Sel SEL-421 - HIS CA and HIS RA Commands; ID Command

R.9.24
SEL-421 Relay Reference Manual Date Code 20111215
ASCII Command Reference
Description of Commands
If you issue the HIS CA and HIS RA commands, the relay prompts, Are you
sure (Y/N)?
If you answer Y <Enter>, the relay clears all history data and
event reports. The relay resets the event report number to 10000.
ID
Use the ID command to extract relay identification codes.
Each line of the ID command report contains an identification code and a line
checksum. The relay presents these codes in the following order:
FID: the Firmware Identification string
BFID: the Boot Firmware Identification string
CID: the checksum of the firmware
DEVID: the ID string as stored in the relay settings of the IED
DEVCODE: a unique Device Code (for Modus identification purposes)
PARTNO: the Part Number
CONFIG: abcdef.
The designator positions indicate a specific relay configuration:
“a” represents the nominal frequency; where 0 = N/A, 1 = 60 Hz, and
2= 50 Hz.
“b” represents the phase rotation; where 0 = N/A, 1 = ABC, and 2 =
ACB.
“c” represents the phase input current scaling; where 0 = N/A, 1 = 5 A,
and 2 = 1 A.
“d” represents the neutral input current scaling; where 0 = N/A, 1 = 5
A, 2 = 1 A, and 3 = SEF.
“e” represents the voltage input connection; where 0 = N/A, 1 = Delta,
and 2 = Wye.
“f” represents the current input connection; where 0 = N/A, 1 = Delta,
and 2 = Wye.
