1. USING THIS MANUAL
This manual is a shortened version of the 1732 Oxygen Transmitter product manual to be used by the
operator. It does not cover the commissioning, calibration or servicing of the 1732 Oxygen Transmitter. If
more detailed information is required than what is provided in this manual please refer to the more detailed
1732 Oxygen Transmitter Technical Manual. Both manuals are supplied with each transmitter and are also
available to download at the Novatech Controls website.
http://www.novatech.com.au/1732
It is assumed in this manual that the transmitter has been installed by qualified personal and that the wiring
to the main power supply, the oxygen probe and all the associated signal devices complies with the local
safety codes and regulations.
1.1 Cautions
Please read the safety information below before connecting power to the transmitter.
CAUTION 1
The probe heater is supplied with MAINS VOLTAGE. This supply has electrical shock danger to
maintenance personnel. Always isolate the transmitter before working with the probe.
The EARTH wire (green) from a heated probe must ALWAYS be connected to earth.
CAUTION 2
Combustion or atmosphere control systems can be dangerous. Burners must be mechanically set up so that
in the worst case of equipment failure, the system cannot generate explosive atmospheres. This danger is
normally avoided with flue gas trim systems by adjustment so that in the case of failure the appliance will not
generate CO in excess of 400 ppm in the flue. The CO level in the flue should be measured with a separate
CO instrument, normally an infrared or fuel cell type.
CAUTION 3
The oxygen probe is heated to over 700°C/1290°F and is a source of ignition. Since raw fuel leaks can
occur during burner shutdown, the transmitter has an interlocking relay that removes power from the probe
heater when the main fuel shut-off valve power is off. If this configuration does not suit or if it is possible for
raw fuel to come into contact with a hot oxygen probe then the Model 1732 transmitter with a heated probe
will not be safe in your application.
An unheated probe can be utilised in such applications, however the oxygen readings are valid only above
650°C/1200°F.
CAUTION 4
The reducing oxygen signal from the transmitter and the associated alarm relay can be used as an explosive
warning or trip. This measurement assumes complete combustion. If incomplete combustion is possible
then this signal will read less reducing and should not be used as an alarm or trip. A true excess
combustibles analyser, normally incorporating a catalyst or thermal conductivity bridge, would be more
appropriate where incomplete combustion is possible.
Also read the probe electrical shock caution in the probe heater interlock caution in chapter 4.7 of the Model
1732 Technical Manual.
CAUTION 5
FIL-3 filter. If the optional FIL-3 has been fitted to the 1231 probe in this installation, please read the
Important Notice in the Technical Manual.

ALARM ∇
When the transmitter is displaying active alarms (the ALARM ∆button has been pressed), the ALARM ∆button
and ALARM ∇button allow the operator to examine the date / time of the alarm and the date / time that the
alarm was acknowledged.
ALARM ACCEPT
Press this button to acknowledge the currently displayed alarm (see Chapter 6. Alarms).
GAS 1/PURGE 1GAS 2/PURGE 2
These two buttons are used to turn on the gas / purge solenoids. When the transmitter is in the manual cal /
purge mode (Commissioning Menu function #23/32) the solenoid will be activated for as long as the button is
pressed. When the transmitter is in the auto cal / purge mode the automatic cal / purge cycle is started. The
cycle can be stopped by pressing the same button again. (see Chapter 7. Gas Calibrate and Purge)
4.3.2 Keypad in the Setup Menu
From Run Mode, if the SETUP /RUN button is pressed once, the transmitter will display the Setup Menu. For
information about accessing the Commissioning Menu or Calibration Menu see the 1732 Technical Manual.
The following functions are then available in the Setup Menu.
SETUP /RUN
Pressing this button while in the Setup Menu will return the transmitter to the Run Mode.
FUNCTION ∆/FUNCTION ∇
These two buttons allow the selection of the Setup Menu function. A function summary table is found at the
start of Chapter 5.1 Setup Menu.
OPTION ∆/OPTION ∇
These two buttons allow for modifying the option for the selected function. A list/range of options for each
function is found in Chapter 5.3.
ENTER
This button applies/updates the currently displayed option and stores the value in non-volatile memory to be
retrieved on device start up. If this button is not pressed before changing to a new function then the previous
option will be retained.
SENS IMP
When this button is pressed the transmitter will measure the impedance of oxygen probe(s) attached to the
transmitter. If the burner is not enabled (terminals 10 & 11) or the probe temperature is below 700°C
(1292°F) impedance checking will not be performed. During impedance checking a ‘Z’ will be seen in the
bottom left hand corner of the display.
AUTO CAL
When this button is pressed the transmitter will calibrate the analog output channels that are set to auto
calibration. This is performed by directing the output current away from the output terminals (terminals 12
&13 and 14 & 15) and back the current back into the transmitter input. The transmitter will then calculate a
zero and a span calibration factor for each of the output channels. The output calibration will only happen if
the channel is not set to manual output calibration. (see 1732 Technical Manual for more details)
During this process normal output to the analog channels will be interrupted sending the outputs open circuit.

5.3 Setup Menu Functions
5.3.1 Probe 1 & Probe 2 Offset
Options: ±6.0mV in 0.1mV increments
Default: 0.0mV
Each Novatech oxygen probe has an offset calibration value printed on a tag that is attached to the probe
when it is dispatched. To achieve the most accurate measurement of oxygen the offset value must be
entered into this setup function with the same polarity as it is printed on the label. For a healthy probe the
offset value should be within ±1.0mV.
NOTE: An offset of 1.0mV will change the oxygen reading by approximately 1% oxygen when the probe is in
ambient air. However, as the process oxygen measurement drops, this offset will have a diminishing effect.
At a process gas oxygen concentration of 2%, the 1.0mV offset error will only change the reading by 0.1%
oxygen. If in any doubt about the correct offset value, set it to 0.0mV.
The function ’Probe 2 Offset’ will only appear if the transmitter has been configured for 2 oxygen probes.
5.3.2 Lower Line Items
This function allows the operator to change the items that are available to be displayed on the lower line of
the transmitter in Run Mode. If the word “Enabled” appears on the display for a selected lower line option,
the measurement will be available to be shown on the display in the Run Mode by scrolling through the list
using the DISPLAY ∆and DISPLAY ∇buttons.
Each individual lower line measurement can be enabled or disabled by pressing the ENTER button.

5.3.3 Oxygen Display Units
Options: Oxygen % / Oxygen ppm
Default: Oxygen %
The top line of the display that shows the oxygen measurement can be displayed in either % or parts per
million (ppm)
5.3.4 Damping Factor
Options: No Damping
1 to 10 Samples Averaged
Default: 5 Samples
The oxygen measurement can be damped by averaging successive readings from the probe. This can be
used to smooth out fluctuations in the process gas level and should improve stability of the readings of the
system The larger the number selected here, the more successive readings are averaged and the smoother
the measurement will be.
The damping factor is not applied to the Probe EMF and Probe Temperature values used to calculate
oxygen, but to the oxygen value itself. The pre-damped oxygen value is not displayed or retransmitted via
digital or analog outputs, when damping is enabled the damped oxygen value is shown on the local display
as well as being retransmitted via digital or analog outputs.
5.3.5 Process Alarms
Options: Enabled / Disabled
