Item to be selected Brief description
High-high- If "high-high alarm ON" is selected, contact output occurs when the high-high-limit
limit alarm alarm is issued. To do this, it is required, in alarm setup, that the
high-high alarm be set on beforehand (see Section 8.3).
High-limit If "high alarm ON" is selected, contact output occurs when the high-limit alarm
alarm is issued. To do this, it is required, in alarm setup, that the
high-limit alarm be set on beforehand (see Section 8.3).
Low-limit If "low alarm ON" is selected, contact output occurs when the low-limit alarm is
alarm provided. To do this, it is required, in alarm setup, that the
low-limit alarm be set on beforehand (see Section 8.3).
Low-low-limit If "low-low alarm ON" is selected, contact is on when the low-low-limit alarm is
alarm issued. To do this, it is required, in alarm setup, that the low-low
Calibration coefficient alarm If calibration coefficient alarm is ON (enabled), then when a zero- calibration
coefficient alarm (alarm 6) or span calibration coefficient alarm (alarm 7) occurs then
calibration coefficient alarm contact output occurs (see Sec. 12.2.1 Alarms)
Startup power stabilization If set ON then contact output occurs when startup power stabilization timeout alarm
timeout alarm (alarm 8) occurs (see Sec.12.2.1 Alarms)
alarm be set on beforehand (see Section 8.3).
Error If "Error ON" is selected, contact output occurs when an error results.
(See Chapter 12, "Troubleshooting.")
Warm-up If "Warm-up ON" is selected, contact output occurs during warm-up.
For the definition of warm-up, see Section 8.2.1.
Output range If "Range Change ON" is selected, contact output occurs ("answer-back signal
change to a range change signal") while a range change signal is
applied to a contact input. To do this, it is required, in input contact setup,
that the range change be selected beforehand. For more on this, see Section 8.5.
Calibration If "Calibration ON" is selected, contact output occurs during calibration.
For the definition of "During calibration," consult Section 8.2.1.
Maintenance If "Maintenance ON" is selected, contact output occurs during maintenance.
For the definition of "During maintenance," consult Section 8.2.1.
Blow back If "Blow back ON" is selected, contact output occurs during blow back.
For the definition of "During blow back," consult Section 8.2.1.
High-limit Not supported by the oxygen analyzer.

Calibration- If "Cal. gas press. low ON" is selected, contact output occurs ("answer-back
gas press. low signal to a calibration-gas low-pressure signal")when a calibration-gas low-
pressure signal is applied to the contact input. To do this, it is required, in input
contact setup, that "Cal. gas press. Low" be selected beforehand. For more on this,
see Section 8.5.
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.
To do this, it is required, in input contact setup, that "process upset" be selected
beforehand (see Section 8.5).
