Level sensor adjustment
for any type of dust
DANGER
There is a risk that material deposits in the inlet isolation device might
not be detected if the level sensor is not properly adjusted!
This could lead to malfunction of the inlet isolation device if the flap blade does not
close properly in the event of an explosion. Explosion pressure/flame passage to
upstream system areas could be the result
--------------------------------------------------------------------------------------------------------
a) Ensure that the system is disconnected.
b) Ensure, through a supervisory person, that the system is not able to be
restarted while inspecting.
c) Open the inspection lid (see Section 9.4 Inspection lid opening and closing
WARNING
Danger of head injuries due to protruding flap stopper when inspection
lid is opened!
Please watch out for the protruding flap blade stopper while working inside the inlet
isolation device. If necessary, equip the stopper with a bumper during the
maintenance process. The bumper must be removed prior to closing the inspection
lid.
--------------------------------------------------------------------------------------------------------
d) Accumulate some of the process material. Add a small amount of the dust into
the inlet isolation device. The dust accumulation should be large enough that
the level sensor is completely covered with a dust pile that is approximately 10
mm high. The material accumulation can be as high as the flap blade’s ability
to open will allow.
