The roller configuration in the area of the Stop Unit is very important to guarantee a continuous flow after releasing the pallet from the Stop Unit. Rollers can be shifted in increments of 68 mm; stub rollers can be used for additional support of the pallet. Sensor holders or RFID tag brackets should be arranged in the roller spacing to avoid stub rollers in these areas. Attention should be taken to have at least three (3) full rollers (not stub rollers!!) in contact with the stopped pallet when the pallet is in its end position of the cushioned Stop Unit. For better performance of the pallet, it is more effective to use additional full rollers to add friction surface than increasing the friction...

Only authorized personnel are permitted to install a Stop Unit. Before the Stop Unit can be fitted, you should unpack, clean and look for any damage. If there is damage, document and repair before starting the installation.
Attention must be paid to the positioning of the Stop Unit. There must be at least a distance of 20 mm between the adjoining roller (outer diameter) and the Stop Unit body in the end and home position to avoid possible pinch points.
A displacement of a Stop Unit can also be done according to the following installation instructions:
  1. Disconnect the Stop Unit from the compressed air supply to avoid injuries.
  2. Remove the Stop Unit base plate from the mounting clamps.
  3. Bring...

All LOGO!MAT Components are developed to make very little preservative maintenance necessary but all components will last way longer if the following tasks get do in the shown intervals. The maintenance and inspection work listed below is to be carried out at the listed intervals to keep the warranty and to follow up constantly if the LOGO!MAT Component is working well. Any defects found must be documented and fixed before operating again. All time specifications are based on single-shift operations.

With an interval of one (1) month the following preservative maintenance should be carried out:
  1. Check all parts for wear and damage.
  2. Visual check of the unit for proper function, damages and detection...

The control of the 2-way Diverter has to be done automatically!
To control the transfer of a pallet from an adjoining conveyor segment to the main track by the LOGO!MAT 2-way Diverter, please use the following recommendations:
  1. The arriving pallet must be stopped in front of the diverter area by a LOGO!MAT Stop Unit. The presence of the pallet must be detected by the pallet present sensor.
  2. Depending on the desired conveyor flow direction (right or left), the two-corner element must be positioned accordingly. The right flow direction of the conveyor segment has to be ensured.
  3. If the required position of the two-corner element is confirmed by the end position sensor, no other pallet is located...

For the electrical installation, sensors have to be installed in the provided brackets. The wires have to be protected against chafing and secured against unintentional removal. Please pay attention to the correct switching distance and the right sensor size. The controls of the sensors and the used logic can influence the function and the entire performance of the 2-way Diverter dramatically. This is the responsibility of the operating company.
The drive unit has to be controlled properly and secured by a motor starter. Softer movements of the 2-way Diverter are possible, if a frequency converter is used.
