I3>MaxEd2Set: Maximum settable operating phase current level for step 3 in % of IBase,
for 61850 Ed.2 settings
I4>MinEd2Set: Minimum settable operating phase current level for step 4 in % of IBase,
for 61850 Ed.2 settings
I4>MaxEd2Set: Maximum settable operating phase current level for step 4 in % of IBase,
for 61850 Ed.2 settings
Pickupx: Operate phase current level for step x given in % of IBase.
tx: Definite time delay for step x. The definite time tx is added to the inverse time when
inverse time characteristic is selected. Note that the value set is the time between
activation of the start and the trip outputs.
TDx: Time multiplier for inverse time delay for step x.
IMinx: Minimum operate current for step x in % of IBase. Set IMinx below Pickupx for
every step to achieve ANSI reset characteristic according to standard. If IMinx is set above
Pickupx for any step the ANSI reset works as if current is zero when current drops below
IMinx.
MultPUx: Multiplier for scaling of the current setting value. If a binary input signal
(enableMultiplier) is activated the current operation level is increase by this setting
constant. Setting range: 1.0-10.0
txMin: Minimum operate time for all inverse time characteristics. At high currents the
inverse time characteristic might give a very short operation time. By setting this
parameter the operation time of the step can never be shorter than the setting. Setting
range: 0.000 - 60.000s in steps of 0.001s.
