9.4 Initialization messages
Not defined
The device has not been initialized, or a coldstart was carried out.
Automatic reset after confirmation.
Aborted
The initialization routine was aborted by the user.
Automatic reset after acknowledgement.
If the device was already successfully initialized and no coldstart was performed, control
operation restarts.
Defective mechanics/pneumatic section
The initialization routine recognizes a constant change or no change of the value measured
for travel/angle. Initialization is aborted.
Possible sources of error:
– Supply pressure too low/not stable
– Air capacity too low
– Improper mechanical attachment
– Lever not properly hung
– For NAMUR attachment: lever not correctly secured to the shaft of the adapter housing
– Connecting cable between logic and displacement sensor board disengaged.
Timeout
The initialization routine cannot move the valve to end position within 240 seconds.
Initialization is aborted.
Possible sources of error:
– Large difference between static and sliding friction at the control valve (oscillation)
is generated as an individual message
– Supply pressure unstable
– Air capacity too low.
Incorrect selection of rated travel or transmission
The maximum determined travel which is read out as per cent value of the rated
travel/angle is smaller than the selected rated travel/angle. This message is only generated
in initialization mode "related to nominal range"; warning, initialization is not aborted.
