can be enabled or disabled and will not affect other functions until the Fast Voltage
Recovery setting is exceeded.
The setting range is from 1.0 to 15.0 volts outside the normal band edges in 0.1 V
increments. Once the voltage is back in band, the instantaneous operation curve is
replaced by the normal definite or inverse time delay curve and setting. Subsequent
excursions outside the bandwidth will use the original time delay unless the voltage again
exceeds the Fast Voltage Recovery threshold setting.
When Fast Voltage Recovery is active, Overcurrent Blocking (Current limit setting) will
be bypassed should conditions require this block to be in effect. Fast Voltage Recovery is
not available if any paralleling method is active. If an Intertap delay is set in the control,
it will not be bypassed by this feature.
