ESW test systems are PC based systems designed for easy start up and operation. The tester, in the automatic mode, is a accept/reject system designed for the production floor. The operator does not interpret any of the test results. All test steps are automatically sequenced and decisions relating to the acceptability of the motor-under-test are made automatically.

To start the test sequence, the operator places the motor onto the tooling, clamps down the motor, connects the motor leads to the connector block and closes the protective cover. Once the cover is closed the selected tests are performed. At the end of the testing, the video monitor will indicate whether or not the motor passes or fails.

If a part fails the video monitor will display "reject" and all the measured data obtained will be displayed. If the part passes all o the tests, "good" is displayed on the video monitor. All measured data and results remain on-screen until the safety slide cover is opened. The results of any test sequence can be printed.

The tester can be set to automatically terminate the test on a rejected part or continue the testing sequence. If it is set to terminate, all measured data obtained up to that point, including the rejected data, is retained on the video monitor for review. If the tester is set to continue testing, all data will be displayed and the rejected data will have an indicator above it, displayed in red. The type of reject is indicated and “REJECT” in red will appear on the video monitor. Opening the safety slide cover will reset the video monitor display. If the part passes all of the tests, “GOOD” is displayed on the video monitor in green. All measured performance data obtained during the tests will remain on the video monitor until the safety slide cover is opened.

The length for each of the test steps can be individually programmed. Total test time will depend on the motor characteristics and your testing specifications. Any of the test steps can be bypassed.

All data will be stored on the systems hard drive by serialized date and time stamp. Total production count data is available during any production run and is displayed in both numbers and percentages. The production counts are tallied and displayed on the computers main screen. The counts are kept for the quantity of motors tested, total passed and total failed. There is also a window showing the number for each type of test that had rejected motors.

The operator may change from one part to another by simply selecting a new part number from the stored parts within the system.The test limits established for that part number are retained, eliminating the need to re-enter test limits every time that part is run.

The Series 6000 testers can automatically set-up test limits on new parts. The operator merely loads the part and sets the tester to the automatic set-up mode. The unknown part is cycled through a full part evaluation sequence and the computer automatically determines the high and low limits. The parameters are then stored in memory. The test limits are automatically set around this stored data, thus making set-up effortless and automatic. If the limits generated by the tester need to be changed, authorized personnel can easily adjust these limits. A set-up fault feature makes it impossible for the operator to set-up or test on a bad part.

A manual mode of operation is provided for set-up or evaluation. The Manual Setup Mode provides a real-time interactive means to evaluate and change test parameters. An operator, using this mode, can optimize each test parameter used by the system for every parameter tested. Dialog menus exist for each test type installed on the system and will automatically come into view as the system sequences through each test step. Confirmation message boxes appear after for each test setup dialog, thus giving the operator an opportunity to save or ignore changes made within each. Test time in the manual mode is indefinite and any of the test steps can be individually selected.
