Quinny 65040-AB manual Compressor has Shut Down Emergency Stop Button WAS Pressed

Section VIII - Power$ync II™ Operation

Cautionary and Shutdown Displays

The Power$ync II™ controller constantly monitors the operating conditions of the compressor. It has the most extensive monitoring and reporting capability of any compressor control on the market. LED indicators on a system schematic identify the location of the problem and the four-line, forty-character display explains the nature of the problem.

If an inlet air filter element or a fluid filter element has an excessive differential pressure, a light on the schematic will indicate which element is in need of service and a message will be briefly displayed that describes the nature of the fault. The display will then revert to the original operating display and the LED will remain illuminated to draw attention to the condition. In this instance, one of the following message will be displayed:

NOTICE

THE AIR FILTER NEEDS SERVICING

PLEASE REPLACE AS SOON AS POSSIBLE CONTACT YOUR SERVICE REPRESENTATIVE

NOTICE

THE FLUID FILTER NEEDS SERVICING

PLEASE REPLACE AS SOON AS POSSIBLE CONTACT YOUR SERVICE REPRESENTATIVE

These maintenance warnings will not cause the compressor to shutdown. Proper filtration is key to the long service life of this compressor, however, and the dirty element should be changed as soon as possible. The fluid filter does not contain a bypass valve that might allow unfiltered fluid to bypass the element. Be aware that continued operation with a prolonged high differential pressure warning indication may lead to a

reduction in fluid flow to the gears and bearings. This reduction in flow may cause temperatures to rise, efficiencies to drop and reduced service life for the airend. Do not operate the compressor for extended periods of time with dirty and plugged filtration. Use only Genuine Quincy Compressor filter elements for replacement.

Conditions that would result in unsafe operation will cause the Power$ync II™ controller to shutdown the compressor or alert the operator to shut the unit down. The following messages will be displayed when the controller detects a problem that would result in an unsafe operating condition:

**********CAUTION**********

COMPRESSOR HAS SHUT DOWN

EMERGENCY STOP BUTTON WAS PRESSED

If a condition exists at the compressor or in the compressed air system that requires that the compressor be stopped immediately, the red, mushroom-shaped Emergency Stop button can be pushed and the starter will immediately disengage. The Emergency Stop button will remain depressed until it is physically released. When the Power$ync II™ controller detects that this button has been pressed, it displays the message above to alert others that the Emergency Stop button was pressed. Do not attempt to restart the compressor until it has been determined who pushed the button and why. To clear the message, press ENTER. To restart the compressor, reset the Emergency Stop button and press the green Start button. Refer to the trouble shooting section for other causes.
