WARNING
Water in compressed air line
Device damage and possibly loss of type of protection. The factory setting for the purging air selector is "IN". In the "IN"
position, water from the compressed air line may enter the device from the pneumatics during initial commissioning.
● Before commissioning, make sure that no water is present in the compressed air line.
If you cannot be sure that there is no water in the compressed air line:
● Set the purging air selector to "OUT". In this way, you prevent water from the compressed air line from penetrating the
device.
● Only set the purging air selector to "IN" again when all water has been discharged from the compressed air line.
CAUTION
Loss of degree of protection
Damage to device if the enclosure is open or not properly closed. The degree of protection specified on the nameplate or in
Chapter "Technical data (Page 35)" is no longer guaranteed.
● Make sure that the device is securely closed.
WARNING
Commissioning and operation with pending error
If an error message appears, correct operation in the process is no longer guaranteed.
● Check the gravity of the error
● Correct the error
● If the error still exists:
– Take the device out of operation.
– Prevent renewed commissioning.
5.1.1 Safety notes for operation with natural gas
See detailed operating instructions for information and safety notes on operation with natural gas as an actuator medium.
5.2 Overview
Note
● During the initialization process, the operating pressure must be at least one bar more than that required to close or open
the valve. However, the operating pressure should not be greater than the maximum permissible operating pressure for
the actuator.
● The transmission ratio selector can be set only when the positioner is open. Therefore, check this setting before closing
the enclosure.
General information about commissioning
After installing the positioner on a pneumatic actuator, you must supply electric and pneumatic auxiliary power to it.
The positioner is in the "P manual mode" before initialization. At the same time, "NOINI" blinks in the lower line of the
display.
Adjust the positioner as per the respective actuator with the help of the initialization process and by setting the parameters. If
required, use the "PRST" parameter to cancel the adjustment of the positioner on the actuator. The positioner is again in the
"P manual mode" after this process.
