Wiring a Scrap Input Switch
The Scrap input, if wired, maintains an automatic count of bad parts, incrementing a scrap counter
each time the input transitions from low (approximately 0 VDC) to high (+24 VDC).
Wire the Scrap input using a dry contact, normally open momentary switch. Connect one wire to
input Pin 3 on connector TB2 and the other wire to Pin 5 on connector TB2 (24 VDC) (see Figure
2-7, page 23).
You must enable the Scrap input in order for the SMI 2 to maintain a count of scrap (for instructions,
see
Configuring the Scrap Input in your user manual and Multipliers and Enable Inputs in the
addendum). If the part being made requires multiple operations, then actuating the scrap input resets
the stroke count to zero, as well as incrementing the scrap count.
NOTICE
You can also wire your scrap handler to the scrap input. Contact Wintriss ShopFloorConnect
Technical Support for more information.
Wiring a Setup Mode Input
The Setup Mode input instructs the SMI 2 to ignore the Run/Idle and Cycle inputs whenever the input
transitions from low (approximately 0 VDC) to high (+24 VDC). This input enables the machine the
SMI 2 is monitoring to be run in a non-production mode, such as during setup or troubleshooting,
without the SMI 2 responding to changes in the running state or to machine cycles. During these non-
production periods, the SMI 2 holds the current machine state, including the downtime reason if one
is in effect, and does not count parts.
The Setup Mode input should be connected to a switch or output from the machine control that
actuates (i.e., goes to +24 VDC) whenever the machine is not in production mode, such as a setup or
programming switch or a switch that places the machine in Jog or Inch mode.
To wire a Setup Mode input, connect one wire to input Pin 4 on connector TB2 and the other wire to
Pin 5 on connector TB2 (see Figure 2-7, page 23).
Wiring Automatic Downtime Inputs
NOTICE
These automatic downtime inputs on TB4 are factory set as PNP.
To change all of them to NPN, move the jumper on TB3 pin 3 to +24VDC.
Four inputs on SMI 2 provide automatic downtime logging. When the monitored machine transitions
from Running to Idle and one of these inputs is ON, SMI 2 automatically uses the assigned downtime
reason. You can use these inputs to monitor ancillary equipment that could stop your production line.
The automatic downtime inputs (TB4 inputs 1-4) are associated with four downtime reasons, 29 – 32,
respectively. Create these downtime reasons in SFC the same way as you create the others.
