Operating the positioner
Start initialization:
Î
Press INIT key.
The operating mode is changed to automatic mode .
Since initialization has not been completed, the error code 76 (no emergency mode) and
possibly also error code 57 (control loop) may appear on the display. These alarms do not
influence the positioner’s readiness for operation.
Î
If the positioner shows a tendency to oscillate in automatic mode, the parameters K
P
and
T
V
must be slightly corrected. Proceed as follows:
–
Set T
V
(Code 18) to 4.
–
If the positioner still oscillates, the gain K
P
(Code 17) must be decreased until the posi -
tioner shows a stable behavior.
Zero point calibration
Î
Finally, if process operations allow it, the zero point must be calibrated according to sec-
tion 7.7.
7.6.6 Tuning the KP input filter
Changing the KP level (Code 17) affects the set point deviation. This effect can be compen -
sated for by tuning the input filter without having to re-initialize the positioner.
