3. Enter the The Radio Power Status, which indicates the current status
of the Power Control function of ON, OFF, or RBX. The Active Zone
indicates which zone is currently activated for determining the Start
Time, On Time, and Off Time. Some of the On Time is also used by
the radio during power-up initialization of the receiver, causing part of
the On Time to be unavailable for receiving requests.
4. Select Radio Power Control Enabled to activate the Radio Power
Control function.
5. Use the radio buttons to select Seconds and Minutes. In Seconds
mode, the time base for the timers is in 0.1 second increments,
primarily used with radios. In Minutes mode, the time base for the
timers is in one-minute increments, primarily used with cellular
telephones.
6. Enter the Zone parameters to indicate when Radio Power Control is
active/inactive.
• Start Time that the respective Zone begins, in hours and minutes
(HHMM). Time is expressed in local time, 24-hour clock. For
example: “1500” under Zone 2 means that the associated On
Time and Off Time are used beginning at 3:00 p.m.
• On Time during a power cycle when the output is in the ON state.
• Off Time during a power cycle that the output is in the OFF state.
7. Enter the Hold Time that the output remains ON after detection of
communications activity (in seconds, unless the Minutes mode has
been enabled). This value applies to all Zones. When
communications occur during the On Time, the On Time is extended
by the Hold Time.
8. Enter the Low Battery Deadband. The Low Battery Deadband value
is added to the Low Battery Shutoff to determine when the Radio
Power Control function is enabled and allows the DO to turn ON as
needed.
9. Enter a Low Battery Shutoff value that specifies the voltage at which
Power Control is automatically disabled. The voltage being sensed is
the System AI Battery Input voltage (0-1). The Low Battery Shutoff
parameter allows power cycling to be automatically disabled
whenever the input voltage to the 3095FC falls below the specified
threshold. The default value is 11 Volts.
10. Select the Power Timer, which counts down the amount of time (On
Time, Off Time, or Hold Time) that the Radio Control is currently
using. The value is the number of seconds remaining.
11. Select which DO point the signal will send along.
12. Enter the On Counter, which indicates the cumulative time that the
Power Control has been in the ON state. The Off Counter value
indicates the cumulative time that the Power Control has been in the
OFF state.
