Positioner Setup And Calibration - Siemens PS2 Installation And F.a.q

POSITIONER SET UP &
Positioner Set Up
NOTE: Refer to the positioner information sticker to confi rm that your Siemens
software version and HART protocol drivers are the version required for your
positioner. For more information contact Dyna-Flo Control Valves Services.
1 Attach positioner to actuator using mounting hardware. Refer to attached
schematic. Mounting Instructions (Pages 3 to 20).
2 Tube up positioner.
a Y1 port is output to diaphragm.
b PZ port is supply from regulator (Note: positioner requires very clean dry
air according to ISO/DIS 8573-1: Class 2, a better than normal fi lter is
required, we supply a 5 micron fi lter in the instrument supply regulator).
c Use a coalescing fi lter if liquids are present in the supply gas.
3 Remove the cover and attach a mA (milliamp) source. Class I Zone II
version has four screws around the outside of the cover, where Class I Zone I
Explosion Proof Model has a blue end cap that unscrews from the main body.
Refer to the SIPART PS2 Operation Instructions Latest Edition, for basic device
wiring schematics. A wiring diagram is included under the cover of the positioner.
a Terminal '3' is positive.
b Terminal '8' is negative.
4 Turn on mA source (set between 4 mA – 20 mA, it does not matter).
5 Set Transmission Ratio Selector, ensure it is fully engaged (all the way up or
down). On the Class I Zone II model, this is a square yellow vertical pin that is
in the middle of the positioner body (Figure 11B). If you have the Class I Zone I
explosion proof model, this is located inside the positioner in the same
location, but is a yellow tab that needs to be moved with a small screw driver
up or down. Refer to Figure 11B, Page 27. The sticker on the front shows the
"33" and "90" position.
a 90 (up) position for travel more than 1-1/4" and rotary applications.
b 33 (down) positioner for travel 1-1/4" or less.
(if you are not achieving your travel with 33 selected, change to 90)
6 Engage Gear Interlock. It is a ½" yellow selector wheel on the left side (Figure
11C). Set it to the same selection as you chose for the Transmission Ratio
Selector, 90 or 33. Refer to Figure 15 & 16 on Pages 34 & 35 for further
information.
