Pressure build-up: The internal motor pump increases the gas pressure in the test section by approx. 20 mbar comred to the input-side pressure applied to valve V1. During the test riod, the installed differential pressure switch monitors the test section for leakage. If the test pressure is attained, the motor pump is switched off (end of test riod). The release time (10-2 s) dends on the test volume (max..0 l) and input pressure (max. 00 mbar). If the test section is tight, the contact is released to the automatic burner control after max. 2 s - the yellow signal lamp lights up. If the test section is leaky or if the pressure increase by + 20 mbar is not attained during the test riod (max. 2 s), the switches to fault. The red signal lamp lights as long as the contact release by the regulator or thermostat is present (heat requirement). If there is a short power failure during the test or burner oration, the test is started again automatically. If the pumping time < approx. 10s, the pressure difference between the testing system and the inlet pressure is balanced after pumping is finished. Oration: The internal valve of the is closed. 12

9 Startup 1. Check test section for leaks after assembly. 2. Start test by using temrature regulator and/or restart or by pressing the reset button of.. If the test section is tight Dending on the length of the test section and the residual pressure applied, the pumping time is between s and 2 s. The release for the automatic burner control is then given after approx. 10 s at the earliest (at small test volumes and small input pressures) and after approx. 2 s at the latest (at large test volumes and large input pressures) - the yellow signal lamp lights up. If the test section is leaky The test pressure is not attained. The motor pump switches off, the red fault lamp lights up. Switch-through to the automatic burner control does not take place. Functional check By oning a screw plug in test nipple p 2 (p a ) during test riod (pumping time), leakage can be simulated and a function check can take place. Setting The must not be adjusted on site. Assembly Directly flange the laterally to the DUNGS multiple actuators (mounting is possible on left-hand or right-hand side) using two 10. x 2.2 O rings and four M x 1 self-tapping screws. If an exhaust gas valve is installed in the boiler, it must be on at the beginning of the test. In order to prevent functional and leakage problems, we recommend the use of solenoid valves as r EN 11 Class A and Class B. Insufficiently shielded frequency converters could cause faults in the VPS due to network disturbances. Make provisions for sufficient electrical shielding. 9 12
