LATCHING RELAY VERIFICATION
Contact test:
Check with the external wiring diagram that all the auxiliary contacts of the latching relay are open and,
therefore, there is no continuity between them.
Apply voltage to terminals +A1 y –A4 and verify that latching relay contacts operation time is below 25 ms.
Verify that all auxiliary contacts have changed their position to closed and that there is continuity between
each pair of them.
Apply voltage to terminals +B9 and –B12 and verify that latching relay contacts opening time is below 20 ms.
Check that all auxiliary contacts have changed to their default position (open) and, therefore, there is no
continuity between each pair of them.
Lamp:
Apply the latching relay rated voltage to terminals CN-A6 and CN-A9 and check that the button lightens up.
Switch the voltage off and check the lamp turns off.
Press the button and check for continuity between CN-A7 and CN-A8
