VACUUM LEAK DETECTOR VLX .. A-Ex 3. Function Description 3.1. Normal Operating Condition The vacuum leak detector is connected to the interstitial space via suction, measuring and con- nection line(s). The vacuum generated by the pump is measured and controlled by a pressure switch.
VACUUM LEAK DETECTOR VLX .. A-Ex 4. Installation Instructions 4.1. Basic Instructions (1) Observe the approvals of the manufacturer for the tank/pipeline and the interstitial space. (2) Only qualified service companies may be used for assembly and commissioning (3) Comply with relevant regulations regarding electric installation (e.g.
VACUUM LEAK DETECTOR VLX .. A-Ex 4.3.1 Tool installation (4) Outside and inside the Ex-area (zone 1), in the open air, without any more protective box- Select the place of installation so that the ventilation in the housing (by way of convection) between the offset flange plate and slots is not impaired.

VACUUM LEAK DETECTOR VLX .. A-Ex 4.4.2 Connecting several pipeline interstitial spaces parallel to a leak detector via a distributor (see L/M 02) (1) Lay connection lines at a downward angle to the interstitial space or the manifold. If there are low points in the connection lines and lines are laid out of doors as well, install conden- sate traps at all low points.
VACUUM LEAK DETECTOR VLX .. A-Ex (5) Voltage may be only applied when: – all electric and pneumatic lines are connected properly. – the housing lid for the Ex terminal box in the tool is closed. 4.6.1 Grounding and potential compensation (1) The housing of the leak detector must be connected to the equipotential bonding of the overall system by means of the ground stud provided for that purpose.
VACUUM LEAK DETECTOR VLX .. A-Ex 5. Commissioning (1) Connect the pneumatic lines. (2) Complete the electrical wiring, but do not yet connect to the power supply. (3) Close the lids on the Ex terminal box and the housing. (4) Apply voltage supply. (5) Determine illumination of the operating and alarm lights, as well as the acoustic alarm and turn the ”mute”...
VACUUM LEAK DETECTOR VLX .. A-Ex (6) CAUTION: For single-walled tanks with a flexible leak protection lining the interstitial space can never be without pressure (collapse of the leak protection lining)! (7) A loss of power is indicated by the "Operation" signal lamp going off. A loss of power to the voltage-free relay contacts (if used for alarm transmission) triggers the alarm.
