Faults and Warnings Overview

Fault or warning conditions are indicated by the LED shown in Figure 6-3 on page 16. As the LED indicates
several types of faults or warnings, a brief textual description of the fault or warning is provided on the LCD
display. Section on page 19 details the fault and warning indications that appear on the front panel. Table 8-1
lists the events that may have triggered each fault or warning condition.

Type Description / Troubleshooting
There is a problem with the analog input. Verify signal and connec-
Fault
tions.
The selected digital clock and digital input combination is not
Warning aligned. Verify digital input configuration to ensure all clock settings
match.
The LM 26 is no longer able to communicate with the Lake Control-
Warning
ler. Check network connectivity.
There is a problem with the fan on the LM 26. To avoid overheat-
Fault
ing, identify and fix the problem immediately.
An input is muted; all Modules and outputs sourced from this input
Mute
will be affected.
No input signal of any type can be identified. Connect an input
Fault
source, or verify input signals and connections.
The temperature has reached a critical 70
Fault off or take steps to cool the unit immediately; continued operation
cannot be guaranteed.
A processor mute state has been triggered via GPIO. Change this
Event
setting using the external control device.
The temperature has reached 55
Warning ture and take additional steps to reduce temperature if it continues
to increase.
The Lake Controller is no longer able to communicate with the LM

26. Check network connectivity.
A Module Input has been muted. The mute is identified via the
Mute
associated Module Input mute button on the front panel.
A Module Output has been muted. The mute is identified via the
Mute
associated Module Output mute button on the front panel.
The input source has been changed either manually or by automatic
