The ASIT 5500 will run a series of comprehensive tests on the SIU to verify that it is functioning in compliance with the ATC standard. The ATC standard that defines SIU operation is a joint publication of NEMA, AASHTO and ITE. The tests are subject to the limitations of what is feasible and practical in a simulated testing environment.
The ASIT 5500 will test any SIU that conforms to the ATC 5301 v02.02 Model 2218 SIU standards.
The following functions will be tested. ● Proper supply voltage and current management ● Correct input/output functionality ● Working communications/SIU frames ● Correct Linesync/NRESET/Addressing acknowledgement
The Tester connects to a Windows based computer with a USB connection. The ASIT 5500 Test Manager software controls the Tester and allows the users to run manual or automated tests.
