Chapter Eight: Troubleshooting

Troubleshooting Chart

MFC output shows large
overshoot

Inlet pressure too high

Decrease inlet pressure

MFC not programmed for
correct gas - actual gas used
different

Check MFC active gas using digital
interface or Ethernet GUI

MFC control parameters set
incorrectly

Contact MKS service center

MFC output slow to
respond to setpoint

Inlet pressure too low

Increase inlet pressure

MFC not programmed for
correct gas - actual gas used
different

Check MFC active gas using digital
interface or Ethernet GUI

MFC control parameters set
incorrectly

Contact MKS service center

Output signal > zero with
confirmed zero flow
condition

MFC device zero offset

Re-zero device per instruction
manual

Fault in valve adjustment, gap
between plug & orifice

Contact MKS service center

Pressure output signal
different than confirmed
line pressure

Zero offset in pressure
transducer

Re-zero pressure transducer using
known pressure standard & Ethernet
GUI

Pressure output signal is
0

Closed upstream pneumatic
valve

Open valve

Closed or faulty regulator

Check regulator for proper
operations

Upstream clog filter

Measure pressure drop across filter
to spec, replace if necessary

No gas supply

Turn on gas source
