Error message type
Users have the option of weighting certain errors differently, in other words having them
classed as “
Fault messages” or “Notice messages” . You can define messages in this
way with the aid of the function matrix see the “Description of Device Functions”
manual).
Serious system errors, e.g. module defects, are always identified and classed as “fault
messages” by the measuring device.
Notice message (!)
Displayed as Exclamation mark (!), error type (S: system error, P: process error).
The error in question has no effect on the outputs of the measuring device.
Fault message (
$
)
Displayed as Lightning flash (
$
) , error type (S: system error, P: process error).
The error in question has a direct effect on the outputs.
The response of the outputs (failsafe mode) can be defined by means of functions in
the function matrix (see Page 69).
!
Note:
Error messages can be output via the pulse/frequency output.
If there is an error message present a higher signal on alarm level can be output via
the current output in accordance with NAMUR Recommendation NE 43.
Confirming error messages
For the sake of plant and process safety, the measuring device can be configured in
such a way that fault messages (
$
) always have to be rectified and acknowledged
locally by pressing
F
. Only then do the error messages disappear from the display.
This option can be switched on or off by means of the “ACKNOWLEDGE FAULT
MESSAGES” function (see the “Description of Device Functions” manual).
!
Note:
Notice messages (!) do not require acknowledgment. Note, however, that they remain
visible until the cause of the error has been rectified.
