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 fixed 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, flat 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.
