Automation and control elements
Automatic operation can be assigned via the switches
on the control panel of the operating or control air compressor. In this case,
the compressor will be started and stopped by a pressure switch mounted on the
compressor bleed line.
Separators (oil and water) have solenoid drain valves
that open and close automatically to return the oil separated to the compressor
or to remove condensed water. Also, the automatic opening and closing valves
allow the compressor to start or stop, reducing the load on the motor and
compressor drive.
PLC modules control and monitor the compressor during
its operation. Each PLC unit has a screen and various buttons that allow the
operator to connect to the PLC program. Press the ESC key to access the main
menu. Some program settings are adjustable. To adjust the parameter, in the
main menu, press the DOWN button to select the SET PARAM option and confirm
your selection with the OK button. Next, select the desired setting with the up
or down buttons. The selection is confirmed with the OK button. The values are
adjusted with the up and down, left and right buttons. The new value is
confirmed with the OK button. The initial value is saved by pressing the ESC
key. To return to the normal screen, press the ESC key twice. For more
information on other PLC menus and functions, refer to the manufacturer's
manual.
