4.2 AS-i diagnosis LEDs
The three diagnosis LEDs on the front of the AS-i DP -Gateway give information concerning the state
of the AS-i master and the connected AS-i system. The LEDs have the following meaning:
PWR/COM On: AS-i voltage (
P
o

r
) present and
com
munication with at least one
slave has been established
Flashing: AS-i voltage ( Power) present but no slave communication established
P R O J On:
Proj

Flashing: Projection mode active, switch to protected mode not possible
because a slave having address 0 is connected
CONF / PF On:
Projected and current
conf

Flashing:
P
eriphery
f
ault on at least one of the connected slaves
4.3 Connecting the slaves
The AS-i units feature short-circuit and reverse polarity protection, nonetheless connections of for
example control cabinet modules should be made only after power has been turned off. Many slaves
of this type have a jumper which when connected causes the slave to be deactivated. Leave this
jumper connected at this point.
When using SmartLine modules please remove the combicon plug connected to AS-i +/-.
AS-i field modules usually consist of a lower part for connection of the yellow flat cable and an upper
part which contains the electronics. Place the yellow cable in the lower part but do not screw the upper
part on yet.
