Status Bar Icons (Cont.)
FTP Primary Server Failure This error occurs if the recorder fails to establish connection
with the primary server, after two attempts. After the second
attempt fails, the recorder attempts to establish connection
with the secondary server instead. Primary and secondary
server details are entered in the Network. Archiving area of
configuration (Section 5.1.2).
FTP Secondary Server Failure This error occurs if the recorder fails to establish connection
with the secondary server, after two attempts. Primary and
secondary server details are entered in the Network.Archiving
area of configuration (Section 5.1.2).
Maths channel failure Appears if, for example, the divisor of a divide function is zero.
Media archiving file lost A file has been deleted that had not yet been archived. Possible
causes: Memory stick missing, full or write protected; archiving
has been disabled; archiving rate too slow.
Media archiving to slow The archive rate is too slow to prevent the internal memory
from overflowing. The recorder effectively switches to
‘Automatic’ (Section 5.1.2) to ensure that data is not lost.
Media full Archive storage device is full. The alarm becomes active only
when an archive is in progress.
Media missing No archive storage device present when archive attempted.
Non-volatile memory failure RAM copy of non-volatile parameters is corrupted.
Non-volatile Write Frequency warning
One or more parameters are being written frequently to non-
volatile memory. If this continues, it may lead to ‘memory
depletion’ (i.e. the memory will no longer be able to store
values correctly). A common cause of this problem is frequent
writes over Modbus comms.
Recording failure (message) Message explains reason for failure.
USB overcurrent USB power fault - too much current (i.e. >100mA) is being
drawn by a USB device.
Wiring failure The user wiring has failed to verify, i.e. one or more wires has
been detected that does not have both a source and a
destination defined. This may be the result, for example, of
power loss during a download from iTools.
CHANNEL ALARM
This indicator appears if any channel (including channels not in the display group) is in an alarm state. The
symbol is illuminated continuously if all alarms are acknowledged or flashes if any one or more alarms is
unacknowledged. Alarms are acknowledged from the Root menu ‘Alarm summary’ item as described in
Error! Reference source not found. or in the Channel configuration area if the user’s access permission is
appropriate.
USB
This icon appears whenever a memory stick (max. capacity 8GB) or other supported USB device (section
8) is plugged into the USB port at the rear of the recorder.
When data transfer is in progress between the instrument and the memory stick, the icon changes to a
‘busy’ version.
CAUTION
The Memory stick must not be removed while archiving (demand or automatic)
is in progress, as to do so may irreparably damage the file system of the
memory stick, rendering it unusable. It is recommended that all archiving be
suspended before the memory stick is removed.
