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.
