Appendix D:

- Corrected length and digital bank parameters for A5D1 Fast Meter data block.

990628 This revision includes the following changes:

- Updated MIRRORED BITS™format throughout to reflect new trademark.

Section 1:

- Added phase pickup setting 50P4P to Table 1.1. Setting 50P4P is set (in A

secondary) when Min. trip-phase is set (in A primary) in the EZ setting routing

(SET EZ command). Phase pickup setting 50P4P controls single-phase

elements 50A4, 50B4, and 50C4, listed in Table 1.2. These single-phase

elements indicate faulted phases for the trip operations counters (see

discussion on trip operation counters in the Breaker/Recloser Contact Wear

Monitor subsection in Section 8: Breaker/Recloser Monitor, Battery System

Monitor, and Load Profile Functions).

Section 3:

- Added explanation to the Synchronism Check Elements subsection for the

new angle setting option for the SYNCP (synchronizing phase) setting.

Synchronism check can now be accomplished for synchronism check voltage

input VS connected phase-phase or beyond a delta-wye transformer. Setting

SYNCP accounts for the constant angle difference between reference voltage

input VA and synchronism check voltage input VS.

Section 7:

- Clarified the operation of the latch control switches when the SEL-351R

Recloser Control loses power (see the Latch Control Switches subsection).

Section 8:

- Added discussion on the per-phase and ground trip operation counter

information now available via the BRE A command in the Breaker/Recloser

Contact Wear Monitor subsection.

Section 9:

- Expanded the setting range for the SYNCP (synchronizing phase) setting to

accommodate compensation angle settings for synchronism check (Settings

Sheet 8 of 23).

- Added the MB8A and MB8B serial port protocol settings options for

MIRRORED BITS protocol operating on communication channels requiring an 8

data bit format (Settings Sheet 23 of 23).

Appendix I:

- Explained the MB8A and MB8B serial port protocol settings options for

MIRRORED BITS protocol operating on communication channels requiring an 8

data bit format.

990323 This revision includes the following changes:

Section 1:

- Changed logic in Figure 1.11 and Figure 1.12 to allow high current trips to

operate if auto-reclosing is nonexistent.

- Changed logic in bottom of Figure 1.23 to allow time-overcurrent pickups

51N1 and 51N2 to indicate ground current above Min. trip-ground level for the

drive-to-lockout logic (51N1 and 51N2 don’t have the built-in 2 cycle delay

that 50N6 has - thus, 51N1 and 51N2 are useful indication for instantaneous

trips).

- Changed logic in Figure 1.54 to allow time-overcurrent pickups 51N1 and

51N2 to indicate ground current above Min. trip-ground level for the fault-type

trip target LED “G.”

Section 3:

- Changed routing of Directional Control to Figure 3.8 (67N elements) and

Figures 3.16 and 3.17 (51NT elements)

Section 4:

- Added zero-sequence voltage polarized, neutral current directional elements to

Best Choice Ground Directional™ Logic.

- Inserted the following drawings:

- Corrected references to the number of available event reports, depending on

the length of event report format chosen: 15 or 30 cycles (twenty-eight 15-
