[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:
This parameter specifies whether the setting alarm will be recognized as an alarm.
Setting | Function |
|
|
No | Not recognized as an alarm |
|
|
Yes | Recognized as an alarm |
|
|
T0633.EPS
[G31:
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.

T0635.EPS
[G33:
(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 | Not recognized as an alarm |
|
|
Yes | Recognized as an alarm |
|
|
T0636.EPS
NOTE
To set “HH/LL Alarm” as an alarm, it is necessary to set “HH/LL Alarm” according toF10: SO1 Function
or F11: SO2 Function, and set G12: Low Low
Alarm or G13: High High Alarm as well.
[G34:
This parameter specifies whether the electrode adhe- sion alarm in process alarms will be recognized as an alarm.
Setting | Function |
|
|
No | Not recognized as an alarm |
|
|
Yes | 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.
