The RMP3 transmission module can be
switched on and off by a number of different
methods:
All options are selectable on the MI16 interface,
and programmed into the RMP3 from the MI16
- see page 26.
TIME OUT PERIOD
This is selectable to 30 sec (± 1sec) or 180 sec
(± 1sec). With prototype RMP3's or if a Mk1 MI16
is used for programming, then the time out will be
180 sec (± 1sec)

MP18-S PROBE WITH SHANK SWITCH
The MP18-S, is supplied with a modified shank
incorporating a shank switch.
Switch on occurs when the shank is inserted into
the machine spindle causing the switch to
depress and switch the probe on.
The probe switches off when the probe is
MODES OF OPERATION
MP18 PROBE SWITCH ON / SWITCH OFF OPTIONS
Note for M code probe activation, an OM16 is required.
SWITCH ON METHOD
A machine M code causes the OM16
to send an optical signal to the RMP3,
which switches it on.
The machine M code causes the
OM16 to send an optical signal to
the RMP3, which switches it on.
The machine spindle is rotated at
500 rev/min (± 50 rev/min), for a
minimum of 1 sec to ensure reliable
switch on.
The machine spindle is rotated at
500 rev/min (± 50 rev/min), for a
minimum of 1 sec to ensure reliable
switch on.
When a particular option has been selected,
all other options are disabled.
A standard RMP3 allows any of the options to be
selected except the shank switch method, which
requires a dedicated shank.
DEBOUNCE PERIOD
After the probe is switched on it cannot be
switched off again until a period of 2 seconds
has elapsed. Similarly, after switch off, the
probe cannot be switched on again until
2 seconds has elapsed.
SWITCH OFF METHOD
A machine M code causes the OM16
to send an optical signal to the
RMP3, which switches it off.
The RMP3 will switch off once the
timeout period elapses since the last
probe trigger, or since the RMP3 was
last switched on (whichever was
later).
The machine spindle is rotated at 500
rev/min (± 50 rev/min), for a minimum
of 1 sec to ensure reliable switch off.
The RMP3 will switch off once the
timeout period elapses since the last
probe trigger, or since the RMP3 was
last switched on (whichever was
later).
removed from the machine spindle.
The shank switch option is selected from the
MI16 machine interface - see page 26.
TAKE CARE
Ensure that the shank switch is not depressed
when the probe is stored in the machine tool
carousel.
