Operation
60 Quincy Compressor
®
- QSD™
During the initial power-up diagnostic routine, the
controller checks for correct data concerning the
compressor setup parameters. As discussed earlier, the
compressor will be prevented from running if there is an
error in that data. While the compressor is operating, the
controller continues to check the validity of that data.
Should there be a problem with the setup data while the
machine is operating, the following message will be
displayed:
FLUID PRESSURE__________
COMPRESSOR HAS SHUT DOWN
**NOTICE** U19 MEMORY FAILURE
REFER TO YOUR SERVICE MANUAL
This condition will prevent the compressor from
operating. Attempt to correct the situation by
turning power off to the compressor and then
reapplying power. This will begin the diagnostic
program again. It may be possible to run the
compressor on the default setup values, if the
original setup data is not usable. Call your service
representative if this does not correct the problem.
Your service representative can determine whether
correct setup information can be reentered into
the controller or the memory board needs to be
replaced. The compressor can be operated in
Back-up Mode.
In the Network Mode, the controller continually checks
for other errors. These include:
NOTICE
SEQUENCE DATA ERROR
PRESS F1 TO CLEAR
NOTICE
SCHEDULE DATA ERROR
PRESS F1 TO CLEAR
These two messages may appear if the back-up
battery on the control board fails or is replaced.
Press F1 to clear the display, then access the
schedule and/or sequence menus and reenter that
data. See Compressor Settings and Maintenance
Displays for instruction on this procedure. Time
and date will also have to be reset.
NOTICE
THIS COMPRESSOR MACHINE ID
IS ALREADY IN USE
PRESS ENTER TO CONTINUE
If the main memory board of the controller has to
be replaced for some reason and the machine is
on a network, the new board may have a default
machine ID that conflicts with another machine
on the network. Press ENTER to clear this screen
and then reassign a new machine ID to this unit.
