Specifications in % refer to the span = InH - InL (not for correcting variable).
Ü This function can be switched off: Press key D until '----' is displayed.
* The displayed value depends on the decimal point.
Ö With Con1 = ..72, an output limitation is not possible. ttP is independent and
with ----, SH is valid. SH is affected by ttP: SH = SH or
SH = 2 . ttP . Pb1/ tt, the higher one of the two is valid.
ä Calibrating the universal input for potentiometric transducers:
Take-over the values: Select parameter P0, place transducer at 0%. Wait 6 s.
Press M and D, 0 is dispayed. Press M, P100 is displayed. Set transducer to
100%, wait 6 s. Press M and I, 100 is displayed. Press M.
Adjusting the display: InL / InH are the display values for 0%/100%.
# Only with input 0/4...20 mA, 0...10 V, potentiometric transducer or Pt 100
(for Pt100 only 0 / 1, for ratio input only 2).
< Only with input 0/4...20 mA, 0...10 V or potentiometric transducer. When changing
these values, all set-points and limit values must be matched. For this, leave
parameter level, re-select it and adjust values as required with I and D.
> With a given variable X2 (e.g. air flow), the ratio controller alters
variable X1 (e.g. fuel flow) until the adjusted ratio is reached.
The required ratio can be set from 0,01...9,99. The zero of variable
X1 is adjustable from -99,9...99,9% of X
X1 _ oFFS = 0,01...9,99
