8. ACTUAL OPERATON
8.2 Self-diagnostics Functions
The self-diagnostics function displays instrument internal errors, input/output signal
abnormalities, setting errors, and other problems.
When an alarm occurs, the alarm number that the error has occurred and normal data
are alternately indicated on the indicator of ADMAG SE.
However, alarms are only displayed during flow rate data display mode and when
parameter numbers are being changed in the setting mode. (Alarms are not displayed
when data items are being changed.)
The current output during the alarm occurrence can be selected from among the
followings. See “8.2.1 Output Status during Alarm Occurence.”
2.4mA or less
4mA
HOLD
21.6mA or more
When the BT200 is used, alarms are displayed in “A60 to N60:SELF CHECK
parameter.
When the HART Communicator is used, alarms are displayed in “Status group 1 to
3” parameters. There are two methods for self-diagnostics, every transmission and
manually executing the “Self test” command. See “8.2.2 Self-diagnostics Using
HART Communicator.”
When an error message appears, follow “8.2.3 Error Description and Countermea-
sure.”.
