4.6.1.4 Calculating the Belt Tension
Calculating the Belt Tension
Example
Distance between the rollers: 235 mm
Calculation:
20000/235 = 85 (exactly 85.106…)
10 % of 85.106… = 8.5106…
Result:
Belt tension: 85 +/-9 Hz
NOTICE
For conveyor belt only
This calculation only applies to the conveyor belt.
► Define the two deflection pulleys between which you
want to set the belt tension. If possible, avoid using
the idlers for this.
► Measure the distance between the two deflection pul-
leys parallel to the conveyor belt. (see diagram)
CAUTION!
Please note that it is not always possible to just measure
the deflection pulleys from center to center.
► Calculate the belt tension using the following formula:
(20000 / roller spacing [mm]) [Hz]
The permissible tolerance is always plus/minus 10 % of
the calculated value.

Parts, tools and equipment
▪ Setting gauge for ultrasonic sensors [03076989-xx]
▪ Programming cable for PXS240 sensor [03073330-xx]
This programming cable can be used for the following sonar sensors:
– Sonar sensor PXS240 [03069863-xx]
– Sonar sensor UB100-F77 [03089004Sxx]
Setting
► Use the software to move the conveyor sides into the position which allows you best access. Alter-
natively, you can also loosen the conveyor side clamps on the dual conveyor (see "3.6.1 Loosening
the Conveyor Side Clamps" [ ➙ 143]).
► Secure the machine by attaching relevant warning tags. Do not switch the machine off as the setting
would then not be applied. Observe the instructions in section "1.2 Preparatory Work..." [ ➙ 13].
NOTICE
2 versions of the programming cable
In the meantime, a second version of the programming cable (UB-PROG2) has been supplied.
The function of this programming cable is similar to that of programming cable PXS240. Fur-
thermore, two adapter cables (M8/M12 adapter and M12/M8 adapter) can be connected for the
sensor and the conveyor control cable.
The previous programming cable will now be available under the name "UB-PROG4-V31" (old
name was PXS240) and the item no.: [03073330-xx].
► See alsoProgramming Cable for PXS240 Sensor [03073330-xx]
► To use the new programming cable, proceed as follows:
Switch on the machine and place the gauge onto the conveyor, as described. To teach,
press the "A1" button on the programming cable for approx. three seconds, until the LED
on the sensor begins to flash. The "A2" button on the UB-PROG2 is not needed.
Connecting the programming cable (example of X4I
shown)
1. Programming cable
2. Press-fit connection for the ultrasonic sensor
3. Sonar sensor
► Unplug the press-fit connection from the ultrasonic
sensor and connect the programming cable between
this and the ultrasonic sensor.

► To teach, press the button on the programming cable for approx. three seconds, until the LED on the
sensor begins to flash.
The switching threshold is set accordingly.
► Remove the setting gauge.
► Loosen the programming cable connections and reconnect the ultrasonic sensor directly to the con-
nection at the machine end.

► The distance to the PCB is defined with the setting
gauge.
Position the setting gauge over the conveyor, so that
it is above the reception area of the ultrasonic sensor.
CAUTION!
Make sure that the gauge is used the right way round.
The gauges can be used for different conveyor types.
Make sure that the gauges are always used the right way
round.
