    Wiring Methods (NEC Sec 501.4(b) or CEC 18-152) and in Accordance with the Authority Having Jurisdiction. If the 3050-OLV is to be powered by a source of 24 VDC other than that supplied by AMETEK, the power source’s output must be isolated from hazardous mains voltages by use of double or reinforced insulation, having a minimum dielectric strength 2300 VAC.

  • Page 10: Electromagnetic Compatibility (Emc)

    The various configurations of the 3050-OLV Analyzer should not produce, or fall victim to, electromag- netic disturbances as specified in the European Union’s EMC Directive. Strict compliance to the EMC Directive requires certain installation techniques and wiring practices be used in order that erratic behavior of the Analyzer, or its electronic neighbors be prevented or minimized.

  • Page 13: Overview

    Overview The 3050-OLV Moisture Analyzer measures trace concentrations of moisture in a process gas stream. The 3050-OLV is compatible with He, Ar, Ne, Xe, Kr, O , NO, CO, CO , light hydrocarbons, natural gas, refrigerants, air, and specialty gases. Refer to Figure 1-3 for a Gas List. The analyzer is calibrated to measure moisture contents from 0.1–2,500 PPMV.

    One RS-232 serial port. • One RS-485 serial port. The 3050-OLV has no local user programming functions. It requires serial communication with an external PC for configuration. Once configured, the analyzer is capable of standalone operation. The analyzer is factory configured and packaged with Configurator Software for initial setup of operating param- eters.

  • Page 16: Verification

    Verification The 3050-OLV has a built-in Moisture Generator for onboard Verification. A portion of the dry Reference gas flows through the Moisture Generator where a known amount of moisture is added. When Cell Verification is initiated, the QCM sensor is alternately exposed to gas from the Moisture Generator and dry Reference gas.

  • Page 17: Dewpoint Conversions

    A second consideration, when using the 3050-OLV Analyzer to calculate dewpoint/frostpoint temperatures, is the sample (i.e., the process) pressure. The range of process pressures allowed by the 3050-OLV is restricted for many sample gases. Many gases liquefy at relatively low pressures, so calculating a dewpoint/frostpoint temperature for these compounds has no value.

The variable called SerialMode allows switching communication protocol from AMETEK ASCII to Modbus protocol and back from Modbus to AMETEK ASCII. This variable can be reached from AMETEK ASCII protocol by ID=38(26Hex) and SerialMode can be modified by modifying holding register #28(4029), as indicated in the holding registers table.
  • Page 88 Power should be cycled Off-On or a reset command should be issued to activate the change in the serial mode setting. It is strongly recommended to conFigure and to test 3050 Analyzer in AMETEK ASCII mode using user-friendly 3050 Configurator Software. The Modbus RTU protocol mode should be used for monitoring purposes.

    Analyzer Modbus Interface Parameters A number of analyzer Modbus interface parameters need to be set up in order to establish communication with the Modbus master. These parameters are accessed via the service port on the analyzer using a service program running on a PC.

  • Page 91: Holding Registers

    Holding Registers Since the RAM space on the analyzers is limited and not every customer’s DCS\SCADA\DAS\PLC supports Modbus floating point value transfer, floating point values that are commonly accessed on a 3050 Analyzer are scaled and converted into integer values to load into Modbus registers for transmission. The Register values need to be scaled back at the receiving end to yield the actual values.

  • Page 95 Register #0 holds the moisture concentration value not held during Verifica- tion. This value is in PPM. A pair of registers #135 and #136 provide the same moisture concentration value in floating point Modicon standard. Register #1 holds the moisture concentration value held during Verification. The units of measurement are changing depending of flag status located in register #65.

  • Page 96: Id/Status Information

    The Modbus master can poll the analyzer periodically for status information via Modbus function 17 (11Hex). The returned information has the following format: 1 byte Slave ID = 50h for 3050-OLV Analyzer 1 byte Run Status = FFh for Analyzer Online (invalid signal = 0)
