Errors and Warnings / OPTIC-4

Solution

All OPTIC-4 error and warning messages are displayed in the status pane of the Evolution Workstation.

 

>> 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 problem persists for two seconds or more. The inlet heater controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again. If the error remains most likely the inlet body needs to be replaced.

 

>> Inlet Earth Fault

The error message INJ EARTH FAULT is generated when the inlet thermocouple loses its connection to the body of the inlet, if the inlet TC connection to the OPTIC-4 control unit is lost or if the earth connection between the inlet base and GC chassis is broken. This error is displayed in the status pane if the problem persists for two seconds or more. The inlet heater controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

 

>> Inlet Overpower

The error message INJ OVERPOWER is generated when the application of full power for more than 25 sec does not bring the inlet temperature to the set point. This error is displayed in the status pane if the problem exists for two seconds or more. The inlet heater controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

This error could be there because of bad connected heater cable, leaking cooling valve, wrong installed inlet (the lower part of inlet body is in contact with the chassis of the GC)

 

>> Inlet Temperature above Maximum

The error INJ TEMP ABOVE MAX message is generated when the inlet temperature exceeds the maximum temperature of 650°C. This error is displayed in the status pane if the inlet temperature is above 650°C and is rising. The inlet heater controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

 

>> Cryotrap Thermocouple Fault

The error message CRYO TC FAULT is generated when the cryotrap thermocouple fails, or if the cryotrap TC connection to the OPTIC-4 control unit is lost. This error is displayed in the status pane if the problem persists for two seconds or more. The cryotrap and inlet heater controllers are shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

 

>> Cryotrap Earth Fault

The error message CRYO EARTH FAULT is generated when the cryotrap thermocouple loses its connection to the body of the trap, if the cryotrap TC connection to the OPTIC-4 control unit is lost or if the earth connection between the cryotrap base and OPTIC controller is broken. This error is displayed in the status pane if the problem persists for two seconds or more. The cryotrap heater controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

 

>> Cryotrap Overpower

The error message CRYO OVERPOWER is generated when the application of full power for more than 25 sec does not bring the trap temperature to the set point. This error is displayed in the status pane if the problem exists for two seconds or more. The cryotrap heater controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

 

>> Cryotrap Temperature above Maximum

The error CRYO TEMP ABOVE MAX message is generated when the cryotrap temperature exceeds the maximum of 400°C. This message is displayed on the local display (status line) if the cryotrap temperature is above 400°C and rising. The cryotrap heater controller is switched OFF. This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.

 

>> Inlet Temperature Warning

The INJ TEMP WARNING message is generated when inlet temperature set point cannot be reached during the method initialization, method run or standby. This message is displayed in the status line of the Evolution Workstation software. The software checks that the ramp is following its course and maintained correctly. If the actual temperature is ±50°C from the set point then INJ TEMP WARNING is displayed. This is a warning and is therefore recoverable.

 

>> Cryotrap Temperature Warning

The CRYO TEMP WARNING message is generated when cryotrap temperature set point cannot be reached during the method initialization, method run or standby. This message is displayed in the status line of the Evolution Workstation software. The software checks that the ramp is following its course and maintained correctly. If the actual temperature is ±50°C from the set point then CRYO TEMP WARNING is displayed. This is a warning and is therefore recoverable.

 

>> Inlet Pressure Warning

The INJ PRES WARNING message is generated when the inlet pressure (column flow) set point cannot be reached during the method initialization, method run or standby. This message is displayed on the local display and the PC. The software checks that the pressure (column flow) is maintained at the set point. This message is generated if the actual pressure differs by ±25 kPa from the calculated set point (which is required to set the column flow) for two minutes. This is a warning and is therefore recoverable. Please check article 7

 

>> Auxiliary Flow Warning

The AUX FLOW WARNING message is generated when the auxiliary flow set point cannot be reached during the method initialization, method run or standby. This message is displayed in the status pane of the EW on the PC. The software checks that the auxiliary flow is maintained at the set point. This warning message is generated if the actual flow differs by ±20% or ±2 mL/min (whichever is higher) from the set point for two minutes.This is a warning and is therefore recoverable.
