3.6 Setting tool for all input and output values
Definitions: In
min
= smallest input value
In
max
= largest input value
Out
min
= smallest output value
Out
max
= largest output value
OS = output span (take from table on Pg 22)
EV = upper end value (take from table on Pg 22)
1. Select output range of unit (according to table on Pg 22) so that Out
min
and Out
max
are within the output range.
2. Calculate the following auxiliary quantities:
3. Set all DIP switches to OFF.
4. Calculate input range IR, set output range and offset OF with DIP
switches.
4a. If the calculated offset OF does not correspond with an offset which can
be set with the DIP switches, set the closest offset (see table on page 22)
and activate the zero potentiometer (switch 2-5 OFF), short-circuit input
and adjust output to value Out
min
– (In
min
x F).
4b. If the calculated input range IR does not correspond with a range
which can be set with the DIP switches set the largest range within
0.33 x IR … 3.30 x IR (see table on page 21) and activate the span
potentiometer (switch 2-4 OFF), modulate input with value
≠
0 (see table
on page 21 for terminals) and adjust output to required value (e.g. set
In
max
, adjust to Out
max
).
