INPUTS
The
RECmax Lpd
has one key:
EXT
input
(terminals 12 and 13 in
) enables the remote control of the main switch, trip
or reset of the switch depending on its status.
The input is activated when terminals 12-13 are short circuited with an external contact (volt-
age-free), for example a button.
EXT
input acts as an edge-triggered bistable, T-type input, i.e.,
the status of the main switch changes on each pulse, if the switch is open it closes, if it is closed
it opens.
