20. Probe TypeOptions:Model No.Enter the probe model number in use1. 1231 / 1234 Heated * Heated Probe2. 1232 Unheated Unheated Probe21. Probe Thermocouple Type22. Auxiluary Thermocouple TypeThe probe can have either a type K, or R thermocouple as a sensor temperature detector. A 1231 probe or a 1234sensor will always have a K thermocouple, and a 1232 will usually have an R thermocouple.Options:1. K Check in the manual Section 12. R for the probe model number.3. NO T/C * If no TC type is to be used for an Auxiliary use.NOTEFor heated probes, the flue (auxiliary) thermocouple is a separate sensor from the oxygen probe. If no thermocouple isrequired, select option ‘NO T/C’. In this case auxiliary temperature read outs will not be operable.23. Transmitter Output Channel 1Select the type of output required from Channel 1. Linear is the most common output required. The logarithmic outputis often used when connected to an analog indicator that will then give an exploded view of the oxygen range near thenormal operating level. You can draw your own scale using data in Appendix 3.Options:1. Linear oxygen *2. Logarithmic oxygen3. Reducing oxygen, Range fixed at 10 -1 to 10 -30 % oxygen4. Reducing oxygen, Range fixed at 10 +2 to 10 -4 % oxygen (100% to 1 ppm)5. Very low oxygen (1 ppm to 10,000 ppm, 1%)6. Oxygen deficiency (-5% to +10% oxygen)Linear output spans are adjustable in Set-up step 24.The reducing output is for special applications requiring extreme reducing conditions eg. ceramic surface treatment.The logarithmic output is fixed at 0.1 to 20 % oxygen and the reducing output is fixed at either 10 -1 to 10 -30 % oxygen or10 +2 to 10 -4 % oxygen.The oxygen deficiency scale can be used to follow the normal oxygen level, but also track any excursions into the fuelrich operation.If any of the latter four are selected, set-up 24 will be skipped.24. Transmitter Span Channel 1Applicable only to linear outputs. Select transmitter span for output Channel 1. For combustion applications, typicallinear spans are 0 to 10 % or 0 to 21 % oxygen.Default setting is 10.0%.25. Transmitter Output Channel 2Select transmitter output for output Channel 2.Options:1. Oxygen Sensor EMF *2. Logarithmic oxygen, 0.1 to 20 %3. Auxiliary (Flue) temperature4. Linear oxygen %5. 1 x 10 +2 to 10 -30 % oxygen, for reducing conditions.6. Efficiency7. CO 2 maximum8. Combustibles %26. Transmitter Zero Channel 2The output zero and span of Channel 2 is set in set-up steps 25 and 27. Range limits are shown below.August 200948 1633 Combustion Controller
