Troubleshooting - FAQ

  1. How do I wire the motor on my automatic sampler?

    You can find the motor wiring diagram for your automatic sampler in our resource library. Search for the motor part number using the search function. The part number for the motor can be found on the final assembly drawing of your sampler.

  2. My Temperature Control Unit (TCU) is not working properly, what do I do?

    We are sorry to hear your equipment is not functioning as expected. Please contact us at support@sentry-equip.com or at 262-567-7256 ext 8999 with the unit's Model Number and Serial Number so we can assist you with your needs. 

    For units older than 2012, model number and serial number information is available on the stainless steel nameplate. For units manufactured after 2012, the model number and serial number information is on a sticker on the inside, right hand side of the control box.

  3. What do I do if my air operated sampler will not move or is moving too slowly?

    First, check your operating air pressure to ensure it is set to the correct parameters per the sampler's operation manual. Second, make sure the correct voltage is present at the airset. Lastly, follow the instructions on Adjusting the Sample Probe Travel Speed. 

  4. Where can I find my product's serial number?
    Serial numbers can be found stamped on the product itself, on an adhesive nameplate or on a stainless steel tag.
  5. How do I troubleshoot my TCU PLC?

    TCU PLCs have great troubleshooting guides right in the programming. To access the troubleshooting guide, go to the alarm screen and select the troubleshooting button. The screen shots will show the various components with red arrows to indicate areas that may be causing the PLC issue. Touch the desired arrow and the program will take you to another screen instructing you on how to troubleshoot the problem.
