5.1 Process Sequence
Figure 8 - Sequence control
As soon as the control assembly is supplied with voltage, se-
quence control starts.
Initially, load interrupter switch Q4 remains open. Once the initiali-
sation phase is complete and if no deactivating faults are pending,
Q4 is closed. The switch is only opened by deactivating faults
while the equipment is in operation ( Chapter 5.7.3 - Table of
Faults).
The output contactor K7 remains open initially. The contactor is
switched by the sequence control.
5.1.1 "OFF" Status
The equipment has been switched off logically via the DOU or the
master control system. The equipment is running without faults;
the monitoring systems are not activated. In this status, no power
is fed into the mains.
Change of status:
The status can be switched from "OFF" to "Waiting for feed condi-
tions" by switching the equipment on via the DOU and/or the mas-
ter control system.
