Repair and Troubleshooting Technical Alarms Check
0x00000200 AIR flow leakage.
1 Select [Setup]?[Service]?[Data Monitors]?[Component]?[FCS].
2. Check the value of "AIR Limb Flow". Make sure that this value exceeds
0.07LPM. Then disconnect AIR supply (eject BFCS and open needle valve in AIR
limb to exhaust the excess gas to prevent gas inside the pipeline from affecting
the leak test result). After restarting the machine, if this alarm is still triggered, it
is considered that Sensirion flow sensor in AIR limb is faulty. Replace this flow
sensor.
3. If the fault disappears after AIR supply is disconnected, it can be considered
that AIR Prop Valve cannot be closed. Consider to replace AIR Prop Valve and
return the faulty flow sensor or proportional valve to R&D.
0x00000400 N2O flow leakage.
1 Select [Setup]?[Service]?[Data Monitors]?[Component]?[FCS].
2. Check the value of "N2O Limb Flow". Make sure that this value exceeds
0.07LPM. Then disconnect N2O supply (eject BFCS and open needle valve in
N2O limb to exhaust the excess gas to prevent gas inside the pipeline from
affecting the leak test result). After restarting the machine, if this alarm is still
triggered, it is considered that Sensirion flow sensor in N2O limb is faulty.
Replace this flow sensor.
3. If the fault disappears after N2O supply is disconnected, it can be considered
that N2O Prop Valve cannot be closed. Consider to replace N2O Prop Valve and
return the faulty flow sensor or proportional valve to R&D.
0x00000800
Startup zero reading
error.
1. Restart the machine.
2. If the problem still persists, it belongs to hardware failure. It may be 0632 EFCS
VCM board PCBA failure. Replace with a new board and return the faulty board
to R&D.
0x00001000 FPGA configuration error.
