Wrong mounting kit
▶ If no initial spring tension can be felt, it may be the case
that the wrong mounting kit with too short an operating
bush has been used.
▶ If the spring locks and the positioner cannot be correctly
mounted on the valve, it may be the case that the wrong
mounting kit with too long an operating bush has been
used or that a required adapter has not been used.
▶ In both cases, check the mounting kit parts and that they
are being used correctly and in their entirety.
