3.1.3 ALARM INDICATORS (Cont.)
INSTRUMENT ALARMS
This indicator appears, flashing, if any of the following alarms are active. The Instrument alarm summary page, de-
scribed above, allows the user to view any such alarms.
Archive failed -(message)
Message explains archive failure - due to disk being missing, write protected,
faulty, full etc.
Battery-backed RAM cleared
This message appears if the battery has failed, and the unit has been switched off.
Channel failure
Indicates a hardware failure in the input channel circuit
Channel error
Indicates a hardware failure in the channel circuit or in the internal CJ temperature
measurement
Clock failure
Internal clock was corrupt at power up, or the time has never been set. Can be
caused by battery failure, in which case the battery icon will also be visible. The
error is cleared by setting the time and date. Server time forced to 00:00 1/1/1900.
Floppy disk worn
Appears if a number of attempts had to be made before write to the disk was suc-
cessful. No data is lost, but the disk should be replaced as soon as is practicable.
Floppy disk corrupt
This appears if all attempts to write to the disk fail. In such a case, some data may
be lost. If the damaged area of the disk is in the system part of the disk, it might
appear to the recorder that it is unformatted, and the disk icon will disappear. The
disk should be replaced immediately.
FTP Primary Server Failure
This error is set if the recorder fails, after two attempts, to establish communica-
tions with the primary server as defined in Archive Configuration (
After the second attempt has failed, the Secondary server is tried.
FTP Secondary Server Failure
This error is set if the recorder fails, after two attempts, to establish communica-
tions with the secondary server as defined in Archive Configuration (
See also 'FTP Primary Server Failure, above.
Insufficient non-volatile memory...
There is insufficient memory available for the configuration. Sometimes caused by
the use of the Rolling Average maths function.
Internal flash: \user\ required repair
Error found (in the internal file system) at power-up, and corrected.
Internal flash: \system\ required repair
Error found (in the internal file system) at power-up, and corrected.
Internal flash: \history\ required repair
Error found (in the internal file system) at power-up, and corrected.
Maths Channel failure
Appears, for example, if the divisor of a divide function passes through zero.
Network boot failure
The recorder is unable to establish connection with the bootP server. This might be
caused by, for example, cable failure, network hardware failure, etc.
Recording failure - (message)
Message explains recording failure e.g. file error, internal overflow etc.
Removable media failure
This error is set if the disk is corrupt, wrongly formatted etc. Becomes active only
when an Archive is attempted.
Removable media full
Floppy disk or PC card full. Becomes active only when an Archive is in progress.
SNTP server failure
This alarm is set if:-
a) the year received from the server is < 2001 or > 2035 or
b) the configured SNTP server cannot be accessed
Time synchronisation failure
Set if 5 or more 'Time change events' are caused by the SNTP server within 24 hrs.
A 'Time change event' is defined as occuring whenever the recorder time is found
to be more than 2 seconds different from the server time. The alarm does not ap-
pear until 24 hours after the first of the five-or-more Time Change events occurred.
