Appendix A, Hardware Modules gives module/unit information including description of the
function, block diagram, technical data, maintenance parts and so on.
Two variants of power supply system are dealt with:
• a.c. mains supply (no redundancy)
• Redundant a.c. mains supply and redundant power supply regulators (total redundancy).
The general instructions also are valid for d.c. mains installations and partial redundancy.
a.c. Mains Supply
(no redundancy)
In a power supply system which includes no redundancy a serious power failure will result in
the controller total shut down (Scenario A) or a loss of an entire I/O subrack functionality
including all the I/O modules (Scenario B).
These situations are notified by:
Scenario A
• An operator station connected to this controller.
Indications obtained by:
– System message
– System status display (see Section 5.5.2.1, System Status and Plain Language System
Messages)
– Lost communication
• Run/Alarm relay contact opens
• Process behavior
• Green RUN LED on processor module PM511 is OFF
• All LED’s in the cabinet are OFF. Besides those included in the RAM backup power
supply system. Thus:
– SB510/511, the LED BP will be ON
– PM511, the LED BC will be ON.
Scenario B
• An operator station connected to this controller
Indications obtained by:
– System message
– System status display (see Section 5.5.2.1, System Status and Plain Language System
