4. Front display initially displays the time as 12:00:00 and its software version.
5. Transmitter checks the position of the switches on the back of the Transmitter, and stores the settings in its memory.
6. Transmitter completes an initialization sequence with its time source. Its time source may be either a GPS Receiver, NTP, or
Repeater (Satellite) Transmitter.
Power failure
During a power failure, the Transmitter continues to track time with the last valid time signal that it received. Once the power had
been restored, the Transmitter begins to broadcast (even without a valid time signal) to the down-stream components. Once the
Transmitter has been powered on for a few hours, it's capable of keeping track of time off its internal backup power for up to
eight hours.
The system has a fail-safe design. If the failure of a system component or power loss to a component occurs, all down-stream
l
components continue normal operations using their own internal time base.
If after a specified period of time communication has not been restored, a visual indicator of a loss of communication appears
l
and remains until communication is restored. Loss of communication visual indicators: Transmitter LED flashing, flashing
colon on LED digital clocks/timers; stepping of second hand on analog clocks.
NOTE
Transmitter with an External Antenna: In the event of a facility wide power outage, a Transmitter with an External
Antenna will broadcast continuously for 8 hours upon the restoration of power, synchronizing all Primex devices
throughout the facility.
In the event power to a Transmitter is shut off and turned back on (power cycled) the Transmitter will broadcast
continuously for 8 hours. Power cycling the Transmitter can be used to set/reset system devices. It's not recommended
to power-cycle a Transmitter when it is in an error status - indicated when its red LED is flashing.
