In general, LEDs to the left of the display will indicate problems with the PLM or its inputs, while those
to the right indicate problems with the power output channels. Note that the same LEDs also indicate the
mute status of inputs and outputs.

9.1.2 Pinging modules in the Lake Controller software from the PLM
When a large system comprising multiple PLMs is in use, it may be desirable to positively identify a particu-
lar Module in the Lake Controller software. To achieve this, it is possible to Ping (or ‘highlight’) a Module on
the PC directly from the PLM.
The PLM should be in METER mode for this function to operate.
Press the soft button adjacent to the chosen Module’s input display, and the corresponding Module label
on the Lake Controller software will highlight in yellow text. If the Module is not yet placed within the work
area, then the Module scroll bar will place the highlighted Module mid-screen.
9.2 Key Lock Front Panel
It is possible to “lock out” the PLM’s front panel buttons for security purposes. When
this function is active, all control must be made via the control network. The lock is set
by pressing and holding the top left-hand soft button and then simultaneously pressing
the bottom left-hand button while holding the top button.Unlocking can be achieved by
repeating this process.
