SYSTEM OPERATION
OMM, MI 12 and O-M-I LED's continuously indicate system status during operation.
STAND-BY MODE/OPERATING MODE
To conserve battery life, the LTO2 is held in the
stand-by mode, until a switch-on signal is sent from
the CNC control, via the OMM + MI 12 or O-M-I.
The LTO2 is only active during the operating mode.
LTO2 SWITCH-ON
To initiate an inspection routine, the probe is
indexed to the tool cutting position, and switch-on
is commanded.
SWITCH-ON OPTIONS
1.
Machine Start - Software M code command.
2.
MI 12 interface manual start (OMM version only).
3.
Auto Start - start signal at one second intervals.
The MI 12 and O-M-I are factory set to
machine start.
LTO2-OMP SWITCH-OFF
(TIME-OUT OPTIONS)
A timer switches the OMP off, after a selected time
interval known as time out. Four time-out options
are available -
5 sec, 9 sec, 33 sec or 134 sec.
The LTO2 is factory set to time-out after 33 sec.
During the operating mode each probe contact
causes the timer to reset-on for a further 33 sec
(factory set) or 134 sec (optional), if no further
probe contacts are made, the LTO2 reverts
to stand-by mode after 33 sec or 134 sec.
(33 sec or 134 sec reset times apply to 5sec and
9 sec time out options if the probe is triggered).
Note:
A start signal will also reset the timer.
DEBOUNCE TIME
When the probe switches off, there is a delay
before it can be switched back on again.
This is known as the debounce time.
Two debounce time options are available
-
5 sec or 9 sec
.
The debounce time is factory set to 5 sec.
