The user interface (UI) board and the input/output (I/O) board must have same
software version for correct operation. If the UI board and the IO board do not
have the same software versions an error will be displayed on the UI. The error
displayed will depend upon which board has 2.x software and has 3.x.Either "X
BRL TEMP OUT" will be displayed or "H20 OUT" will be displayed followed 30
seconds later with "X BRL TEMP OUT". If either of these messages is displayed
after changing a control board check the software version. The current software
version for each board can be found through the menu screen. Select, MENU,
UNIT DATA, then press the "VER" key. The control boards will also have a label
marked with the part number. A -100 suffix has been added to the part numbers
for each of these boards to indicate version 3.0 software release.
The foreign language chips are software version dependent. Part numbers for
software version 3.0 chips have the base number of 629096931 followed by an
alpha suffix designating the language type.
The motor control boards and the main status board will still operate with either
version 2.x or 3.x software of UI and IO board.
When ordering replacement/service parts for any unit check the software ver-
sion of the UI and IO boards and be sure to order the correct board as listed in
Table 60..

off, shown in Figure 55.
