Modification of Electro - Pneumatic Elevator System depending on the air pressure and flow rate determinations

Abstract

The paper presents Determination of pressures and flow for an Electro-pneumatic elevator system controlled by PLC to achieve the requirements modifications for improve presence model. The controller used for the prototype was implemented in Ladder logic on a PLC. The PLC used for this work is (LSGLOFA-G7M-DR20A) series with (8) input and (12) output and the expansion modal (G7E-DR10A) series with (6) input and (4) output and become (14) input and (16) output. The PLC is programmed with Ladder diagram. This develop of a new elevator system is expected to be effective at ideal design in low-rise internal buildings when this elevator type are used
