6 Commissioning
Note
The electrical power supply and supply air pressure data
indicated on the name plate must be complied with during
commissioning.
CAUTION
Risk of injury due to incorrect parameter values!
Incorrect parameter values can cause the valve to move
unexpectedly. This can lead to process failures and result in
injuries.
•
Before recommissioning a positioner that was previously
in use at another location, always reset the device to its
factory settings.
•
Never start automatic adjustment before restoring the
factory settings!
Note
Please observe the information in Operation on page 32 to
operate the device!
Commissioning the positioner:
1. Open the pneumatic power supply.
2. Power-up the electric power supply and feed in the setpoint
signal 4 to 20 mA.
3. Checking mechanical mounting:
•
Press and hold MODE; in addition, press or until
operating mode 1.3 (manual adjustment in the measuring
range) is displayed. Release MODE.
•
Press or to move the actuator into the mechanical
end position; check the end positions; rotational angle is
displayed in degrees; for high-speed mode, press or
simultaneously.
