• Bit 0 – Currently in fail safe time out . No setpoint commands have been sent from the controlling system for the entire
time out period . The positioner only fail safes when it is on-line . So, communication from the host have ceased . Most
probable cause is that the host or FBM has been taken off-line or the connection has been broken .
DIAGNOSTIC STATUS
In general, an error bit raised here indicates a serious problem in the positioner and probably requires replacement .
Message
Explanation
Recommended Action
RAM
Error Writing positioner memory .
Replace failed item or positioner .
EEPROM
Error Writing positioner EEPROM .
Replace failed item or positioner .
ROM
Error Writing positioner ROM .
Replace failed item or positioner .
AD Converter
Converter function not controllable .
Replace failed item or positioner .
Actuator OOR
Position is not within permissible range (-5% . . . +105%) .
Check mechanics of actuator and valve .
Perform Endpoints Calibration .
Current Loop
I/P Motor
Connection of I/P converter to electronic board failed .
Replace failed item or positioner .
Potentiometer Connection of potentiometer to electronic board failed .
Replace failed item or positioner .

• Bit 6 – Potentiometer use has failed; the positioner no longer accurately controls the valve . (Fatal) .
• Bit 5 – Current loop to I/P-Motor broken . (Fatal) .
• Bit 4 – The actuator is out of range . Position is unreliable or not being properly controlled . (Fatal) .
• Bit 3 – Analog to Digital conversion won’t finish . (Fatal) .
• Bit 2 – Access to positioner read addressable memory (RAM) resulted in an error . If all the data in the configuration pages
looks correct, the positioner is probably still functional .
• Bit 1 – Access to positioner EEPROM resulted in an error . Positioner is incapable of storing configuration information or
saving data . (Non-fatal)
• Bit 0 – Access to positioner ROM resulted in an error . Positioner software is now unreliable . (Fatal) .
RAM Diagnostic Bit 0
Access to positioner read only memory resulted in an error . Positioner must be replaced because the software is no
longer reliable .
EEPROM Diagnostic Bit 1
Access to positioner EEPROM resulted in an error . Positioner is incapable of storing configuration or saving data . It will still run
until the next cycling of power, but should be replaced at the earliest opportunity .
ROM Diagnostic Bit 2
Access to positioner read addressable memory (RAM) resulted in an error . RAM is used to initialize data . If all the data in the
configuration pages looks correct, the positioner is probably still functional . It should be replaced at the earliest opportunity,
however .
