activated and configured for each input in the Protection parameters - Other parameters A (and B if dual

Each alarm threshold has the following configuration parameters:
NOTE: the table lists the parameters of threshold A of input I42; the names and references
of all the other thresholds and inputs change
Parameter Description
Threshold A enable Activates verification of input I42 with alarm Threshold A
Defines whether the alarm must activate when measurement
Threshold A hysteresis
is above ( Up ) or below ( Down ) the set value, with reference to
direction
the Threshold A setting
Alarm threshold A of input I42. The value is given in degrees
Celsius (°C) and can be set within the range: -40°C to 240°C,
in 0.1°C steps.
Threshold A value
Hysteresis value, valid for quitting the alarm condition if the
set Treshold A alarm threshold has been exceeded.
The hysteresis parameter only allows positive values. The trip
unit decides whether to add or subtract this value to or from
the alarm threshold on the basis of the direction parameter,
example:
• Direction = Up, Value = 200°C, hysteresis = 10°C, the alarm
Threshold A hysteresis
activates over 200° and de-activates below 190°C
The value is expressed in degrees Celsius (°C) and can be set
within the range: 0°C to 50°C with 0.1°C steps.
NOTE: the thresholds of the 4-20 mA (I41 and I51)
Current Loop input are given in percentage form and
can be set within the range: 0% to 100 %, in 0.1% steps
(each step equivalent to 0.016 µA)
NOTE: the thresholds associated with the 4-20 mA (I41
and I51) Current Loop input are given in percentage
form and can be set within the range 0% to 30 %, in
0.1% steps (each step equivalent to 0.016 µA)
