When the instrument is turned on, the drain valve opens to vent the vessel. If the drain open/close switch is not sensed by the computer, this fault occurs. Possible Causes: (1) Wires on the drain valve have become dislodged. Connections may have...

Rinse water can come directly from the tap. It does not have to be distilled.

Possible Causes: The solution temperature has exceeded the maximum limit. Perform the boil test detailed in Service Procedure Boil Test (AS013).

The enzyme tubing should be changed annually under normal use. Heavy use may necessitate a shorter timeframe between tubing changes. The Enzyme Tubing Replacement Kit ( Part #: TDF67 ) is available for purchase by contacting ANKOM Technology at (315)...

This issue may occur if the instrument is not fully purged of the residual enzyme left in the supply lines, especially Trizma. ANKOM recommends flushing the enzyme supply lines with alcohol weekly when enzymes are being used. Further, we recommend...

The enzyme tubing may be clogged. Look at the enzyme tubing from the reservoirs to the Enzyme Pinch Valve and beyond to the manifold. If there is any discoloration or gelled material in the tubing, replace the tubing. Contact ANKOM Technology at...

Do NOT run this instrument without an adequate DRY Nitrogen Supply. The instrument is powered by pneumatics that are not compatible with moisture, commonly found in compressed air. Nitrogen is also recommended as an extra precaution when handling...

Refer to Service Procedure High Blank Bag Values (DES035).

The Blank Bag Correction allows for a weight adjustment based on actions that take place during solubilization. The resulting factor increases or decreases your sample bag weight. To determine the blank bag correction, include at least one empty...

When the neutral detergent solution gets cold, some of the components will begin to precipitate out of solution. As a result, the solution will turn milky white, and particles will be floating in it. These particles can be brought back into solution...

Depending on what you are testing, refer to section ADF Analysis, NDF Analysis, or Crude Fiber Analysis in the DELTA, A200, or A2000 Fiber Analyzer Operator's Manual.

A "Low Pressure" error occurs when the vessel does not have at least 3 psi after 13 minutes. Possible Causes: (1) The lid was not tight. You do not have to over tighten the lid, but it needs to be snug. Usually, a finger tight + 1/4 turn is adequate...

This problem could point to one of four possible issues with the instrument. Investigate in the order below. (1) There could be a hole in the suspect bag position’s fluid line after or within the Pump causing a leak in the back of the instrument. To...

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...

During a crude fiber or acid detergent procedure, the time frame during which samples are exposed to 100°C solution(s) is extremely important. If the Fiber Analyzer begins a procedure at a temperature higher than 20°C, the instrument will heat the...

We have found that it is best to slowly ramp up the digestion temperatures so that foaming in the digestion tubes is minimized. As a result, we would suggest the following times and temperatures: 15 minutes at 150°C, followed by 15 minutes at 250°C...

To properly set up your instrument for the various fiber analyses, refer to the A2000 Operator's Manual.

A "drain error" usually occurs if the level sensor senses the solution in the vessel after the drain has opened. If the vessel is empty, and the level sensor indicates "Full," the level sensor must be fixed. If the vessel is full of solution after...

"----" indicates there has been an electrical malfunction. Reset the Controller. Refer to A2000 Service Procedure Controller (Temp) Menu Setup (AS015). If the "----" still shows, you will need to replace the Ascon Controller ( Part #: A09 ). Possible...

Possible Causes: Faulty A2000 Temp Controller ( Part #: A11 ). Refer to Service Procedure Controller Temp Test (AS014). Faulty Splat Controller ( Part #: A09 ) Poor Connection between the Temp Controller and the Splat Controller (AS020).

Refer to Service Procedure Agitation and System Check (DES031).

It is possible to follow an NDF run with an ADF run using the same sample and Filter Bag. However, samples that are high in pectin, tannins, glucans, and fructans can produce lower-than-expected ADF values when NDF was run first. This is because...

F57 The porosity of the ANKOM F57 Filter Bag is 25 microns. The design of the filter bag provides a three-dimensional filter matrix similar to the filtering effect of a glass crucible. The F57 Filter Bag provides equal filtration without the manual...

Our grinding recommendation for samples to be extracted in our Fiber Analyzer is: 1 mm with a Wiley Mill 2 mm with a Cyclone Mill (such as UDY or Retsch)

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...

Possible Causes: (1) The packing nut may be too tight. For proper tightening instructions, refer to Service Procedure Agitator Packing Maintenance and Nut Adjustment (AS001). (2) The packing assembly may have corrosive buildup. If periodic...

The F57 and F58 Filter Bags are ash-free and therefore can be used for ash determination. Refer to the Ashing Procedure Service Procedure (AS034) linked below.

Refer to Service Procedure Insert Samples Into F58 Bags (AS032).

To minimize bag material abrasion, use the new bag suspender (as of March 2015 - Part #: F11 ). It has been redesigned to include rounded bottom points on each tray.

Bag breakage can occur when the heat sealer setting is not hot enough to ensure a good seal. Make sure each bag is sealed within 4mm of its open end. This section includes a narrow polypropylene strip that provides elasticity to the heat-sealed area...

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...

Possible Causes: A leak has occurred at the agitator shaft. The packing nut requires attention. Refer to Service Procedure Agitator Packing Maintenance and Nut Adjustment (AS001). If tightening the packing nut does not stop the leak, you will need to...

Test the rinse water with litmus paper during the last minute of the fourth hot water rinse. If the test indicates the presence of acid, repeat with fresh, hot water until a neutral pH is achieved.

Neutral detergent consists of varying amounts of 4 dry chemicals and triethylene glycol. If you remove only a portion of the dry chemicals to make less than 20L of solution, it is impossible to know if the solution has the correct ratio of chemicals...

Amylase is utilized to help digest the starch in the sample. Even using expired Alpha Amylase, it is highly likely the non-starch components, as well as most of the starch, are gone. Put the Filter Bags in a 1 L beaker with 80 °C water and 8 ml of...
