An internal communication
failure occurred between the
LCD/control PCB and the
DSP PCB.
This fault code does not stop the system from
operating. The system can continue to cut, but
Hypertherm recommends that you find the
cause of the problem first because the controls
on the front panel are not available. Do the
following:
• Set the power switch on the plasma power
supply to OFF (O). Wait until all the
amperage LEDs on the SmartSYNC hand
torch go off. (Or, wait approximately
1 minute.) Set the power switch to ON (I).
• Make sure that the ribbon cable between
the LCD/control PCB and the DSP PCB
inside the plasma power supply is fully
connected to both PCBs.
• If the problem continues, replace the ribbon
cable. Refer to Powermax65/85 SYNC
Service Parts and Procedures Guide
(810440) or Powermax105 SYNC Service
Parts and Procedures Guide (810450).
If the system is in basic mode when the fault
occurs, the system automatically adjusts the
following settings to prevent damage to the
cartridge:
• It sets the output current to 45 A.
• It sets the operating mode to Cut mode.
• It sets the output gas pressure to cut
pressure. The system adjusts the pressure
even if the system is in manual gas pressure
mode when the fault occurred.
The system keeps these settings until you install
a new cartridge, do a cold restart, or change the
settings from the CNC (if applicable). If the
system stays in this fault condition after a cold
restart, it goes back to smart mode and sets the
output current (A), operating mode, and output
gas pressure to go with the cartridge that is
installed on the SmartSYNC torch. For more
information on smart mode and basic mode,
refer to page 155.
