“AL”
- this parameter defines the relay reaction when some critical situations occurs:
“noCH”
- relay do not change his state,
“on”
- relay will be turned
ON
,
“oFF”
- relay will be turned
OFF
.
If parameter
“modE”
is set to
“on”
,
“oFF”
,
“in”
or
“Out”
the “critical situation”
means that allowable measurement range is exceeded.
•
If option
“noCH”
is selected for
“AL”
parameter, behaviour of the relay may
depend on
“FiLt”
parameter
in some cases
. If
“FiLt”
is set to big value and the
input signal drops, result value of the measure will change slow, causes of
turning on or off relay due to thresholds values. The critical situation is slowly
detected, so it is impossible to predict the relay state in that situations.
•
If parameter
“AL”
=
“on”
, the relay will be turned on in the critical situations,
even if his parameter
“modE”
=
“noAC”.
7.3.2.
“inPt” menu
This menu presets the measurement input:
“CHAr”
- this option presets type of the conversion characteristic, and can be set to:
“
Lin”
- linear
“Sqr”
- square
“Sqrt”
- square root
When one of those characteristics is chosen display
range is defined by
“Lo C”
and
“Hi C”
.
“USEr”
- user defined characteristic. Maximal length 20 points. Every point is
defined by user. Adding, Editing and Deleting of points is done by options
“AddP”
,
“EdtP”
,
“dELP”
(
“InPt”
menu) respectively.
If user defined characteristic is selected, and if number of defined points is lower
than 2 then warning
“Errc”
is displayed in measurement mode.
The process of displayed result calculation is described in details in
DISPLAY VALUES
CALCULATION
paragraph.
“FiLt”
- this parameter sets filtration rate. It can be set to values from 0 (no filtration ) to 5
(strongest filtration – time window about 3 sec).
“Pnt”
- decimal point position. It can be set to one of:
“ 0”
,
“ 0.0”
,
“ 0.00”
,
“0.000”
Decimal point position is changed by
[^]
,
[v]
buttons.
“Lo C”
“Hi C”
These parameters describe the values displayed for minimum and maximum input
current.
“Lo C”
parameter defines the value displayed when input current is equal
4 mA, and
“Hi C”
parameter defines the value displayed for 20 mA of input current.
Available range for these parameters: -999 ÷ 9999. Negative values can be set by
entering
'-'
sign on the first position (by use of
[^]
,
[v]
buttons).
