Troubleshooting and Diagnostics
12.1.4 INJ ERTH FAULT error is displayed.
If the error is displayed at the moment when the inlet temperature is ramped with the high
ramp rate, check the following:
Inlet power connection polarity is not correct.
Ensure that power to the instrument is switched
OFF. Disconnect the power leads from inlet and
reconnect them properly. Clean terminals and
reconnect them securely to inlet. Ensure that the
terminal 2 (right) of the inlet power connector is
connected to the upper inlet electrode.
12.1.5 Inlet Cools Down Slowly
If for inlet it takes an excessive time to cool down to the initial temperature set in the method, check
the following:
Compressed air supply pressure is too low
Ensure that air pressure supply is at least 500 kPa
LN
2
vessel pressure is too low (for LN
2
cooling)
Ensure is that LN2 vessel pressure is at least 150
kPa
12.1.6 Flow/Pressure Set Point Can Not be Reached
If the column flow set point cannot be reached and INJ PRESSURE WARNING is displayed, check the
following:
No carrier gas is supplied
Ensure that gas supply valve is opened
Supply pressure is too low
Set gas supply pressure to at least 500 - 600 kPa
Internal column diameter, column length and
carrier gas type and column outlet pressure are
set incorrectly
Set correct column parameters, carrier gas type
and column outlet pressure
12.2 Errors and Warnings
All OPTIC-4 error and warning messages are displayed in the status pane of the Evolution
Workstation. An intermittent beep will sound when an error or warning message is displayed.
12.2.1 Inlet Thermocouple Fault
The error message INJ TC FAULT is generated when the inlet thermocouple fails, or if the TC
connection to the OPTIC-4 control unit is lost. This error is displayed in the status pane if the
