  • Page 5: Introduction

    INTRODUCTION General Description The Z1030 is a microprocessor controlled oxygen analyser based on a zirconia oxygen sensor. It provides a range of features and a performance without parallel for an analyser of this type and cost. Standard features include auto-ranging over a span of 100% to 0.01ppm, user programmable alarm levels, hysteresis and analogue output.

  • Page 8: Installation

    INSTALLATION Mounting The instrument should be installed where free air ventilation around the whole case is provided. The ambient operating temperature should not exceed the value stated in Section 3.13. Dust and dirt should be kept to a minimum. WARNING The sensor heater has a hot surface that is present in normal operation.

    180 mm Sensor Heater (approx) 35 mm to 50mm Figure 3 - Sampling system in wall-mounting enclosure Sample WARNING IT IS IMPORTANT THAT NO FLAMMABLE MIXTURES ARE ALLOWED TO COME INTO CONTACT WITH THE MEASURING CELL AS THIS MAY CAUSE IGNITION OF THE GAS.

  • Page 10: Electrical Connections

    Electrical connections For electrical and mechanical integrity, it is recommended that wires to all connectors are fitted with boot-lace ferrules. 3.3.1 Power supply Power connections should be made to the instrument using the connector provided. Take note of the supply voltage label on rear of the instrument. The power demand is approximately 24VDC maximum 1A at turn on.

  • Page 11: Sensor Connection

    3.3.3 Sensor Connection The sensor and instrument should be interconnected as shown in Table 1. Thermal compensation cable is recommended for connecting the thermocouple. NOTE A loose issue cable gland is supplied. The enclosure will need to be drilled to suit, according to customer requirements. Suggested location would be between the inlet and outlet ports.

  • Page 12: Commisioning

    COMMISIONING Applying power When the analyser is fully connected it may be switched on. The cell heater will begin to warm up. During this time the display will flash “HE xxxxx and the concentration display will make high and low excursions. Once the correct temperature is reached, the “HR” will end and the display will stabilise.

  • Page 13: Alarm 1

    4.2.2 Alarm 1 NOTE All alarm outputs will be in the ‘alarm’ state while the instrument is booting (for approximately 20 seconds after power on) or if the instrument registers an error, regardless of the alarm setting. 3P xxxx Where “xxxx” is the required concentration level setting that will trigger Alarm 1 - observe the “%”...

  • Page 15: Calibration

    CALIBRATION CAUTION Various procedures associated with calibration maintenance affect the outputs of the instrument. Any of these outputs that are being used for control (or the associated control loop) should be disabled before commencing. Calibration overview The Z1030 is a very stable analyser with minimal drift (see Section 3.5). The frequency of calibration checks or verifications depends upon the quality regime being operated at the installation site.

  • Page 16: Calibration Procedure

    Calibration procedure Refer to Figure 5: 1030 series menu on previous page. NOTE Calibration limits are set in the software to prevent the user from calibrating the instrument outside of the sensor’s operational range. If, on pressing the Cal button, the reading returns to the original value, the calibration has been rejected, and a change of cell is recommended.

  • Page 17: Spares And Repairs

    SPARES AND REPAIRS Should any failure occur, the instrument should be returned to your local MTL Gas sales office for repair. When ordering spare parts or raising queries on an instrument, it is important that the serial number is quoted. This will be found on the data label attached to the right-hand side of the instrument.

  • Page 18: Technical Description Of Sensor

    TECHNICAL DESCRIPTION OF SENSOR The zirconia oxygen sensor (see sketch below) is an impervious tube-shaped zirconia (zirconium oxide) element with a closed end coated externally and internally with porous metal electrodes, typically platinum. At high temperatures, typically above 400°C, the zirconia becomes an oxygen ion conductor, which results in a voltage being generated between the electrodes dependent upon the differences between the partial pressures of the oxygen in the sample and the oxygen in a reference gas (generally air).

  • Page 19: Communication Protocol

    COMMUNICATION PROTOCOL Communication parameters are 9600 Baud, 8 bits, no parity, 1 stop bit and no handshaking. The instrument is DTE. The general form of the protocol is: The protocol is a single command-and-response protocol. Multiple commands cannot be sent without waiting for a response. 2.
