Description
The multiprogrammable logic boards of CTA are made on the basis of a microcomputer monochip of last generation and constructed with elements of solid state. The programming of these boards is made through a communication channel type RS232C connected to the console of programming or a computer compatible type PC.
The access to the database of programming and registry of failures is made by means of secret code of four digits user defined (initial code " 1234 ").
All the codes of failures are reflected in display of the board.
In order to transform a system into dúplex it is only necessary to unite the two controllers with a cable of communications RS232C. For systems triplex, cuádruplex, etc., it is necessary to install a CM5. The CM5 also controls the communication via modem, and along with the program cta24h, can control and manage the installation from an installed compatible PC in any place with telephone line. All the controllers have preinstallation to the system cta24h.
All the boards are united by means of plug-in connectors, simplifying the substitution in case of failure.
The Input Boards of threads of pulsers has pulsers of test to the verification of the operation of the equipment with no need to make discomforts bridges.
The Output Boards make the union between the logical drive and the elements of power of the elevator. The connection with these elements (equipment tractor, levy, brake, etc.) and series of securities is made by means of bornas of pressure mounted on profile DIN35.
All the equipment can be provided in premounted systems.
