Figure 50. Stator Current Limiting
Low-Level Limiting
When the stator current exceeds the low-level setting
B
, the DECS-250N annunciates the elevated level. If
this condition persists for the duration of the High SCL Time setting, the DECS-250N acts to limit the
current to the low-level SCL Setting. The generator is permitted to operate indefinitely at or below the low-
level threshold.
High-Level Limiting
When the stator current exceeds the high-level setting
C
, the DECS-250N acts to limit the current to the
high-level value. If this level of current persists for the duration of the high-level time setting
D
, the DECS-
250N acts to limit the current to the low-level SCL setting.
Initial Delay
In the case of low- or high-level stator current limiting, the limiting function will not respond until an initial
time delay
E
expires.
