USING THIS MANUAL
The Teledyne 9060 Oxygen Transmitter has a variety of user-selectable functions.
They are simple to use because each selection is menu driven. For options you are not
sure about; read the manual on that particular item.
Please read the safety information below and the ‘Installation’ section before connecting
power to the transmitter.
CAUTION 1
The probe or sensor heater is supplied with mains voltage. This supply has electrical shock danger to
maintenance personnel. Always isolate the transmitter before working with the probe or sensor, gas
solenoids, or the transmitter.
The EARTH wire (green) from a heated probe or sensor 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 cell type.
CAUTION 3
The oxygen sensor which is heated to over 700°C (1300°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 or sensor 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 or sensor then the Model 9060
Analyser with a heated probe or sensor 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 transmitter, normally incorporating a catalyst or thermal conductivity bridge, would be more
appropriate where incomplete combustion is possible.
Also read the probe or sensor electrical shock caution in Section 2.5 and the probe or sensor heater
interlock caution in Section 3.6.
CAUTION 5
If an external pressure transducer is used to feed the process pressure to the transmitter for pressure
compensation, it is essential that the pressure transducer is accurate and reliable. An incorrect reading of
pressure will result in an incorrect reading of oxygen. It is therefore possible that an explosive level of fuel
could be calculated in the transmitter as a safe mixture.
CAUTION 6
FIL-3 filter. If the optional FIL-3 has been fitted to the 1231 probe in this installation, please read the
Important Notice in section 1.2.
