AST2000 Specifications

 

Overview:

There are many cable and harness test applications that involve complex program flow to integrate manual or machine operations. Switch operation, relay energising, mechanical tests, functional tests, marking and voiding are examples where conventional (stand-alone) testers are difficult to implement. The AST 2000 is designed for machine integration making automation of complex operations straightforward offering faster, more cost effective test solutions. The AST 2000 has found wide application in end-of-line harness test in high volume environments such as automotive and consumer electronics manufacturing but is equally suited to any task where electrical test and computer control are essential.

24 volt logic

The heart of AST 2000 is a powerful PLC. By using 24 volts as the test level, all wiring continuity and pattern tests communicate directly with the controller enabling test to interact with any logical conditionally. The test program can be preceded by automated or manual data entry such as bar codes, names, dates, batch numbers etc. and can be followed by automated action conditional on test events such as Pass or Fail or a when any given pattern is recognised. The PLC enables a range of accessory equipment to be switched in such as markers, specific function tests, encapsulations, colour measurement, guillotines, punches etc. at any time within the program flow.

Programming

The AST 2000 is an application specific tester and is programmed to perform designed functions. This level of programming is achieved off-line and all requirements are designed in at this stage. Two other levels are provided: The operator level enables basic start and input functions and the supervisor level, accessed by key, provides programmed access for decision making and troubleshooting

Typical application

Cost saving and increased test speed is a common justification for AST 2000 by manufacturers of high density male connectors. Automatic machines load headers with contacts whose number and position is customer specific. The test ensures exact pinning to the customer specification. Defective connectors are automatically identified and removed. The AST 2000 is programmed by using a known good sample and by completing simple dialogues within the Windows display. The number of connectors that will be tested simultaneously is always a maximum dependent on the total number of test pins available. Testing 128 test points takes 50 ms. The automation advantage of AST-2000 typically increases connector throughput by 500%.
