Event Recording
The overcurrent control features an internal event recorder that captures the last
12 fault operations for each fault interrupter. The event log indicates which poles
have experienced a fault, the magnitude of the fault, and whether a ground over
current was involved. This information can be accessed via a personal computer
con nected to the data port of the control.
Self Testing
Whenever the overcurrent control is powered up—and then periodically
thereafter—it automatically goes through a selftest procedure to test vital sub
systems and ensure proper operation. The control checks the trip capacitors,
powersupply voltage, RAM, EEPROM, integrity of the data, and voltage control. It
then flags whatever fails the selftest.
