We are facing an issue with the DX200 Model when we run the liquid cycle temperature reaches the set point (121) but is not cut off after reaching and an error appears "High chamber temperature" on the display

The "High chamber temperature" error on the Systec DX200 Model during the liquid cycle at 121 °C could be caused by:
1. Faulty pressure controller 2. Faulty PT 100 temperature sensor 3. Safety temperature limiter being overstepped by more than 3.5 K during the sterilization phase
These issues can lead to chamber temperatures exceeding the set point, triggering the error and interrupting the cycle.

However, you MUST ensure that the reservoir container is filled with enough demineralised water BEFORE and DURING operation.
• Close the reservoir container with the cap. • Start the cycle again. DX Series only: The reservoir accommodates enough demineralised water for a standard sterilization process. For longer sterilization processes, the water level must be checked regularly and, if necessary, topped up.

4.5 Special features of pass-through autoclaves With the pass-through autoclaves of the Systec DX Series 2D, you can always only open one door. If you open the door on the clean room side, the door on the device side is automatically locked, and vice versa.
DX/DE S ERIES PERATION 4.6 Sterilization For sterilization, there are 11 different sterilization cycles at your disposal. The following gives you an overview of the operations you must carry out for the sterilization. 4.6.1 Overview Pay attention to the relevant safety instructions! This brief overview presupposes a knowledge of the relevant safety instructions for working with autoclaves and items sterilized in autoclaves.
The parameters can be adapted to the particular requirements of your laboratory! The Systec DX/DE Series is flexible in its design so as to be suitable for all the usual laboratory applications. For this reason, the cycle parameters are variable to a large degree.
DX/DE S ERIES PERATION 4.6.3 Loading the autoclave with solids (Cycle Nos. 1, 2 and 3) Do not autoclave any liquids with the solids cycle! The sterilization of liquids in solids cycles causes danger through boiling delays or exploding vessels and can result in serious injuries.
DX/DE S ERIES PERATION 4.6.4 Loading the autoclave with liquids (Cycle Nos. 6, 7, 8, 9, 10 and 11) Use the flexible temperature sensor! For the sterilization of liquids, an autoclave with a temperature- dependent door lock is required. The flexible temperature sensor must therefore be placed in the liquid or in a reference vessel.
Page 62
On opening the autoclave, tightly-closed vessels can still be at temperatures above the unloading temperature. Systec autoclaves offer an additional safety feature! The operator can set a cooling rate that fixes a minimum cooling time, depending on the cooling system and the loading.
DX/DE S ERIES PERATION 4.6.5 Loading the autoclave with waste in bags (Cycle Nos. 4 and 5) Do not autoclave any liquid waste! Only laboratory waste in solid form and with only a small proportion of liquid may be sterilized. Liquid waste must be sterilized in cycle nos.
When you have loaded the autoclave in accordance with the instructions, close the door. Automatic door locking! The Systec DX/DE Series is equipped with an automatic door lock. A lock ring grips the door and locks it securely. DX/DE -65 – 200: To facilitate the locking process for you, a vacuum is created when the door closes which holds the door closed until the safety ring has mechanically locked the door.

DX/DE S ERIES PERATION 4.6.7 Starting the cycle Make sure there is sufficient paper in the printer! If an optional printer is installed, it automatically logs the entire cycle procedure from the start of the cycle. The last metre of the paper roll is indicated by a red stripe. If necessary, read up on how to reload the printer paper in the chapter 06 “Options”.

DX/DE S ERIES PERATION Stopping the cycle manually does not speed up the process! By interrupting the process in the cooling-down phase, for example, you do not speed up the process. Please consider that the door can only be opened when the unloading temperature has been reached and atmospheric conditions prevail inside the chamber.
Page 69
DX/DE S ERIES PERATION Items possibly not completely sterilized! Depending on the point at which the sterilization process is interrupted, the sterilization may be incomplete. An interruption in the warm-up or sterilization phase causes the cycle to pass directly to the cool-down phase. In this case, to guarantee complete sterilization you must repeat the entire sterilization process! Meaning of the error messages!
DX/DE S ERIES PERATION 4.6.11 Opening the door When the sterilization process is completely finished and the specified unloading temperature and atmospheric conditions have been reached, the message Opening Door appears in the display. The door can now be opened. If the sterilization process is stopped prematurely, the error message Manual stop FAIL appears in the display.
DX/DE S ERIES PERATION − Appliances with exhaust filter: The procedure is the same as for appliances without an exhaust filter, however the start of the condensate draining must be confirmed with the Yes display key, as shown in the display after the message Drain condense ?.
DX/DE S ERIES PERATION 4.7 Parameters Description of the factory parameter setting! The parameters for the individual sterilization cycles can be adjusted to suit the individual circumstances in your laboratory. Changed settings must be documented in the appliance log book. If you are unsure about the parameter setting of the appliance in front of you, inform yourself about it before starting a cycle.

2 mmol/l. This corresponds to a total hardness of 11° German hardness. Water softening equipment may be required. In this case, please contact Systec GmbH. Suitable for the sterilization of tightly-shut vessels! Due to the support pressure supply, this type of rapid cooling is also suitable for the sterilization of liquids in shut vessels.
DX/DE S ERIES PTIONS 6.2 Accelerated cooling via ambient air ventilation, only for open vessels, without support pressure Not suitable for the sterilization of liquids in tightly-shut vessels! Liquids in closed vessels are only to be sterilized in cycles with rapid cooling and support pressure.

Do you have a question about the DX Series and is the answer not in the manual?
Questions and answers
We are facing an issue with the DX200 Model when we run the liquid cycle temperature reaches the set point (121) but is not cut off after reaching and an error appears "High chamber temperature" on the display
The "High chamber temperature" error on the Systec DX200 Model during the liquid cycle at 121 °C could be caused by:
1. Faulty pressure controller
2. Faulty PT 100 temperature sensor
3. Safety temperature limiter being overstepped by more than 3.5 K during the sterilization phase
These issues can lead to chamber temperatures exceeding the set point, triggering the error and interrupting the cycle.
