[G31: Alarm setting] Selection of the alarm output

during a setting error occurrence

This parameter specifies whether the alarm will

be recognized as an alarm during a setting error

occurrence.

Setting

Function

No

Not recognized as an alarm

Yes

Recognized as an alarm

[G35: Alm Display] Selection of the alarm display

form.

This parameter specifies the alarm display form of

the display unit and configuration tools.

Setting

Function

Normal

The alarm display form does not follow

NE-107.

NE107

The alarm display form follows NE-107.

NOTE

The AXR has three different type of alarm (i.e.,

system alarms, process alarms, and setting

alarms). For setting alarms and process alarms,

settings are made with

G26, G27, G28, G29 and

G31 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.

[G40: Operation Time] Display of operation time

This parameter is used to display the operation

time. The operation time is the total time that is

counted while the device works actually.

When the power supply is off, the operation time is

not counted.

For example, “1D23:45” indicates an operation time

of 1 day, 23 hours, and 45 minutes.

IMPORTANT

Use this value as a rough guideline because the

operation time has an error.

[G41: Alm Record1] Alarm record1

This parameter is used to display the most-recent

alarm, and the alarms that can be displayed are as

follows.

display unit.

NOTE

Records for “30: Sig Overflow” are kept only

when

G26 specifies that this condition is to be

recognized as an alarm (i.e., “Yes” is selected).

Records for “31: Empty Pipe” are kept only

when

G27 specifies that this condition is to be

recognized as an alarm (i.e., “Yes” is selected).

Records for “33: Adhesion Alm” are kept only

when

G29 specifies that this condition is to be

recognized as an alarm (i.e., “Yes” is selected).
