(5)  Carry out the start-up sequence if necessary (see chapter 3.5.2). 

(6)  Three-way valve 20 to position I, or close test valve and determine switching values "alarm 

OFF" and "pump OFF". Note values. 

(7)  The test is considered passed if the switching values measured are within the specified 

values. 

(8)  Open the shut-off valves previously closed, if appropriate. 

(9)  Three-way valve 21 to position I. If necessary, press "mute" button again. 

(10) Remove the measuring gauge. 

6.4.6  Testing the switching values using the testing device (P-115 392) 

(1)  Connect the testing device with both hose ends on one of the free muffs of three way 

valves 20 and 21 respectively. 

(2)  Connect the measuring gauge to the T-piece of the testing device. 

(3)  Close the needle valve of the testing device. 

(4)  Three-way valves 20 and 21 to position II. Operating pressure is built up in the test tank. 

(5)  Aerate using the needle valve, determine the "pump ON" and "alarm ON" (optical and au-

dible) switching values. Note values. 

(6)  Press the "mute" button if necessary. 

(7)  Carry out the start-up sequence if necessary. 

(8)  Slowly close the needle valve and determine the switching values "alarm OFF" and "pump 

OFF".  

(9)  The test is considered passed if the switching values measured are within the specified 

values. 

(10) Three-way valves 20 and 21 to position I. Press the "mute" button if appropriate. 

(11) Remove the testing device. 

6.4.7  Testing the lift of the vacuum pump 

(1)  Connect a measuring gauge to three-way valve 20. Three-way valve 20 to position II. 

(2)  Three-way valve 21 to position II, thus aeration of the pressure switch, the alarm is trig-

gered, the pump runs (carry out the start-up sequence if necessary to make the pump run) 

(3)  Read off the lift of the pump on the measuring gauge. 

(4)  The test is considered passed when the pressure value reached is  

> 150 mbar (Type 34 and 30-70),  
> 430 mbar (Type 230, 255) 
> 500 mbar (Type 330, 230-340),  
> 600 mbar (Type 410) 
> 680 mbar (Type 500) or  
> 750 mbar (Type 570). 

(5)  Three-way valve 20 and 21 to position I. 

(6)  Remove the measuring gauge.
