Over a period of years, the buffer valve, and possibly others, may begin to corrode the brass valve body. As of November 2022, the buffer valve in new instruments comes with a PEEK chemical-resistant valve body. However, older instruments may show...

The XT instrument’s flowmeter should have a flow rate between 4-6 gallons per hour (If chilled coolant is used then the flow rate should be 2-3 gallons per hour). Note that this flow is intermittent and only turns on when cooling is required. When...

The vessel temperature has exceeded the maximum limit. Possible Causes: The solution level is low in the vessel, but the level sensor is indicating full. The level sensor has two main components that work together. These components are a Level Sensor...

Maintenance is low. At the end of the day, the digestion vessel spray nozzles, digestion vessel bases, and SPE column top rings must be wiped clean with a dampened towel. Some O-rings require replacement generally after about two hundred runs. Refer...

Possible Causes: The power cord is not plugged into the unit or power source. The main power switch is not turned on. One of the system circuit breakers (fuses) needs to be replaced. Refer to DELTA Service Procedure Fuse Replacement (DES025).

When using the Mojonnier mixture of solvents, a black residue may build up on the bottom of the vessel. If this coating becomes too thick, an "Overtemp Fault" "<Enter>" may occur. The black residue can be cleaned using a drill with a long-shafted...

The solenoid will become hot if the valve open check box is left checked. Normal valve openings are very brief and within a range of 10-1000 milliseconds, which does not cause the solenoid cylinder to get hot. If the Open Valves button is clicked or...

For illustrations of melted trays, see A200 Service Procedure Temp Probe Replacement (FS016). Bag suspender trays can melt when there is not enough solution in the vessel to cover all of the trays while the instrument's heat is activated. Possible...

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...

The following are two possible reasons why enzymes may not be drawn from the reservoir. (1) The silicone tubes may be worn or flattened from use. To inspect the tubing, refer to TDF Service Procedure Tube Replacement (Pinch Valves) (TS005) and...

Replacement of the dryer completely depends upon how often it is used to dry hydrolysis samples. The filter should be changed when the filter bags do not dry sufficiently after hydrolysis at 110°C for three hours (adding pH paper in the desiccant...

When using the ANKOM Rapid Dryer to dry acid hydrolysis samples, the airflow through the special hydrolysis filter ( Part #: RD2 ) will eventually become too limited and the filter will need to be changed. To check the air filter for proper airflow...

Yes, Electrostatic Discharge (ESD) can cause the flash programming of the XBee chips in your #RF1, RF1X , # RF5 , and RF5X modules to become corrupted and stop communicating with the RF GPM software. Therefore, we highly recommend using an ANKOM Anti...
