• Bypass relay is closed
• Rectifier unit ready-to-operate
Red Failure
Group fault,
There is a fault in the rectifier unit, “Fault“ (X91) contact
open:
• 24 V supply voltage < 19 V,
• Line phase failure,
• DC link voltage > 800 V,
• Pre-charging resistor overloaded,
• Heat sink temperature too high,
• Short circuit of the braking resistor
Yellow Chopper active Brake chopper activated
Table 3-1 Operating statuses of the rectifier unit
The fault display is not saved to memory; it appears for only as long as
the fault exists (but for at least 1 sec) and does not need
acknowledgement.
