OPERATOR FUNCTIONS (RUN MODE)
4.1
DISPLAY BUTTON
The upper line on the display will always read % oxygen (or ppm, selectable in step 31 in
the set-up menu Section 5.5) for sensor 1. The following are available for display on the
lower line.
1. AVERAGE OF PROBE 1 & PROBE 2 OXYGEN,
2. PROBE 2 OXYGEN,
3. PROBE 1 EMF (millivolts)
4. PROBE 2 EMF (millivolts)
5. PROBE 1 TEMPERATURE
6. PROBE 2 TEMPERATURE
7. PROBE 1 IMPEDANCE,
8. PROBE 2 IMPEDANCE, A measure of integrity of the sensor's electrode, the part of the
probe that normally wears out first.
9. AUXILIARY TEMPERATURE
10.AMBIENT TEMPERATURE
11.OXYGEN DEFICIENCY %
12.COMBUSTIBLES %
13.% CARBON DIOXIDE, dry. Calculated from the oxygen reading. Assumes complete
combustion.
14.RUN HOURS SINCE LAST SERVICE
15.DATE OF LAST SERVICE
Any number of these variables can be displayed sequentially by pressing the 'DISPLAY'
button. Items can be selected for display or deleted in step 33, in the set-up menu Section
5.5, on the keyboard. In addition to the above lower line displays, the transmitter will
automatically display:
"Sensor 1 Temp Low", when sensor one is below 650°C (1200°F)
"Sensor 2 Temp Low", when sensor two is below 650°C (1200°F)
"Gas 1 ON", "Gas 2 ON" for Calibration check Gas 1 or 2
"Purging Probe"
"Sensor 1 Thermocouple Wrong Polarity"
"Sensor 2 Thermocouple Wrong Polarity"
"Aux Thermocouple Wrong Polarity"
NOTE:
1. The run time will be the period of time the BURNER ON SWITCH (terminals 18 & 19)
contact is closed (ie. main fuel valve open). If no explosion protection is required, a
permanent bridge between the BURNER ON SWITCH terminals will register run time
whenever the transmitter is powered.
2. This timer can be used as a probe replacement and/or boiler service schedule aid.
Changing the 'SERVICE DAY' in set-up mode on the keyboard resets the start time.
3. If you hold the display button down as you switch on the power, the maximum ambient
temperature which the instrument has been subjected to, will be displayed. This
temperature should be less than 50°C (130°F).
