PLM Series Operation Manual rev 1.1.39. Front Panel Interface499.12 Meter ModeIn METER mode, there are three possible screen displays, referred to as “Views”. Pressing the METERbutton scrolls through the three views in turn: Home, Module, Temperature and Input. Each of the fourviews provides different information about the PLM’s performance and settings.The four views are similar in layout. The display screen is divided into eight “blocks”, arranged in twocolumns of four, so that each block is associated with one soft button/tricolor LED. Each block has four rowsof alphanumeric characters, either showing textual information or acting as bargraph meters.In addition, four sets of alphanumeric characters are displayed in inverse video in the screen center betweenthe left and right columns. These provide confirmation of the PLM’s Module/output configuration. Theletters A or B refer to the two Lake Processing modules, and the numbers 1-4 to the up to four of PLM’spower output channels. The two examples below are given as illustration of two different module configura-tions on a four-channel PLM.If the processor is configured as two independent 2-way crossovers, the relationship between inputs andoutputs will be indicated as shown:CL2W-50CL2W-24HOME10000Q- - - -LOW-45HI-11LOW-13-∞-∞-∞HI-09-02A1A2B3B4Figure 9.12a: Dual 2-waycrossover configurationThis indicates that output channels 1 and 2 are driven from Module A and output channels 3 and 4 fromModule B.If the processor is configured as a single 4-way crossover, the relationship between inputs and outputs willbe indicated as shown:
