ENABLE U/V TRIP & ALARMENABLE U/V TRIP & ALARM
IF AVG. VOLTS=0? XXXIF AVG. VOLTS=0? XXX
This setpoint should be used if an undervoltage alarm or trip is desired on a dead bus, i.e. when the av-
erage voltage of all three phases is zero.
YES - Enables undervoltage trip & alarm features if the average voltage received from the meter is zero.
Reset of an U/V trip or alarm is only possible if the average voltage goes above the setpoints.
NO - If the bus is de-energized (or dead), the 269 will not issue an undervoltage trip or alarm. In fact, if
an undervoltage trip or alarm condition existed prior to the average voltage becoming zero, these
conditions may be reset after the average voltage becomes zero.

UNDERVOLTAGE ALARM LEVELUNDERVOLTAGE ALARM LEVEL
U/V ALARM = XX %VTU/V ALARM = XX %VT
This setpoint sets the threshold for the undervoltage alarm condition as a percentage of VT primary.
The alarm level programmed in this setpoint is compared to the average voltage received from the me-
ter.
NOTE: To detect an undervoltage alarm upon complete loss of all three phases, the setpoint "Enable U/V
Trip & Alarm if Avg. Volts=0?" must be set to Yes.
30-95 % (increments of 1) or OFF
Factory Value = OFF

This setpoint sets the time that an undervoltage alarm condition must persist in order to facilitate an
alarm.
