6 Commissioning
WARNING
Improper commissioning in hazardous areas
Device failure or danger of explosion in hazardous areas.
● Do not commission the device until it has been mounted completely and connected in accordance with the information
in Chapter "Technical specifications (Page 31)".
● Before commissioning take the effect on other devices in the system into account.
6.1 Prerequisites / default settings
● Supply electrical and pneumatic auxiliary power to the SIPART PS2 positioner. The top row of the display shows the
current sensor voltage (0 to 100 %), while the "NOINI" info flashes in the bottom row. The pneumatic drive does not
move.
● Preset for rotary actuators:
While the valve or flaps are closed, align the North pole of the magnet with the cable; "N" in position
Mounting to the rotary actuator (Page 24)".
● Linear actuators with a stroke range up to 14 mm do not need to be preset.
● Preset for linear actuators with a stroke range > 14 mm (0.55 inch):
The magnet for the assembly kit for linear actuators > 14 mm (0.55 inch) is fixed. The factory default alignment of the
magnet is permanent.
● Monitor the display of the positioner while adjusting the actuator to its mechanical stops by means of
positioner. Verify that the displayed values never exceed the range from P2.0 to P98.0.
Note
This condition cannot be met with slipping flaps or actuators that exceed the mechanical actuation limits.
● If the display shows an inverted control direction, reset parameter "YDir" to "FALL", or turn the magnet by 180° (not
available for version 6DR4004-.NN30).
6.2 Initialization of rotary actuators
Procedure
1. For rotary actuators operating in standard control direction, set parameter "1.YFCT" to "ncSt", or to "-ncSt" in case of
inverse control direction.
2. Launch initialization as usual with "INITA".
6.3 Initializing linear drives with a stroke range up to 14 mm (0.55 inch)
Prerequisites
1. Set the "1.YFCT" parameter of the positioner to "ncSL".
2. Launch initialization as usual with "INITA".
6.4 Initializing linear drives with a stroke range > 14 mm (0.55 inch)
Note
Parameter value "ncSLL" is only available for device series 6DR5... with firmware version > C4. Set the value to 90° on
devices of the 6DR5... series with firmware version < C5 (YAGL). This setting is also necessary for devices of the 6DR4...
series. Resultant non-linearity can be corrected by means of the programmable characteristic by setting the parameter value
from "SFCT" to "FrEE" and adapting the interpolation points.
