Installation and start-up
The installation measures described in this manual must only be carried out by trained
specialists. The applicable regulations for electrical engineering must in any case be
observed and complied with.
Preparations
ATTENTION!
Choose an installation location, at which the device is neither ex-
posed to extreme temperatures, nor to extreme humidity. The ambient
temperature must be in the range from 0 to 50 °C, the relative hu-
midity must not exceed 90 % and no condensation should occur.
The device must stand in a firm position, protected against vibration.
Avoid a location near heating or air conditioning systems.
Make sure that the supply voltage matches the supply voltage specified on the type plate.
Only install the device inside a control cabinet, if adequate ventilation is assured.
Position the device as close as possible to the specimen, in order to maintain the test
circuit volume at a low level and to achieve more accurate measuring results.
Keep a space of approx. 100 mm behind the back of the unit for electric cables,
pneumatic hoses and connecting plugs.
Connecting peripheral equipment
Before you can start up the tester, the following connections must first be made:
to the compressed air supply, optionally to the test medium, to specimen and refer-
ence volume, to the machine control, to the data output through a serial interface and
to the power supply. Only then is the leak tester ready for operation.
DANGER caused by electric current!
Separate the device from the electric power supply before connecting
device components.
Before connecting compressed air/test medium
In case of major pressure fluctuations in the compressed air supply network we rec-
ommend the installation of a pressure switch, which will emit an electrical output sig-
nal when the pressure drops. This signal can be used for display/machine shut-down
purposes. Install a filter unit (min 1µm) in the supply line at a safe and well visible lo-
cation, to ensure the supply of dry, oil free compressed air. Check the service unit at
regular intervals to prevent the device from being soiled by oil. Include the inspection
and changing of filter cartridges in the maintenance plan; this applies also for filters
with automatic condensate drainage.
NOTE!
Warranty claims will not be accepted if the tester is damaged by oil
and/or water entering into the unit.
