This is likely due to a valve that may be "stuck" closed. If the instrument has not been used in a while, it is possible that the solution is simply to clean the valves and clean any debris or buildup that may have settled on the valve piston. To...
In the event of a Drain Time-Out Fault (MF7) or an Abort during a Drain Module, users must flush the lines beneath the vessels to clear the residue prior to starting a new run. For more information, refer to Section 17 of the FLEX Operator’s Manual...
Possible Causes: (1) The level sensor has failed to detect the liquid that is in the vessel. If the vessel is full and this fault screen appears, press <STOP> to drain the fluid. You may want to capture the solution and re-use it. Refer to DELTA...
An E11 fault is the result of the high-pressure sensor reading input pressure below 35 psi. N2 input pressure is always monitored and the fault could occur at any point during a run. The fault will interrupt the run and wait for the operator to...
Refer to XT15 Service Procedure Fault – ETS (X5S016). Note: Older XT15 software may present variations in fault wording. Should technical service be required, please photograph the fault screen so the technician can verify the software version.
This fault display means that at the end of the extraction, the level sensor detected solvent in the vessel (at the end of the run, the vessel should be empty and the sensor should not detect solvent). The instrument has either a Teflon Level Sensor...
This is likely due to a valve that may be "stuck" closed. If the instrument has not been used in a while, it is possible that the solution is simply to clean the valves and clean any debris or buildup that may have settled on the valve piston. To...
There is a leak. The most common cause is a leaky Q1 valve, which would cause cooling water to flow into the vessel during the heating stage. To test: Turn the instrument completely off but keep the water supply on. Check to see if water is running...
Refer to TDF Service Procedure E13 Diagnosis (TS001) to diagnose tubing pressure failure.
The touchscreen display will give you the option to Retry , Override , or Abort the run. Retry will simply try the delivery again. Override will ignore the fault for the remainder of the run. Abort will stop the run entirely. To analyze the problem...
This fault indicates that one or more of the Paddle Temperature Sensors is reporting erroneously low data of < 5°C. The fault message on the Touch Screen Display will indicate which station is having the problem and the heater to this station will be...
The Overtemp message happens when the ANKOM HCl Instrument is heating but there is no solution in the vessel. The quartz heaters will heat the vessel and the ETS (Emergency Temperature Switches) will trip. Possible Causes: The instrument was not...
The touchscreen display will give you the option to Retry , Override , or Abort the run. Retry will simply try the delivery again. Override will ignore the fault for the remainder of the run. Abor t will stop the run entirely. Possible causes include...
Cause: This fault occurs when the temperature sensor to the in-line heater reports that the in-line heater is not reaching the required 80˚C within the 90 seconds allotted during an EtOH95 delivery. The fault message on the touchscreen display will...
An E10 fault is the result of one or more of the six pressure sensors reading a pressure 20 psi above the baseline pressure during the buffer delivery to the IDF bags or during the EtOH 95 delivery to the SDF bags. This fault will abort the run. The...
A "Low Pressure" error occurs when the vessel does not have at least 3 psi. Possible Causes: The lid was not tight. You do not have to over-tighten the lid, but it needs to be snug. Usually finger tight plus 1/4 turn is adequate. Check the lid O-Ring...
Possible Causes: The solution temperature has exceeded the maximum limit. Perform the boil test detailed in the DELTA Service Procedure Boil Test (DES013).
Possible Causes: The rinse water supply temperature did not meet method standards. This may affect results with certain samples. Make sure the water supply has a temperature of no less than 50°C for Crude Fiber or no less than 70°C for ADF and NDF...
To get this fault, the temperature sensor in one or more of the paddle heaters is reporting high temperatures. This could occur at different times under specific conditions such as: During the Amylase phase or when the instrument is idle if a...
This fault occurs when the temperature sensor in the in-line heater reports a temperature exceeding 135˚C. The E4 error message on the touch screen display will indicate the temperature at the time of the fault. When this fault occurs the instrument...
This fault occurs when the temperature sensor reports a high temperature while the in-line heater is attempting to cool within the required timeframe. Cooling is facilitated by flushing water through the lines of the in-line heater. The first time...
An E12 fault is the result of the high-pressure sensors reading input pressure above 100 psi. N2 Input pressure is always monitored, and the fault could occur at any point during a run. The fault will interrupt the run and wait for the operator to...
Possible Causes: The Q6 Valve (drain valve) is not opening correctly or there is a line blockage between the Q6 valve and the vessel. To best assist you, run a ~10 minute test. Please contact ANKOM with your results. To test: Verify that the Q6...
This fault indicates a System Integrity Failure. One or more vessels did not reach or hold pressure properly. To resolve an MF1 fault: 1. Confirm the Low N2 setting is: 2.6 - 3.0 PSI. See Section 6.7.2 of the FLEX Operator’s Manual. 2. Tighten the...
Possible Causes: If liquid has been manually poured into the vessel before the computer communicates with the appropriate valve to fill the vessel, this fault screen will appear. Open the vessel, if the vessel is full press "Y<ENTER>" to continue the...
To get this fault, the temperature sensor in one or more paddle heaters is reporting low temperatures. This could occur at different times under specific conditions such as: During paddle pre-heat, if any one of the paddles does not reach 50°C in...
Cause: This fault occurs when the temperature sensor in the in-line heater reports that the in-line heater is not reaching the required 110˚C within the 90 seconds allotted during an IDF water rinse. The fault message on the touchscreen display will...
An E2 Fault is declared when the thermistor to the in-line heater is reporting an erroneously low reading of < 10˚C. IMPORTANT: An E2 fault can be caused by cold buffer running through the instrument. If you store your buffer solutions in the...
There is a leak. The most common cause is a leaky Q1 valve, which would cause cooling water to flow into the vessel during the heating stage. To test: Turn the instrument completely off but keep the water supply on. Check to see if water is running...
This fault display means the level sensor is indicating a full vessel when the vessel is actually empty. The level sensor has three parts: Glass Tip (visible inside the vessel) SICK Module (blue, found inside the electrical cabinet) Fiber Optic Cable...
There should not be any significant amount of solvent in the vent flask. If the solvent is dripping into the flask during the extraction, there may be a leak in valve Q7, and it may need to be cleaned or replaced. Refer to XT Service Procedure...
A drain error usually occurs if the level sensor is sensing solution in the vessel after the drain has opened. If the vessel is empty, and the level sensor indicates "Full," then the level sensor must be fixed. If the vessel is full of solution after...
For XT10, see Service Procedure Fault ETS (X0S002). For XT15, see Service Procedure Fault ETS (X5S016).
This fault indicates a System Integrity Failure. One or more columns or round bottom flasks did not reach or hold pressure properly. To resolve an MF24 fault: 1. Confirm the Low N2 setting is: 2.6 - 3.0 PSI. See Section 6.7.2 of the FLEX Operator's...
The drain valve has been told to open but after 30 seconds the drain-open switch has failed to open the drain. Possible Causes: (1) The wires on the drain valve have become disconnected. Unplug the instrument, check the drain valve and reattach any...
