Arcteq Generator Commander, Instruction Manual

Page: 140 / 561

In the release delay option the operating time counter calculates the operating time during the release.
When using this option the function does not trip if the input signal is not re-activated while the release
time count is on-going.
Events and registers
The undervoltage function (abbreviated "UV" in event block names) generates events and registers
from the status changes in START, TRIP, and BLOCKED. The user can select which event messages
are stored in the main event buffer: ON, OFF, or both. The function offers four (4) independent stages;
the events are segregated for each stage operation.
The events triggered by the function are recorded with a time stamp and with process data values.
