The purpose of testing wire harnesses is to make sure that only good product is shipped to customers. Wire harness manufacturers have developed a variety of methods and schemes to ensure that only good product goes out the door. Dynalab designed the NX System to be adaptable to a variety of these methods to help manufacturers control the quality of their product.
Fixture Clamp Activation
Some manufacturers employ solenoid-actuated clamps on their test fixtures to prevent removal of the wire harness from the fixture until the test has completed. The NX Tester, equipped with a control port module, can be programmed to automatically release a fixture clamp only when a wire harness passes all tests.
Connector Stamp Activation
Some manufacturers employ a connector stamp to mark good wire harnesses. The NX Tester, equipped with a control port module, can be programmed to automatically activate a connector stamp only when a wire harness passes all tests.
The NX Tester can be programmed to print a label every time a wire harness passes
all tests. This provides an excellent quality control mechanism to ensure that
only good wire harnesses receive labels. The NX System has been designed to support
printers from Zebra and Eltron.
The NX Tester can be programmed to enter an Alarm Mode whenever a wire harness has been removed from the fixture before testing has completed. The Alarm Mode aborts the test, sounds a continuous alarm, and displays a message indicating early removal of the wire harness. This behavior continues until an authorized person with a Supervisor Key disables the Alarm Mode. The Alarm Mode cannot be disabled in any other way. This provides an excellent method of ensuring that all wire harnesses are completely tested.
The NX Tester can be programmed so that only authorized personnel with a Supervisor Key may abort a test in progress.
