    1. APPLICATION AND METER DESIGN The N30H meter is a programmable digital panel meter destined for the measurement of d.c. voltage or d.c. current. Additionally, the meter enables the indication of the current time. The readout field is a LED display, which allows the exposition of results in colours: red, green and orange.

    3. BASIC REQUIREMENTS, OPERATIONAL SAFETY In the safety service scope, the N30H meter meets the requirements of the EN 61010-1 standard. Observations concerning the operational safety All operations concerning transport, installation, and commissioning as well as maintenance, must be carried out by qualified, skilled per- sonnel, and national regulations for the prevention of accidents must be observed.

  • Page 8: Installation

    4. INSTALLATION The meter has separable strips with screw terminals, which enable the connection of external wires of 2.5 mm cross-section. Strips of input signals are protected against any accidental disconnection by means of a screw joint. ´ 45 One must prepare a hole of 92 +0,6 +0,6 mm in the panel, which the...

Analog outputs are not separated between them. One don’t have to take simultaneously advantage of voltage and current measure- ments, since measuring circuits of voltage and current are not galva- nically isolated.

  • Page 22 5.4.4 Individual Characteristic N30H meters can recalculated the measured value into any value thanks to the implemented individual characteristic function. The indivi- dual characteristic rescales the input signal measured according to the set characteristic. The way of the individual characteristic interaction on the meter operation has been presented on the fig.10.
  • Page 23 Fig. 11. Individual characteristic During the function approximation, one must remember that for the ap- proximation of functions strongly differing from the linear characteristic , the higher the number of linearizing segments, the smallest the error related to the linearization. If measured values are smallest from H1 then, recalculations will be made on the base of the first straight line calculated on the base of points (H1,Y1) an (H2,Y2).
  • Page 24 5.4.5 Alarm Types The N30U meter is equipped with 2 alarm outputs with NOC contact (make contact) and two alarm outputs with NOC/NCC contact (make and break contact) (option). Each of alarms can work in one of the six modes . The work of alarms in modes is presented in the fig. 12. : n-on, n-off, on, off.
  • Page 25 5.4.6 Display Format The N30H meter adapts automatically the display format (precision) to the value of measured quantity. So that the function could be fully used, one must choose the format 0.0000, then the meter will display the me- asured value with the possible highest accuracy.

  • Page 27: Rs-485 Interface

    6. RS-485 INTERFACE N30H programmable digital meters have a serial link in RS-485 stan- dard for the communication in computer systems and with other de- vices fulfilling Master function. An asynchronous communication cha- racter protocol MODBUS has been implemented on the serial link. The transmission protocol describes ways of information exchange between devices through the serial link.
  • Page 28 The lead wire of the interface line is presented on the fig. 4. To obtain a correct transmission, it is necessary to connect lines A and B in parallel with their equivalents in other devices. The connection must be made through a shielded wire.
  • Page 29 6.2. Description of the MODBUS Protocol Implementation. The implemented protocol is in accordance with the PI-MBUS-300 Rev G of Modicon Company specification. Set of the serial link parameters of N30U meters in MODBUS protocol: meter address: 1...247, baud rate: 4800, 9600, 19200, 38400, 57600, 115200 bit/s, work mode: RTU with a frame in formats: 8N2,...

  • Page 41 7. SOFTWARE UPDATING The N30H meters (from the version 1.09) in version with RS-485 interface come with the implemented function that allows for updating the software from a PC with LPCon or eCon software. In order to update software the RS-485 converter on USB, such as PD10 converter must be connected to the computer.
  • Page 42 Entering the updating mode in the meter is carried out remotely by LU program (based on the settings in LPCon - adres, mode, baud rate, port Com) or by switching on the meter power supply with pressed key . Pulsating of the meter state diode AL1 in gre- en signals readiness for updating, whereas the LU program displays the message Device found and the name and version of the program of the conneted device.
