The diagnostics information of the four status
bits is coded and has the following meaning:
Diagnostic
information Meaning Cause
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
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
sensors
(V
sen
)
Monitors the supply voltage of
the inputs (sensors). Internal fuse triggered
Short
circuit/
overload Monitors the electrical outputs
of the output modules. Short circuit
or
overload
