This requires the use of two different FM Switch Wrenches, each set to a different torque. It also
uses the multiple parameter capability of the Generation II PTV-FM. This is not done just
because of the two wrenches required, but also because the soft joint requires a different time to
work properly. The soft joint requires more time in the clicked position to torque the joint proper-
ly. The definition of “properly” has changed from that of the front joint.
The first FM Switch Wrench will be preset for the torque for Nuts #1 & #2, and the times and
other components of the parameter will be programmed into the Generation II as Parameter 1.
The second FM Switch Wrench will be preset to the torque for Nuts #3 - #6, and the times and
other components of the parameter will be programmed into the Generation II as Parameter 2.
Again, all the operator needs to do is follow the correct sequence using the correct tools. A color
coding can be applied to the wrenches (colored tape or a daub of paint) as additional visual cues
for the operator during assembly.
In operation, the steps and feedback for each would be as follows:
1. The assembly moves into the assembly station. The operator picks up Switch Wrench #1,
and torques the first nut properly. The operator receives a green Accept LED and the count
on the LED Panel advances from 0 to 1.
2. The operator then uses the same torque wrench to tighten the second fastener in the
sequence, and performs the second tightening properly. The operator again receives a green
Accept LED on the PTV, a double beep is sounded to signal the completion of the batch, a
batch accept signal is sent to the PLC Connector, and the count is reset to 0 for this parame-
ter.
3. The operator returns Switch Wrench #1 to the workbench, and obtains Switch Wrench #2.
He then rotates the Parameter Selector from A to B. Since no fasteners have been tightened
for this parameter, the count displayed on the LED Panel is 0.
4. The operator uses Switch Wrench #2 to tighten Nut #3. Since he performs the operation
properly, a green Accept LED is lit and the count advances from 0 to 1.
5. The Supervisor comes up and asks the operator a question. A three-minute discussion
ensues before the operator returns to the task. He need only look at the PTV-FM to see the
number of fasteners correctly tightened, and knows to work on Nut #4. He performs this task
properly, and again receives a green Accept LED, and the count advances from 1 to 2.
