19. Front panel userinterfaceThe 630 series IEDs can be ordered with andetached front-panel user interface (HMI). Anintegrated HMI is available for 4U highhousing. The local HMI includes a largegraphical monochrome LCD with a resolutionof 320 x 240 pixels (width x height). Theamount of characters and rows fitting theview depends on the character size as thecharacters' width and height may vary.In addition, the local HMI includes dedicatedopen/close operating buttons and fiveprogrammable function buttons with LEDindicators. The 15 programmable alarm LEDscan indicate a total of 45 alarms. The localHMI offers full front-panel user-interfacefunctionality with menu navigation, menuviews and operational data. In addition, thelocal HMI can, using PCM600, be configuredto show a single-line diagram (SLD). The SLDview displays the status of the primaryapparatus such as circuit breakers anddisconnectors, selected measurement valuesand busbar arrangements.GUID-5CFD3446-A92F-4A5F-B60D-90025DCFDC61 V2 ENFigure 4. Local user interface20. Mounting methodsBy means of appropriate mountingaccessories the standard IED case for the 630series IEDs can be flush mounted, semi-flushmounted or wall mounted. Detachable HMI isintended for optimized mounting in mediumvoltage metal-clad switchgear, thus reducingwiring between the low-voltage compartmentand the panel door. Further, the IEDs can bemounted in any standard 19” instrumentcabinet by means of 19” rack mountingaccessories.For the routine testing purposes, the IEDcases can be installed with RTXP testswitches (RTXP8, RTXP18 or RTXP24) whichcan be mounted side by side with the IEDcase in a 19” rack.Mounting methods:• Flush mounting• Semi-flush mounting• Overhead/ceiling mounting• 19” rack mounting• Wall mounting• Mounting with a RTXP8, RTXP18 orRTXP24 test switch to a 19”rack• Door mounting of the local HMI, IED casemounted in the low-voltage compartment ofthe switchgearMotor Protection and Control 1MRS756977 DREM630Product version: 1.1 Issued: 2011-05-18ABB 55
