STRUCTURE

The belt(*1) of S-CON®MINI/SANIVEYOR®CURVE is conic and equipped with the guide roller units(*2)
on the surface and undersurface of the outside edges. These guide roller units are attached at regularintervals and control the belt travel by running along the arc guide rails(*3, *4, *5, *6)(upper and lower
guide rails for each of carrying and returning sides). Therefore it is unnecessary to adjust the beltalignment as long as the belt is installed correctly.

4

MAXIMUM SIZE OF HANDLED MATERIALSThe effective belt width of S-CON®MINI/SANIVEYOR® CURVE is limited by the guide rails. The maximum
size of handled materials is determined as shown below, according to the belt width and inside radius.
Make sure that the handled materials are within the maximum size.

■ Caution When Using Inverter

CAUTION

1. Be sure to confirm that the power source voltage is within the rated voltage
range, before switching ON the power source. (Voltage exceeding the rated
voltage could cause fuming, abnormal noise, etc.)
2. Be sure to start and stop the conveyor with RUN/STOP switch. When startingand stopping the conveyor frequently in a short period (tact operation etc.), it is
impossible to start/stop the machine by turning on/off the power supply. In thiscase be sure to start and stop the machine by external signals. (Inverter
variable-speed type is different from speed controller’s, and the power supply
will trip.) Do not start and stop the conveyor excessively frequently. It may cause
machine failure or shorten its service life.
3. The RUN/STOP switch of inverter unit is not for turning the power on and off.
When leaving the conveyor unused for a long period, make sure that the mains
is off.
4. Do not run the conveyor at excessively low speed for a long period, or start andstop the conveyor excessively frequently. These may cause machine failure or
shorten its service life.
5. Do not touch the inverter radiator of side of inverter unit, and do not allow any
material to touch it, because of its high temperature.
6. Use the inverter unit within the permissible range of ambient temperature (from–10℃ to ＋40℃). Avoid freezing.
7. Pay special attention not to allow any foreign matter (dust, iron powder, etc.) to
get into the inverter unit.
8. Operating the motor using the inverter could cause noises from the inverter I/O
cables, motor, etc. Keep in mind that these could interfere with the correct
operation of other electronic devices. (In this case, noises and their effects canbe suppressed to some extent by providing the inverter I/O with a filter orotherwise shielding the power cable.)■ Direction of Conveyor Travel
For S-CON®MINI/SANIVEYOR® CURVE, it is impossible to change direction of conveyor travel on
account of machine structure. Use machine in the direction arrow mark sticker shows. (→See p.6.)
NOTE: Occasionally machine has a reverse switch. Since this switch is only for factory adjustment, do nottamper with it.
