Status messages
The EK280 gives two types of status information: Momentary status "
Stat
" (also referred to as "status") and
status register "
SReg
". These are located on the "
Admin.
" and "
Serv.
" display tabs under "
Status
".
Messages in the "
Stat
" momentary status indicate current conditions such as pending errors. As soon as the
condition is no longer present, the relevant message is removed from the momentary status.
Alarms, warnings and remarks are displayed in the momentary statuses (i.e. messages with numbers in the
range of "1" to "16")
All messages since the last manual clear are collected in status register "
SReg
". Here you can see, which
messages have been generated since the last station inspection or data retrieval. Status register messages
can be cleared by the user.
Only alarms and warnings are displayed in the status register (i.e. messages with numbers in the range "1" to
"8"). Remarks are not stored as they communicate events which do not cause disruption or are not persistently
relevant (i.e. "summertime", "calibration lock open" or "data transfer in progress").
S.Reg
and
Stat
are summaries of multiple status values.
They
initially display all available messages as
numbers.
Pressing <ENTER> allows you to see these individually as short texts: The most important message (with the
lowest number) is displayed first. Using the
and
keys you can move to the next or preceding message.
The display shows the name of the relevant status word and the message number with preceding "#" in front
of the short text. This information can be useful for entering a "status point" for the outputs.
10.1

SReg
(not
Stat
) can be cleared using the

List of status messages
Message
Description, process
a) Faults, alarms:
Restart
If this message appears whilst in operation, the device is faulty.
Please contact Elster support.
C-fact. err.
The conversion factor could not be calculated as the measured gas temperature
was outside -100°C to +100°C or no usable compressibility ratio factor was
available.
Data error
An error was detected during the cyclic check of the data subject to calibration
regulations.
Please contact Elster support.
T Alarm Lim.
The gas temperature measured is outside acceptable limits.
The limit values can be changed when putting the device into operation in the
presence of a calibration officer (see Operating Instructions [1]).
p Alarm Lim.
The measured gas temperature is outside the permissible limits.
The limit values can be changed when putting the device into operation in the
presence of a calibration officer (see Operating Instructions [1]).
K-val. error
The compressibility ratio factor could not be calculated as no valid real gas factor
could be determined.
