GE Information
Controls Switch
Table: Controls
Switch and
States
The operation of the Controls switch
only
affects the circuitry that controls
the digital output relays of the D25 control modules.
Refer to the 994-0046 D25 KI Interposer Relay Panel Quick Start Guide for
information on the use of 517-0462 and 517-0463 KI relay interposer panels.
When operated, the switch has these functions:
Control State as
indicated by LEDs
Function
LOCAL
•
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 open
condition as soon as possible and pending requests are
eliminated.
The D25 cannot operate any digital output points, and
therefore permits the safe servicing of connected
equipment and wiring.
REMOTE
Physical digital outputs are enabled, and can be
operated at any time from:
•
a host (remotely), or
•
the WESMAINT II+ interface.
Digital output requests are accepted and processed.
LOCAL / REMOTE
FLASHING
Local/Remote LEDs flashing indicate one or more
active sealed-in outputs (only if a D25 High Current
KE Control Output Module is present in the D25)
The
CONTROLS
switch
does not
affect auxiliary digital outputs
(D25 HCKE
Only)
When moving L/R switch in Local position, all control outputs will be
disabled
except outputs with active seal-in current level
.
When the front panel Local and Remote LEDs are flashing do not turn off the
D25 IED power supply. Seal-in is in effect and breaking the current can
damage 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 as
an auxiliary breaker contacts)
