You can uniformly adjust the height of the conveyor system by means of the screw feet. Adjust
deviations with a spirit level in the cross direction. Normally, the height is 35.5'‘ (900 mm).
When assembling begin with the end of the belt. When doing this, place the first segment on the
marked position.
Screw the segment under the next part of the belt. When doing this, the first person should hold the
segment while the second person is pushing the next part of the belt on to the connector of the
segment the first person is holding.
Put together the edges of the segments so that they are flush and screw them together from below.
Continue with the assembly as described above.

Check again the inclination and align the conveyor system horizontally with the spirit level until it is
level.
4.2.2 Pulling up the belt
ATTENTION Damage to property
Do not overstretch the belt, otherwise this will ruin it.
Make sure that the belt is not overstretched.
NOTE Arranging the belt
Make sure that the smooth PVC surface is at the top when unrolling and
arranging the belt while the rough surface is on the rollers.
Do not twist the belt when arranging it.
After the conveyor system has been assembled, pull up the belt.
Proceed as follows:
Remove the packing material from the belt.
Remove the boxes at the beginning and at the end of the belt and place the belt on the top of the
conveyor system.
Pull the belt (the chain is already connected) to the deflection pulley at the beginning of the conveyor
system.
Put the belt onto the conveyor rollers under the conveyor system and move along the driving roller
until it will reach the limit rocker switch at the beginning of the belt.
If the chains are not fastened, you can move the belt over the driving rollers in the reversed
sequence. There is no obligatory sequence how to arrange the belt.
Pull the belt over the upper side until the ends of the belt are facing each other at the middle of the
conveyor system.
Join both ends of the belt together and fasten with the plastic strips (connection elements). The
plastic strips hold now the both ends of the belt together.
Check the position of the belt and adjust it so that it lies exactly at the top of the conveyor system.
4.2.3 Stretching the belt
After the belt has been fastened, you have to stretch it:
Mark a distance of 39’’ (1000 mm)on the belt with a pencil (no pen).
NOTE Length of the belt
A length of a perfectly stretched belt is from 39.5 to 39.6’’ (1003 to 1005 mm)
at a strain from 0.5 to 0.7% (pay attention to the marks made with the pencil).
To adjust appropriately the belt turn both tensioning nuts on the threaded rods at the deflection.
The belt must be stretched so that the clearance between both ends of the belt is not more that 0.08’’
(2 mm).
After you have stretched the belt appropriately, if needed cut the plastic strips protruding on the sides
so that they are uniform with the width of the belt.
Finally, scorch and seal these both places with a small flame (e.g., with a lighter), so that the plastic
strips cannot slip out any more.

4.2.4 Adjusting the belt
ATTENTION Rotating machine parts
There is a risk of crush injuries and injuries caused by being pulled into the
appliance when adjusting the drive drum.
Never catch the running belt and never wear wide clothes while aligning or
adjusting the drive drum.
NOTE Adjusting the belt
Before adjusting 2 members of the staff should keep watching the belt and
switch it off immediately if necessary, for instance, if the belt is running out of
the area of the drive drum or the belt is dragging along the surface of the
conveyor system.
The conveyor system is to be connected to the mains to align and adjust the belt.
To align and adjust the belt, proceed as follows:
Switch on the conveyor system and allow the belt to start slowly and carefully running (at most the
level three).
Adjust the movement of the belt by turning the tensioning nuts on the threaded rods at the deflection.
When adjusting, turn the tensioning nuts only slightly. A ¼ of a turn is usually enough.
The belt moves always to the side of the smallest clearance of the axles. It is the side where the drive
drum and the deflection pulley are closer together.
Figure 4The belt runs obliquely
If the belt runs to the right, so you have to stretch the right side (2) or to release the left side (1).
If the belt runs to the left, so you have to stretch the left side (1) or to release the right side (2).
DANGER Hazardous electrical voltage
The electrical voltage may be considerably dangerous to limb and life of
persons and lead to injuries.
All work on electrical installations or operating materials should only be
carried out by a certified electrician or by trained personnel under supervision
and monitoring of a certified electrician according to the certain electro-
technical regulations.
Switch off the conveyor system and secure it against unintended reactivation
after the belt has been adjusted.
After the belt has been taken out of operation, you can fit back the limit boxes and other removed
parts. Screw and fasten the counter nuts on the threaded rods.
Switch on the conveyor system and allow the belt to start slowly and carefully running.
Pay attention to the proper run of the belt and unusual noises. The belt may not drag along the top of
the belt system, the limit boxes or other parts.
After you have made all settings you can put the conveyor system into operation. There should be no loads
on the system while putting it into operation. This is the only way to detect causes of initial start-up
difficulties.

4.3 Putting into Operation
DANGER Hazardous electrical voltage
The electrical voltage may be considerably dangerous to limb and life of
persons and lead to injuries.
All work on electrical installations or operating materials should only be
carried out by a certified electrician or by trained personnel under supervision
and monitoring of a certified electrician according to the certain electro-
technical regulations.
Before starting work switch live parts voltage-free. Ask another person to
assist you that can press the Emergency Stop button in case of emergency.
Check the premises before setting up the conveyor system. Flaws can be detected and improved at an early
stage. Observe the following points before setting up the conveyor system:
The floors in the premises where the appliance is to be set up must be level and correspond to the
required load-bearing capacity of 196 N/m² (20 kg/m²).
We do not recommend dowelling the conveyor system with the floor of the premises because of the
moisture barrier layer existing in the most of cases.
There must be a possibility after consultation to connect the conveyor system to the mains.
The user of the conveyor system must take other measures beforehand to ensure the safety of the operating
staff:
Specify the field of application and draw up corresponding safety instructions.
Instruct the operating staff in safety.
Give the operating staff training.
Mark hazardous areas.
4.3.1 Connecting the conveyor system
The following points are to be observed when connecting the conveyor system:
Have the power supply installed and the conveyor system earthed in a professional manner.
Protect power supply cables against exposure to moisture.
In case of unintended reactivation, stop the appliance by using the control system.
Technical specifications of the mains in some countries deviate from those given in these operating
instructions. Thus, the connecting data of the conveyor system should be harmonized with the data of the
local power mains. Compare the specification given in the rating plate with the local electrical specifications.
To connect the conveyor system, proceed as follows:
Connect the connecting cable with the distributor of the conveyor system.
Connect the three-phase motor so that it rotates in a specified direction.
