15.3.1 Measuring Range of the Analog Output
After an analog output has been activated in the program branch
Output Options
, the measuring range of the source
item has to be entered.
Select
sign
if the sign of the measured values is to be considered for the output.
Select
absolut
if the sign is not to be considered.
Enter the lowest expected measured value. The unit of measurement of the source item
will be displayed.
Zero-Scale Val.
is the measured value that corresponds to the lower limit of the output
range as defined in section 15.1.1.
Enter the highest expected measured value.
Full-Scale Val.
is the measured value that corresponds to the upper limit of the output
range as defined in section 15.1.1.
Example:
output: current output
output range: 4…20 mA
Zero-Scale Val.
: 0 m³/h
Full-Scale Val.
: 300 m³/h
volumetric flow rate = 0 m³/h, corresponds to 4 mA
volumetric flow rate = 300 m³/h, corresponds to 20 mA
15.3.2 Function Test
The function of the installed output can now be tested. Connect a multimeter to the installed output.
Select
yes
to activate the output. Press ENTER.
Enter a test value. The value has to be indicated on the connected multimeter.
Press ENTER.
Select
yes
to repeat the test. Press ENTER.
Example:
output: current output
output range: 4…20 mA
Zero-Scale Val.
: 0 m³/h
Full-Scale Val.
: 300 m³/h
Test value
= 150 m³/h (Middle of the measuring range corresponds to 12 mA)
If the meter indicates 12 mA, working current output.
15.4
Activation of a Binary Output as a Pulse Output
A pulse output is an integrating output which emits a pulse when the volume or the mass of the medium which has passed
the measuring point reaches a given value (
Pulse Value
). The integrated quantity is the selected physical quantity. Inte-
gration is restarted as soon as a pulse is emitted.
Select
yes
to activate the output. Press ENTER.
This error message will be displayed if the flow velocity has been selected as the physical
quantity.
The use of the pulse output is not possible in this case because integrating the flow velocity
does not result in a reasonable value.
Note!
The menu item
Pulse Output
will only be indicated in the program branch
Output Options
if a
pulse output has been installed.
