1300 Error: QP fan malfunction
The number of revolutions of the QP driver unit cooling fan went below the
limit.
Check the number of the revolutions of the QP driver unit cooling fan. Either
the cooling fan, cooling fan wiring, or the QP driver board is abnormal.
1301 Error: QP control (Feedback circuit) malfunction.
The V voltage of the QP cannot be controlled.
Check the V voltage of the QP and QP- RF forward power, reflected RF power.
The following causes are inferred.
• S24V is not supplied (Cover is open).
• QP- related cabling came off.
• QP rod, or QP- related wiring (including the vacuum chamber) causes a
short in other metallic parts.
• QP Matching frequency is not appropriate.
• Faulty QF tank board (QP tank coil burn).
• Either the QP RF amp board, QP pickup board or QP driver board is faulty.
• Faulty DC Power Supply.
1302 Error: +600V power supply voltage is too low.
The voltage of the DC/DC converter (+600V) of the QP driver unit went below
the limit.
Check the QP driver +600V power voltage. The following causes are inferred.
Note: To restart, turn off the plasma once.
• S24V is not supplied (Cover is open).
• QP- related cabling came off.
• QP rod, or QP- related wiring (including the vacuum chamber) causes a
short in other metallic parts.
• Either the QP power board or QP driver board is faulty.
1303 Error: +600V power supply voltage is too high.
The voltage of the DC/DC converter (+600V) of the QP driver unit exceeds the
limit.
Check the QP driver +600V power voltage. Either the QP power board or the QP
driver board may be faulty.
1304 Error: - 600V power supply voltage is too low.
The voltage of the DC/DC converter (- 600 V) of the QP driver unit dent below
the limit.
Check the QP driver - 600 V power voltage. The following causes are inferred.
Note: To restart, turn off the plasma once.
• S24V is not supplied (Cover is open).
• QP- related cabling came off.
