Start-up and conguration
1. Turn untilCode1appears.
2. Press , the code number 1 and icon blink.
3. Turn to build up pressure in the positioner to move the valve slightly past the block-
ing position.
4. Press to cancel the mechanical blocking.
5. Turn untilCode0appears.
6. Press , the code number 0 blinks.
7. Turn until AUtO appears.
8. Press toconrm.Thepositionerswitchestoautomaticmode.Thecurrentvalveposi-
tionisindicatedin%.
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 the
'Operation' section.
7.6 Setting other parameters
AllcodesandtheirmeaninganddefaultsettingsarelistedinthecodelistinAnnexA.
CodeswhicharemarkedwithanasteriskmustbeenabledwithCode3beforetheassociat-
edparameterscanbeconguredasdescribedbelow.
