Offline and Online Curve Checkboxes. Checking these boxes displays a plot of the takeover-style, off-line
and on-line overexcitation limiter curves. Curve magnification is reset by the Reset Zoom button.
SCL
The SCL tab has two setting groups: Primary and Secondary. The Primary and Secondary buttons select
between the primary and secondary Stator Current Limiter settings. In the default logic diagrams provided
with the DECS-400, a contact input is used to select either the primary or secondary SCL settings.
SCL functions are shown in Figure 51 and described in the following paragraphs.
SCL - Initial Delay. The SCL does not respond until the Initial Delay has expired. A setting of 0 to 10 may
be entered in 0.1 second increments.
SCL – High SCL Level. This setting configures the high-level current setpoint for the stator current limiter.
A setting of 0 to 66,000.0 Aac may be entered in 0.1 Aac increments.
SCL – High SCL Time. This setting establishes the time limit for high-level current limiting by the stator
current limiter. A setting of 0 to 240.0 seconds may be entered in 0.1 second increments.
SCL – Low SCL Level. This setting configures the low-level current setpoint for the stator current limiter. A
setting of 0 to 66,000.0 Aac may be entered in 0.1 Aac increments.
