Electrical Connection; Operating And Indicating Elements - IFM Electronic AS-i CONTROLLER e AC1355 Montageanleitung

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 (terminal FE) and ground connection of the unit.
e
Supply the controller
from the 24 V power supply DN2011 of ifm electronic. The connection
is made to the terminals +24 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
• LED PWR/COM lights:
• LED PWR/COM flashes: AS-i voltage present, but no slave was
• LED PROJ lights:
• LED PROJ flashes:
with a 24 V DC voltage (20...30 V PELV), e.g.
e
.
e
AS-i voltage present, at least one slave
was detected
detected correctly
Projection mode active, the configuration
monitoring is deactivated
Projection mode active, changeover to
protected mode not possible as a slave
with the address 0 is connected
