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.

alarm

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).
