Lift & Locate Unit: %Pneumatic Installation


The pneumatic installation of the Lift & Locate Unit has to be done according to the pneumatic diagram to ensure the correct operation 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.
 
Flow controls should be used to adjust the lift and lowering motion of the unit.
 
A clamping unit has to be installed directly to the main air supply to ensure an immediate reaction to a pressure loss. This unit shouldn’t be used for holding the Lift Locate in a certain position.
 
The integrated and installed LOGO!MAT Stop Unit (cushioned or non-cushioned) has to be connected pneumatically according to the stop unit documentation.

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 control of the sensors and the used logic can influence the function of the Lift & Locate Unit tremendously. This is the responsibility of the operating company.
 
The integrated and installed LOGO!MAT Stop Unit (cushioned or non-cushioned) has to be equipped with sensors according to the stop unit documentation.
 
To operate the Lift & Locate Unit as safely as possible, please comply with the following information!
  1. Operating the Lift & Locate Unit without a pallet in place is forbidden.
  2. The integrated Stop Unit (cushioned) must only move in its home position if the pallet is directly over the Lift and Locate Unit!
  3. All service and maintenance work must be performed by authorized technical personnel only and must be  performed with all energy devices (e.g. electrical or pneumatic power) shut down and secured against reconnection.
