Error detected by TCC-LINK central control device
Error detected by AI-NET central control device
∗
These errors are concerned to communication of remote controllers (A, B) and central system [AI-NET X, Y], and the main remote controller displays [E01], [E02], [E03], [E09], or
[E18] in some cases and displays none in other cases according to the contents.
