Table 1.2.1 Alarm icons
4.2.2 Status Bar Icons
The following items can appear in a dedicated window immediately to the left of the time and date, at the
bottom right-hand corner of the display. The width of this window expands as the number of icons
increases, and the instrument name is truncated, as necessary, to make room.
SYSTEM ALARMS
This indicator appears, flashing, if any one or more of the alarms listed below is active. The System
Alarms summary page (accessed from ‘Go to View in the top level menu) allows the user to view such
system alarms as are active. It is not possible to ‘acknowledge’ system alarms
Archive Disabled An unattended archiving strategy has temporarily been
disabled.
Archiving Failed An unattended archiving strategy has failed to complete.
Archiving Timeout A configured archiving strategy has timed out.
Battery failure Indicates that the battery is approaching the end of its useful
life, or that it is missing or is completely exhausted. Immediate
battery replacement is recommended (Appendix C;
section C1 ).
Broadcast Storm detected Networking is limited until the storm has passed.
Clock failure The internal clock was found to be corrupt at power up, or that
the time has never been set. Time is forced to 00:00 1/1/1900.
Can be caused by battery failure, in which case a battery failure
message appears. The error is cleared by setting the time and
date.
Channel error Indicates a hardware failure in the channel circuit or in the
internal cold junction temperature measurement.
Database failure Corrupted EEPROM or flash memory.
DHCP Server failure For units with ‘IP Type’ set to ‘DHCP’ (Network.Interface
configuration) this alarm occurs if the instrument is unable to
obtain an IP address from the server.
FTP Archiving file lost A file has been deleted that had not yet been archived. Possible
causes: Communications with the server could not be
established,; archive is disabled; archive rate too slow.
FTP 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.
