Description
Pick-up V/Hz >
(% of nominal)
0.01…30.00%
0.01% 5.00%
The maximum allowed increase in the measured V/Hz ratio in
relation to the nominal V/Hz ratio.
Alarm delay (DT)
0.000...1800.000s 0.005s 0.040s
The definite operation time delay for alarm event.
Delay type
0: DT
1: Inverse
2: DT and inverse
-
0: DT
Selects the delay type(s) for the time counter.
Time dial setting k 0.01...65.00
0.01
0.01
Defines the time dial/multiplier setting for inverse
curve characteristics.
This setting is active and visible when the "Delay type"
parameter is set to "Inverse" or "DT and inverse".
Definite operating
time delay
0.000…1800.000s 0.005s 0.040s
The definite operating time delay which is applied no matter
how much the V/Hz ratio is exceeded.
This setting is only visible, when the selected delay type is "DT"
or "DT and inverse".
The pick-up activation of the function is not directly equal to the START signal generation of the
function. The START signal is allowed if the blocking condition is not active.
Inverse operating time characteristics are calculated according to the following equation:
