6.2 DIGITAL INPUTS
COMMANDS
A function is assigned, through
the configuration procedure to
each IL1, IL3 and IL3 digital
input. (see the parameters set-
ting at tab. 10 at page 30).
The configured function is acti-
vated when the digital input (free
voltage contact or open collec-
tor output) is in the On state
(closed). It is deactivated by set-
ting the input to the Off state
(open).
The activation of the function
through the digital input has the
highest priority than through the
keypad or through the serial
communication.
