Setting Function
[G22: 4-20mA Burn Out] Display of the current
output during a CPU failure
This parameter displays the current output direction for
a CPU failure (i.e., burnout). Note that communication
will not be possible if such a failure occurs.
With the standard specification, this is set to High and
25mA is output when a failure occurs. Low is setup for
optional code C1, and in such a case, 0mA is output
when a failure occurs.
NOTE
The current output direction for a CPU failure
(i.e., burnout) can be changed. Refer to selec-
tion 10.2.1: Setting of Burnout Switch.
[G30: Alm-Setting] Alarm recognition of “Setting
Alarm”
This parameter specifies whether the setting alarm will
be recognized as an alarm.

No
Yes
[G31: Alm-Sig Over] Alarm recognition of “Signal
Overflow Alarm”
This parameter specifies whether the signal overflow in
process alarms will be recognized as an alarm. A signal
overflow occur when there is an error in the input
signal.
T0634.EPS
Setting Function
No
Yes
Not recognized as an alarm
Recognized as an alarm
[G32: Alm-Emp Pipe] Alarm recognition of “Empty
Pipe Alarm”
This parameter specifies whether the empty pipe
(flowtube is not filled with fluid) in process alarms will
be recognized as an alarm.
Setting Function
No
Yes
T0635.EPS
Not recognized as an alarm
Recognized as an alarm
[G33: Alm-HH/LL] Alarm recognition of “HH/LL
Alarm”
(Refer to the descriptions of G12 and G13 for more
details regarding HH and LL alarms.)
This parameter specifies whether HH/LL alarm in
process alarms will be recognized as an alarm.
Setting Function
No
Yes
T0636.EPS
Not recognized as an alarm
Recognized as an alarm
NOTE
To set “HH/LL Alarm” as an alarm, it is necessary to
set “HH/LL Alarm” according to F10: SO1 Function
or F11: SO2 Function, and set G12: Low Low
Alarm or G13: High High Alarm as well.
[G34: Alm-Adhesion] Alarm recognition of “Adhe-
sion Alarm”
This parameter specifies whether the electrode adhe-
sion alarm in process alarms will be recognized as an
alarm.
Setting Function
No
Yes
T0636-1.EPS
Not recognized as an alarm
Recognized as an alarm
NOTE
The AXFA11 has three different types of alarm
(i.e., system alarms, process alarms and setting
alarms). For setting alarms and process alarms,
settings are made with G30, G31, G32, G33 and
G34 to specify whether these will be recognized
as an alarm.
Refer to Section 6.5: Alarm Functions for more
details regarding the content of each alarm and
the effect of alarm recognition on output.
