4.26. F25: MRD POWER FAILED
The MRD power supply is out of specification. Either the supply has been shorted on
the antenna, or an internal DCU5000 supply rail has failed.
4.27. F26: INCLINOMETER POWER FAILED
The inclinometer power supply is out of specification. Either the supply has been
shorted on the antenna, or an internal DCU5000 supply rail has failed.
4.28. F27: FPGA WATCHDOG TRIGGERED
The hardware watchdog in the FPGA has timed out. All motor drive and brake outputs
are disabled. The system will not be able to be driven. Power cycling the DCU5000 will
reset the FPGA watchdog.
This alarm is triggered by a serious software timing error which should never
occur. If seen, please report the occurrence to Advent Communications

temperature of the unit is out of specification, the unit side ventilation grills are blocked,
or the units cooling fan have failed.
4.34. F34: FIN 2 OVER TEMPERATURE
The measured temperature of heatsink fin 2 has exceeded 90°C. The operating
temperature of the unit is out of specification, the unit side ventilation grills are blocked,
or the units cooling fan have failed.
4.35. F35: FIN 3 OVER TEMPERATURE
