5 Troubleshooting
1217 Error: Matching box fan failure.
The number of revolutions of the matching box cooling fan went below the
limit.
Check the number of revolutions of the matching box cooling fan. The cooling
fan, cooling fan wiring or MNBXY board is abnormal.
1218 Error: Plasma was shut off. (Plasma RF Monitor).
The plasma has extinguished (In Analysis mode or during maintenance).
Check the argon gas line pressure and flow rate. The following causes are
inferred.
• The installation of the torch, bonnet, and shield plate is faulty.
• The Argon gas is not supplied or there is a leak in the gas line.
• The air is mixed with argon gas.
• The limits of the tuning parameters for the RF Matching are inappropriate.
• The Plasma RF cable came off or the cables are defective.
• Malfunction of the Shunt condenser and Series condenser (A faulty XYZMN
Board is also probable).
• Power cable to the plasma RF generator came off.
• Faulty plasma RF generator.
• Faulty DC Power Supply.
• Faulty plasma sensor optical cable
1219* Error: Plasma was shut off during vacuum (IF) ON.
The plasma has extinguished (When the instrument is changing from Standby
Mode to Analysis Mode).
