Behavior when group error LED (LED E) is flashing
A flashing group error LED (LED E) indicates that the F I/O module has detected
an internal safety critical error. The cause can be a defect in the F I/O module or
an environmental EMC error. In this case, switch off the F I/O module completely
and the switch it back on.
If the problem occurs several times, it points to a defect in the F I/O module. In
this case, return the F I/O module to WAGO Kontakttechnik GmbH & Co. KG for
fault analysis.
