The unit is a tabletop structure reproducing a 3 floor lift. As in real installations, several sensors and controls are used for the cabin motion & positioning and the doors opening, such as pushbuttons inside the cabin and at each floor:

• It is possible to manage the unit according to following modes
• Stand-alone operation with internal microprocessor board
• PLC control with 24 Vdc operating voltage and at least 20 digital inputs and 16 digital outputs; PLCs with less I/O cannot allow to develop all the functions
• TTL circuits control with 5 Vdc operating voltage
• Supervision with PC through USB port in LABVIEWenvironment

TECHNICAL SPECIFICATIONS:

• Treated and epoxy-painted steel structure reproducing a3-floor lift.
