1.6 Product Electronics
This section describes the FB107 electronic components.
1.6.1 Real-Time Clock
The real-time clock provides the FB107 with the time of day, month,
year, and day of the week, as well as real-time stamping of the database
values. The real-time clock automatically switches to backup power when
the FB107 loses primary input power. Backup power for the real-time
clock is adequate for a period in excess of one-year with no power
applied to the FB107.
The internal super-cap provides backup for the data and the real-time
clock when the main power is not connected. The super-cap has a one-
year minimum backup life with the battery installed and no power applied
to the FB107.
Note
:
The real-time clock uses the super-cap to keep the current time
when you replace the lithium battery.
1.6.2 Diagnostic Monitoring
The electronics board has five diagnostic inputs incorporated into the
circuitry for monitoring system integrity. Access these analog inputs
using the I/O function of ROCLINK 800 software (
Configure > I/O ).

1.6.3 Automatic Self Tests
The FB107 becomes active when input power with the proper polarity
and startup voltage (typically set greater than 8.0 volts) is applied to the
