Chapter 3 ________________________________________________________________________ All tasks performed by the 1303 are controlled over the IEEE/IEC interface from a computer; there is no other control possibility. This chapter deals with the control of the 1303 from the user’s point of view; for details of the IEEE/IEC interface specifications, refer to Chapter 4 of this manual. Sections 3.1 and 3.2 deal with switching-on and the general principles of controlling the 1303. Sections 3.2 to 3.
Chapter 3 ________________________________________________________________________ Fig.3.1. General syntax diagram for interface jobs Job Headers The job header specifies the function you want the 1303 to perform. It consists of one or more words. The ASCII underline character “_” is used to separate individual words in the job header. For example: OPEN_SAMPLING_VALVE A hyphen “-“ or a full stop”.” can also be used to separate words in the job header.
Chapter 3 ________________________________________________________________________ OPEN_SAMPLING_VALVE 2,3,4 Numerical data for interface jobs sent to the 1303 can be in NR1, NR2 or NR3 form. This is a format for describing how the numerical data is represented, for example: NR1 data: 250 (number without decimal-fraction or exponent) NR2 data: 249.85 (number with decimal fraction, without exponent) NR3 data: 2.499E-2 (number with fraction and exponent).
Chapter 3 ________________________________________________________________________ Table 3.1. The range of ASCII terminator-characters which can be used in communication with the 1303 ASCII Character SOH STX ETX EOT ENQ ACK BELL BS HT LF VT FF SO SI DLE 3.2.
Chapter 3 ________________________________________________________________________ Generally, numerical data output from the 1303 is in NR2 form unless specifically stated otherwise in the interface job overview given in section 4.2. The default terminator character used is the control character “”. The terminator character can be changed, as described in section 3.2.1.
Chapter 3 ________________________________________________________________________ 3.3.1 The Dosing Time-out Parameter This value specifies the maximum time for which the 1303 will deliver tracer-gas without receiving further instructions about the dosing task from the system controller. When the time period specified by the dosing time-out is exceeded, the 1303 stops delivering tracer-gas, and sets the Dosing Nozzle Flag in the Warning Flags byte (section 3.8.5).
Chapter 3 ________________________________________________________________________ Alternatively, the gas constant can be expressed in terms of the molecular weight of the gas: MOL_WEIGHT 146,05 Sends the gram molecular weight 146,05 (for SF6 ) to the 1303.
Chapter 3 ________________________________________________________________________ Example: CALIB_DATA 1,1.25 Sets the calibration data of number 1 dosing nozzle to 1.25. To avoid having to calibrate each dosing nozzle after each time the 1303 has been switched off, it is recommended that the calibration data for each nozzle is read-out and noted for future reference. The calibration data for a specific nozzle can be checked using the following job.
Chapter 3 ________________________________________________________________________ 1303’s temperature to stabilize in relation to the temperature of the area in which it will be used. The main dosing valve and each dosing valve must be opened to allow tracer-gas to flow into the 1303’s dosing manifold, for 5 minutes before calibrating. This ensures that the temperature of the dosing system will stabilise relative to the temperature of the tracer-gas.
Chapter 3 ________________________________________________________________________ 3.5 Using the Sampler System Using the 1303’s sampler system (see Fig. 1.1), to deliver a sample to the Gas Monitor is a 3-stage process: 1. The required sample valve is opened; all other sample valves are closed automatically. The sampling pump starts. 2.
Chapter 3 ________________________________________________________________________ limits. The pressure across the sampling pump can be checked to ensure efficient gas-transport; see section 3.8.1 for details. The sampling pump can be controlled using the following jobs: SAMPLING_PUMP ON Starts the sampling pump. SAMPLING_PUMP OFF Stops the sampling pump. 3.
Chapter 3 ________________________________________________________________________ MAIN_DOS_VALVE OP Opens the main dosing valve to allow the flow of tracer-gas to the dosing valves. The main dosing valve will close automatically to protect the dosersystem airways if the tracer-gas pressure in the dosing manifold is above 550 kPa absolute. 3.6.3 Starting Continuous Dosing Using the interface job described below starts an uninterrupted flow of tracer-gas through the specified dosing valves.
Chapter 3 ________________________________________________________________________ system is higher than 125kPa. The pump operates for one minute, then stops for one minute, then operates for one minute, and so on. Example: DOSING_PUMP AUTO 3.6.4 Runs the carrier-air pump for one minute, at one minute intervals, whenever the pressure in the 1303’s doser system rises above 125kPa.
Chapter 3 ________________________________________________________________________ DIS_DOSING 3,60,6,2 Starts a discontinuous dosing procedure through dosing valve number 3 for a total time of 60s. The discontinuous dosing period-length is 6s, during which the dosing valve is open for 2s. 3.6.5 DIS_DOSING 1,20 Starts a dosing procedure in which dosing valve number one is open continuously for 20s.
Chapter 3 ________________________________________________________________________ 3.8 Checking the 1303 These interface jobs are for checking the various functions of the hardware and software components of the 1303, and help to identify faults in the 1303. 3.8.1 Sampling_Pump_Pressure? Interface Job This job reads-out the pressure-difference across the sampling pump. The pressure across the pump can be measured with the sampling valves either open or closed.

Value Flag Description 1 Reset Done Flag 2 Temperature Flag 4 Power Fail Flag 8 Sampling System Flag 16 Dosing Filter Flag 32 Dosing Nozzle Flag 64 Dosing Pump Flag 128 Calibration Flag Warning Flags are set when either the 1303’s self-check procedures or the Check_System interface job identify an error condition.
Chapter 3 ________________________________________________________________________ Sampling System Flag Is set if, during the self-test specified in test 3 of the Check_System job (section 3.8.4) the pressure across the pump is less than 40kPa. This indicates that either the sampling pump is not working correctly, or that the sampler system is not sufficiently air-tight.
Chapter 3 ________________________________________________________________________ 3.9.5 The Error? Interface Job This job reads-out an 8-bit byte (the Error Flags) which gives information about errors which cause the 1303 to stop working. If any of these errors exist, the 1303 is unable to function until the error is rectified. The Error Flag byte is shown in Table 3.6. Table 3.6 The 1303’s Error Flags byte Bit no. 1 2 3 4 5 6 7 8 ERROR FLAGS Dec.
Chapter 3 ________________________________________________________________________ RAM Flag Indicates that the RAM (random access memory) of the 1303, which stores the 1303’s set-up data, has been corrupted. The flag is reset by switching the 1303 off/on. If the error persists, have the 1303 serviced. PROM Flag Indicates that the CRC (cyclic redundancy check) for the PROM (programmable read-only memory) has identified incorrect data. The flag is reset by switching the 1303 off/on.
Chapter 3 ________________________________________________________________________ up memory has been corrupted, or the 1303 has been switched off/on. The 1303’s set-up parameters will revert to their default values. This flag is reset by reading-out the Error Flags. If the error persists, have the 1303 serviced.
