10.1.2 Time Parameter
Two dependent time protection types can be selected and a time multiplier modifies the basic trip time
characteristic. There are eighteen (18) time multiplier settings that can be selected ranging from 0.005
times to 1.0 times (see Section 13, User Adjustable Settings).
Settings 0.005, 0.01, 0.015, 0.02, 0.03 and 0.04 are positioned after
setting 1.0 in the stored setting’s list (Level 9, Position 4).
10.1.3 Viewing the Instantaneous Current
The instantaneous current in each of the three phases can be displayed on the RDM (Level 5, Position
1). The three phase currents are displayed, as a % of the overload set current. The average current
value is expressed in Amps and is displayed at Level 5 and the Status Page (Level 0, Position 0).
