Inspection and Adjustment following Initial Power-up

The conveyor belt may have to be adjusted. It is important that this belt remain centered
while the equipment is running. A conveyor belt tends to center itself at the point of
highest tension. Due to the convexity of the drive roller, this point is the middle of the
conveyor unit. Prerequisite is, however, that the track roller and drive roller are parallel to
one another. To center the belt, adjust the clamping screws on the track roller.
§ Check whether the conveyor belt centers itself toward one side, so that it is no longer in
the middle.
§ If the conveyor belt centers itself toward one side, adjust the clamping screws on the
track roller until the conveyor belt centers itself in the middle.
§ The belt is farther to the right:
loosen the clamping screw on the right and tighten the clamping screw on the left.
§ The belt is farther to the left:
Loosen the clamping screw on the left and tighten the clamping screw on the right.
§ Following this adjustment, tighten the locknuts to prevent the clamping screws from
working loose.
§ After approximately 1 hour of operation, check the setting. Use of the conveyor belt may
cause a change in its position.

Target Speed

The target speed of the conveyor belt is set at the factory to the value indicated on the
order when the equipment was purchased. If no value was indicated, the conveyor belt is
set to a median speed (approximately 25m/min). To modify the speed, parameter P4 must
be changed in the frequency converter:
higher value = higher rate of speed
lower value = lower rate of speed
Please refer to the operating instructions for the frequency converter for details (delivered
inside the control cabinet).

Product Detection

Product detection is implemented using photo sensors at the end of the weighing
section. As a rule, these are one-way photo sensors consisting of a transmitter and
a receiver, or reflected-light sensors. The weighing platform is designed to be as rugged
and reliable as you require in your industrial applications.
