10.3 Inverting analog inputs E1 and E2
After the hardware adjustments have been carried out through the internal jumpers and programming the signal or sensor
type, an inversion of the inputs can be carried out.
Factory setting for Inverting inputs = “OFF“ (if input activated )
(signal: 0-10 V, 0-20 mA, 4-20 mA)
For activation using inverted default signals or sensors with inverted output signals proportional
to the measurement range, switch inverting to “ON”
(Signal: 10-0 V, 20-0 mA, 20-4 mA)
Ziehl-Abegg sensors generally do not work with inverted output signals
(i.e., these are not suitable for an inverted evaluation)
e. g.:
DSG200 0-10 V proportional 0-200 Pa
MAL1 0-10 V proportional 0-1 m/s
DSF2-25 4-20 mA proportional 2-25 bar
In sensors with inverted outputs, 0 V or 4 mA must correspond to the final value
of the
measurement range.
e. g. pressure sensor 10-0 V proportional 0-200 Pa
