Delay Type
DMT
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 DMT the following menu is displayed:
t Pe>
150.00 s
Displays setting value for the trip threshold.
The setting range is from 0 to 150s, in steps of 10ms.
tReset
0.10 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>>?
