Detected problems that will not result in an unsafe
operating condition but should be corrected as soon as
possible include:
NOTICE
DEADBAND DATA ERROR
PRESS F1 TO CLEAR
In Network Mode, an unload pressure setting and
a reload pressure setting are required. If the
controller cannot find pressure settings that are
within a reasonable range during the diagnostic
program, it will display this message. To correct
the problem, go to Network Menu 1 and select
SETUP NETWORK PRESSURES. Confirm the
pressure ranges and press ENTER . The display
will then change to NETWORK UNLOAD/LOAD
PRESSURE SETUP. The current network unload
pressure setting will be flashing. Use the UP and
DOWN arrow keys (located to the right of the
display window) to select the setting. Press F1 to
change the setting and press ENTER to accept
the settings. This warning is most likely to occur
at initial start-up after a circuit board change, chip
change, software upgrade or if the EEPROM chip
on the circuit board fails (U19). Entering load
and unload pressure settings will correct the
problem unless the EE chip has failed.
NOTICE
U19 DATA CHECKSUM ERROR
PRESS F2 TO UPDATE
Power$ync II
™
uses a checksum function to
confirm the information in the setup memory. If
the information in the memory has changed, the
checksum number will not be the same. This
message indicates that the diagnostic program has
detected such a change. There are default values
for this information that will allow the Power$ync
II
™
computer to operate the compressor if it cannot
find the correct checksum number in the setup
information. Operation using the default checksum
may not be as efficient as operation would be with
all correct configuration information entered.
Press F2 to install the default checksum into the
computer memory and all subsequent restarts will
be completed using this default information. To
achieve the highest level of efficiency, it is
important that the Power$ync II
™
computer have
the correct configuration data. Your service
representative can enter that data and initialize
the system.
NOTICE
U19 DATA NOT INITIALIZED
PRESS F2 TO INITIALIZE
The Power$ync II
™
computer is programmed with
information concerning the configuration of the
machine onto which it is installed. This
information includes; motor horsepower, type of
cooling, type of starting, pressure ranges, etc.
Power$ync II
™
needs this information to provide
the most efficient operation. At start-up, the
computer confirms that all this information is in
its memory. It will display this message if it cannot
find the information in memory. There are default
values for this information that will allow the
Power$ync II
™
computer to operate the
compressor if it cannot find the information.
Operation using default values may not be as
efficient as operation would be with all
configuration information entered and initialized.
Press F2 to install the default information into
memory and all subsequent restarts will use the
default information. To achieve the highest level
of efficiency, it is important that the Power$ync
II
™
computer have the correct configuration data.
Your service representative can enter that data and
initialize the system.
