    The UCClite-2 has the following controller switch inputs, please refer to section 6.8.3 for details: Pins 13 and 14 are the two uncommitted inputs available on the UCClite-2 I/O connector, all other inputs have dedicated functions. The UCCite-2 does not directly read these inputs, they can be read by the application software package via command 279 ‘Read from controller ports’.

    6.8.10 Limit switches The UCClite-2 will use these input signals (pins 25 to 36) to stop the CMM as programmed by the host computer (See the UCC programmer’s guide, command number 311). All outer limit switches have to be closed before the CMM drives can be engaged. Operation of these switches is interpreted as a fatal fault.
