Application:
Kiepe Belt Misalignment Switches are used in conveyor
installations for monitoring the true running of conveyor belts.
The switches, when mounted at the running edges of a conveyor
belt, will be operated if the belt deviates from it’s designed
running line by more than a permissable distance.
The Kiepe Belt Misalignment Switches HESEX are approved for
use in areas with combustible dusts acc. to EN 50281-1-1, part 1-1:
Electrical apparatus protected by enclosures.
The switches are marked with ATEX II 2D IP 65 T 85 °C and
can be used in zones 21 and 22, equipment group II, categories
2 and 3.
The Belt Misalignment Switch HESEX is used for conveyor
installations subjected to especially severe operating conditions.
The actuating roller of stainless steel is carried in stainless steel
ball bearings for improved handling of laterial forces and jerks.
The large roller diameter of 48 mm permits the use of this device
where fast belt speeds prevail. All external parts are either of
stainless steel or have been specially plated.
The trip points are to be adjusted within 5 and 15° resp. 15 and
35° by means of movable actuating cams.
Technical Data:
Accessories:
Use only cable glands and plugs recommended by the manufacturer and supplied with the switch. These cable glands and plugs are designed acc. to ATEX EU design sample test certifi cation.
The use of other cable glands and plugs may lead to a void device type approval.

Application:
Kiepe Belt Misalignment Switches are used in conveyor installations
for monitoring the true running of conveyor belts. The
switches, when mounted at the running edges of a conveyor belt,
will be operated if the belt deviates from it’s designed running
line by more than a permissable distance.
The switches will then stop the conveyor drive, avoiding spillage
of material or damage to the plant. The Belt Misalignment
Switches can be optionally supplied with a pre-alarm position for
an alert signal at slight deviation and a fi nal cut-out and lock. All
switches are maintenance free.
Product Description:
The switch enclosure consists of corrosion-resistant aluminium
alloy. All external parts are either of stainless steel or have been
especially plated. The actuating roller is of polyamide. All VGtypes
ars fitted with snap acting switches. The actuating head is
removable from the main switch body and may be re-fitted in any
of four positions. This, together with re-positioning of the switch
trip bar allows the actuating roller to operate in any of four directions
giving greater mounting versatility. All this will insure
extremely safe operation, permitting to use the switch for severe
operation and in outdoor installations.
No maintenance will be required. For the Models VG…/5 and 6
the switching point has been set at the manufacturer’s plant to
approx. 12° from vertical and can be continuously readjusted in
the field. The Model VG…/6 switch will latch as the admissable
amount of out-of-line running is exceeded. It is unlatched locally
by resetting the actuating roller. The VG 133/6 switch is equipped
with two snap acting switches. An alert signal will be brovided
at approx. 12°, the final cut-out and latch will occur at 45°. For
unlatching, the actuating roller is reset by hand.
