Advanced Trip Diagnosis
The Phoenix scanner provides trip diagnosis for several advanced parameters including: Power Spec-
trum Density, Average Amplitude, Best Fit, Single Source, Internal Fault, or a combination of these.
Whenever the scanner trips in response to a flame out condition, the reason for the trip is stored in a Trip
Register. A total of eight (8) trip events are stored in the Trip Register with the oldest stored in the bottom
position LED (1) and the newest in the top position LED (8).
NOTE: Once filled, the Trip Register MUST be reset in order to store subsequent trips. It will
NOT automatically reset or roll-over.

Step 2 - Selecting the Trip Event in the Trip Register

LEDs. To select a specific trip event in the Trip Register, use the
