1. The process value exceeded the setpoint value too
quickly for the Auto Tune calculations to complete.
a) Lower the process value further before
re-attempting Auto Tune (page 36).
b) If not used, select out2 =3 or 5 then
re-attempt Auto Tune (page 36).
c) Reduce the o1uL percentage of output
value in steps of 10% and re-attempt Auto
Tune until Er56 doesn't appear (page 36).
1. The process response samples are checked to
detect erroneous values that might be caused
by noise on the sensor input. If noise is detected
the Auto Tune will abort. Inspect the instrument
and the sensor for proper installation. Re-attempt
the Auto Tune (page 36).
1. If the AUTO TUNE key is pressed while the Auto
Tune feature is active the Auto Tune will abort.
Re-attempt the Auto Tune (page 36).
1. If a non-Auto Tune Error condition occurs while the
Auto Tune is active, the Auto Tune will abort.
Clear the error condition and re-try the Auto Tune
(page 36).
1. If the instrument power goes off while the Auto During
Tune is active it will cause the Auto Tune to abort.
Re-attempt the Auto Tune (page 36).
1. Tried to communicate while unit was in a non-
control mode.
1. The unit received a request before proper amount
of time has elapsed since last request.
1. Data received not valid, possible corruption on
the commlink. Possible noise.
1. Improper parity selection on the transmitting
terminal.
2. Incorrect baud rate.
3. Noise.
