10 MAINTENANCE
The EGA4 analyzer has been developed and manufactured using high quality components. A correct, systematic
maintenance will prevent damage and will increase substantially the life of the instrument, giving excellent results.
Anomalous conditions that require extraordinary maintenance interventions are promptly displayed, either clearly or with
an information code.
10.1 Error messages
The instrument performs the autodiagnostic procedure when switched on. When measuring it checks also for
anomalous conditions. If analyzer founds trouble, it display a message on LCD. Sometime these messages corresponds
to a unrecoverable problem and it is necessary to return the instrument to Eclipse for maintenance. Frequently these
message are referred to a recoverable trouble and can be solved by yourself.
The following table show the possible instrument error messages:
Error message Problem Solutions
Calc Err Parameter calculus error. The instrument cannot perform the
calculus. Check and solve the others error
conditions.
Probe Er The external Rtd probe is
unconnected or damaged. Connect or replace the external
temperature probe.
RJ Err Internal temperature reference
damaged. Return the instrument to Eclipse for
maintenance
Over Overrange condition The problem is solved automatically when
measure return inside the range
Under Underrange condition The problem is solved automatically when
measure return inside the range
-------- No calculus available The instrument cannot perform the
calculus. Check and solve the others error
conditions. (e.g. O
2
>18%).
Excluded
CO sensor excluded by electro-valve Automatic CO sensor protection is active.
Perform one or more autozero cycle in
fresh air.
Tc Error The thermocouple is unconnected or
damaged. Connect or replace the temperature probe.
Tsens Er Cell compensation error Return the instrument to Eclipse for
maintenance.
Zero Err
The autozero procedure is failed Perform one or more autozero cycle in
fresh air. If the problem remain, Return the
instrument to Eclipse for maintenance.
Sens. Er Broken cell Return the instrument to Eclipse for
maintenance.
No meas. Empty Memory
No sens. The cell is non installed
No probe No external probe connected on
mini-din connector. Connect or replace the temperature probe.
10.2 Set-up menu
Configuration menu is protected by a password. This procedure menu allows the operator to change some internal
parameters values: Date and time internal clock, communication baud rate, autozero time and leak test timing.
