Problems in 375 applications
Thread Content
Our 375 unit, for some unknown reason, cannot enter HART mode; as soon as it tries to do so, a message appears stating that the shutdown button is not functional and that it is necessary to exit HART mode first. Experts, especially HART after-sales service technicians, provided explanations and outlined how to resolve this issue.
Was the Fn function key pressed by mistake? Is the yellow and green light on together now? Press Fn again to return to the green light and give it a try
It’s not as mentioned on the second floor. As a supplementary note: Among the five primary menus for HART applications, settings, etc., only the HART Applications option displays the message \"The shutdown button is disabled; exit HART Applications first\" as soon as it is accessed, while the other options can be used normally.
The following is the final reply. The reply from ROSEMOUNT AO can also be considered the answer from the person in the whole country who knows the most about 375. If trying the operation again doesn’t work, it can only be sent for repair. Solutions for frequent crashes and errors when accessing the Hart or FF functions – Perform RE-FLASH or RE-IMAGE operations (try RE-FLASH first; if the problem persists, then try RE-IMAGE. Additionally, only controllers version 2.0 and above support RE-IMAGE operations). If the 375 device experiences frequent crashes or errors when using the Hart Application, RE-FLASH or RE-IMAGE operations can resolve most of such issues. The specific steps are as follows: a. Enter the 375 Main Menu ； b. Select to go to Settings ； c. Select to go to About 375; d. Select Re-Flash (or Re-Image). e. Select Yes to confirm this operation, and make sure the charger is plugged in at this time; since the Re-Flash (or Re-Image) process is very power-intensive, it is essential to carry out this operation while the device is charged, otherwise it may lead to serious consequences that cannot be reversed. f. If the handheld device is already confirmed to be charged, press OK to start Re-Flash (or Re-Image). Please be patient; the Re-Flash process takes about 20 minutes, while the Re-Image process takes around 50 minutes. A prompt will appear on the screen after the operation is completed. Please follow the instructions.
