2.2SPECIFICATIONSSPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE
The operating times below include the activation time of a trip rated form-A output contact unless otherwise indi-
cated. FlexLogic™ operands of a given element are 4 ms faster. This should be taken into account when using
NOTE
FlexLogic™ to interconnect with other protection or control elements of the relay, building FlexLogic™ equations, or
interfacing with other IEDs or power system devices via communications or different output contacts.

PHASE DISTANCE OPERATING TIME CURVES
The operating times are response times of a microprocessor part
of the relay. See output contacts specifications for estimation of
the total response time for a particular application. The operating
times are average times including variables such as fault inception
angle or type of a voltage source (magnetic VTs and CVTs).
