Adjusting the belt

CAUTION
NOTE
The conveyor system must 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.
Turn the tensioning nuts only slightly during adjusting. 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 wheel are closer together.
Figure 5
If the belt runs to the right, the right side (2) needs to be stretched or to the left side needs to be released (1).
If the belt runs to the left, the left side (1) needs to be stretched or the right side (2) needs to be released.
DANGER
4330053_A7
Rotating machine parts
Avoid any direct contact with the running conveyor belt and the outlet, feeding
and deflection points during assembly or when performing any other work.
There is an indirect risk of injuries of the fingers caused by being pulled into
the appliance and crushing.
Never reach into the hazardous area of the conveyor system. Before
switching on the conveyor system, make sure there is no risk of reactivation of
the belt.
Never catch the running belt and never wear loose clothes while aligning or
adjusting the drive drum.
Adjusting the belt
To adjust the belt, it must be monitored by two persons and switched off
immediately, if required, e.g. when the belt leaves the area around the drive
drum and rubs at the top of the conveyor belt.
The belt runs obliquely
Hazardous electrical voltage
Electrical current can pose a considerable threat to life and physical well-
being and may lead to injuries.
Only an electrician or instructed staff under the guidance and supervision of
an electrician may work on electrical systems or operational equipment; they
must comply with the electrical industry rules while doing so.
Switch off the conveyor system and secure it against unintended reactivation
after the belt has been adjusted.
