A After the test button is pressed, the DC-PNP output is switched off for at least 10 s (I < 100 µA) even if the
button is pressed for < 10 s. If the test button is pressed for > 10 s, the DC-PNP output remains switched off
(I < 100 µA) until the test button is released. The DC-PNP output is then switched on again.

A After the test button is pressed, the relay is de-energized for at least 10 s even if the button is pressed for <
10 s. If the test button is pressed for > 10 s, the relay remains de-energized until the test button is released.
The relay is then energized again.
