1. APPLICATION

NA6Plus series meters with a bar graph have a universal input designed to measure temperature,

resistance, voltage from shunts, standard signals, DC voltage and DC current. They can be used in

various industries, such as: food industry, pumping stations and sewage treatment plants, chemical

industry, weather stations, meteorological stations, breweries They are intended for the

visualization of the measured quantity and evaluation of change trends of controlled technological

processes. They can also be used in automation systems where programmed controllers are

applied.

NA6Plus meters have, depending on the version, one or two continuous outputs (voltage or

current), 4 relay outputs or 8 open collector (OC) type outputs, as well as an RS-485 interface. The

meters are programmable via the keyboard and via RS-485.

NA6Plus meters performs the following functions:

measurement of the input quantity and displaying it on the display and the bar graph,

recalculating of the input signal into indication on the base of the individual multipoint

characteristics,

arithmetic on the channels: addition, subtraction, multiplication, division, power and

square root;

programming of colours and bar graph resolutions,

signalling of exceeding the set alarm values;

recording of the measured signal in programmed time intervals,

storage of maximum and minimum values,

programming of the measurement averaging time,

programming of the indication resolution,

deadlock of the parameter introduction by means of a password,

conversion of the measured quantity into a voltage or current output signal,

RS-485 interface support in MODBUS RTU protocol.

duly qualified electrician.

The person performing the installation is responsible for the safety of the system in which

devices is installed.

Before turning on the module, verify the connections.

Removal of the meter housing during the warranty period voids the warranty. The module

power supply must be turned off and the input circuits disconnected before opening the

housing.

The device is intended for installation and use in industrial electromagnetic environments.

A switch or a circuit-breaker should be installed in the building or facility. It should be

located near the device, easily accessible to the operator, and suitably marked.

In the event of damage, the meter can be repaired only by the service authorized by the

manufacturer.

Before using the repaired meter make sure that it is working properly.

Connection of the meter and/or its usage inconsistently with this manual can reduce the

operational safety of the meter.

4. INSTALLATION

4.1. Installation

The NA6Plus meter is designed to be mounted on a panel. For this purpose, a 44.0 x 137.5 mm

hole should be prepared in the panel. The thickness of the material from which the panel was

made should be in the 1.45 mm range.

In the back of the meter housing there are detachable terminal strips, enabling connection of power

supply, input signals, output signals and RS482 interface with wires with a cross-section of up to

2.5 mm2. The dimensions of the meter are shown in Fig. 2.

The connections of the meter are shown in Figure 3. In the event when the meter is powered with

DC voltage, the voltage polarity does not matter.

Taking into consideration electromagnetic interference it is recommended to use shielded

conductors for the connection of input and output signals. The power supply must be connected by

means of a two-wire conductor with a suitable cross-section ensuring its protection by means of an

installation fusible cut-out, in case of a short-circuit.

The requirements concerning the supply cable are regulated by EN 61010-1 p.6.10 standard.

5. Operation

After connecting external signals and switching on the power supply, the meter displays the type

and current version of the meter program.

After ca 3 seconds, the meter switches automatically to the operating mode in which it carries out

measurements and displays the measured value on the display and the bar graph. Depending on

alarm parameters settings, the resolution and bar graph type, alarm thresholds are also displayed

on the bar graph. The meter blanks automatically insignificant zeros.

Pressing and holding the key for about 3 seconds causes entering the programming mode.

The programming mode is secured with the  security code.

Pressing and holding the key for about 3 seconds causes entering the menu of the preview

and the menu of recorded values. Navigating the preview menu is done using the key.

In this menu, all programmable parameters of the meter are available for read-out, with the

exception of service parameters. The exit from the preview menu is done by means of the

key.

An overview of the recorded values is possible after pressing the key on the 

parameter in the preview menu. The recorded result number is displayed alternately

with the value e.g. /. Navigating the recorded values is done using the key.

Holding this key for longer than about 2 seconds will speed up the browsing. Pressing the

key at any time will display the number of recorded results. The exit from the viewing recorded

values is done by pressing the key.

5.1 Changing meter parameters from the keyboard

Pressing the key for approx. 3 s causes the display of the  message alternately with the

factory-set value of 0. Entering the correct code results in entering the programming mode. Figure

8 shows the transition matrix in the programming mode. The key allows for moving around

the main parameters groups, e.g.: Ch1, Ch2, bAr1, bAr2, AL1, AL2, etc. Pressing the key

on the given level, causes the entry into parameters of this level. Moving around a given level

takes place by means of the key . To change the value, use the . To cancel the

parameter change, press the key . The same key is used to exit the selected level and

programming matrix to the measurement.

The transitions matrix in the programming mode is shown in Figure 9.

During operation of the meter in the programming mode, the measurement result is displayed on

the bar graph, except for selecting the display test function.
