Error Text Meaning What to Do
00001
B
1
D
Short circuit Short circuit because, for example:
Sensor wiring to P potential short-circuited
Sensor wiring to M potential short-circuited
Output wiring to P potential short-circuited
Output wiring to ground short-circuited
Correct the
process wiring

D
Upper limit
violation
Value is above the overrange Correct the
module/actuator
match
01000
B

D
Lower limit
violation
Value is below the underrange Correct the
module/actuator
match
01001
B

D
Error Error, for example, because:
Load voltage at the output
Sensor supply
Hardware error in the module
Contactor is welded or jammed
The switching element has reached the end of
its life
Replace the
module.
