EMI Porta Elevator Selector Position Control Circuit Board - Ver. 5

This SELM5 Selector PCB serves as the electronic interface within an elevator selector system, supporting continuous determination of the elevator car’s position as it travels through the hoistway. Position information is communicated to the microprocessor-based control system so the elevator can coordinate operational points along its travel. The board supports the selector functions used to establish floor locations, slowdown points, stopping positions, and door zones. This position feedback allows the control system to coordinate car movement with programmed landing locations and leveling requirements. It is intended for EMI Porta selector applications used in legacy modernization, existing-system retrofit, and new elevator installations and is not specific to an elevator brand or model. Component type: Elevator selector printed circuit board SELM5 Version 5 System type: Microprocessor-based elevator control Primary function: Hoistway car-position processing Position functions: Floor location and stopping reference Travel functions: Slowdown point coordination Landing functions: Door-zone and leveling position reference System interface: Selector and elevator controller Application: Modernization, retrofit, and new installations Selector electronics should be installed and commissioned by qualified elevator personnel in accordance with applicable codes, system requirements, and established industry practices. Proper installation and alignment of the complete selector system support consistent position detection and reliable elevator operation.
