TROUBLESHOOTING
E4 Series II system Error Log
The system Error Log is displayed when the
E4 Series II Installer™ software is in the
Service Hardware mode.
Contents of the Error Log
The Error Log displays system hardware
version numbers and records all alarms and
their causes as shown in the following
example.
Hardware configuration
The system hardware version numbers
appear at the top of the Error Log listing.
These are the version numbers of the
software installed in the hardware at the time
of manufacture. These version numbers do
not pertain to the Installer™ software in-
stalled on your PC.
Power-on self-test results
The power-on-self test (POST) results are
only displayed when an error has occurred.
The POST test checks the basic operation of
the E4 Series II hardware to determine if it is
capable of properly performing audio pro-
cessing and amplification. During the POST
test, six major components of the hardware
are tested.
• Host controller – The host controller moni-
tors and controls the operation of the system
hardware. A host controller failure will cause
the message, “Power-on self-test incom-
plete” to appear in the host controller test
section. The failure type for a host controller
is an SRAM address failure.
• Flash memory test – The flash memory
contains the configuration, design file, and
system event schedule. A flash failure will
cause the message, “Power-on self test
incomplete” to appear in the host controller
flash test section.
• Peripheral controller – The peripheral
controller monitors contact closures, front
panel connections and user interface con-
nections for incoming event messages. Any
failures in these areas will cause the mes-
sage, “Power-on self-test incomplete” to
appear in the peripheral controller flash test
section. If a user interface failure occurs,
check the user interface wiring for shorts.
• DSP test – The DSP performs all signal
processing and routing functions.
• Upper and lower amplifier test – The upper
and lower amplifier test determines if the
amplifiers are operating properly. An ampli-
fier failure will cause the message, “Power-
on self-test incomplete” to appear in the
upper or lower amplifier section of the POST
test results. Additional details on the exact
cause of an amplifier failure can be found in
the amplifier section of the Error Log.
• Front panel board test – The front panel
board test deter-mines if the USB port is
working properly. A USB failure will cause
the message, “Power-on self-test incom-
plete” to appear in this section of the POST
results.
Note: The USB port is not currently used for
communication with the E4. If a USB failure
occurs, the E4 will still function normally for
audio processing and amplification.
