The Microzed v3.3A elevator controller module contains all the necessary components to control the elevator and to simultaneously insure the protection of the elevator and user against faulty conditions. It can operate in a group of up to 4 elevators. In addition, this module has a userfriendly interface consisting of one 24-characters by 2-lines LCD alphanumeric display and three push buttons to access the different pages, menus and parameters editing (the display is sold separately). All spare outputs are user configurable. The firmware could be upgraded on site. Furthermore, the Microzed v3.3 controller has a serial RS485 port enabling it to be connected to a hand held diagnostic tool (sold separately) or via an interface (sold separately) to the RS232 port of a host computer. Special software, available from S. & A.S. ltd., displays the general status of the elevator and the most recent 99 faults on the computer screen. Group operation for up to four elevators is supported.
