4.2.4 Monitoring of rectifier load

If the power system is equipped with more rectifiers as necessary (redundancy), these spare rectifiers

can be configured as redundant.

All rectifiers within the power system remain operating; merely the signalling is changed in the case of

a unit f

ailure.

At the menu "CAN Devices Cnt

" (section 6.4.2) two types of signaling concerning redundancy are

settable.

1. Modus “Redundancy type 1”

(Redundancy event is active as soon as redundancy is not available).

Example

: Four rectifiers are fitted, two rectifiers are set as redundant.

 If one rectifier failes, the UPC4 generates the event "REC No CAN".

 If two rectifiers fail, the events "REC No CAN" as we

ll as "REC Redundant" are generated.

2. Modus “Redundancy type 2”

(Redundancy event is active as soon as the redundant rectifiers and additional at least one more

are fail

ed).

Example

: Four rectifiers are fitted; two rectifiers are set as redundant.

 If two rectifier failes, the UPC4 generates only the alarm messages "REC No CAN".

 If three rectifiers faile, the UPC4 generates the alarm messages "REC No CAN" and "REC

edundant" as well.

For details please see section 6.4.5 "System parameters".
