Redundant a.c. Mains Supply and Redundant Power Supply Regulators
(Total redundancy)
In an Advant Controller which includes total power supply redundancy, the probability for a
shut down caused by a single power supply failure is extremely small. That is the controller will
still be operational when a single failure exists. Diagnostics support is available. A detected
failure must be taken care of as soon as possible to regain redundancy. Normally a faulty unit
can be replaced on line.
Two scenarios are described. A single failure in the controller power supply (Scenario C).
And a single failure in an I/O subrack power supply (Scenario D).
These situations are notified by:
Scenario C
•
An operator station connected to this controller.
Indications obtained by:
–
System message
–
System status display.
The faulty power supply branch A or B is pointed out.
Failure in the 5 V regulators is pointed out.
(see
Section 5.5.2.1, System Status and Plain Language System Messages
Scenario D
•
An operator station connected to this controller
Indications obtained by:
–
System message
–
System status display.
The faulty power supply branch A or B is pointed out.
Failure in the 5 V regulators is pointed out

General
Fault finding in the controller cabinet is carried out as follows.
Before replacing a power supply unit or a fuse or resetting a MCB try to check for a reason of
the fault. If deemed too time consuming, it is always possible to try the easy way and “look for
the smoke”.
