What to do if controlled equipment does not respond to manual Ametek switch actuation test?
If the controlled equipment isn't responding when you manually actuate the Ametek switch, the issue might stem from the level sensing components: the floats, stems, or magnetic attraction sleeves. Also, make sure liquid is actually entering the float chamber; a closed valve or plugged piping could be the culprit.
What to do if Ametek Magnetrol 3 Switch mechanism fails to actuate?
If the Ametek switch mechanism isn't actuating, ensure the control is installed within 3° of vertical as specified. If the switch still doesn't work, replace it immediately.
What to do if Ametek Magnetrol 3 Switch float is filled with liquid or collapsed?
If the Ametek switch float is filled with liquid or has collapsed, it must be replaced immediately.
