STA Command Row and Column Definitions
FID FID is the firmware identifier string. It identifies the firmware revision.
CID CID is the recloser control firmware checksum identifier.
BCBFID BCBFID is the firmware checksum of the battery charger board firmware.
W (Warning) or F (Failure) is appended to the values to indicate an out-of-tolerance condition.
OS OS = Offset; displays measured dc offset voltages in millivolts for the current and
voltage channels. The MOF (master) status is the dc offset in the A/D circuit
when a grounded input is selected.
PS PS = Power Supply; displays power supply output voltages in dc volts.
TEMP Displays the internal relay module temperature in degrees Celsius.
RAM, ROM, CR_RAM (critical RAM), and EEPROM
These results verify the relay module memory component status. The columns
display OK if memory is functioning properly, or FAIL if the memory area has
failed.
A/D Analog to Digital convert status.
IO_BRD Extra I/O board status.
SF6 Displays SF6 gas pressure in atmospheres.
BATT Displays status and mode of the battery charger board:
MODE Mode that battery charger is in:
• CHARGE Battery is charged to 90% or more, charging at low charge rate.
• HICHRG Battery is charged to less than 90%, charging at high charge
rate.
• DISCHG Battery is discharging but is charged to greater than SLPCAP
setting.
• DISTST Battery discharge test at 1 Amp for 6 seconds duration.
• NOBATT Battery is not present.
• FAIL Battery monitor/charger has failed or communications with the
battery monitor/charger are temporarily interrupted.
%CAP The %CAP column shows battery charge level in percent battery capacity
independent of temperature.
HRS_LFT The HRS_LFT column shows the amount of time left until the control is put into
sleep mode in hours and minutes when in discharge mode. If the control is in
charge or high charge mode, this column reads “XX:XX”.
5V_PSBC Voltage level in Vdc of the 5 volt supply on the battery charger board.
12V_AUX Voltage level in Vdc of the 12 volt auxilliary port supply.
VBAT Voltage level of the 24 volt battery in Vdc.
IBAT Charge or discharge current in milliamps dc. If current is discharging, value is
preceded by a minus sign “-”; if current is charging, value is displayed with no
preceding character.
