The possible errors are grouped into the follo-
wing three categories in the ORPHEE software:
Error
category General meaning Valve terminal diagnosis
Internal
errors Internal errors concern the
general function of a hardware
module or the FIPIO slave. Not relevant
External
errors External errors are device-
specific errors which are
registered by the FIPIO field bus
slave. Error entries of the valve
terminal:
EF1 = External error 1 = V
out
*)
EF2 = External error 2 = V
val
*)
EF3 = External error 3 = V
sen
*)
EF4 = External error 4 = Sh.
c./o.

Logical
errors Logical errrors refer to
parametrizing errors. Not relevant
The error messages of internal and logical errors are identical with all
devices/field bus slaves. The valve terminals create device-specific messages
only with external errors.

The diagnostic information of the valve
terminal has the following meaning:
Diagnostic
information Meaning Cause
Short
circuit/
overload Monitors the electrical outputs
of the output modules. Short circuit
or
overload
V
sensors
(V
sen
)
Monitors the supply voltage of
the inputs (sensors). Internal fuse triggered
V
outputs
(V
out
)
Monitors the operating voltage
of the valves and electrical
outputs (no voltage available
e.g. EMERGENCY STOP). Operating voltage at pin 2 of
operating voltage connection
< 10 V
V
valves
(V
val
)
Monitors the tolerance of the
operating voltage of the valves
and electrical outputs. Operating voltage at pin 2 of
operating voltage connection
< 21.6 V
