Section 12 • Configuration Screen
Overview
The configuration screen is where most of the
MicroVission features are enabled and configured. The
initial setup of the MicroVission will generally start here,
see Figure 12-1. Based on what is selected, different por-
tions of the MicroVission will be available to the operator.

Units

This section sets how values will be represented through-
out the MicroVission program.
Temp. Units
• Drop-down box to select the temperature units
from "Fahrenheit" and "Celsius". Once selected, all
screen temperatures will be displayed in the select-
ed units.
Press. Units
• Drop-down box to select the pressure units from
"Psig", "Bar" and "Kpa". Once selected, all screen
pressures will be displayed in the selected units.
Run Hours
• Offers the ability to change the compressor run
hours. This is typically used when replacing an older
micro controller on an existing compressor with a
new MicroVission.

No. of Cylinders
• The operator should set appropriate setting as per
the compressor connected. This setting informs the
control program to properly process the number of
analog channels for your compressor. For instance, if
12 or 16 cylinders is selected, then the control pro-
gram processes a second discharge pressure safety
and second discharge temperature safety. Disch
2 Press and Disch 2 Temp selection is allowed only
when No. of Cylinders configured is 12 or 16. User
can select one of the Auxiliary Analog Inputs for
Disch 2 Press and Disch 2 Temp.
When 12/16 cylinder is configured, Auxiliary Analog
Input selection for Disch 2 Press and Disch 2 Temp
combo box is mandatory.
No. of Unloaders
• The operator should set appropriate setting as per
the compressor connected. This setting informs the
control program to control unloader digital outputs
which in turn modulates the capacity of compres-
sor in steps. Each setting option displays the num-
ber of unloaders and the unload percentage steps
for the compressor. This setting is based on "No. of
Cylinders". For more information about Unloaders,
see Appendix: Unloaders.
