Module bus – emergency shutdown

With system conditions that may damage or destroy the devices, it is important that the output stages of the devices can be inhibited quickly. The module bus master has an emergency shutdown function that is triggered with critical faults. Each station may activate the emergency shutdown.

Emergency shutdown of the power supply module is only performed in case of overvoltage on the A-side or the B-side. If the emergency shutdown is triggered by another station, fault "26.2 Emergency shutdown" is executed. This fault can only be reset if no other station triggers the emergency shutdown.
