Connecting the UCC MMI to a CMM
The controller monitors the input and will signal to the software if it goes open circuit or high. If not required the input should be connected to the 24 V return line. See 'Generic UCC I/O connector details'.
NOTE: The polarity of this input can be inverted by the UCCassist set up utility. The default condition is a normally closed circuit, opening on the event.
Switching polarity can be adjusted in the software or by using hardware. In UCCassist-2 all inputs can have polarity set to normally open or normally closed.
Pins 13, 14 and 19 - 36 are switchable inputs that are normally open and need to be set to normally closed.
There are two methods for doing this:
- Connect each pin to pin 37.
- Switch the polarity of inputs using UCCassist-2 commissioning software.
