The function registers its operation into the last twelve (12) time-stamped registers; this information is
available for all provided instances separately. The register of the function records the ON event
process data for START, TRIP or BLOCKED. The table below presents the structure of the function's
register content.

5.3.12 Non-directional undercurrent protection (I<; 37)
The non-directional undercurrent function is used for instant and time-delayed undercurrent protection.
The operating decisions are based on phase current magnitude, constantly measured by the
function. The available phase current magnitudes are equal to RMS values. The blocking signal and the
setting group selection control the operating characteristics of the function during normal operation,
i.e. the user or user-defined logic can change function parameters while the function is running.
The outputs of the function are the START, TRIP and BLOCKED signals. The undercurrent function
uses a total of eight (8) separate setting groups which can be selected from one common source.
The function can operate on instant or time-delayed mode. In the time-delayed mode the operation can
be set to operate on definite time (DT) delay.
The inputs for the function are the following:
• setting parameters
• digital inputs and logic signals
• measured and pre-processed current magnitudes.
The function outputs the START, TRIP and BLOCKED signals which can be used for direct I/O
controlling and user logic programming. The function generates general time-stamped ON/OFF events
to the common event buffer from each of the three (3) output signals. In the instant operating mode the
function outputs START and TRIP events simultaneously with an equivalent time stamp. The time stamp
resolution is 1 ms. The function also provides a resettable cumulative counter for the START, TRIP and
BLOCKED events.
