COMMISSIONING
3.16 CONNECTING POWER
Before commissioning the probe, sensor or transmitter, read the CAUTION paragraphs at
the front of this manual. Check that the mains supply voltage switch is set for the correct
supply voltage, and that the green/yellow EARTH wire MUST be connected to earth.
3.17 COMMISSIONING - SET-UP MODE
Press the SET-UP button to select the ‘SET-UP’ mode. Most of the default settings of the
functions will be correct, or will have been pre-set at the factory. Refer to Section 5.5 for
more details.
Check the following set-up functions -
2 to 6 Date /time
7 to 10 Reference voltages
11 & 12 Probe offset
22 & 23 Sensor type
26 & 27 Output channel #1
28 to 30 Output channel #2
53 Auto purge
67 Auto gas calibration checking
70 to 78 Alarm set-up
3.18 COMMISSIONING - RUN MODE
When the transmitter is turned on it will go to RUN mode. The SET-UP/RUN button will
toggle between the two modes. The upper line of the display will now read ‘% OXYGEN’.
If the probe or sensor temperature is not above 650°C (1200°F), a “Probe Low
Temperature” message is flashed on the lower line. The probe or sensor temperature can
be checked on the lower line of the display.
3.19 BURNER BY-PASS SWITCH
Heated probes and sensors should have their heater supply interlocked. If the combustion
appliance is not running, then power will not be supplied to the heater. To commission an
oxygen probe when the main burner is turned off, switch power off the transmitter, remove
the probe from the flue or the flue connection from the 1234 sensor.
Re-apply power to the transmitter, press the BURNER BY-PASS switch into the ‘DOWN’
or ‘ON’ position. This will apply power to the probe or sensor heater even when the plant
is not running. The offset can now be set and calibration checked with appropriate
calibration check gases (typically 2% oxygen in nitrogen).
Ensure that the burner by-pass switch and the power are turned off before the probe or
sensor is re-installed. An alarm will occur if the BURNER BY-PASS switch is turned on
(down) during normal operation.
3.20 CHECKING THE ALARMS
If any alarms are present the alarm LED will be lit, either flashing or steady. To interpret
the alarms, press the alarm button until all alarm functions have been displayed. Rectify
