FIGURE 3--9 ANALOG VOLTAGE INPUTS SCREEN
This screen includes analog inputs associated with internal references with scaled values in volts.
The data values displayed are updated at 8 Hz. Also included is the unit of measure and an
indication as to whether the signal is valid.
ITEM DESCRIPTION
Adj. Pot Adjustment potentiometer accessible through the
FCC front panel, used to make installation
adjustments. This value is from a single turn,
270--degree rotation potentiometer with an
adjustment range of 0 to 5V. Validity based on
internal Analog Valid.
Photocell Photocell embedded in FCC front panel used to
automatically adjust intensity of gas--discharge
display based on ambient light level. Displayed
value will be near 0V when photocell is covered and
4.5V when photocell is exposed to bright light.
Resolution of display value is 4.9mV per bit. Validity
based on internal Analog Valid.
