ECM Overview and Setup
58 UNT-SVX07D-EN
The ECM engine board features a nested menu integrated
user interface (UI) that supports:
1. Status display for instant touch-free confirmation of
unit operation.
2. Configuration parameter and value display and
modification changes (using integrated menu/set
buttons).
3. Error code prioritized reporting.
Status Display
The ECM engine board contains a four-digit, seven-
segment display that is used to present information in a
format close to real-world language, while having a small-
form factor. Most characters are immediately
recognizable; however, please consult Ta b le 14 and
Tabl e 15 for the graphical representation of each
alphanumeric character.
Note: Characters on the ECM engine board display
appear in red, on a black background.
The display contains decimal positions as well that change
position with each parameter, as appropriate. Under
normal conditions (i.e., with no error code displayed), the
status will loop the following message:

the engine board with the power on the unit, detach the
low voltage access lid and look or reach through the
low voltage access panel.
2. The ECM engine label is affixed to the back or front of
the low voltage access lid.
