2. Tighten the cable gland
3. Terminate the four-pole NCS cable

4. Place the cable clamp

5. Use the screw to bond the cable shielding lug
6. Grounding:
The rear steel panel of the NCS is inevitably bonded to ground potential of the system by mounting the console. This
ground connection is only functional if there is a low-impedance connection to ground potential of the system. Ensure this
state by measuring ground resistance. If necessary, ensure proper grounding by means of an additional cable from the
NCS to ground potential.
For installation and connecting instructions for the EMC filter module, and information on which cable gland should be used,
refer to the positioner operating instructions, chapter "Installing/Mounting" and to chapter "Connecting".
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 15)".
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 actuator does not
move.
● Preset for part-turn actuators:
While the valve or flaps are closed, align the North pole of the magnet with the cable; "N" in position
Mounting on part-turn actuator with magnet holder made of glass fiber reinforced polyester (left graphic) or anodized
aluminum (right graphic) (Page 8)".
● 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 linear 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-.N.30).
6.2 Initialization of part-turn actuators
Procedure
1. For part-turn 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".
