I usually work on a lot of Voyager units, and this Intellipak is my first of that series.
Called to the site for no AC.
Human Interface shows "emergency stop."
Diag list shows Emergency Stop as an active code.
Enter the proper procedure for clearing the active code, including the password.
HI accepts the password, says it is resetting the data.
Emergency Stop remains as an active code.
Tried to clear code again. Same result.
Cut power to machine via disconnect. Restored power.
Machine reboots, data resets.
Machine has cleared the code, and resumes normal operation.
Fast forward a week.
See above, same scenario.
Now, my task is to determine why "emergency stop" is appearing on the HI.
My suspects are:
1) Someone who uses the roof for a smoke break (there is a stairway used by some employees of the building, although none work for the store whose space is affected by this machine) is pressing emergency stop, and the machine is responding as intended.
2) There is some sort of issue with the U48 board. (Because of the problem with clearing the code, I'm leaning toward the board.)
