H1 LED: FANS, LED is on, when fans aren´t rotating and vice versa. If fans never rotate,
check the fan supply voltage from connector X, between pins 3 - 8 and 6 - 9 (24 VDC).
H2 LED: BUS POWER SUPPLY, while the LED is on, it indicates th e50 VDC voltage
present in the bus connection. If the LED is off, then check the voltage from connector X4
between pins 6 - 8. Check the fuse F002, diode bridge G004 and auxiliary transformer
T002.
H3 LED: SERIAL COMMUNICATION, while the LED is on, it indicates the presence of
serial communication. If the H2 is on, but H3 is off, most likely there is something wrong
with the program on the control card.
H4 LED: REMOTE CONTROLLER, while the LED is on, it indicates a connected remote
controller R10 or R20.
H5 LED: GATE PULSES, while the LED is on, it indicates the presence of the gate pulses.
LED´s brightness depends on pulse width and the power under load.
H6 LED: X5- AND X6-CONNECTORS ARE CROSS-CONNECTED, while on, the LED
indicates the cross-connection of IGBT gate connectors X5 and X6. Shut the machine down
and connect the gates correctly!
H7/H8: GATE PULSES: while on, the LEDs indicate the presence of gate pulses. Brightness
of the LEDs depends on pulse width. If H5 is on, but H67 and H8 are off, then the gate
circuit is damaged (pulse transformer, FETs etc..
