Firmware revision (Fr)
You can use the firmware revision (Fr) display group to determine the version of EMU firmware.
To view the EMU firmware revision:
1. Tap the bottom push button until the alphanumeric display shows Fr.
2. Tap the top push button to cycle through four pairs of digits that indicate the firmware revision.
• The first pair of digits is the major version number, displayed with both decimal points off
(for example 01).
• The second pair of digits is the minor version number, displayed with the left decimal point off
and the right decimal point on (for example 01.).
• The third pair of digits is the first half of the build number, displayed with the left decimal point
on and the right decimal point off (for example 0.1).
• The fourth pair of digits is the second half of the build number, displayed with both decimal
points on (for example 0.1.).
For example, EMU firmware revision 2.2.68 is displayed as:
02 02. 0.0 6.8.
The display cycle is repeated if the top push button is tapped again.
3. To exit the firmware revision display, press and release the bottom push button.
The display returns to Fr.
Error condition report (Er)
You can use the error condition report (Er) display group to determine the source of an error. When
an error occurs, the EMU generates an error condition report. You can use the push buttons view the
six-digit error condition report:
• The first two digits identify the component or element type (et) that is the source of the error,
displayed with both decimal points on (for example, 0.1.).
Table 6 lists the et codes.
• The next two digits identify the specific component or element number (en) that produced the
condition, displayed with the left decimal point off and the right decimal point on (for example,
01.).
• The last two digits is an error code (ec), displayed with both decimal points off (for example, 01).
For example, a left blower failure appears as:
0.3. 01. 03
The display cycle is repeated if the top push button is pressed. You can tell which pair of digits are
displayed by the decimal points.
