Firstly; Complete the mechanical installation
of the switch, then complete the electrical
installation.After all operations are complet-
ed, the electrical energy can be activated
and conveyor operation can be started.
NOTE
Open the cover of switch by loosening the
four slotted lid screws. There are max. 3
micro switches in the installation space of
the switch. Wire the contacts according to
the requirements demanded by the line
at-site. After wards put on the cover again
and tighten screws with a torque of 3 Nm.
Tighten the cable screwing according to the
instructions.However, at a maximum torque
of 6 Nm.
Control: It must be checked whether the
switch is operationalized mechanically and
electrically or not before the system turn on.
ELECTRICAL INSTALLATION
1- Adjust the switch as the switch roller
points towards the belt area,note that the
conveyor belt is in it's normal position and
the carrying roller is at a medium height. It
should have the same height as the edge of
the belt. The switch is xed with two suitable
screws.
2- The alignment switches are used on either
side of conveyor systems to provide a
fail-safe stop mechanism for belts that have
misaligned left or right. They are typically
installed at the header and tail pulleys on all
conveyors and at trippers drive on belts.
Once activated these switches isolate the
control circuits of the motors driving the
conveyors and other process equipment.
3- The alignment switch roller surface should
not be in contact with the belt under correct
alignment conditions. We recommend a 10
clearance as per diagram below.
4- The alignment switch must be installed so
that the roller on the lever is always at 90
degree to the conveyor belt for correct
operation as per diagram below
Maintenance: There is no need of any
maintenance works for KBT conveyor belt
safety switches due to prooven construction
and high material quality.
MECHANICAL INSTALLATION
NSR / TPR Series conveyor belt misalignment
switches are designed to stop conveyor
systems during emergency or maintenance
and repair work. Designed to withstand
heavy conditions, makes it suitable for most
industrial applications that are reliable in the
long term.With belt misalignment switches,
the system saves money by reducing down-
time and maintenance costs.
This type of belt misalignment switches are
mounted on the left and right sides of the
belt in pairs. In case of misalignment of the
belt, it is shifted against the reset force of the
inner spring by touching the lever. Max. lever
sliding angle is 75 °.
In case the belt deviates from the target; The
latch can be released by lifting the reset
handle. Reset can also be done
automatically.
Ensure that the conveyor is electrically
isolated and stationary before carrying out
any work any conveyor equipment. Only
a competent electrician should carry out
electrical installation,repairs or maintenance.
1- In order to install the switch or switches, at and
solid console or consoles should be determined in
the frame of the conveyor belt and the mounting
points should be planned.
2- Necessary mechanical and electrical hand tools for
installation must be provided.
3- Necessary work clothes should be put-on in terms
of work safety.
4- Before electrical connection, electrical energy
should be disabled.
