Relay Enabled
=>
The relay latches all self-test warnings and failures in order to capture
transient out-of-tolerance conditions. To reset the self-test statuses, use the
STA C command from Access Level 2:
=>>STA C <Enter>
The relay responds:
Reboot the relay and clear status
Are you sure (Y/N) ?
Table 10.8 STA Command Row and Column Definitions
Row Definition
FID
FID is the firmware identifier string.
It identifies the firmware revision.
CID
CID is the firmware checksum identifier.
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 voltages in Vdc for the power supply outputs.
TEMP
Displays the internal relay temperature in degrees Celsius.
RAM, ROM,
CR_RAM
(critical
RAM), and
EEPROM
These tests verify that the relay memory components are
functional. The columns display
OK if memory is functioning prop-
erly; the columns display
FAIL if the memory area has failed.
A/D
Analog to Digital converter status.
IO_BRD
Extra I/O board status—model 0311C01x only; see Table 1. 1 and
Figure 2.8, Figure 2.9, Figure 2.11, and Figure 2.16. On models
without I/O boards, the I/O_BRD status is always okay.
W (Warning) or
F (Failure)
W or F is appended to the values to
indicate an out-of-tolerance condition.
