Nirvana Systems Ltd supplies technical expertise and offers solutions to the elevator industry on a contract basis. We have assisted most of the elevator companies in New Zealand.
We have many years experience of replacing failed and obsolete PLC equipment.
This invariably involves writing custom software to suit the installation as copies of the original software are usually not available.
We can provide analysis of existing PLC installations with regard to safety, performance and reliability.
We can modify the software and/or hardware on most PLC installations to upgrade and enhance features and performance.
We have designed a PLC based elevator controller.
We believe the Nirvana Elevator Controller is the safest, most easily maintained, most feature rich and most reliable PLC based controller available.
The Nirvana Elevator Controller is designed to be the ultimate elevator controller, flexible, intuitive and easily maintained by any elevator technician.
The Nirvana Elevator Controller has been installed on many sites around New Zealand including a ten storey hydraulic elevator, a hydraulic elevator on a ship and duplex traction elevators in international hotels.
We have developed PLC based solid state replacements for various faulty and obsolete elevator equipment. These include:
• Mechanical impulse selectors.
• Electronic floor selector boards.
• Replacement of an Otis Electronic Modular Overlay (EMO) providing traffic control on a group of
three medium rise elevators.
• Designing a traffic control system to replace a failed Fiam electronic microprocessor system.
We have designed a high speed datalogger which can capture and record events at 1/100th of a second on up to 48 simultaneous inputs .
It has 9 programmable triggers to flag pre-specified complex events.
The datalogger allows indepth analysis of performance and fault events.
We have designed duplex and triplex traffic control systems for groups of elevators.
