Undervoltage pickup establishes the voltage level below which the
function timer will start.
Enables or disables the undervoltage inhibit feature.
Undervoltage inhibit establishes the voltage level below which the
function will be disabled.

NOTE:
Two or four voltage inputs are available
for the M-3311A. The Voltage Input can
be a phase voltage input or voltage
generated from a broken delta VT con

nection. 81O/U, 27, and 24 Functions
are only available if the voltage input is
connected to the phase voltage. If the
voltage input is connected to phase volt-
age, Function 59G will be unavailable.
Function 59G is only available if the
voltage input is connected to a broken
delta VT.
The 27 Undervoltage function may be used to detect
any condition causing long term undervoltage
This function is used to shed the transformer load
when the power system does not have enough re

active support, similar to the Over/Underfrequency
(81O/U) function.
The Inhibit setting of this function prevents it from
operating during fault conditions.
