on Industrial Fieldbus 2 vacuum levels to match precise application needs Suction flow rate (Nl/min) : • Air Saving Regulator 40 % of energy savings on average. ■ Air Saving Control 90 % of energy savings on average. 2 integrated energy-saving technologies 40 % energy savings (on average, see p.4). Combination of non-return valve © and advanced electronics © ensures ASC's automatic performance. Once vacuum is established, the pump no longer consumes air to hold the product. LEMCOM series vacuum pumps, which integrate an ASR “venturi regulator” combination, maintain ideals that COVAL values...

MINI-VACUUM PUMP WITH FIELDBUS COMMUNICATION, LEMCOM SERIES - 5

Individual or island modules? Stand-alone modules are suitable for the most common applications: one module controls one or more suction cups, all of which operate according to the same sequence. When several suction cups are operating according to different sequences, multiple modules are required, which can be: several autonomous modules, OR a group of these modules with an internally shared pressure supply The illustrations shown here guide the selection: autonomous modules are coupled with integrated pressure regulators (ASR) in a group, the integrated regulator is eliminated: to...

communication for all processes A setting for every application The LEMCOM is based on an innovative, efficient product structure: The "master" module manages communication on the fieldbus, assures management of the "secondary" modules and is a fully-integrated vacuum pump. Its 2 communication ports enable a continuous fieldbus. The "secondary" modules are interconnected with the "master" module via the COVAL bus. Contact between the "master" module and the "secondary" modules is confirmed by an M8 connecting bridge for island configurations or by a M8/M8 standard cable for configurations...
