Tab. 7.1. Possible combinations of the bargraph colours
“Pr1P”
÷
“Pr4P”
- these parameters allows to define which one of the thresholds of the
relay will be showed on bargraph.
“oFF”
- no one thresholds will be marked,
“1St”
- threshold refer to
„SEtP”
, will be marked only
“2nd”
- threshold refer to
„SEt2”
, will be marked only
“botH”
- both thresholds will be marked.
“P1AL”
÷
“P4AL”
- these parameters allows to define
the critical situation of the
bargraph
depend on state of particular relays.
“noC”
- particular relay do not causes by critical situation on the bargraph.
“morE”
- critical situation will occur when measurement value will be greater than
threshold value
„SEtP”
of this relay,
“LESS”
- critical situation will occur when measurement value will be lower than
threshold value
„SEtP”
of this relay,
“on”
- critical situation will occur when particular relay will be closed,
“oFF”
- critical situation will occur when particular relay will be opened.
The critical situation of the bargraph
will occur in case when any of defined
situation occur.
The critical situation of the bargraph
is signalized by inverting of
colours (red to green, and green to red)
“
Lo C
”, “
Hi C
” - these parameters define measurement range of the bargraph. The percentage
value showed by the bargraph is calculated due to measured value (and showed
on digital display).
“Lo C”
parameter defines the value appropriate to 0% on the
bargraph.
“Hi C”
parameter defines the value appropriate to 100% on the
bargraph. Measurements between
“Lo C”
and
“Hi C”
are recalculated due to
formula:
P
=
W
−
"Lo C"
"Hi C"
−
"Lo C"
×
100
%
where:
„P”
denotes percentage value showed by the bargraph,
„W”
- denotes value showed on digital display (the measurement value)
Value of
“Lo C”
can be greater than value if
“Hi C”
. In this case the conversion
characteristic of the bargraph is upturned (it means that when measurement value
raises then the bargraph value falls, and when measurement value falls the
bargraph value raises).

This parameter allows the user to set brightness of the LED display, brightness can be
