FLEXELEMENT 1 HYSTERESIS
— This setting defines the pickup–dropout relation of the element by specifying the width of the
hysteresis loop as a percentage of the pickup value as shown in the FlexElement Direction, Pickup, and Hysteresis diagram.
FLEXELEMENT 1 dt UNIT
— Specifies the time unit for the setting
FLEXELEMENT 1 dt
. This setting is applicable only if
FLEXELEMENT 1 COMP MODE
is set to “Delta.”
FLEXELEMENT 1 dt
— Specifies duration of the time interval for the rate of change mode of operation. This setting is
applicable only if
FLEXELEMENT 1 COMP MODE
is set to “Delta.”
FLEXELEMENT 1 PKP DELAY
— Specifies the pickup delay of the element.
FLEXELEMENT 1 RST DELAY
— Specifies the reset delay of the element.
5.6.7 Non-volatile latches

FLEXLOGIC
NON-VOLATILE LATCHES
LATCH 1(16)
The non-volatile latches provide a permanent logical flag that is stored safely and do not reset upon restart after the relay
is powered down. Typical applications include sustaining operator commands or permanently blocking relay functions,
such as Autorecloser, until a deliberate interface action resets the latch.

distance source, use the PhaseCTSecondary value from the CT with the highest primary nominal
current.
