pressed for at least 4 seconds: ON/OFP backlight status will be displayed for a couple of seconds, after which the main page will return.

Backlight status

CONNECTION ERRORS

During the first 3 minutes after power-up, a connection check-up is automatically carried out to detect any connection errors: the implement will light up the YELLOW LED if the energy at one or more phases appears to be negative.

In this case, for further details on the actual error type go to the total energy page and hold the "Sel" key down for longer than 4 seconds, until the "tESt" reading appears.

Wrong connection is indicated by a negative energy reading (E1 and/or E2 and/or E3) followed by the "Error" message.

PHASE 1 error
E1 is negative

PHASE 2 error
E2 is negative

PHASE 3 error
E.3 is negative

PHASE 1 and 2 error
E1 and E2 are negative

PHASE 1 and 3 error
E1 and E3 are negative

PHASE 2 and 3 error
E2 and E3 are negative

TEST

PHASE 1, 2 and 3 error
E1, E2 and E3 are
negative

The test can be performed anytime by simply repeating the above steps.

Warning: to restore correct meter operation after an error reading has been displayed, switch the meter off, check connection of phases (sequence of phases R, S, T) and current; then power the meter up.
