The group error LED (LED E) can illuminate alone or in conjunction with other
LEDs. Detailed information about the occurred group error is available in the
section "Diagnostics".
Behavior when group error LED (LED E) is flashing
A flashing group error LED (LED E) indicates that the PROFIsafe I/O module
has detected an internal safety critical error. The cause can be a defect in the
PROFIsafe I/O module or an environmental EMC error. In this case, switch off
the PROFIsafe I/O module completely and the switch it back on.
If the problem occurs several times, it points to a defect in the PROFIsafe I/O
module. In this case, return the PROFIsafe I/O module to WAGO Kontakttechnik
GmbH & Co. KG for fault analysis.
