E2209 low ignition current error

Issue 

Plasma won't stay lit, E2209 low ignition current error

Previous Steps Taken:

• Replaced RF MK2
• Tried another RF PCB
• Replaced the I/O board for interlock issues
• Replaced the whole MK2 RFG.
• Reviewed all interlocks and confirmed settings

Environment

• iCAP 6500 Radial
• iCAP 6500 Dual
• iCAP 6300 Radial
• iCAP 6200 Dual
• iCAP 6300 Dual

Resolution

Non-descriptive plasma or RF errors could be caused by any intermittent interlock, for example the chiller or even the pump tubing coming from the sample introduction. This could also indicate a bad RF supply, but it’s more likely to be caused by sample introduction, gas quality, extraction or one of the interlocks.

Moving the external RF interconnect that came with the MK2 upgrade vauses the operation to come and go. Attempts to repair cable connections did not help.

The torch mount interlock switch may be intermittent due to corrosion. Can get more consistent plasma failure or lighting by how firmly the torch base is rotated to its stop.

The issue was resolved by dismounting and removing linear cam and cleaning for free movement. May also need to replace the switch (p/n 430117223171: Switch, Door / Torch Microswitch).

The torch mount interlock switch was bad (very hard to see and access), the outside lug was ready to break off from corrosion, replaced the switch and it's working good. As far as the error code goes, it said plasma went out unexpectedly E9000. It did not pick up the torch being out by a specific fault.

The RF coil is not screwed in completely or the RF coil will need to be replaced (p/n 842315550391)
