CPV..-GE-ASI-8E8A-...
3.4 Connecting the AS-Interface bus and load voltages
PLEASE NOTE
The sensor supply for the inputs is provided via the AS-Inter-
face bus. The valves must be supplied separately with 24 V
via the load voltage connection.
The AS-Interface type CPV..-GE-ASI-8E8A-... has an inte-
grated watchdog function which resets the outputs if there is
a bus communication failure.
WARNING
Use only power units which guarantee reliable isolation of
the operating voltages as per IEC 742/EN 60742/VDE/0551
with at least 4 kV isolation resistance (protecetd extra low
voltage, PELV).
Switch power packs are permitted if they guarantee reliable
isolation in accordance with EN 60950/VDE 0805.
