Alarm and
Error
settings
High-high-limit alarm
If “high-high alarm ON” is selected, contact output occurs during a high-high-
limit condition. In alarm setup the high-high alarm must be set ON (see
Section 1.47).
High-limit alarm
If “high alarm ON” is selected, contact output occurs during a high-limit alarm
condition. In alarm setup the high-limit alarm must be set ON (see Section
1.47).
Low-limit alarm
If “low alarm ON” is selected, contact output occurs during a low-limit alarm
condition. In alarm setup the low-limit alarm must be set ON (see Section
1.47).
Low-low-limit alarm
If “low-low alarm ON” is selected, contact output occurs during a low-low-limit
alarm condition. In alarm setup the low-low alarm must be set ON (see
Section 1.47).
Calibration coefficient
alarm
If calibration coefficient alarm is ON (enabled) when a zero-calibration
coefficient alarm (alarm 6) or span calibration coefficient alarm (alarm 7)
condition occurs, calibration coefficient alarm contact output occurs (see
Section 1.62.1 Alarms).
Startup power
stabilization timeout
alarm
If set ON then contact output occurs when startup power stabilization timeout
alarm (alarm 8) occurs (see Section 1.63.1 Alarms).
Error
If “Error ON” is selected, contact output occurs when an error results.
(See Chapter 0, “Troubleshooting.”)
Other
settings
Warm-up
If “Warm-up ON” is selected, contact output occurs during warm-up.
For the definition of warm-up, see Section 1.46.1.
Output range change
If “Range Change ON” is selected, contact output occurs (“answer-back signal
to a range change signal”) while a range change signal is applied to a contact
input. In input contact setup the range change must be selected. For more on
this, see Section 1.49.
Calibration
If “Calibration ON” is selected, contact output occurs during calibration. For
the definition of “During calibration,” consult Section 1.46.1.
Maintenance
If “Maintenance ON” is selected, contact output occurs during maintenance.
For the definition of “During Maintenance,” consult Section 1.46.1.
Blow back
If “Blow back ON” is selected, contact output occurs during blow back. For the
definition of “During blow back,” consult Section 1.46.1.
High-limit temperature
alarm
Not supported by the oxygen analyzer.
Calibration-gas press.
low
If “Cal gas press. low ON” is selected, contact output occurs (“answer-back
signal to a calibration-gas low-pressure signal”) when a calibration-gas low-
pressure signal is applied to the contact input. In input contact setup “Cal. gas
press. low” must be selected. For more on this, see Section 1.49.
Process upset
If “Process upset” is selected, contact output occurs (“answer-back signal to a
process upset signal”) when the process upset signal is applied to the contact
input. In input contact setup “process upset” must be selected (see Section
1.49.)
Note: To provide an alarm with an output contact, make an alarm setting.
When using contact output as an answer-back signal for an input contact, make an input contact.
