3 Interface unit
HSI interface unit
HSI-C interface unit
WARNING: Before installing the interface unit,
ensure that the machine is safe to work on. Switch
off machine power when working in the control
cabinet.
The APCA-45 requires use of the HSI or HSI-C
interface unit.
The HSI-C has additional functionality compared
to the HSI that enables the user to select a
suitable level of immunity to false triggering for
the connected APCA-45 unit, caused by machine
vibrations or accelerations. The HSI-C can also
respond to a config override input that switches
the probe to the highest level of immunity to
false triggering when manoeuvring to a measure
position at high speed.
The interface unit should be installed in the CNC
control cabinet. Where possible, locate the unit
away from potential sources of interference such
as transformers and motor controllers.
