Figure 80 - Gas % Leak Rate Thresholds; Figure 81 - Gas % Leak Rate Alarms; Figure 82 - Gas Graph Selection - GE CSE Uniserve CB Watch 3 Operating Manual

Alarms can be set on the long-term gas % leak rate (the most used metric because
government and corporate targets are set in terms of % SF
Two thresholds are required to be entered by the user during setup:
• Warning threshold H, same for all poles
• Alarm threshold HH, same for all poles
HMI: Settings/Gas monitoring
The % leak rate alarms are displayed with the other gas alarms
HMI: Measurements/Alarms
Historical Graphs
On the HMI, you can view graphs displaying the history of the key gas parameters. Using the
drop-down menu, you can select either:
• Short term graphs: with resolution of 1 value every 10 minutes
• Long term graphs: with resolution of 1 value per day
HMI: Measurements/Gas
The "short term" selection displays the history of:
• Gas density
• Gas pressure at 20
• Gas temperature
