  • Page 5: Application

    1. APPLICATION NA5 series meters with multicoloured bargraphs have an universal input desti- ned to measure temperature, resistance, voltage from shunts, standard signals, d.c. voltage and d.c. current. They can find application in various industrial fields, e.g. food industry, intermediate pumping stations, sewage treatment plants, chemical industry, weather stations, breweries. They are destined for the visualisation of the measured value and evaluation of change trends of checked technological processes. They can also find application in automation systems where programmed controllers are applied. Fig.1. View of the NA5 meter.

  • Page 6: Set Of The Meter

    NA5 meters can have in option: a continuous analogue output, a relay output, open collector (OC) type outputs and an RS-485 digital output. They are programmed by means of the keyboard and through RS-485. NA5 meters realise following functions: – measurement of the input quantity and displaying it on the display and the bargraphs, – recounting of the input signal into indication on the base of the individual linear characteristic, – arithmetical functions: raising to a power, extraction of roots, – programming of colours and bargraph resolutions, – signalling of alarm value setting exceedings, – recording of the measured signal in programmed time segments, – storage of maximal and minimal 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, – service of the RS-485 interface in MODBUS protocol, both in ASCII and RTU mode. 2.

    3. BASIC REQUIREMENTS, SAFETY INFORMATION Symbols located in this service manual mean: WARNING! Warning of potential, hazardous situations. Especially important. One must acquaint with this before connecting the NA5 meter. The non-observance of notices marked by these symbols can occasion severe injuries of the personnel and the damage of the instrument. CAUTION! Designates a general useful note. If you observe it, handling of the me- ter is made easier. One must take note of this when the instrument is working inconsistently to the expectations. Possible consequences if disregarded ! In the security scope the meter meets the requirements of the EEC Low-Voltage directive (EN 61010 -1 issued by CENELEC).

    5. SERVICING After connecting external signals and switching the meter on, its name and n100 also the current version of the program, e.g. . are displayed. After ca 3 seconds, the meter transits automatically into the working mode in which it carries out the measurement and the display of the measured value on the display and the bargraph. Depending on alarm parameter settings, the resolution and bargraph type, alarm thresholds are also displayed on the bargraph. The meter blanks automatically insignificant zeros. Key functions: 55-element bargraph (in three-colour execution) 29-element bargraph (in seven-colour execution) Upper alarm threshold Lower alarm threshold Display Acceptation key Escape key Value increasing key Fig. 4 Description of the NA5 frontal plate.

The pressure and hold down the key during 3 seconds causes the entry into the programming mode. The programming mode is protected by the safety code. The pressure and hold down the key during 3 seconds causes the entry into the preview menu and the menu of recorded values. One must move on the preview menu by means of the key. In this menu, only all programmed parameters except servicing parameters, are accessible to readout. The exit from the preview menu is operated by means of the key. It is also resl possible in the preview menu to review recorded values.

The pressure of this key longer than ca 2 seconds will cause the acceleration of the review. The pressure of the key in any moment will cause the lighting of the number of recorded results. The exit from the review of recorded values is operated by means of the key. The algorithm of the meter servicing is presented on the fig. 5. The appearance of the following symbols and inscriptions on the display means:...

  • Page 30 – The meter currently checks the value of the introduced parameter at the mo- ment. In case when the introduced value exceeds the upper or the lower range of changes given in the table 1, the meter will not make the parameter record. – In case of the Input type change, a simultaneous change of the decimal point follows, optimally for the given input. – After the supply decay, the current time is reset. – The recording switching off follows in following cases: switching the recording off from the programming matrix, change of the input type, change of the recording time start or the recording time interval, setting Cnt=0, filling of the memory, and at a renewed switching of the meter on to the network. – In case of a Intr or Sect bargraph type, it is possible to set only one CurL and Curh markers (from one alarm). The others are automatically erased. – Max and Min values are erased in case of changes: input type, individual cha- racteristic (on, off), writing of standard parameters. 6.
