Description
Not defined
The device has not been initialized or a cold start was performed. Automatically reset after confirmation.
Aborted
The initialization routine was canceled by the user.
Automatically reset after confirmation.
If the device has already been successfully initialized and no cold start was performed, the device returns to control
operation.
Error in mechanics/pneumatics
The initialization routine detects no or a constant 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 linked
– For NAMUR attachment: lever not properly attached to the shaft of the adapter housing
– Connecting cable between logic and displacement sensor board disconnected.
Timeout
The initialization routine cannot move the valve to the final position within 240 seconds. Initialization is aborted.
Possible sources of error:
– Large difference between static and sliding friction at the valve (oscillation) is generated as an individual message
– Supply pressure unstable
– Air capacity too low
Incorrect selection of rated travel or transmission
The determined maximum travel, given as per-cent value of the rated travel/nominal angle, is smaller than the selected
rated travel/nominal angle. Warning, initialization is not aborted.
Possible sources of error:
– Incorrect mechanical attachment
– Incorrect transmission entered
– For NAMUR attachment: wrong pin position entered
– Valve is blocked
– Supply air pressure is too low. The supply air pressure should be at least 0.4 bar above the upper spring range
(see section 3.1.2).
