To enable a high-accuracy external time source, connect an IRIG-B clock to
the relay. For a discussion of the IRIG timing modes in the relay see
Configuring High-Accuracy Timekeeping on page P.13.1. See TIME Input
Connections on page P.2.36 for more information on connecting time source
inputs.
Relay Status
The relay performs continuous hardware and software self-checking. If any
vital system in the relay approaches a failure condition, the relay issues a
status warning. If the relay detects a failure, the relay displays the status
failure
RELAY STATUS screen immediately on the LCD.
For both warning and failure conditions, the relay shows the error message for
the system or function that caused the warning or failure condition. You can
access the
RELAY STATUS screen via the MAIN MENU. The RELAY STATUS screen
shows the firmware identification number (FID), serial number, whether the
relay is enabled, and any status warnings.
Figure 7.38 shows examples of a normal
RELAY STATUS screen, a status
warning
RELAY STATUS screen, and a status failure RELAY STATUS screen. For
more information on status warning and status failure messages, see Relay
Self-Tests on page P.11.38.
