1. APPLICATION AND METER DESIGN

The N21 meter is a digital programmable panel mounted instrument

designed to measure d.c. voltages or d.c. currents: unipolar or bipolar,

temperature with use of thermocouples J (Fe-CuNi), K (NiCr-NiAl)

and Pt100 resistance thermometers. The readout field is an OLED

graphic display with a resolution of 32x128 points.

The eCon program is designed for the configuration of the N21 meter.

The meter should be connected to a PC via a miniUSB connector

located on the rear of the meter. Following parameters can be set:

• measuring input

• display precision of the result (decimal point)

• relay output operating mode

• thresholds triggering the relay output

• time delays of the relay output triggering

• individual characteristic for measuring signal

• automatic or manual temperature compensation of cold junctions

• averaging time of the measurement

• user-defined units of measured signal

• display language

• bargraph configuration.

Meter output signals are isolated from the input signals and power supply.

3. BASIC REQUIREMENTS,

OPERATIONAL SAFETY

The symbols in the manual mean:

Warning!

Warning of potentially hazardous situations. Especially

important to be aware of before connecting the device.

Failure to follow the directions marked by this symbol

could result in serious injuries of the personnel and dama-

ge of the device.

Caution!

Useful notes. The notes should facilitate the operation

of the device. Should pay attention, if the device is not

working as expected.

Possible consequences in case of ignoring informa-

tion!

Accessories:

For the N21 meter you can order:

– USB CABLE A/miniUSB-B - 1m BLACK; Order code 20-069-00-

00150.

In terms of operational safety the meter meets the requirements

of the EN 61010-1 standard.

Comments concerning safety:

• Assembly and installation of the electrical connections should be

made only by people authorized to perform assembly of electric

devices.

• The person installing the meter is responsible for ensuring

the safety of the implemented system.

• Always check the connections before turning the meter on.

• Opening the meter housing gives access to the live parts.

The supply must be switched off and the measuring circuits discon-

nected before removing the meter housing.

• Removal of the meter housing cover during the warranty period

voids the warranty.

• The meter is designed to be installed and used in the industrial

electromagnetic environment conditions.

• The building installation should have a switch or a circuit-breaker

installed. This switch should be located near the device, easy

accessible by the operator and suitably marked.

• In case of damage, the meter can to repaired only by manufacturer’s

authorized service.

• Check the correct operation of the meter before it is used for mea-

suring after a repair.

• Connection and/or using the meter in a way which is not compliant

with the user’s manual, may cause deterioration of the degree

of protection.

4. INSTALLATION

4.1. Mounting

The N21 meter has separable strips with the screw terminals which

enable the connection of external supply wires of 2.5 mm2and signal

wires of 1.5 mm2.

You must prepare a 92+0,6 x 45+0,6 mm cut-out in the panel. The thi-

ckness of the panel material should not exceed 6 mm. The meter

should be mounted from the panel front with disconnected supply volta-

ge. Check the correct position of the seal before placing the meter into

the panel. When the panel is inserted in the slot, mount it in the panel

with the mounting brackets (Fig. 2).

Comment concerning safety:

The meter is provided with a universal power supply that allows

operation in a wide range of input voltages 22..253V a.c / 20..300V d.c.

Life-threatening voltage also appears at the terminal 12 of the meter

in the case of the use of the input terminals 13-14.
