Powering the Device
Apply power to the XFC
G5
or XRC
G5
by making the correct connections for the power mode chosen.
The XFC
G5
and XRC
G5
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.
The XFC
G5
and XRC
G5
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
G5
or XRC
G5
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 and restart
configuration.
The XFC
G5
and XRC
G5
power-on sequence is initiated as soon as power is connected. The LCD displays
the following information as the controller completes the startup:

IMPORTANT NOTE:
If the LCD fails to display the startup sequence, try adjusting the contrast
If adjusting the contrast does not
show any items on the LCD, see section
Operating in battery power mode requires a 12-volt sealed lead acid (SLA) battery and a charger to
recharge the battery. This mode requires connection of the battery and the charger. The battery and
charger must be installed. See section
. Adapt these instructions for
alternate installations.
