Description of
32 A J March 2006
Not released to production.
Phase rotation function added. Can select phase rotation as
ABC or ACB for all 3 phase current and voltage inputs. Can
also individually select which 2 phases are swapped for any
of the 3 phase current and voltage inputs. New menu column
'System Config' with phase rotation settings.
In P34x relays the maximum number of disturbance recorder
analogue channels has been increased in most relay models
so that all analogue inputs can be recorded. In the P341 the
maximum number of recorded channels has remained as 8
but now channels can be set as unused if required.
Number of PSL DDB signals increased from 1023 to 1408
and DDBs re-organized. This means that the PSL created in
version 32 software is not compatible to PSL created in
previous software versions and vice versa.
Setting Group selection via 2 new DDB signals makes it
possible to select a setting group via any opto input or
remotely via a Control Input. Previously, the 4 setting groups
could be selected using fixed opto inputs, 1 and 2.
An 'Any Trip' DDB has been created to allow any contact(s)
to be used as the trip indication. Previously, the Any Trip
signal was defined as operation of Relay contact 3. The Any
Trip signal operates the Trip LED, initiates the breaker fail
logic and maintenance counters and is used in the fault
recorder logic.
Minor changes to description of CT and VT Ratio settings.
Number of maintenance records increased from 5 to 10.
