When using contact output as an answer-back signal for an input contact, be sure to make an input contact setting.
<8. Detailed Data Setting>
Brief description
If "High-High alarm ON" is selected, contact output occurs when the
high-high limit is issued. To do this, it is required, in Alarms setup, that
the high-high alarm be set on beforehand (see Section 8.3).
If "High alarm ON" is selected, contact output occurs when the high
limit alarm is provided. To do this, it is required, in Alarms setup, that
the high limit alarm be set on beforehand (see Section 8.3).
If "Low alarm ON" is selected, contact output occurs when the low
limit alarm is provided. To do this, it is required, in Alarms setup, that
the low limit alarm be set on beforehand (see Section 8.3).
If "Low-Low alarm ON" is selected, contact output occurs when the
low-low limit alarm is issued. To do this, it is required, in Alarms setup,
that the low-low alarm be set on beforehand (see Section 8.3).
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)
If set ON then contact output occurs when startup power stabilization
timeout alarm (Alarm 8) occurs (see Sec.12.2.1)
If "Error ON" is selected, contact output occurs when an error is
issued. (See Chapter 12, Troubleshooting).
If "Warm-up ON" is selected, contact output occurs during warm-up.
For the definition of Warm-up (see Section 8.2.1).
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. To do this, it is required, in Input contacts
setup, that the range change be selected beforehand. For more on
this (see Section 8.5).
If "Calibration ON" is selected, contact output occurs during
calibration. For the definition of Under calibration (see Section 8.2.1).
If "Maintenance ON" is selected, contact output occurs during
maintenance. For the definition of Under maintenance (see Section
8.2.1).
If "Blow back ON" is selected, contact output occurs during blow
back. For the definition of During blow back (see Section 8.2.1).
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.
To do this, it is required, in Input contacts setup, that "Cal. gas press.
low" be selected beforehand. For more on this (see Section 8.5).
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 contacts
setup, that "Process upset" be selected beforehand (see Section 8.5).
