37 FEL61 switching behavior and signaling
A After the test button is pressed, the load is switched off for at least 10 seconds (I < 3.8 mA) even if the button
is pressed for < 10 seconds. If the button is pressed for > 10 seconds, the load remains switched off
(I < 3.8 mA) until the test button is released. The load is then switched on again.

38 FEL62 switching behaviour and signaling
A After the test button is pressed, the DC-PNP output is switched off for at least 10 seconds (I < 100 µA) even if
the button is pressed for < 10 seconds. If the button is pressed for > 10 seconds, 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.
