Proof Test
Within the test, the switches are used. The correct settings for the application
must be established again subsequent to the test.

Attach the input voltage subsequently
to each input and check if only the
related output is activated. For this test,
the line fault detection DIP switches
must be in OFF position (position II).

Attach the input voltage subsequently
to each input and check that no output
is switching. For this test, the line fault
detection DIP switches must also be in
OFF position (position II). The
OFF LED is blinking.

For this test, the line fault detection DIP
switches must be in ON position
(position I) for all four signal paths.
Deactivate all inputs. The OFF LED and
the four channel switching status LEDs
must be blinking red.
