These firmware differ from previous versions as
follows:
− Fixed scaling problems with the directional elements
and fault locator associated with the SEL-351-2, -3,
and -4 Relays that have 300 V PTs.
− Added the MB8A and MB8B serial port protocol
settings options for MIRRORED BITS protocol
operating on communication channels requiring an
eight bit data format
− Expanded the setting range for the SYNCP
(synchronizing phase) setting to accommodate
compensation angle settings for synchronism check
− Changed DNP mapping command so that it now
requests a confirmation before saving the map
modification
− Corrected Loss-of-Potential V
1
unlatch threshold for
300 V input models.
