Setting the Time and Date

BESTCOMSPlus Navigation Path: Metering Explorer, Status, Real Time Clock
HMI Navigation Path: Metering Explorer, Status, Real Time Clock
Time and date settings can be made through BESTCOMSPlus on the Real Time Clock screen (Figure
274) under the Status branch of the Metering Explorer. Settings can also be made through the front
panel.

IRIG Port

IRIG time code signal connections are located on the rear panel. When a valid time code signal is
detected at the port, it is used to synchronize the clock function. Note that the IRIG time code signal
received from older IRIG receivers does not contain year information. If this is the case, it will be
necessary to enter the date manually. Year information is stored in nonvolatile memory so that when
operating power is restored after an outage and the clock is re-synchronized the current year is restored.
When the clock rolls over to a new year, the year is automatically incremented in nonvolatile memory. An
alarm bit is included in the programmable alarm function for loss of IRIG signal. The alarm point monitors
for IRIG signal loss once a valid signal is detected at the IRIG port.
Connections
IRIG connections are located on a terminal block shared with the RS-485 and input power terminals.
Terminal designations and functions are shown in Table 115.
