Quinny 65040-AB Deadband Data Error Press F1 to Clear, U19 Data Checksum Error Press F2 to Update

Section VIII - Power$ync II™ Operation

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.
