  • Page 6 VACUUM LEAK DETECTOR VLX ../A-Ex 3. Function Description 3.1. Normal Operation The vacuum leak detector is connected with the interstitial space via suction-, measuring- and connection line(s). The vacuum generated by the pump is measured and controlled by a vacuum switch. When the operating vacuum is reached (Pump OFF), the pump shuts off.

    VACUUM LEAK DETECTOR VLX ../A-Ex 4. Installation Instructions 4.1. General Notes (1) Observe the approvals of the manufacturer for the tank/pipe and the interstitial space. (2) Only qualified service companies may be used for installation and start up (3) Comply with relevant regulations regarding electric installation , (e.g.
  • Page 8 VACUUM LEAK DETECTOR VLX ../A-Ex 4.3.1 Installation of the leak detector (4) Outside and inside the hazardous location (zone 1), in the open air, without any more protective boxes. Chose a mounting place, where the ventilation in the housing (by convection) between the flange plate (be distant to the housing) and the vent opening is not being effected.
  • Page 9 VACUUM LEAK DETECTOR VLX ../A-Ex (10) Leak detector side flame arresters:  Are necessary, when either the suction line or the exhaust line (or both) are connected to zone 0.  Are not necessary, if both the suction line and the exhaust line are NOT connected to zone 0.

  • Page 13 VACUUM LEAK DETECTOR VLX ../A-Ex (2) Frequent switching on or continuous running of the pump indicates leaks, which should be corrected within a reasonable time. (3) If the alarm goes off, this always indicates a more significant leak or a defect. Determine the cause and correct it shortly.
  • Page 14 VACUUM LEAK DETECTOR VLX ../A-Ex (7) As part of the annual function test, check the motor of the pump for running noises (damaged bearings). (8) If the pump has to be changed or when working on the pumps exhaust line a pressure test of the suction- and measuring line with 10 bar has to be carried out for the parts inside the housing.
