Operation
Europress
25
The pressure in the interstitial space is regenerated.
The alarm signals must switch off automatically.
Function test by measurement
The free lateral connection of the red measurement valve is provided
for connecting a pressure gauge to test the system.
1.
Connect a pressure gauge (0-1000 mbar).
2.
Set the measurement valve (red connection) to position "Test".
The pressure gauge indicates the pressure in the interstitial
space.
3.
Set the test valve (white connection) to position "Vent".
The pressure drops slowly.
4.
Observe the gauge and record the pressure values at which the
pump and the alarm signals are switched on.
5.
Set the test valve (white connection) to position "Normal Opera-
tion".
6.
Compare the recorded values to the set values.
7.
Set the measurement valve (red connection) to position "Normal
Operation".
8.
Disconnect the vacuum gauge.
Checking the overpressure safety valve
1.
Connect a pressure gauge (0-1000 mbar) to the free lateral
connection of the red measurement valve.
2.
Set the test valve (white connection) to position "Vent".
The pump is switched on.
3.
Set the measurement valve (red connection) to position "Test
Safety Valve".
This deactivates the pressure switch; the pump remains on.
