Stopping The Compressor - Normal Operation; Stopping The Compressor - Emergency Operation; Electronic Control Operations - Quincy QSF Series Instruction Manual

Stopping the Compressor - Normal Operation

•
Close the service valve to the plant air distribution system.
•
Allow the pressure to build within the reservoir and the compressor to fully unload.
•
Press the stop button on the keypad.
NOTE:
It is always a good practice to close the service valve when the compressor is not being used. It will
prevent the system's air pressure from leaking back into the reservoir if the check valve leaks or fails.
Stopping the Compressor - Emergency
•
Press the emergency stop button or remove the power at the main disconnect switch or panel.

Electronic Control Operations

This manual describes the operation of the microprocessor control on the QSF Air Compressor.
The decal at the right shows the control layout for
the electronic control panel.
The primary controls are on the right hand side of
the panel, with the selected item being displayed
on the LED digits in the top window.
The LED lamps in a vertical row, show the selected
display parameter and/or any alarm conditions.
On applying system power, the LED status lights
will blink and the numeric display will show the
version number of the software code installed.
The system will be ready to run, with the 'POWER'
lamp on (showing that the control board has
power) and the 'SYSTEM PRESSURE' LED will be
lit, showing the pressure on the numeric display.
NOTE: A flashing '----' on the digit display, accompanied with an LED on the left, will signify a faulty
sensor; either the pressure transducer or the temperature probe.
A FAST blinking LED indicates that the labeled function has been tripped; an over-pressure condition or
motor overload or Reservoir High Air Temperature (HAT) trip.
A SLOW blinking LED indicates that a Differential Pressure (D.P) switch has been tripped. A STEADY
LED indicates a service timeout, along with a message blinking on the display. The controller is
programmed with recommended service intervals on the FLUID FILTER and the AIR filter. These filters
should be checked and serviced when convenient.
