7.5.1.1.3 Trip Point
This is the value for selected parameter
limit which is used as a reference for
relay tripping. It is represented as
percentage value.
Percentage value is calculated
on nominal value.
Different ranges for different
parameters are shown in table - 8.
Pressing key increments digit value & pressing key
decrements digit value. Press Enter key to confirm newly
changed trip point. The above screens shows the toggle
between its parameter name and its value for 3 sec.
7.5.1.1.4 Hysteresis
Hyteresis is the value below
high alarm trip point or above
low alarm trip point, which
when crossed by the
measured parameter, resets the relay to its position before
tripping. The value of hysteresis can range from 0.5 to 50% and
it gets calculated on trip point value.
e.g. The above screen shows the hysteresis value of 50%
7.5.1.1.5 Energizing Delay
Energizing delay is the time
in seconds taken by the relay
before tripping after an alarm
condition has occurred.
The value for this parameter can range from 0001 to 9999.
7.5.1.1.6 De-energizing Delay
De-energizing delay is the
time in seconds taken by the
relay before coming out of
the trip state, after a normal
condition has observed. The value for this parameter can range
from 0001 to 9999.
7.5.1.2 Pulse Relay Configuration
Pulse relay can be used with a mechanical counter to measure
energy. It is a potential free, very fast acting relay contact.

This parameter decides on which measurement
parameter, the pulses will be occurring. The options
for this setting are 0 & 1
as explained in Table-7.
Table-7
7.5.1.2.2 Pulse Divisor
This parameter decides after how many units of energy
a pulse should appear at output. Refer Table-9 for Pulse
Divisor options. Below screens shows the toggle between
its parameter name and its value for every 3 sec.
7.5.1.2.3 Pulse Duration
This parameter decides the width of the output pulse.
The options for this parameter are 60, 100 and 200 ms as
shown below. Below screens shows the toggle between
its parameter name and its value for every 3 sec.
7.5.1.3 Timer
This menu contains the parameters for timer output
configuration.
7.5.1.3.1 Number of Cycles
This value decides how many times the timer will repeat
the switching after once started. If this value is set as 0,
timer will keep repeating the cycles until stopped.
