Output testing
In addition to just viewing the current process values you may also check
the output channels. This means that you can output any current value
between 0 and 20 mA via an analogue output for testing purposes. A
message output can be set to
Contact closed
or
open
, and you may also
output pulses for testing reasons. However, only one output can be
switched into the test mode at the same time.
Proceed as described below:
1) Select the desired output channel, and press the Menu key
afterwards.
2) Select the
Test on
submenu.
The
Test value
line is selected automatically. Press the Enter key to
switch to the edit mode. If you enter a new value now and confirm it
by pressing the Enter key, this value will be output via the selected
output.
In the activated test mode the
Test value
indicated in the last line is
no longer crossed out. The
Output value
menu item also indicates
the output test value.
3) To quit the test mode, press the Menu key again and confirm the
Test off
menu item.
Note:
You may also quit the test mode by quitting the current display, for
instance via
Back
or by selecting a different channel.
