4. Historical Master Error Register
4.1 N/A - $80 / 1XXXXXXX
THIS ERROR SHOULD NOT OCCUR. IF IT DOES REPLACE THE MASTER
OR MCU PCB.
4.2 N/A - $40 / X1XXXXXX
THIS ERROR SHOULD NOT OCCUR. IF IT DOES REPLACE THE MASTER
OR MCU PCB.
4.3 N/A - $20 / XX1XXXXX
THIS ERROR SHOULD NOT OCCUR. IF IT DOES REPLACE THE MASTER
OR MCU PCB.
N/A - $10 / XXX1XXXX
THIS ERROR SHOULD NOT OCCUR. IF IT DOES REPLACE THE MASTER
OR MCU PCB.
4.5 Pressure Transducer Error - $08 / XXXX1XXX
4.5.1 Description:
This error occurs if the Slave consistently (100 times) reports to the Master pressure
transducer values that exceed the maximum or minimum limits determined at the
time of design. An error will only be registered during the auto-zeroing of the
pressure transducer before a pressure up occurs.
4.5.2 Suggestions:
Test the pressure transducer section of the circuitry on the MCU PCB per the
hardware specification document.
4.6 EEPROM Checksum Error - $04 / XXXXX1XX
4.6.1 Description:
This error is the result of a corrupted value in the EEPROM. Not all of the
EEPROM is tested only the locations that contain calibration information. This is
because these locations should never change once the unit has been calibrated. Other
locations will change each time a user saves test data or actuation counters are
updated.
4.6.2 Suggestions:
Clear the error registers, re-calibrate the unit, perform an EEPROM test, power
down, and verify that the problem no longer exists. Replace EEPROM and/or MCU
PCB.
