4.2 CONTROL
SYSTEM:
The control system is designed for two modes of operation:
1) Manual start / automatic stop
2) Auto start / stop based on both suction and discharge pressure
The suction and discharge pressure switches have a "cut in" setting for starting and a "cut out" setting
for stopping. The deadband of each switch is adjustable. See instructions in appendix for adjustments.
In the event of an emergency an E-Stop button is provided. The E-Stop will disconnect all power to the
control box. The E-Stop has a mechanical Push-Pull latch. Pushing the button will stop all operation. To
continue operation pull the E-Stop button to reengage circuit control.
WARNING
If the unit is in AUTO mode when the E-Stop button is pulled the unit will automatically restart. It is
recommended to place the HOA Switch in HAND or OFF mode prior to pulling the E-Stop button.
An HOA (HAND/OFF/AUTO) switch is provided on the control panel which allows operator choice of
modes.
Details of the two operating modes are as follows:
