Installation
Fix the controller e onto a 35 mm DIN rail which has an electrically safe
ground connection. The protection rating of the unit is IP20, therefore
it should be mounted in a protected location (e.g. control cabinet).
Ensure a condensation-free environment. Avoid excessive dust,
vibration and shock. The air circulation through the vents must
not be impeded.
Avoid installation in direct vicinity of frequency inverters.
Electrical connection
Disconnect the installation from power. Connect the unit as indi-
cated on the terminals. Never connect the minus potentials to
each other or the minus potentials to the FE connection.
Ensure an electrically safe ground connection between AS-i con-
troller
e
(terminal FE) and ground connection of the unit.
Supply the controller
e
with a 24 V DC voltage (20...30 V PELV), e.g.
from the 24 V power supply DN2011 of ifm electronic. The connection
is made to the ter24 V and 0 V.
Operating and indicating elements
Information concerning the state of the master (AC1355)/masters
/AC1356) and the connected system is given via three diagnostic LEDs
on the controller
e
.
• LED PWR/COM lights:
AS-i voltage present, at least one slave
was detected
• LED PWR/COM flashes: AS-i voltage present, but no slave was
detected correctly
• LED PROJ lights:
Projection mode active, the configuration
monitoring is deactivated
• LED PROJ flashes:
Projection mode active, changeover to
protected mode not possible as a slave
with the address 0 is connected
