Error detection and problem solutions

7.1

LEDs

The valve interface is provided with 6 LEDs at the front of the device which inform about the status of the
device and about errors related to the hardware which must be eliminated locally under normal circumstanc-
es.

Cause
Elimination of error
Cause
The parameterisation
data stored in the
device were faulty and
replaced by the default
settings.
Simulation allowed by
setting the switch 1.
The target mode of the
block is OOS.
Elimination
• Check power supply.
• Check wiring of F
OUNDATION
• Check LAS.
Send device to manufacturer.
• Inform about exact error in device, re-
fer to diagnosis messages.
• Check PFC and valve line of affected
channel.
Elimination
Repeat parameterisation. If this error
occurs repeatedly, send the device to
Pepperl+Fuchs for repair.
Send device to Pepperl+Fuchs for
repair.
Check whether simulation shall be
allowed.
Set block to "Auto" mode.
