Operation of the LEDs on control card
22
H1 IGBT gate pulses
H2 IGBT gate pulses
H3 IGBT gate pulses
H4 IGBT gate pulses
H5 +15V
H6 +5V
H7 Remote control unit connected
H8 Data communication
H9 Micro controller operation
H10 Micro controller operation
A001 / LEDS
H1-H4: Indicate the existence of the gate pulses.
H5, H6: Indicate that auxiliary voltages exist (+5V and +15V). If these Leds are not lit when the power source is
switched on, first thing to do is check if control card fuses are OK.
H7, H8: Indicate operation of the auxliary device connection. LED H8 indicates that there is data
communication taking place through the system bus when it is lit. LED H7 indicates that remote control unit is
connected when it is lit.
H9, H10: Indicate state of the microcontroller. In normal situation both leds should be lit.
