6-6 Electrical
6-6-1 Description and Objectives
This section is designed to give the operator an overview of the electrical
system that controls the OS/OA blending system. Since the OS/OA’s
control panel is a self- contained pluggable item, seldom will a
maintenance person be required to enter the control panel. For purposes
of understanding the system it is advisable that the maintenance
personnel be familiar with not only the internal workings of the control
panel, but also with the input and output signals to the OS/OA unit.
This section includes the following:
• Internal components of the control panel
• Input signal to the control panel
• Output signals from the control panel
6-6-2 Internal Components of the Control Panel
Note: See Section 12-2 for complete electrical schematics.
This section describes the internal components of the OS/OA blending
system control panel. It is not the intent of this section to completely
familiarize the reader with the details on industrial control panel
construction or standards, but simply to familiarize the reader with the
major components inside the OS/OA control panel.
The customer must supply 110/1/50 or 60 (or 220/1/50) via wires L1 &
L2 (N). Please insure that the earth ground connection is properly
connected to an established earth ground.
“Power on” is indicated by a lighted on/off switch.
