Start-up
12. START-UP
12.1. Safety instructions
DANGER!
Danger – high pressure!
There is a serious risk of injury when reaching into the equipment.
• Before dismounting pneumatic lines and valves, turn off the pressure and vent the lines.
WARNING!
Risk of injury from improper operation!
Improper operation may result in injuries as well as damage to the device and the area around it.
• Before start-up, ensure that the operating personnel are familiar with and completely understand the contents
of the operating instructions.
• Observe the safety instructions and intended use.
• Only adequately trained personnel may operate the equipment/the device.
12.2. Specifying the standard settings
The basic settings of the positioner are implemented at the factory.
To adjust the positioner to local conditions, the X.TUNE function must be run following installation.
12.2.1. Running the automatic adjustment X.TUNE
WARNING!
Danger due to the valve position changing when the X.TUNE function is running!
When the X.TUNE is running under operating pressure, there is an acute risk of injury.
• Never run X.TUNE while a process is running!
• Take appropriate measures to prevent the equipment from being accidentally actuated!
NOTE!
Avoid maladjustment of the controller due to an incorrect pilot pressure or applied operating medium
pressure!
• Run X.TUNE whenever the pilot pressure (= pneumatic auxiliary energy) is available during subsequent
operation.
• Run the X.TUNE function preferably without operating medium pressure to exclude interference caused by
flow forces.
To run X.TUNE, the positioner must be in the AUTOMATIC operating status (DIP switch 4 = OFF).
