RMI-Q basics
Common start (level mode)
In common start (level mode), machine start
inputs P2 and P3 are used to select the probe
and machine start input P1 is used to start the
selected probe. All inputs are level.

Machine start input active.
When P1 is off, all probes are off.
When P1 is active, the selected probe will be on.
NOTES:
Machine start input P4 is not used in common
start.
Any change to the probe selection inputs P2 and
P3 whilst the probe is operating will result in an
error condition.
Level start mode is not compatible with RMPs
configured for radio M code on/time out off.
Common start (pulsed mode)
In common start (pulsed mode), machine start
inputs P2 and P3 are level inputs used to select
the probe. Machine start input P1 is a pulsed input
used to start the selected probe.

NOTES:
Machine start input P4 is not used in common
start.
Only the probe start signal P1 will be pulsed and
will change the probe status between on and off.
The probe selection inputs P2 and P3 will be level.
Seated start on
When seated start on is selected, the RMI-Q will
not drop the error line until the RMP has become
seated. This provides compatibility with controllers
that regard the RMP to be in error if it is started in
a triggered condition.
0.5 second turn on
0.5 second turn on provides compatibility with
controllers that have quicker response times, to
give a reduced probing cycle time. Standard turn
on time is 1 second. These turn on times apply to
radio M code on only.
