Section 3 1MRS757256 F Basic functions Each indication LED on LHMI can be set individually to operate in six different sequences; two as follow type and four as latch type. Two of the latching sequence types are intended to be used as a protection indication system, either in collecting or restarting mode, with reset functionality.
Page 45 Section 3 1MRS757256 F Basic functions positive-edge triggered, not level triggered. This means that even if the button is continuously pressed, the acknowledgment/reset only affects indications active at the moment when the button is first pressed. • Automatic reset • Only indications defined for re-starting mode with the latched sequence type 6 (LatchedReset-S)The can be automatically reset.

Page 47 Section 3 1MRS757256 F Basic functions When a LED is acknowledged, all indications that appear before the indication with higher priority has been reset, are acknowledged, independent of if the low priority indication appeared before or after acknowledgment.

Section 3 1MRS757256 F Basic functions 3.2.4.3 Operation principle Each output on the FNKEYMD1 - FNKEYMD5 function blocks can be controlled from the LHMI function keys. By pressing a function button on the LHMI, the output status of the actual function block changes. These binary outputs can in turn be used to control other function blocks, for example, switch control blocks, binary I/O outputs etc.

Section 7 1MRS757256 F Power management functions If there are no external connections to adjacent electrical network areas, the external connections can be configured as grid transformers.

Section 7 1MRS757256 F Power management functions • Phase overcurrent detection module has operated. • Calculated average demand is violated. • External input is configured and the input gets activated, for example transformer or feeder overcurrent IED (RET/REF630) start signals. If the power flow of the power source is away (that is, power flow direction is negative) from the busbar, slow load-shedding trigger from the respective power source is not initiated.

Section 7 1MRS757256 F Power management functions PML630 performs load-shedding action in its own area, provided that an adjacent PML630 has executed the load-shedding action and the actual shed load is less than required. PML630 receives the load-shedding information from an adjacent PML630 to shed identified loads in its own area.
