1. APPLICATION
The PCE-ND10 meter is a digital programmable panel
meter destined for the measurement of the 3-phase, 4-wire
power network parameters in balanced and
unbalanced systems. It is also capable of displaying
measured quantities and their simultaneous digital
transmission. The meter is also capable of controlling and
optimization of the power electronic devices, systems, and
industrial installations. The meter can be used for measuring:
RMS value of voltage and current; active, reactive and
apparent power; active and reactive energy, power
parameters; frequency, 15-, 30- and 60-minute mean active
power and THD. Additionally, a current in the neutral wire
is calculated from the phase current vectors . Voltage and
cur-rent values are multiplied by given voltage and current
ratios of measuring transformers. Power and energy
indications take into account all programmed ratio values. Any
and all measured values can be sent to the master via the
RS-485 interface. The relay outputs signal alarm when
selected parameters exceed set limits. Impulse output can
be used for consump-tion check of the 3-phase real energy.
This meter is also able to detect and signal incorrect phase
sequence. The meter is powered by the measuring
circuit, i.e. from the voltage output.
There is a galvanic separation between following units of
the meter:
- voltage and current inputs,
- RS-485 output,
- pulse output.

3. BASIC REQUIREMENTS AND
OPERATIONAL SAFETY
In the safety service scope, the transducer meets to
requirements of the EN 61010-1 standard.
Observations Concerning the Operational Safety:
•The meter should be installed and connected only
byaqualiedpersonnel.Allrelevantsafetymeasuresshould
be observed during installation.
•Always check the connections before turning the meter on.
•Removal of the meter housing during the warranty period
voids the warranty.
•This meter conforms to all requirements of the electromag-
netic compatibility in the industrial environment.
•Building power network should include switch or automatic
circuit breaker positioned in the convenient vicinity of the
meter. It should be properly marked and available to opera-
tor at all times.

4. INSTALLATION
PCE-ND10 Meter is adapted to be mounted to the panel
with mounting brackets (see Fig. 1). Meter housing is made
of plastic.
Housing dimensions: 96 x 96 x 77 mm. On the outer side of the
meter there are screw and tab terminal strips that can be used
for connecting external wires with diameter up to 2.5 mm2.
Prior to installation a 92.5+0.6 x 92.5+0.6 mm slot must be made
in the panel. The thickness of the panel material should not
exceed 15 mm. The meter must be placed in the panel from
the front. During installation the powering voltage must be
off. When the panel is inserted in the slot, mount it in place
with provided mounting brackets.

5. METER DESCRIPTION
5.1. Current inputs
All current inputs are galvanically isolated (internal current trans-
formers). The meter is suited to operate together with external
measuring current transformers. Displayed values of currents as
well as their derivative values are automatically calculated using
set ratio value of the external transformer. Current inputs are
speciedintheorderaseither1Aor5A.
5.2 Voltage inputs
Displayed values of voltages as well as their derivative values
are automatically calculated using set ratio value of the external
transformer.Voltageinputsarespeciedintheorderaseither
3 x 57,7/100 V, 3 x 230/400 V or 3 x 290/500 V.

Caution: It is recommended to connect PCE-ND10 meters
(RS-485) to a computer with a shielded wire. A shield should be
connected to ground in a single point. Shielded wire must be
used in case there are many interferences in the environment.

6.3 Parameter display
In the measurement mode, values are displayed
according to set tables. Pressing button or
allows user to switch between displayed base values (Table 1).
Pressing button displays minimal value and pressing
button displays maximal value. When these values
are displayed, pressing the button resets all minimal
or maximal values. When buttons and are pres-
sed simultaneously, respective mean 3-phase values are dis-
played, together with minimal and maximal values (see Table 2).
RS-485 interface allows setting the values that are to be
displayed.
Error display is described in section 8.
When reactive power is displayed, this indication is accompa-
nied by a symbol of the load: capacity load ( ) or inductive
load ( ).
Basevaluesdisplayedintheeld17(Fig.4.).Option(parameter)
shown in the Table 1 indicated that displaying of this parame-
ter may be turned off in register 4056 via RS485. Turning this
parameter off (from U to tg) disables displaying their respective
mean / 3-phase values.

When upper limit of the indication range is exceeded, it is in-
dicated by two horizontal lines in upper part of the display.
Conversely, when lower limit is exceeded, it is indicated by two
horizontal lines in the lower part of the display. When mean
powerismeasuredΣP3-phase separate measurements are made
for 15-second quantum. Depending on chosen value (15 min, 30
min, 60 min) calculated mean value is based on 60, 120 or 240
measurements. After the meter is turned on or after the power is
reset,therstvaluewillbecalculatedin15secondsafterturning
meter on or resetting. Until all probed values of the active power
are acquired, mean power value is calculated from values already
measured. Current in the neutral wire I(N) is calculated from
phase current vectors.
When alarms are activated, symbols A1 and/or A2 are displayed.
When alarms are deactivated and alarm signalization latch is
turnedon,ashingsymbolsA1and/orA2aredisplayed.

The automatic erasing of energy is carried out:
- for active energy when changing: voltage or current ratio;
- for reactive energy when changing: voltage or current ratio,
reactive energy calculation method;
Buttons and are used for setting the values while
buttons and are used for choosing position
of the number to be set. The active position is signaled by the
cursor. Set value can be accepted by pressing the button
or canceled by pressing the button. When value is to
be accepted, it is checked against the acceptable value range.
If the set value falls outside the allowable range, the meter
remains in parameter setting mode and the value is set to
the highest possible value (when entered value is too high)
or lowest possible value (when it is too low).
