Table 9 LCD Error Messages
LCD Description Action Cause
RESET Reset occurred due to command or power up.
Always present after power up.
Warning Normal operation on power
up always sets RESET. RESET
is sent by HART communica-
tions. Use CLEAR ERR to
remove warning
LOW POWER Input current < 3.6 mA Takes the device to
low power
ACT ERR Positioner unable to position a valve normally Warning
AIR LOW Supply pressure is < 10 psi (.69 bar, 69 kPa).
Otherwise I/P pressure is below 0.8 psi (.05
bar, 5.5 kPa)
Warning Mechanical or pneumatic
problem
POS ERR The position error exceeds configured limit
for more than configured time
Warning after T1
and Failsafe
Pneumatic/ mechanical,
configuration, loose magnet
KEYBOARD LCD/Button Failure Warning Damaged buttons or LCD
electronics
MARGN PWR Input signal is insufficient to proceed
CALIB ERR Calibrate failed Warning Invalid values for current
calibration and input range
by HART commands
STOP ERR Calibration error. Find STOPS was unsuccess-
ful.
Warning Configuration, calibration
TUNE ERR Auto tune failed Warning Mechanical or pneumatic
problem causes tuning
failure
STD DIAG A standard diagnostic procedure failed to
complete
Warning Pneumatic / mechanical,
configuration
EXT DIAG An extended diagnostic procedure failed to
complete
Warning Pneumatic / mechanical,
configuration
CMD STOP HART command aborted Warning Bad data range or data limi-
tation
BIAS ERR Position algorithm error in output bias Warning Pneumatic/ mechanical
