Table 4.2.3.4-32 Operating time characteristics setting parameters.
Name Range Step Default Description
Delay Type DT
IDMT
- DT Selection of the delay type time counter.
Selection possibilities are dependent
(IDMT, Inverse Definite Minimum Time)
and independent (DT, Definite Time)
characteristics.
Definite operating
time delay
0.000…1800.000 s 0.005 s 0.040 s Definite time operating delay. Setting is
active and visible when Delay Type is
selected to DT.
When set to 0.000 s the stage operates as
instant (PIOC, 50) stage without added
delay. When the parameter is set to 0.005
– 1800 s the stage operates as
independent delayed (PTOC, 51).
Delay curve series IEC
IEEE
- IEC Setting is active and visible when Delay
Type is selected to IDMT.
Delay curve series for IDMT operation
following either IEC or IEEE/ANSI
standard defined characteristics.

- NI Setting is active and visible when Delay
Type is selected to IDMT.
IEC standard delay characteristics.
Normally Inverse, Extremely Inverse, Very
Inverse and Long Time Inverse
characteristics. Param selection allows the
tuning of the constants A and B which
allows setting of characteristics following
the same formula as the IEC curves
mentioned here.
