Fault

Error / Cause

Check / Solve

“30“ flashing Data distortion within adjustable pa-

rameters (CRC-Error)

Check all parameters via WSSoft and
reset to standard options, check installa-
tion of supervision cables (1 kOhm), do
not run supervision cables in same con-
duit with other cables, use shielded
spark plug caps,

“31“ flashing CRC-Error within fixed parameter

Internal device error, send to vendor for
evaluation

“- -“

Power switch turned off

Control functions not available when box
is not turned on, press 0/1 button to
power box up

“Pb“ flashing Profibus data transmission disturbed,

CBF cannot communicate with bus
master

Bus wires broken/interrupted, bus wires
switched in connectors,  A and B termi-
nals switched,  insufficient shielding,  in-
correct system termination,  activate
termination on first and last device only,
incorrect Profibus address assigned,
bus wires too long, install repeaters or
reduce baud rate,  increased baud rates
increase transmission times
