HOW THE CIRCUIT MONITOR CAPTURES AN EVENT

When the circuit monitor senses the trigger—that is, when the digital input transitions from OFF to ON, or an alarm condition is met—the circuit monitor transfers the cycle data from its data buffer into the memory allocated for event captures. The number of cycles or seconds it saves depends on the number of cycles or seconds you selected.

Figure 8–1shows an event capture. In this example, the circuit monitor was monitoring a constant load when a utility fault occurred, followed by a return to normal.
