4.5.4.3 Threshold Menu Pe/IeCos> RECT
Delay Type
RECT
Displays threshold delay time type. Setting choices are:
DMT (definite time) RI for the electromechanical inverse
time curve, IEC-XX, RECT, CO2, CO8, IEEE-XX inverse
time delay curve and RECT curve.
If the user selects IEC curve the following menu is
displayed:
TMS
1.000
Displays TMS value for the curve.
The setting range is from 0.025 to 1.5, in steps of
0.025.
tReset
0.04 s
Displays setting value for the reset time.
The setting range is from 0 to 100 s, in steps of 10ms.
By pushing 2 the next window will display the Pe>>?
4.5.4.4 Threshold Menu Pe/IeCos> ANSI/IEEE
Delay Type
IEEE-EI
Displays threshold delay time type. Setting choices are:
DMT (definite time) RI for the electromechanical inverse
time curve, IEC-XX, CO2, CO8, IEEE-XX inverse time
delay curve and RECT curve.
If the user selects IEEE/ANSI curve, the following menu
is displayed:
TMS
1.000
Displays TMS value for the curve.
The setting range is from 0.025 to 1.5, in steps of
0.025.
4.5.4.5 Reset Threshold Menu Pe/IeCos> DMT/IDMT IEEE/ANSI
Reset Delay Type

Select between DMT (Definitive Time) and IDMT
(Inverse Time).
If the user selects DMT delay type, the following menu
is displayed:
tReset
1.00 s
Displays setting value for the reset time.
The setting range is from 0 to 100 s, in steps of 10ms.
