Cables. 

When the driver detects IGBT short circuit or VGE drops bellow acceptable value the controlled IGBT will be switched off safetly and a fault will be reported. The event is additionally indicated by lighting diode D1. Voltage on X1.3 changes from VDC level to around 1V and diode in transmitter XT1 is switched on. Regardless PWM signals the IGBT stays off and fault is indicated. In order to get driver operating again the driver must be reseted in one of three possible ways: • Pressing switch S1 • Apply voltage with a positive edge greater than 10V (max. VDC) to X1.5 • Keeping PWM signals on “low” level for more than 60ms Keeping the switch S1 pressed long time may lead to permanent IGBT destruction when the reason for short circuit or low VGE remains. Reseting procedure is needed always after fault indication.
