• Definite time operation (DT): gives the TRIP signal after a user-defined time delay regardless

of the measured or calculated voltage as long as the voltage is above the

U

set

value and

thus the pick-up element is active (independent time characteristics).

• Inverse definite minimum time (IDMT): gives the TRIP signal after a time which is in relation

to the set pick-up voltage

U

set

and the measured voltage

U

m

(dependent time

characteristics).

The IDMT function follows this formula:

Where:

t = operating time

k = time dial setting

U

m

= measured voltage

U

s

= pick-up setting

a = IDMT multiplier setting

The following table presents the setting parameters for the function's time characteristics.

Selection of the delay type time counter. The selection possibilities are

dependent (IDMT, Inverse Definite Minimum Time) and independent

(DT, Definite Time) characteristics.

Definite time operating delay. The setting is active and visible when DT

is the selected delay type.

When set to 0.000 s, the stage operates as instant without added delay.

When the parameter is set to 0.005...1800 s, the stage operates as

independent delayed.

Resetting time. Time allowed between pick-ups if the pick-up has not led

to a trip operation. During this time the START signal is held on for the

timers if the delayed pick-up release is active.
