FOR THE SEL-351 RELAY Date
SEQUENTIAL EVENTS RECORDER AND LOAD PROFILE SETTINGS (SERIAL PORT COMMAND SET R)
Date Code 20001006
Sequential Events Recorder settings are comprised of three trigger lists. Each trigger list can
include up to 24 Relay Word bits delimited by spaces or commas. Enter NA to remove a list of
these Relay Word bit settings. See Sequential Events Recorder (SER) Report in Section 12.
SER Trigger List 1 SER1 =
SER Trigger List 2 SER2 =
SER Trigger List 3 SER3 =
Load Profile settings are only available in Firmware Versions 1, 2, 3, and 4. See Load Profile in
Section 8.
Load profile list
(15 elements max., enter NA to null)
LDLIST =
Load profile acquisition rate (5,10,15,30,60
min)
LDAR =
LDLIST may contain any of the following elements (delimit with spaces or commas):
ELEMENT QUANTITY RECORDED
IA, IB, IC, IN Phase and neutral current magnitudes
VA, VB, VC, VS Phase and sync voltage magnitudes
IG, I1, 3I2, 3V0, V1, V2 Sequence current and voltage magnitudes
VDC Battery voltage
FREQ Phase frequency
MWA, MWB, MWC, MW3 Phase and 3 phase megaWATTs
MVARA, MVARB, MVARC, MVAR3 Phase and 3 phase megaVARs
PFA, PFB, PFC, PF3 Phase and 3 phase power factor
LDPFA, LDPFB, LDPFC, LDPF3 Phase and 3 phase power factor lead/lag status
(0 = lag, 1 = lead)
IADEM, IBDEM, ICDEM, INDEM, IGDEM,
3I2DEM
Demand ammeter quantities
MWADI, MWBDI, MWCDI, MW3DI Phase and 3 phase demand megaWATTs in
MWADO, MWBDO, MWCDO, MW3DO Phase and 3 phase demand megaWATTs out
MVRADI, MVRBDI, MVRCDI, MVR3DI Phase and 3 phase demand megaVARs in
MVRADO, MVRBDO, MVRCDO, MVR3DO Phase and 3 phase demand megaVARs out
MWHAI, MWHBI, MWHCI, MWH3I Phase and 3 phase megaWATT hours in
MWHAO, MWHBO, MWHCO, MWH3O Phase and 3 phase megaWATT hours out
MVRHAI, MVRHBI, MVRHCI, MVRH3I Phase and 3 phase megaVAR hours in

Note: In versions of the relay with delta-connected voltage inputs, the per-phase energy and power
values (both instantaneous and demand) and 3V0 will not be available. Also the per-phase
voltages are replaced with phase-to-phase voltages (i.e., VAB, VBC, and VCA).
