Preliminary information
4
A workpiece set-up and inspection probe is, in
effect, another tool in the system. A probe cycle
may be included at any stage of the machining
process.
Signals are transmitted between the probe and
the machine’s control, via the OMI or alternatively
the OMM + MI 12. Interface units convert probe
signals into an acceptable form for the machine’s
control.

Twin OMM mounting
On large machine tools it is possible to provide
greater reception coverage by mounting two
OMMs connected to a single MI 12.
Remote indicator
The MI 12 interface contains an LED and acoustic
indicator. When the probe is triggered the LED
will change state and a beep is emitted.
If the MI 12 is hidden from the operator, a remote
lamp or bleeper may be placed in a position where
it is easily seen or heard.
