L - Locate Unit (10)


To replace / install an up / down sensor mounting block, please proceed as follows:
  1. Dispense the pneumatic air supply from the locate unit.
  2. Loosen the four attachment bolts (M4) of the sensor block underneath the stop unit.
  3. Remove the sensors from the sensor block.
  4. Remove the four bolts completely.
  5. Mount the new sensor block in the same orientation to the index unit, but do not tighten the mounting bolts yet.
  6. Slide the sensors into the provisions and adjust the switching distance. (Please make sure that the sensors get installed in the same locations as before. Otherwise it will cause program failures)
  7. Tighten the bolts with a standard torque for M4
  8. Press the index pin down manually and...

To replace the entire Locate Unit body, please proceed as follows:
  1. Disconnect the electrical and pneumatic power supply of the entire conveyor system and secure against reconnection.
  2. Mark the pneumatic hoses and remove them from the fittings.
  3. Mark the locations of the up / down sensors and take them out of the bracket.
  4. Remove the four attachment bolts (M8) of the index unit body to the base plate / holder and remove the entire base body to the top.
  5. Install the new base body in reverse order.
  6. Re-connect the pneumatic tubes and the sensors. Please pay attention to the marks, that the previous configuration gets restored to avoid malfunctions.
  7. Push an empty pallet manually in the stop unit...

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 damages and detection of leaks

The pneumatic installation of the Locate Unit has to be done according to the pneumatic diagram to ensure the correct operations of the unit. The supplied air fittings are designed for 6 mm air tubing. The supplied compressed air must be dried and filtered and the pressure must be set in the defined range.
 
The index pin home position should be down even if the mechanical spring loaded home position is up. This is done so that in case of a pressure loss all pallets will stop in front of the index pin. The index pin can be used as spring extended or actively, which is recommended to ensure a proper alignment of the pallet even with high loads.
 
The integrated and installed LOGO!MAT Stop...

The control of the Locate Unit must only be done automatically and should be done according to the following recommendations:
 
It is a requirement that the spring-loaded index pin home position is pin down (S2 active). That allows the pallet to pass the pin to go into the stop unit. 
 
Locate Unit with cushioned stop unit:
  1. The pallet hits the cushioned stop unit, gets cushioned and actively pulled into its end position. The pallet is stopped and sensed by the signals (S5 / S3 / S4).
  2. The index pin can be extended (S1) to index the pallet. The position is reached if the stop unit is in its final position, the pallet is present and the locator pin is fully extended. (S4 / S5 / S3).

To install the Locate Unit into a LOGO!MAT Roller Conveyor, please proceed as follows:
  1. Mark the intended installation area and adjust the roller locations to allow the required opening if necessary. Stub rollers should only be used if no other configuration of full rollers is possible. Please see the details about changing rollers in the documentation of the "Roller Conveyor".
    The additional rollers or stub rollers are not scope of supply. The required rollers have to be ordered separately if an additional Locate Unit has to be installed.
  2. Install the Stop Unit at the desired / required location within the roller conveyor. Please see the detailed information for the installation of the stop unit...
