5. Loosen the two fixing screws ⑥ of the basic electronics.
6. Remove the basic electronics ⑤.
7. Remove the fixing screws ② of the pneumatic block ①.
Four screws for the single-acting pneumatic block. Five screws for the double-acting
pneumatic block.
8. Remove the pneumatic block ①.
Make sure that the cord seal ④ of the pneumatic block is in the pneumatic block.
9. Blow the existing dirt from the surface on which the pneumatic block was placed.
10.Remove the pressure sensor module ③ and the cord seal ④ of the pressure sensor
module.
Installation
1. Insert the new cord seal ④ into the new pressure sensor module ③.
2. Press the cord seal ④ into the groove on the pressure sensor module ③ on all sides.
3. Place the pressure sensor module ③ on the baseplate.
4. Place the pneumatic block ① on the pressure sensor module ③.
– Make sure that the cord seal ④ of the pneumatic block is in the pneumatic block.
– Make sure that the pneumatic block engages with the centering elements ④ (Page 202)
on the baseplate.
5. Screw the fixing screws ② into the pneumatic block ①.
6. Tighten the fixing screws ② with a torque of 1.1 Nm.
7. Place the basic electronics ⑤ onto the four holders of the adapter ⑧.
8. Screw in the two fixing screws ⑥ of the basic electronics.
9. Tighten the fixing screws ⑥.
10.Insert the ribbon cable ⑦ and all other ribbon cables onto the basic electronics ⑤.
11.Place the plastic cap ⑨.
12.Close the positioner as described in section "Closing the standard and and intrinsically safe
version (Page 53)".
13.For a positioner with order option -Z F01 "Fail in Place", adjust the parameter '51.PNEUM'
Pneumatics type (Page 160) from "Std" to "FIP".
14.Switch on the supply pressure PZ.
15.Initialize the positioner as described in section "Commissioning (Page 105)".
Result
The pressure sensor module is ready to use again.
