The AT5600: what’s new?
The AT5600 integrated test solution for wound components delivers accuracy, speed and reliability without compromise. Building on Voltech’s 30 years of experience in the field of magnetics testing, the AT5600 is an evolution of, and fully compatible with, our AT3600, the industry’s most deployed magnetics tester.
Users upgrading from the field-proven AT3600 and ATi solutions will see immediate benefits: the AT5600 delivers twice the test throughput of the AT3600, without compromising accuracy. Also new to the AT5600 is Ethernet and USB connectivity, while still retaining RS232 connectivity for compatibility with existing installations. And we’ve designed it to provide an easy upgrade path, with no change in fixturing and common test programs across platforms.
This document is designed to provide existing Voltech users with an overview of some of the key improvements and changes we have made, to ensure they get the most from their investment in the AT5600, as quickly and simply as possible.
WILL MY EXISTING FIXTURES WORK ON THE AT5600?
Yes, the AT5600 has been designed to use the same 20-node, true-Kelvin fixturing system as the AT3600 and ATi, so any existing fixtures will work without modification.
The AT5600 also maintains the rear bay area for the AC Interface fixture (see right). This allows you to extend test capability to 600V, 10A and is also directly compatible with the AT3600.
The AT5600 rear panel contains the same 15-way Peripheral Interface Port for use with AC Interface fixtures.
Customers who use the AT3600 or ATi User Port to provide relay switching during test are also supported. The 9-way User Port is now located on the rear of the AT5600, as is the 4mm Earth socket.
WILL MY EXISTING TEST PROGRAMS WORK ON THE AT5600?
Yes, Any existing AT3600 or ATi test program (*.ATP) can be run on the AT5600. The AT5600 uses the same test format and AT Editor software to author test programs
As with moving programs between different AT3600s, you will also have to be sure that your AT5600 has the relevant test options enabled.
Test programs that use features – like diagnostic or audit testing – that are unique to the AT5600 can still be run on the AT3600 or ATi: the unsupported tests will simply be skipped.
Existing AT3600 or ATi users will need to upgrade both the AT Editor and AT Server software to allow them to communicate with the AT5600. The relevant updates can be obtained for free from the downloads page of our website. The new versions of the AT Editor and AT Server software will also continue to support the AT3600 and ATi.
The new versions require Microsoft Windows 7 or above (32-bit or 64-bit). Older versions of the software (for Windows 98 and above) will continue to be available on our website, but these do not support the AT5600.
IMPORTANT UPDATE FOR LEGACY AT3600 +DC1000 USERS
The DC1000 can be easily integrated with the AT series testers to give automated and integrated DC Bias testing, combined with the range of tests provided by the AT.
If you are integrating the DC1000 with any of the high voltage AT tests (IR, HPAC, HPDC, DCRT, ACRT, DCVB & ACBV) it is important that the DC1000 is ONLY connected to nodes used as the LO terminals in these high voltage tests. This will prevent damage to the DC1000.
The AT5600 and AT Editor will check for this in the ATP test program, and warn you if you are attempting to do this.
The AT3600 and old AT Editor did not give this warning, but it is still a valid rule and best practice for the AT3600.
See DC1000A user manual section 6.5.4
You will need to install version V3.53 (or higher) to allow communication with the AT5600 over traditional serial RS232 ports and USB.
For USB you will need to download and install the AT5600 USB drivers, also free from the downloads page.
The new software version is also required if you wish to use the audit and diagnostic test options on the AT5600.
Please un-install any previous versions before installing.
Check after install that your Windows Firewall is not blocking editor.exe
You will need to install version V3.40 (or higher). This will allow communication with the AT5600 over RS232.
This upgrade to the AT Server also allows Ethernet communication between the AT5600 and the AT Server. This will enable control of, and results collection from, multiple AT Series testers via a single AT Server instance, irrespective of the physical mode of communication.
Specifically, the same Server can simultaneously communicate with multiple AT5600s using Ethernet or RS232, and multiple AT3600/ATi testers relying on RS232.
Please un-install any previous versions before installing.
Check after install that your Windows Firewall is not blocking server.exe
WILL I BE ABLE TO UPDATE MY AT5600’S FIRMWARE?
Yes, as with the AT3600 and ATi, firmware updates will be periodically available on our website and will be free to download and install, giving you easy access to improvements in performance and new features as we release them.
Users of existing AT Series products will find the update process familiar: it is performed using the AT Editor software and takes around 15 minutes over USB.
Free firmware upgrades do not change the enabled test options on your unit.
CAN I EXTEND MY AT5600 TEST OPTIONS IN THE FUTURE?
Yes, you can extend the test capabilities of your AT5600 by purchasing more test options at any time.
Adding test functions to your AT5600 couldn’t be easier – unlike customizing the AT3600, there’s now no need to download and install a full, customized firmware update. By entering a secure keycode, unique to your tester, via the AT Editor Software, new test options can be instantly enabled.
ARE THERE OTHER NEW FEATURES OF THE AT5600?
The AT5600 includes audit and diagnostic testing capabilities that significantly improve your quality control processes. It also features enhanced DC bias capabilities.
Audit testing allows you to perform an extended range of tests on a programmed percentage of your production run, without interrupting the manufacturing flow. You can therefore gather extra sample data without incurring extra management time or additional test time.
Diagnostic testing or “test on fail” designates a set of additional tests to be run only if the main test program fails. For example if testing multiple transformers at once, and one transformer fails testing, the diagnostic function can determine which of the multiple transformers has failed
The AT5600 allows up to 1A of DC bias to be applied during inductance or impedance (LSB, LPB and ZB) measurements – more than double the capability of the AT3600. Integration with our DC1000 external bias unit extends this to 25A per DC1000, up to 500A.
ARE THERE OTHER DIFFERENCES BETWEEN THE AT5600 AND AT3600?
The below will give you a quick overview of any major changes you may come across when setting up and running your AT5600 for the first time. We have also changed the way in which the “measure” function is controlled.
One subtle but important change from the AT3600 to the AT5600 is the interpretation of the “Status codes”
Most commonly these are used to indicate tests where the requested voltage or current levels could not be reached under stable conditions.
For example, “0020” indicates “The test signal could not be trimmed to required value; incorrect test parameters for the load.”
AT3600: If, due to mismatched load and signal, the desired signal is not reached the AT3600 will report an error code. However, it will STILL PASS if the measured parameter is within your set limits.
AT5600: the AT5600 will FAIL if the status error code is flagged, I.e. if desired signals not reached, even if the measured parameter is STILL a “PASS”
From feedback we found that customers wanted positive confirmation that the requested signal signals in the program WERE achieved, like a LCR with ALC enabled.
For legacy customer, this can be disabled in the AT5600 (to make behaviour like the AT3600) by setting it in the AT test program
(AT5600 Firmware >7.206, At Editor 3.26.6 or later See user manual 14.5.1.” Disable test failures due to ALC error”)
The form factor and operation of the AT5600 safety interlock connector are identical to that on the AT3600.
The majority of customers use both low and high voltage tests in all their test programs, for this reason the AT5600 is configured so that the safety interlock needs to be closed to run ANY program.
We have found that the vast majority of customers prefer using the AT Editor software for programming and direct control of the unit, as the interface makes the authoring and management of test programs much easier and more intuitive.
For this reason we have not provided front panel measure mode on the AT5600 but we still support the ‘measure button” in the AT Editor dialog boxes for instant measurement and program proofing.
