DC offset voltages in millivolts for the analog channels (IA,
IB, IC, VA, VB, VC) and master offset (MOF). F (Failure)
or W (Warning) following value in Status Displayed column
indicates an out-of-tolerance condition. Only MOF will
show a failure condition.

Power supply output voltages. W (Warning) or F (Failure)
following value indicates out-of-tolerance condition.
TEMP 26.1 Temperature inside the relay in degrees centigrade. W
(Warning) or F (Failure) following value indicates out-of-
tolerance condition.
RAM OK IC socket number in place of OK indicates failure.
ROM OK IC socket number in place of OK indicates failure.
A/D OK A self-test checks that all analog-to-digital conversion
processes complete each sample period.
CR_RAM OK Critical RAM contents (Global, Group, and Calibration
settings) are checked against their image in EEPROM. If
normal, OK is displayed. If not, GLOBAL, LOGIC n,
GROUP n, CAL, or CODE indicates failed area.
EEPROM OK Checksums of GLOBAL, GROUP, and CAL setting in
EEPROM are checked. If agrees with initial checksum, OK
is displayed. If not, GLOBAL, LOGIC n, GROUP n, CAL,
CODE indicates failed area.
SETTINGS OK Settings self-test checks status of Group, Global, Logic, and
Calibration valid settings, and Group LOGVAL settings. If
any setting is set to NO, relay protection is disabled and
GROUP, LOGIC, CAL, or GLOBAL indicates invalid
settings class. Otherwise, OK is displayed.
