Select a mounting location
at a convenient viewing height
that’s easily accessible to the
machine operator. Bring power to
the unit (120VAC or 24VDC).
Connect the Cycle Input
The cycle input is a 24 VDC signal
that actuates once per machine
cycle. This can come from an
existing machine control signal;
or if no appropriate signal exists,
from a user-supplied sensor
(proximity, photosensor, current,
accelerometer, etc.)
The SMI 2 uses the cycle input
to count parts. The SMI has
multipliers if the machine makes
>1 part per cycle or requires more
than one cycle to complete a part.
If the machine cycles frequently
enough, the SMI 2 can use the
Cycle input to detect whether the
machine is running or stopped. If
the cycle rate is slow, you will also
need the Run/Idle input.
Connect the Run/Idle Input
When activated, this 24VDC input
tells the SMI that the machine is
running. It is required if the SMI
will not be counting parts, or if
the cycle rate is slow in counting
applications. It’s usually derived
from an existing machine control
signal. It can also come from a user-
supplied sensor if no appropriate
signal exists.
Do you Plan to use the Inhibit
Feature? The inhibit feature gives
the SMI 2 the ability to prevent
the machine from restarting until
a downtime reason is specied.
This important and unique feature
enables ShopFloorConnect to
capture the reason for every
signicant machine stoppage.
Wire the Inhibit Output
to a Machine Interlock
The inhibit output is a dry contact
that opens after a user-specied
period of downtime, and closes
when the operator selects a
downtime reason. It can be
connected to a machine safety
interlock, a stop circuit, or even in
series with the machine’s
start button.

Optional Inputs
Scrap:
Most commonly used for
automated scrap/reject handling
systems (e.g. a diverter arm).
This input also provides a
convenient way to manually
enter scrap/rejects via a normally
open momentary switch.
Setup:
Used to suspend counting
and downtime reason entry
requirement during setup.
Automatic Downtime Inputs:
Four additional inputs
are associated with four
ShopFloorConnect downtime
reasons, when activated, the
associated downtime reason
will be automatically logged
and sent to SFC.
Installation Note
If you plan to use relays to
isolate input signals from the
machine to the SMI 2, we strongly
recommend a good quality 24
VDC power relay with bifurcated
contacts rated for 1V DC, 100
uA minimum (e.g. IDEC RJ22S-
CLD-D24 with Standard socket
or DIN rail base SJ2S-05B).
