6. On Nut #5 the operator inadvertently jerks the wrench. Since there is no green Accept LED
lit and the count did not advance, he knows he must retorque the fastener. He loosens the
fastener, then properly retorques it. The green Accept LED lights and the count advances
from 2 to 3 on the LED Panel.
7. The operator then moves to the last fastener on the assembly. The FM Switch Wrench is
used properly, applying the proper torque and earning the operator a green Accept LED, a
double-beep from the beeper to indicate the batch of fasteners is completed, and a reset to 0
on the LED Panel in preparation for the next assembly. A Batch Accept signal is sent to the
PLC Connector to signal completion of the assembly to the PLC.
In this second example, the operator changed the parameter in use by rotating the Parameter
Select Switch. The PLC had been programmed to count the batch accept signals coming from
the PTV, and advance the line only on the even numbered signals.
The change in active parameter from A to B could have been accomplished via PLC command
instead. The batch accept from Parameter A could have triggered the command to switch to
Parameter B.
The means by which the signals to the PLC are used to control the line are limited only by the
PLC hardware and the desire of the PLC programmer.
Please note that S/R does not perform PLC programming. Our expertise is in torque application
and measurement. We provide the signals at the connector, and leave their application to the
ingenuity of our customers.
