This diagnostic screen is used to analyze the analog and
Digital inputs of the Motor Monitoring Board. The in-
puts are identified by terminal strip and terminal num-
ber. Also, serial communications error statistics are
displayed here. See the description of this board in
of this manual.
ANALOG INPUTS
The voltage level of each Analog Input (as measured
to ground) at the indicated input terminals is displayed
as X.XX VDC.

VIBRATION INPUTS
Gain -
Displays the value programmed for the Vibra-
tion Input Gain setpoint for the accelerometer inputs.
The gain can be changed from this screen using the
CHANGE GAIN key. See below.
Vibration -
The accelerometer vibration level input
(as measured to ground) at the indicated terminals is
displayed as XX.X. The vibration values are not in any
particular units of measure. They are relative values.
The larger the number, the greater the magnitude of
vibration.
