Operating AssistanceQuick View MenuPresentationThe Quick View menu presents the information essential for operating the device connected to the frontdisplay module FDM121, divided into a number of screens.The number of available screens and their content depend on the device connected to the front displaymodule FDM121. For example, with Compact NSX circuit breakers, they depend on:• The type of Micrologic trip unit (A or E)• The number of circuit breaker poles (3-pole or 4-pole)• The presence of options (ENVT or ENCT)The screen number and number of available screens are indicated in the top right-hand corner of thedisplay.NavigationNavigation within the Quick View menu is as follows:• The and keys are used to go from one screen to another.• The ESC key is used to return to the main menu.• The key is used to modify the display mode.Example of Screens in the Quick View MenuThe table below shows screens 1 to 7 of the Quick View menu for a Compact NSX 4-pole circuit breakerequipped with a Micrologic E trip unit:ScreenDescriptionScreen 1 in the Quick View menu displays:• The name of the IMU (Aircon FDR on the screen example opposite).The name of the IMU defined with RSU can be up to 45 characters long, but only thefirst 14 characters are visible on the front display module FDM121.• The Open/Closed/Trip status of the Compact NSX circuit breaker (if the BSCM moduleis present (Open on the screen example opposite)• The status of the LED indicators on the front of the trip unit• The long time protection Ir pick-up setting• The current intensity of the most heavily loaded phase (I2 = 217 A in the screenexample opposite)Screen 2 in the Quick View menu displays the currents:• Phase 1 current I1• Phase 2 current I2• Phase 3 current I3• Neutral current INScreen 3 in the Quick View menu displays the phase to phase voltages:• Phase 1 to phase 2 voltage V12• Phase 2 to phase 3 voltage V23• Phase 3 to phase 1 voltage V31Screen 4 in the Quick View menu displays the phase to neutral voltages:• Phase 1 to neutral voltage V1N• Phase 2 to neutral voltage V2N• Phase 3 to neutral voltage V3N146 LV434104 09/2009
