These errors can only be reset by switching the power supply for the safety terminal off
and back again.

7.3 Troubleshooting
m Check wiring, check 24 V supply
m SO4000: Pay attention to minimum current of 20 mA
m The SAF module for the b maXX 5000, which is directly controlled via SO4000 must
cope with this ("Separate Grounds" of the type: BM5-O-SAF-002-001-xxx-#01 or
BM5-O-SAF-003-001-xxx-#01 and the adapter for the safety-I/O-terminal).
m FSoE communication problems:
n Checking the address setting on the safety terminals (may be assigned once only)
n Check if EtherCAT bus is running synchronously
m The setting of the cycle time in the ring must be the same all over
m The user must activate the bus synchronization in all b maXX 5000 controllers
(there is no automatic setting, as the EtherCAT slave is permanently integrated in
the controller. The device is delivered as single device without a configured bus
connection)
m Check grounding at the machine
m Regard EtherCAT cabling sequence by starting from the EtherCat master (for ex-
ample, if b maXX 5000 controllers are integrated):
Cable of EtherCAT master → Connection at (input) terminal “X3” (of the b maXX
5000), of (output) terminal “X4” → go to the next EtherCAT slave
n Incorrect mapping of the FSoE participants in the configuration software
n Mapped participants are missing at the EtherCAT bus
