6.1.2 Error Log and Operational Log
The Model 2000 maintains two history logs. The logs may be accessed while in Stop mode, once
Diagnostic Mode is activated, by pressing the Down Arrow key. The Error Log screens are labeled
UD2 and the Operational Log screens are labeled UD3. The Operational Log contains a history of
the last 16 alerts and recoverable alarms. The Error Log contains a history of the last 8 non-
recoverable alarms. Note that power failures do not generate a logged alarm. Each screen provides
information on the state of the Control Module when the event occurred including the current system
hours.
