D25User's Manual GE Grid Solutions106 994-0081-3.00-21 GE InformationControls SwitchTable: ControlsSwitch andStatesThe operation of the Controls switch only affects the circuitry that controlsthe digital output relays of the D25 control modules.Refer to the 994-0046 D25 KI Interposer Relay Panel Quick Start Guide forinformation on the use of 517-0462 and 517-0463 KI relay interposer panels.When operated, the switch has these functions:Control State asindicated by LEDsFunctionLOCAL • All physical digital outputs are disabled.• All active operations are aborted.• All digital output requests are rejected.• All queued requests are cleared.• All digital outputs return to the normally opencondition as soon as possible and pending requests areeliminated.The D25 cannot operate any digital output points, andtherefore permits the safe servicing of connectedequipment and wiring.REMOTE Physical digital outputs are enabled, and can beoperated at any time from:• a host (remotely), or• the WESMAINT II+ interface.Digital output requests are accepted and processed.LOCAL / REMOTEFLASHINGLocal/Remote LEDs flashing indicate one or moreactive sealed-in outputs (only if a D25 High CurrentKE Control Output Module is present in the D25)The CONTROLS switch does not affect auxiliary digital outputs(D25 HCKEOnly)When moving L/R switch in Local position, all control outputs will bedisabled except outputs with active seal-in current level.When the front panel Local and Remote LEDs are flashing do not turn off theD25 IED power supply. Seal-in is in effect and breaking the current candamage the control card. Ensure there is no current present on the D25 HCKE(e.g. through an external current interruption in the respective circuit such asan auxiliary breaker contacts)
