SYSTEM CLOCK
This feature allows the user to set the relay internal
clock. The clock is used to time stamp system events
and oscillograph operations.
The clock is disabled when shipped from the
factory (indicated by “80” seconds appearing on
the clock) to preserve battery life. If the relay is to
be unpowered for an extended length of time, the
clock should be stopped (from Diagnostic Mode
or IPScom Figure 4-7). If the IRIG-B interface is
used, the hours, minutes, and seconds information
in the clock will be synchronized with IRIG-B time
information every hour.
The relay can accept a modulated IRIG-B
signal using the rear panel BNC connector, or a
demodulated TTL level signal using extra pins on
the rear panel COM2 RS-232 interface connector
(see Figure B-4 for COM2 pinout.) If the TTL signal
is to be used, then Jumper 5 will be required to be
positioned (see Section 5.5, Circuit Board Switches
and Jumpers).
