6. Quick Guide Overview
The brightness of the display and the adjoining network activity LED can be adjusted in the Frame page of
the Main menu.
Comprehensive details of the various display pages and the associated controls are given in section 9 –
Front Panel Interface.
Standby
The PLM is powered on and off by the top left-most button, STANDBY. See Lake Controller User Manual
PLM Addendum (sections 5.3.1 and 5.7) for further information regarding local and remote power control.
Mute Enable
Select MUTE ENABLE to allow muting via the soft function buttons of the inputs to the Lake system,
the power output channels, or both. The MUTE ENABLE legend in the button flashes when the mode is
selected. A second press will deselect the mode; however, if left active, MUTE ENABLE mode will auto-
matically cancel after two minutes if no further mute actions are taken.
Meter
The METER button scrolls through four alternative views: HOME, MODULE, TEMPERATURE and INPUT.
Pressing METER when in MENU mode returns the screen to METER mode, and the HOME view is
displayed.
The display has two basic operating modes: METER
(default) and MENU.
Menu
Pressing the MENU button puts the screen display into MENU mode, and the "top" page of the MENU
"tree" is displayed. Once in MENU mode, the function buttons enable the user to navigate the menu tree
and access most PLM Series operating functions. See sections 9.12.2 to 9.12.8 for more details.
Soft Function Buttons
Eight soft function buttons are set adjacent to the display in two groups of four. These buttons are unlabelled
because their functions change according to the current menu mode as displayed on the screen. In MENU
mode they are used to navigate the menu tree and for the selection of parameters to edit. In METER mode
they will act in conjunction with the MUTE ENABLE feature.
Status LEDs
Eight tricolor LEDs are integrated into the soft function buttons for convenience. These convey both fault
and warning indications, plus the currently selected mute status of the Lake Processing system inputs and
the output channels. Full details can be found in section 9.10.
High-intensity LED
A white, high-intensity LED is located to the right of the display. This LED illuminates when the PLM Series'
control system is being accessed remotely via the Lake Controller software. Steady illumination of the white
LED indicates that the unit is selected in the Lake Controller software; a flashing white LED indicates a change
in parameters or operating state.
