14. MAINTENANCE
14.1 TRANSMITTER MAINTENANCE
The 9060Z transmitter has several hardware checking systems that confirm the correct operation of
the transmitter and raise an alarm if there is a fault detected. Because of this system, the transmitter
only requires periodic maintenance. Teledyne Analytical Instruments recommends an annual check of
the transmitter.
The annual check should include the following items –
1. Measure and record the reference voltages, and check that the correct voltages are set in the
calibration menu
2. Check that the reference air flow from the port on the bottom of the transmitter case is between
100 and 300cc/m
3. Check for contamination and potential blockage of the reference air filter that is mounted on the
bottom of the transmitter case
4. If an external burner interlock has been connected (terminals 10 & 11), check that if one of the
wires is disconnected the probe heater is disabled (9060H probes only)
5. Check the integrity of the cable. Particularly check the main power supply cable and the probe
cable for any damage.
6. Check the integrity of the earth connections in the transmitter
14.2 CLEANING
The 9060Z transmitter is made in an IP65 / IP54 rated diecast case. It is painted with a tough ripple
finish power coating to maintain a clean look. However, if it is necessary to clean the case use either a
warm soapy water solution or an isopropyl alcohol.
A build up of dust on or around the transmitter should be removed before the cabinet door is opened.
If there is a buildup of dust inside the cabinet check the door o‐ring seal for damage and replace it if
necessary.
Take care when wiping the display window to avoid scratching the surface.
If the filters of the probe (if fitted) become blocked, use an ultrasonic cleaner with a few drops of
household detergent. If the filters cannot be cleaned this way replace the sintered filters.
The filter in the base of the analyzer may become blocked if the analyzer is operating in a dusty
environment. It is available as a field replacement item.
