Operation
5.4.1 Installing limit switch
Only necessary for fi ttings with limit switches.
DANGER
Risk of electrocution!
All electrical work must be carried out by quali fi ed electri-
cians only.
1. Mount limit switch unit onto fi tting.
2. Connect limit switch:
– ( → Figure Limit switch, type VCSP, Page 8).
– ( → Figure Limit switch, type Nj2–V3–N, Page 8).
– ( → Figure Limit switch, type NBB2–V3–E2, Page 8).
5.4.2 Pneumatic connection
Solenoid pilot valves are available for control of the com-
pressed air drive:
– 3/2-way valve for single-acting drives
– 5/2-way valve for double-acting drives
CAUTION
Risk of injury from compressed air!
All work on the compressed air system must be carried out
by quali
fi ed technicians.
Connect compressed air lines to the compressed air drive.

5.4.3 Checking the function of the drive
Open and close fi tting using the pneumatic connection, the
indicator pin signals the corresponding position
–
lowered: Fitting is closed
– protruding: Fitting is open
5.5 Performing the hydrostatic test
Pressure test using neutral medium, e.g. water.
1. Pressurize the fi tting, ensuring
– Test pressure < permissible system pressure
– Test pressure < 1.5 PN
– Test pressure < PN + 5 bar
2. Check the fi tting for leaks.
6 Operation
6.1 Commissioning
Fitting correctly installed and connected
WARNING
Risk of injury and poisoning due to medium spraying out.
Use personal protective equipment when carrying out any
work on the
fi tting.
1. Open and close fi tting, the indicator pin signals the corre-
sponding position
–
lowered: Fitting is closed
– protruding: Fitting is open
2. After the initial stresses due to pressure and operating tem-
perature, check if the fi tting is sealed.
