Commissioning

7.1

Preparing commissioning

1. Pressurise the system.
2. Set an operating pressure of at least 0.4 MPa (4 bar, 58 psi).
3. Perform a functional test 

è

 7.2 Performing functional test.

7.2

Performing functional test

1. Make sure that there is an operating pressure of at least 0.4 MPa (4 bar, 58 psi) at the two

pushbutton valves.

2. Pressurise the inlets (1

1

) and (1

2

) according to the signal sequence shown in the figure below

è

 Fig. 3.

3. At each step, check whether the outlet (2) responds as in the following figure 

è

 Fig. 3.

The time offset between the inlet signals (steps 7 and 8) must be no more than 0.5 s.

Fig. 3: Functional test, step 1 … 15

The maximum permissible time offset between the inlet signals (1

1

) and (1

2

) (step 7 and 8) depends

on the operating pressure and the ambient temperature. The higher the operating pressure and
ambient temperature, the smaller the time offset needs to be.

Operation

8.1

Checking operational reliability

1. Perform the functional test monthly 

è

 7.2 Performing functional test.

2. Keep a record of the results of the functional tests.
