0 [No error] No fault −
1 [General diagnosis] General diagnosis (module−
specific error)
See manual for the relevant
module
2 [Short circuit] Short circuit/overload in sen
sor supply (SCS) or at output
(SCO)
Eliminate short circuit/over
load (see manual for the spe
cific module)

input/output
Check and, if necessary, re
place the cable and connec
ted sensors/actuators.
4 [Short circuit in actuator
supply]
Failure of load voltage supply
due to short circuit/overload
(on output side)
Check connected actuators
as well as their connections
