5-60 | Model 900 ADA / Model 930 Sulfur Pit Analyzers
If two or more alarms are detected simultaneously, the displayed alarm
status code is a sum of the primary alarm codes. To resolve a non-primary
status code into its primary alarm codes, subtract the largest primary
alarm code from the displayed number. Continue to subtract the largest
primary code from the remainder until a primary alarm code is left.
Example:
The displayed Host Controller board status code is 20. The alarms detect-
ed are:
20
- 16 f Temp low (Fault – Host Controller)
4 f Internal communication (Fault – Host Controller)
