THREE PHASE METER EDMK

The EDMk three-phase electronic energy meter is capable
of me as ur in g co ns um ed a nd g en er at ed ene rg y (fou r
quadran ts) : Active energy (consumed an d generated),
inductive reactive energy (consumed and generated) and
capacitive reactive energy (consumed and generated), plus
metering partial energies.

Measurements are in true effective value, via three AC.
voltage and neutral inputs and three AC. current inputs. (via
…/5A, …/1A or .../250mA for MC3 current transformers).
The parameters measured and calculated are shown in
the variables table

This manual describes how to configurate and use the
ED Mk ene rgy meter. This man u al may b e f oun d i n
electronic format on the CIRCUTOR website:
www.circutor.com

Before any m ai nt en ance, modif ic at io n to
the connections, repair, etc., the equipment
must be disconnected from the supply. If any
operation or protection fault is suspected the

equipment must remain out of service ensuring against
any accidental reconnection. The equipment is designed
to changed quickly in the event of any breakdown

1. KEYBOARD FUNCTION.

The butto n allows the user to move through the
different energy groups (if any): tariff one and partial tariff,
or tariff one, two, three and partial tariff (EDM3k type). It
used in the set up menu it is used to enter the data and
move on to the next parameterisation screen.

The button allows the active or reactive energy display
options to be displayed. It is used in the set up menu
to increase the value by one digit if a variable has been
entered or selected.

Generated or consumed energy can be selected using

in the option. Inductive or capacitive energy can be
selected in the reactive option. In the set up menu is used
to move the cursor among the digits.

The button allows the display to come on in the
absence of any power supply. This function allows the on
site reading of meters when the device is out of service.
This option is available when the meter has an optional
station installed inside (see price list M3).

The button allows a quick access to the device’s full
parameterisation menu. To access this menu, press the
button for less than one second.

The button deletes partial energies. To do this, press
the button for less than 4 seconds. The message will then
display “donE”, indicating that these meters have been
successfully started (active and reactive).

Parameterisation in one step only).

2. STARTING UP

2.1. Previous information

2.2. Parameterization in one step only

Thi s option is only valid for installat io ns wh er e there
is no vol tage transfor mer to meas ure. Voltage is only
measured directly (300V AC f-N / 500V AC f-f) and current
measurement is via secondary external current transformers
of .../1A, .../5A or in model MC of .../250 mA.

Kee pi ng th e

butt on pres se d for 1 seco nd , the
energy meter enables the current primary and secondary
parameterisation on screen.
Usi ng and but to ns the v alue of th e current
transformer primary and secondary is validated using thel

button.

3. COMPLET MENU

Using the complet e parameteris ation of the mete r, all
setting options can be set. These options affect the setting
of the external voltage transformers, if any, as well as the
omission of energy meters which the customer believes to
of little relevance or are not required in their installation.

3.1. Voltage transformer

On screen the words “Pri U” appear followed by 6 digits.
Thes e allow the volta ge transformer primary to be set
(from 1 to 999.999).

On screen the words “SEC u” appear followed by 3 digits.
These allow the voltage transformer secondary to be set
(from 1 to 999).

3.2. Current transformer

On screen the words “Pri A” appear followed by 4 digits.
These allow the current transformer primary to be set (from

1 to 9.999).

On scree n the wo rds “SEc A” appea r followed by the
number 5 or 1. These allow the installed current transformer
secondary ratio to be set (5 =…/ 5A or 1 =…/ 1A).

* The option secondary in model MC does not exist (is
allways 250mA)

3.3. Measurement in 2 or 4 quadrants

On scre en the word s “QuA d” appear; on e of th e two
available options must be selected: 2 = power consumption
or 4 = consumption and generation.

3.4. Backlight disconnection time setting

On s cre en the words “diSP oF f” appear; the time the
backlight is on can be set after pressing the keypad. The
backlight is permanently on if 00 is set.

3.5. Display or not reactive energy

On screen the words “rEACt” appear; this option allows the
reactive energy to be displayed or omitted (“YeS” or “nO”).

3.6. Display partial energy counters

On screen the words “PArt” appear; this option allows the
partial active and reactive energy to be displayed or omitted
(“YeS” or “nO”). In the event of omission, the meter does
not show energy and stops metering energy.

3.7. Energy output pulse settings

The screen shows “Out ACt”; the energy to be associated
to digit al output 1 must be s elected: Consu med active
energy (import) or generated (export); once the data
has been entered with button, the W•h value must
be entered by pressing.The screen shows “Out rEA”: the
reactive energy to be associated to digital output 2 must be
selected: L / C- / L- / C; once the data has been entered
with the button , the var•h value must be entered by
pressing the keypad. In case of selecting 2 quadrants (see
section 3.3. Measurement in 2 or 4 quadrants), only are
available L or C.

The device has to be provided of an magnetic-thermal
switch to be disconnected. The fuses has to be type gl

6.4. Communications connections

De s cri p t ion of c o nne c t ion for the RS -48 5 bus , for
communication via an Intelligent Converter (485-RS232), or
via an Ethernet Converter (Transparent / Modbus/TCP).

6.5. Communications description

One or more EDMk meters can be connected to a computer or PLC. As well as the usual operation of each piece of
equipment, this system may centralize data at one single point. The EDMk has an RS-485 series communications
output. If more than one analyzer is connected to one RS-485 communication bus, it is necessary to assign to each a
peripheral address (from 01 to 255) so that the remote computer or PLC sends data on different measured or calculated
recordings to those addresses. The RS-485 connection is made with woven mesh shielded communications cables,
with a minimum of three wires and with a maximum distance between remote computer and the last analyzer of 1.200
metres. This RS-485 series bus can connect up to a maximum of 32 devices.The EDMk meter communicates using the
MODBUS RTU© protocol (Pulling Question / Answer).

7. DISPLAY / LEDS

- L1-, L2- and L3- shows that the device has measured voltage in each phase. If one of these does not exist, the corresponding identifi cation number does not
appear. The symbols appearing behind each phase (L) indicate the direction of the current in the current transformers, showing if the point of measurement
is consuming or generating energy ( L1, L2 and L3 fl ashing, informs of possible errors of connection of current transformers).

- T1, T2 y T3 (identifi cation only available on the EDM3k; shows the tariff selected for that time, independently from the tariff displayed on the upper
section.

- The

symbol indicates that load is inductive. The symbol indicates a capacitive load.

- The symbol shows that the meter is the fi rst and fourth quadrant (consumption). The symbol indicates that the meter is in the second and third
quadrant (generation).
