Sub data:
Description: The transducers calibration values are stored in two separate E2-
potentiometer memories on PC 1750 Transducer and on PC 1748/PC 1797 Fresh gas
flow. All calibration values is also stored on PC 1672 Control panel.
When the system is powered-up, the calibration values are compared to check that
they match each other. If not, a diagnostic log is written.
What to do:
1.
Perform a Calibration and a PuC. Restart the KION workstation and check
that the diagnostic log is not reproduced.
2.
Replace PC 1750 Transducer if a digit is present in A, C or D.
3.
Replace PC 1748/PC 1797 Fresh gas flow if a digit is present in B.
4.
Replace the PC 1672 Control panel
5.
Replace PC 1730 Control.
Fault: Stored calibration values for the pressure transducers are not correct at system
start-up (Off to Standby).
Description: The transducers calibration values are stored in two separate E2-
potentiometer memories on PC 1750 Transducer.
The E2-potentiometer contains both a non-volatile memory and a volatile memory.
At start-up of the system, data in the non-volatile memory (REG0) is transferred to the
volatile memory (WCR) for each transducer.
After the transfer, a comparison test is made between the non-volatile and the volatile
memory to see that the transfer completed successfully. If comparison fails, a
diagnostic log is written.
What to do:
1.
Perform a Calibration and a PuC. Restart the KION workstation and check
that the diagnostic log is not reproduced.
2.
Replace PC 1750 Transducer if a digit is present in B, C or D.
3.
Replace PC 1737 Measuring.
Fault: Stored calibration values for the pressure transducers are not correct at system
start-up (Off to Standby).
Note! This diagnostic log may appear before calibration when upgrading the MEA-
PROM.
