Definite time characteristics
11.1.1
Definite time operation
The DT mode is enabled when the
Operating curve type
setting is selected either as "ANSI
Def. Time" or "IEC Def. Time". In the DT mode, the
TRIP
output of the function is
activated when the time calculation exceeds the set
Trip delay time
.
The user can determine the reset in the DT mode with the
Reset delay time
setting, which
provides the delayed reset property when needed.
Figure 334:
Operation of the counter in drop-off
In case 1, the reset is delayed with the
Reset delay time
setting and in case 2, the counter
is reset immediately, because the
Reset delay time
setting is set to zero.
The
Type of reset curve
setting has no effect on the reset method when the
DT mode is selected, but the reset is determined solely with the
Reset delay
time
setting.
