7-1-2. Troubleshooting related to the matching box 

 

Table 7-2. Matching box related troubleshooting list 

 

No.

 

Trouble symptom

 

Cause

 

Corrective action

 

1

 

Matching cannot be 
achieved at the usual 
matching point after the 
power is turned on.

 

Load conditions differ from 
previous conditions.

 

Check the gas pressure, 
substrate, etc.

 

Wiring in matching box is 
disconnected.

 

Check the wiring.

 

Wiring from matching box to load 
is grounded.

 

Check for traces of discharge on 
the variable capacitors and the 
wiring in matching box.

 

2

 

Reflected power (REF:Pr) 
does not decrease.

 

Insufficient matching adjustment

 

See "5-3 Matching adjustment" 
and adjust matching.

 

Not discharging.

 

Check the discharge conditions 
like gas pressure, etc.

 

3

 

Variable capacitors not 
operating in manual mode.

 

Auto matching controller problems

 

Contact ULVAC.

 

Mechanical problems

 

Check the coupling connecting the 
variable capacitors and motor to 
see if it slides.

 

Electrical problems

 

Contact ULVAC.

 

Cable break or poor connector 
contact

 

Retighten the connector screws. 
Purchase a new cable if broken.

 

4

 

Matching does not start in 
auto mode. (Does not 
operate.)

 

Configuration mistake

 

For local operation, set to AUTO.

 

For remote operation, open pins 
1-9.

 

Auto matching controller problems

 

Contact ULVAC.
