The
Energy-230 D22
static energy meter is an appliance to read active energy in single-phase
230V systems. It is designed to operate in environments with overvoltage category III and
pollution level 2 according to EN 61010-1 standard.
SAFETY WARNINGS
To guarantee correct installation, proceed as follows:
1) The appliance should be installed by a qualified operator
2) The appliance should be installed in a panel in such a way as to guarantee that the terminals are
inaccessible after fitting
3) A protection device against over-currents should be installed in the electrical system, upstream
of the energy meter
4) Connect the instrument as shown in the alongside diagrams
5) Before touching the connector terminals make sure that the wires to be connected or already
connected to the instrument are not live
6) Do not power or connect the instrument if any part of it is damaged

• Housing: 2 DIN
• Protection degree: IP20/IP51 on the front
• Optoinsulated pulse output (only PULSE model) for energy consumption remote-monitoring
(0.1 kWh/pulse)
• Pulse specifications: duration = 100 ms ± 15%
voltage = 9 ÷ 24 V CC (± 10%)
switchable output current = 20 mA max
• Operating temperature: -10 ÷ +45 °C
• Storage temperature: -20 ÷ +60 °C
• Relative humidity: 10% ÷ 90% non-condensing
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 partial
counter is automatically updated as soon as the full scale is reached.
• 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 full 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
• Pressing again the key “Sel” you move to the display of the
instantaneous
power
. The resolution is fixed at 0.01 kW.
For values higher than 6kW
“---”
is showed.
• To return to the main page reading both meters (total and partial), press the
“Sel” key again
BACKLIGHTING
• 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/OFF backlight status will be displayed
for a couple of seconds, after which the main page will return.
PHASE ERROR
• When the energy meter is turned on, a connection check-up is
automatically carried out to detect any connection errors: in case of
improper connection the red led remains lit and the meter is locked. The
message “
phase error
” is displayed.
Warning: to restore correct meter operation after an error reading has been displayed,
switch the meter off, invert connections of voltage or current and turn on again.
