LEMAX Series: Integrated Intelligence vacuum resumed airtight object Adaptation Intelligence airtight object Communication Intelligence The above example shows the LEMAX module's capacity to adapt from one cycle to another: The LEMAX module's integrated intelligence also controls the following communications: Signals sent - "Gripped product" signal. - "ASC missing" signal and, in complement, a blinking alert message on the display panel. The ASC regulation process starts automatically. Due to microleaks, vacuum is automatically restored according to need. If uncontrollable leaks arise (here...

Stand-alone and Island Modules The LEMAX series offers 2 module configurations: The complete solution to the most common applications, where all vacuum pads are working according to the same sequence. stand-alone module They are individually fixed, supplied and controlled. Their integrated 3.5 bar pressure regulator allows a direct supply from the air pressure network, from 4.5 to 7 bar. See p. 6 and 7 for the part numbers, connections and mounting options for stand-alone modules. An island may be convenient for feeding vacuum pads following different sequences. common pressure unit (4 bar)...

LEMAX Series: Island Island Composition The island modules are modularly banked to form a compact island. Each module is separately controlled in order to feed its vacuum pad(s) according to the required sequence. P optimum : 4bar (working from 4 to 7 bar) The island operates with a common pressure core that feeds each module. This common core receives pressure at either end, or both ends if needed. The maximum number of modules in an island depends of the power of the modules that must be active simultaneously: 5 modules maximum for Ø1.4 mm nozzle. 7 modules maximum for Ø1.2 mm nozzle. 9...

LEMAX Series: Applications The LEMAX series mini-module vacuum pumps offer a new approach to vacuum handling in numerous domains: packaging, robotics, clamping, transfers, plastic molding, etc... Optimized to serve small and medium sized suction cups, LEMAX helps to simplify the installation while integrating all control functions into a single lightweight mini-module, placed close to the suction cups. Integrated in all LEMAX modules, the ASC mechanism automatically provides 60-99% energy savings when handled products are airtight. If porous products are also handled, production continues...
