6.11.2.3 How to depassivate modules or channels
Introduction
The passivation symbol is displayed in the faceplate in order to ensure that the discrepancy
of a redundant module or its failed channels can be detected by the maintenance engineer.
As long as the discrepancy time is active, maintenance required and a message are displayed
in the message system in the faceplate of the module.
If, moreover, a long-term discrepancy is detected, the module/channel is passivated. This
results in a loss of redundancy. The module or the channel is indicated as "Faulty" in the block
icon. The maintenance demanded, the symbol for depassivation and a message are displayed
in the message system in the faceplate.
If the cause of the discrepancy has been remedied, the depassivation can be carried out with
the icon in the faceplate.
