3.4 Installation examples
Try to only touch the AFGUARD
®
on the housing when taking it out of the box.
Remove the protection device from the optics.
Put the sealing over the thread in front of the Sensor. Only use one seal – the 1.5 mm or the
2 mm seal, which were delivered together with the AFGUARD
®
. Do not use other sealing
than the ones recommended by FAUDI Aviation GmbH.
Screw the sensor into the fitting.
Manually secure it and apply the recommended torque setting of approx. 50 Nm.
Check the sealing.
Adjust the cable. Make sure no stress is applied to the cable.
3.5 Check of Correct Assembly
Check the mounting position.
Check the recommended torque setting of 50 Nm by using of the AFGUARD
®
spanner.
Check against any leakages. Make sure the AFGUARD
®
sensor is correctly positioned.
Check the signal cable. Try to position it in a way as to prevent water from going straight to
the plug. The direction of the cable should be downwards or horizontal.
Avoid applying any stress to the cable.
3.6 Dismantling
The dismantling of the Sensor is made by reversing the steps used to install the
AFGUARD
®
.
Make sure that the power is off and the pipe work is free of pressure and empty (medium
free).
Remove the sensor plug connection.
Screw the Sensor out.
Remove the sealing,
Screw in a blind plug instead of the Sensor (do not forget the sealing).
Clean the Sensor and check it carefully.
To send the Sensor back for service purposes, please fill out the declaration of
decontamination (chapter 12), which is available for download on our Homepage.
Use the original transport box for storage and/or transport.
E
FAUDI Aviation highly recommends the use of isolating converters with transmitter
supply. Especially for use in hazardous areas, the use of inherent safe isolating
converters is mandatory. Protection classes "ia" or "ib" are allowed.
Connect the cable to the responding connecting terminals using one of the recommended
isolating converters with transmitter supply.
Finally, connect the plug with the responding plug socket at the rear end of the AFGUARD
