GE Multilin F650 - Negative Sequence Current; Thermal Model

6-6 F650 DIGITAL BAY CONTROLLER GEK-106310-AF
6.2 STATUS CHAPTER 6: ACTUAL VALUES
6.2.3.6 Negative sequence current
This screen shows the pickup and trip for negative sequence elements in the F650. Any of these two events of any ground
element lights up the corresponding LED in this screen, and it remains lit while the associated function remains in pickup or
operation.
This screen is accessed in menu: Actual> Status > Protection >Negative Sequence Current, and includes the following
signaling LEDs:

6.2.3.7 Thermal model
F650 units incorporate up to 3 thermal image elements. For each of them, this screen shows by means of green LEDs, the
activation of the reset, alarm, operation and thermal image signals for each phase (A, B, C) and each unit (1, 2, 3). Any of the
reset, alarm and operation signals light up the corresponding LED in this screen, and it remains lit as the associated
function remains in reset, pickup or operation. This function also provides the thermal image value for all the phases and
functions in percentage. All the values are provided individually for phases and for the three thermal elements.
This screen is accessed in menu: Actual> Status > Protection >Thermal image, and includes the following signaling LEDs:
