DC IGBT, test and fitting instructions
DTE 200 / DTE 255
Make all measurements listed below with the machine disconnected from the mains.
Generally, if the IGBT module has burnt out, one or both of the high--speed fuses on the
protection boards will also have blown. To check the fuses, disconnect connector XI from
circuit board AP01. Measure as shown in the diagram below. If the fu ses are healthy the
meter will display 10kΩ..
Checking gate fuses
To make a complete check of the IGBT module, remove the screws at C1, E2 and C2E1, then
remove circuit board AP02. Use a multimeter in diode test position to measure as shown in
the diagram below.
Warning: The IGBT module is sensitive t o ESD.
