Page 5: Safety Considerations
If such a situation is likely to occur you should ensure that the gases are drawn through a water-trap filter before they enter the sampler channels of the 1303. This will condense out water vapour in the gases and thus prevent condensation within the instrument. - Page 6 To ensure safe operation and retain the Type 1303 in safe condition, note the following: APPLYING POWER Before using the Type 1303, check that it is set to match the available mains voltage and that the correct fuse is installed.

Each of the 6 dosing outlet channels has a tube-mounting stub on the frontplate of the 1303. 6 tubes of up to 50m length connect each stub to the respective dosing point. -
Page 10: Front Panel
The doser system is set up for use by specifying a dosing time-out such that the 1303 will stop any current dosing procedure after a given time has elapsed without instruction from the controlling computer. This value is specified form the controlling computer. -

2.1.2 Connecting the Mains Supply The 1303 is operated from a 50 to 400 Hz single phase AC mains sup- ply. Before connecting the mains supply, the following checks and ad- justments should be performed to ensure safe operation of the 1303. -
Page 15: System Use
Mains Input connector to the mains supply using Power Cable (supplied with the 1303). 2.2 System Use The 1303 combines with the Gas Monitor and a controlling computer to provide a system which offers wide-ranging monitoring capabilities. The 1303 makes it possible to perform multi-point air-exchange analyses and multi-point monitoring tasks in many different situations and envi- ronments, without changing the system components. -
Page 16: Connecting The 1303 To The System Controller
Setting the Interface Address of the 1303 The 1303 uses a single interface address. The address is set using the bank of eight switches on the rear panel of the 1303. The last five switches on the bank decide the interface address. These switches are marked A1 (the least significant bit) to A5 (the most significant bit). - Page 17 If the switch is up, it represents a binary “1”. See Fig. 2.5. Fig. 2.5 Dipswitch settings binary “1” The interface address of the 1303 is set at the factory to 01111 (deci- mal value 15), see Fig. 2.6. If this is not suitable for your system, use the switches to set an address appropriate to your system.

Note: the performance of the 1303’s sampling and dosing systems are specified for sampling and dosing tubing of maximum 50m in length. Tubing for use with the 1303 is available from LumaSense, as follows: Sampler tubes, green nylon, LumaSense accessory number AF0006 or polytetrafluoroethylene (PTFE), LumaSense accessory number AF0614. -

Page 29: Installing Set-Up Parameters
The 1303 interface jobs Calibration_Data?, Dosing_Time_Out?, Mo- lecular_Weight? and Gas_Constant? are re-usable jobs; that is, when the data requested by this job is read-out from the 1303, the same job can be sent back to the system controller so that a different value for this parameter can be read-in to the 1303. -
Page 30: The Dosing Time-Out Parameter
(section 3.8.5). The range of possible values is from 10s to 3600s. If you do not specify a value for this parameter, the 1303 uses the default value of 60s. The dosing time-out is changed as follows. Examples: DOSING_TIME_OUT 30<LF> Changes the dosing time-out to 30s. -
Page 31: The Calibration Data Parameter
If the calibration data for each specific nozzle and for the tracer-gas currently being used is known, it can be sent directly to the 1303 using the following job, without calibrating the 1303. Note that the 1303’s doser nozzles must still be calibrated with each change of tracer-gas, so that the 1303 is able to calculate the amount delivered. -
Page 32: Calibrating The Doser System
Important! To ensure accurate calibration of the 1303, observe the following points before performing the calibration procedure. The 1303 must be placed in the area in which it will be used, with power on, at least 10 minutes before calibrating. This allows the... - Page 33 It is recommended that you read-out and note down the current calibration data for each nozzle, for future reference in the event of loss of calibration data from the 1303. The calibration data can then be re-installed using the Calibration_Data job, section 3.3.3.

2.3.5) and drawing the new sample. When the new sample has been drawn to the 1303, the internal 3-way valve is set to direct the sample to the Gas Monitor. The sampling pump stops, and the Gas Monitor’s pump draws the sample for analysis. -
Page 35: Using The Doser System
– see section 3.4 details of how to do this. The 1303 cannot open a dosing valve for which calibration data does not exist. To ensure efficient dosing, the tracer-gas pressure must be in the range 300 kPa to 450 kPa absolute. -

Page 38: Calculating The Dosage Delivered
Calculating the Dosage Delivered When each dosing-nozzle is calibrated with the tracer-gas being used (section 3.4) the 1303 is able to calculate the delivered dosage auto- matically. The delivered dosage is read-out from the 1303 as follows: Example: DOSAGE_GIVEN? 1<LF>... -
Page 39: Checking The 1303
If a bit is set, the 1303 is currently using the corresponding component. The flag is output from the 1303 as the total of the decimal equivalents of the binary values of the bits which are set. See Table 3.3... - Page 40 199 = 1 + 2 + 4 + 64 + 128. Therefore, bits 1, 2, 3, 7 and 8 are set. The mechanical con- dition of the 1303 is: dosing valves 1, 2 and 3 open; main dosing valve open; dosing pump running.

3.8.5 Reset_System Interface Job This interface job restarts the 1303. This job does not reset the 1303’s set-up parameters or calibration data. The 1303 restarts as described section 3.1. Resetting the 1303 cancels any task which the 1303 was performing prior to the reset. -
Page 42: The Status Byte
The status byte is an eight-bit byte, read out by the system controller as part of the serial poll sequence. The status byte gives the first indi- cation of the cause of the service request. The status byte for the 1303 is shown in Table 3.4. -
Page 43: Resetting The Status Byte
This job reads-out an 8-bit byte (the Warning Flags) which gives infor- mation about error conditions which affect the efficient operation of the 1303. The 1303 is still able to operate, but the error should be rectified as soon as possible. The Warning Flag byte is shown in Table 3.5. - Page 44 1303, or switching the 1303 off/on. Power Fail Flag Is set if the power from the 1303’s transformer to the 1303 is outside the range 13,25V to 15,75V. This flag is reset when the voltage is back within the above range, or by resetting the 1303, or switching the 1303 off/on.
- Page 45 This flag is reset by the next Check_System job (if the results of the check are satisfac- tory), or by resetting the 1303, or switching the 1303 off/on. If the er- ror is persistent, have the 1303 serviced.

Page 46: The Error? Interface Job
The Error? Interface Job This job reads-out an 8-bit byte (the Error Flags) which gives informa- tion 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. - Page 47 1303, or switching the 1303 off/on. Job Specification Error Is set if an interface job sent to the 1303 is not recognised. This can be due to an incorrect job header, incorrect syntax, or incorrect or missing data.

It is important to note that although the digital interface of the 1303 is designed according to IEEE Std 488 and follows the recommendations of IEEE Std 728, absolute compatibility with IEEE/IEC interfaces de- signed by other manufacturers cannot be unconditionally guaranteed, since differences can occur within the limits of the specifications. -
