Intel-Lift G3 Master Controller Board & Call / Send Station



The new Inteli-Lift G3 system is an extreme upgrade to the Gen II system.

This is being developed by seasoned electronic engineers using CPLD solid state relay logic technology.  The system is being designed by our full time electrical engineer Roberto Calderon.  Roberto has an impressive back ground with a Bachelors of Applied Sciences Degree in Electrical Engineering Technology in1997. He has built CPLD and microprocessor machine control systems for the US Military, Intel, Hewlett Packard and more.  The system is using a Xilinx CPLD chip.  This is a schematic based control program that opens and closes gates for the inputs and outputs on the chip.  There is NO software in the system.  Software driven microcontroller systems have proven over time to all posses hidden bugs and issues.  We are exited to be moving away from software driven control systems.  The Xilinx driven systems are currently being used in automotive, 5G wireless, data centers, aerospace and defense, broadcast & A/V, consumer, industrial, medical & science, wireless infrastructure and much more.  Todays Xilinx chips have a 20+ year program retention, assuring long term reliability and consistent operation.


The new Inteli-Lift G3 master controller board will be easy to operate and understand by the installing technicians.  The system will have a manual mode operation on the master board with constant pressure activation of the motor assisting in initial installation as well as future wire rope changes.  The call send digital stations will also act as a constant pressure manual operation run bug in this mode.  There will be a rotary dial with 10 positions for “do not interrupt” that will disable the call / send stations for 0-77 seconds.  This will allow the users to pull the goods from the car before the unit is called to another floor.  There will be LED indicators for all safety circuits, landing limit switches and doors.  The system will be available for up to 10 levels including a basement feature with a front and rear door at each level.

Notable changes to the G3 platform:

  • Separate communications and power via cat 5 and a 4/18 conductor line.
  • 4 /18 gauge conductor will come out of the master to each station board and carry 24vdc and run the safety circuits and doors
  • Safeties on each station board are now a hardware dip switch selection (not software as with the Gen II system)
  • Floor selection is now done on the station board via a rotary dial with positions 0-9, 0 will be designate “b” for basement
  • All components on the printed circuit boards have incredibly robust values for long term durability

UL Certified commercial dumbwaiter systems with LED digital floor call stations showing current floor, in use, direction of travel and arrival buzzer.  The only digital call stations for commercial dumbwaiters in the USA.



Introducing The New CPLD Solid State Relay Logic Six Stop Controls:

Here is a comparison set of pictures, first is the new three stop CPLD Controller, followed by the old school relay logic systems we will be replacing.  The CPLD system is now in shipping and available for up to six floors with a front and rear door at each level.


CPLD Solid State Relay Logic Designed for 20+ year Life Cycle

No software, the CPLD is a technology used by the military to deliver a rock solid control system using a Xilinx chip and a schematic based logic program.  These CPLD boards are designed to run for 20+ years.  Our CPLD systems (complex programmable logic device) will be a control choice on any dumbwaiter system we offerUp to six floors with a front and rear door option at each level.  This will expand the capabilities of the Econo-Lift® system up to four floors.

LED Monitored Safeties, Manual Movement & Non Interrupt Time Delay

The LED’s monitor the safety circuits of the system including doors, gates, slack cable, final limits, the VFD drive and redundant contactors BK for the motor brake system, M1 and M2 for redundant motor monitoring including phase reversal protection.  The up / down buttons are for manual movement of the dumbwaiter during installation.  You can also connect any call / send station and use level 1 button for down movement and level 2 button for up movement.  This is a temporary constant pressure run system.  You must use the “Safe Override” slide switch for this feature.  The system will not run in automatic mode in this state.  Also there is a selectable non interrupt time delay rotary switch.  This will keep the system from being called for a selectable amount of time for 0 – 77 seconds (custom timing is available).

Commercial 90 minute fire rated slide up and bi-parting door systems will feature” i3″ Innovation Industries Inc. Call / Send Fixtures with “In Use” and “Car Here” Lights.
