GASSONIC SURVEYOR, Руководство пользователя

Страница: 6 / 28

The Gassonic Surveyor is an intrinsically safe (Ex-i) ultrasonic gas leak detector. The cables are connected through M20
x 1.5 cable entries in the top part using glands according to Ingress Protection class IP66. The inner cores of the cable
penetrating the detector should be 200 mm long. This will ensure no tension on the wires and the connectors when the
unit is opened. The two mounting bolts are on the top part of the detector. This means that the cables will enter on the
fixed part of the detector. The bottom part is attached to the top part by means of four allen screws with water sealing
washers. Loosening these screws will expose the connectors. The screws will be retained in the bottom part and will not
drop out. The bottom part of the detector is supported by the Load-strap, which is connected to the top part.

The Gassonic Surveyor is mounted from the top with two 8 mm stainless steel bolts. Maximum thread depth is 15 mm. To
open the unit, loosen the four screws. The screws are secured, and will not drop out. When closing the unit use a torque
of 6Nm on the 4 screws.
The lower part of the unit is supported by a solid cable strap on which it can hang while connecting the cables.
When connecting the cables and moving the jumpers, the power of the unit must be switched off.
