SOMMER USH-9, Руководство пользователя

ID Option Description
1 off (default) Analog outputs are inactive.
2 just during TRIG Analog outputs are only active, if an external signal is
present at the TRIG input. The outputs are high as long as
the signal at the TRIG input is high.
3 always on Analog outputs are permanently active.
NOTE The USH-9 delays analog data acquisition by 200 ms. If Status is set to
just during TRIG , the analog output must be read with a delay of min. 200 ms
after the trigger has been sent. This ensures that the analog measurement has
sufficiently stabilized. As the analog measurement itself requires some time,
the result should be read with a delay of
measurement du min. 1
second .
13.4 Scaling
The variables and their analog output range are configured as described below.
NOTE
The analog outputs may return currents between 0 and 21 mA. However, the
accuracies stated in the specifications are only valid for signals within 4 to 20
mA!
If the measured value falls below or exceeds the 3.9…21 mA range, 3.9 mA and
21 mA, respectively, are returned. An exception are the measurement values
99999998
and
99999997
, which return a 3.8- mA and 3.7- mA signal,
respectively.
ATTENTION The 4-mA output should correspond to a measurement value at or
below the expected minimum! With low current output the accuracy tends to
decrease and cross-talk with other analog channels may occur.
13.4.1 IOUT 1
The measured level or distance can be returned as an analog 4…20 mA signal on pin 8 of the MAIN
connector. Select level or distance in
IOUT1, function . The span and offset have to be selected to
