Step By Step Test Instructions:

• Includes Pictures and directions

• Dated • Approved by

Management

Overall: Change Tolerance on measurements from 10% to 3-5% Three motors will need to be tested: 170W, 220W, 360W

◦ All have the same housing Need to check every unit for errors Consider techniques for a locking mechanism to lock the unit in place if it fails. Need to check that the unit is in place.

◦ Using torque in/out relationship is good, instead of a device like a proximity sensor Need to be able to track what operator is using the machine

◦ Each employee has ID with barcode that they use to clock in and out Maval can handle any manufacturing of components needed Labels: Only create label for good units Same serial number should be used for motor and control module No need to keep data from failed units Process to run test: Scan elites S/N Scan test specs (170W,220W,360W) Run To Re-run good parts:

◦ Have option for re-run◦ Store re-run and original run data in the same folder

Notes From the Visit

Concepts/Operation: The monitor mounted in the background or on a swing-arm would be good Scan to run instead of button No need for external red/green light, on screen is fine They preferred the first of the two concepts No need to have a complete table if its not necessary for functioning, no extra room for

miscellaneous items to be left on table! They do not want to use computer mouse and buttons often Need to be able to run one stand and put the other in queue Need to have option for the case that the barcode does not read   Action Items: Send Maval summary of labview (Functions vs Cost) Send Maval required computer specifications Dale Lumby to send contact information for purchasing and Rob, Dave, Jim, and Mark Dale to send what label printer and scanner they want to use Additional Visit Notes: 360W Motor using up to 52 Amps Input side of motor has all the potential mounting locations

◦ Motor may have to be underneath the unit
