SWITCH SW2

This switch is factory set as shown
in diagram i.e. machine start and
standard OMMs.
AUTO START selection causes the
system to send a start signal once
every second and does not require
a CNC machine control input.
AUTO START should only be used
when no output from the machine
control is available. If this mode
is selected, care should be taken
to ensure system signals are not
receivable from probing systems
on other machines.
To initiate a MACHINE START signal,
an input of between 4,25 V at 1 mA
and 30 V at 10 mA is required
between terminals 21(+) and 22 (-).
(TTL compatible when connected
between +5 V and TTL output).
This is an isolated input.
Minimum pulse width is 1 ms.
Maximum pulse width is 150 ms.
The manual start switch SW1 is
disabled for the duration of the
MACHINE START input signal.
