Diagnostic information Description Function
Short circuit/overload at output Output short circuited or over-
loaded Monitors of electrical outputs of
output stages
V
valves
<
21.6V Load voltage on pin 2 (valves
and outputs) of the operating
voltage connection
<
21.6 V
Monitors the tolerance of the
load voltage for valves and elec-
trical outputs
VU
outputs
<
10V Load voltage on pin 2 (valves
and outputs) of the operating
voltage connection
<
10 V
Monitors the load voltage for
valves and electrical outputs
(no voltage present, e.g. emerg-
ency stop)
V
Sensor
<
10 V Operating voltage on pin 1
(electronics and inputs) of the
operating voltage connection
<
10 V
Monitors the operating voltage
for inputs (sensors). Shows
whether internal fuse has been
triggered (fuse on node or at
least one electronic fuse on the
input module
