16. 'Probe 1 Filter Blocked'
17. 'Probe 2 Filter Blocked'
Blocked probe filter. This test is only performed when automatic purging of the probe is selected. Refer to
the 1732 Technical Manual for further details. This alarm will not reset until the next purge cycle that can be
initiated manually or automatically, or the power to the transmitter is turned off and back on.
18. 'Gas 1 Calibration Error'
19. 'Gas 2 Calibration Error'
This alarm will only be raised if the oxygen measurement during an automatic gas calibration check falls
outside the set gas % limits. This alarm will not reset until the next purge cycle that can be initiated manually
or automatically, or the power to the transmitter is turned off and back on.
6.4 Selectable Process Alarms
There are three user configurable alarm relays. Any or all of the following functions can be selected for each
relay.
The description of how the trip levels and the delay times are set is in the 1732 Technical Manual.
NOTE: The process alarms will only be activated if they are enabled in SETUP menu function 06.
20. 'Oxygen 1 Very Low'
21. 'Oxygen 2 Very Low'
The measured oxygen level on the indicated probe has been below the trip level shown in setup function #07
for longer than the delay time shown in setup function #08.
22. 'Oxygen 1 Low'
23. 'Oxygen 2 Low'
The measured oxygen level on the indicated probe has been below the trip level shown in setup function #09
for longer than the delay time shown in setup function #10.
24. 'Oxygen 1 High'
25. 'Oxygen 2 High'
The measured oxygen level on the indicated probe has been above the trip level shown in setup function
#11 for longer than the delay time shown in setup function #12.
26. 'Oxygen Deviation'
The difference between the oxygen level measured on probe #1 and the oxygen level measured on probe #2
is greater than the trip level shown in setup function #13 and the time delay shown in setup function #14 has
expired.

27. 'Probe 1 Temperature Low'
28. 'Probe 2 Temperature Low'
The probe temperature is under 650°C/1200°F. The oxygen reading is therefore invalid. If the probe heater
has been on for more than 20 minutes and the temperature is less than 650°C/1200°F a 'Probe 1(2) Heater
Fail' alarm will occur. There will be a flashing 'T' symbol on the bottom left hand corner of the display until
the temperature of the probe(s) is over 650°C/1200°F.
NOTE: The 'Probe 1(2) Temperature Low' function is also used with unheated probes to show that the probe
temperature is below 650°C/1200°F when the process temperature falls below this level.
29. 'Cal 1 in Progress'
30. 'Cal 2 in Progress'
A calibration check is occurring, either manual or automatic mode.
31. 'Purge 1 in Progress'
32. 'Purge 2 in Progress'
A probe purge is occurring, either manual or automatic mode.
