Powering the device
Apply power to the XRC or XFC by making the correct connections for the
power mode chosen. The XFC and XRC support two power modes:
Battery mode: The primary power source is a 12 volt battery with a
charger.
External power mode: The primary power source is an external power
supply.
Super capacitor charging at boot time
The XFC and XRC design includes a super capacitor (Super CAP) that serves
as a short-term power reservoir. Allow 2 minutes to charge the super CAP
the first time you connect the unit to power. The Super CAP must recharge
if the XFC or XRC is powered off for several hours. After the capacitor is
fully charged, the boot time is considerably less.
IMPORTANT NOTE:
In the event of a loss of power or reset, the
charged super capacitor prevents the supply voltage from
falling to zero for a short period of time (2.5 seconds). This
delay allows the system time to save all persistent data such as
trending, restart configuration, etc.
Power-on sequence
The XFC and XRC power-on sequence is initiated as soon as power is
connected. LCD displays the following information as the controller
completes the startup:
