Operation
AC Current Sensing:
The AC input voltage must be applied to the CSRA continuously during operation. The power up time delay is provided to allow for the inrush current of a motor and does not affect the CSRA’s output contact during this time. The CSRA will remain in the de-energized state during the power up time delay. A nuisance trip delay is activated after the power up delay to avoid “nuisance” trips.
Over Current Mode (Auto Reset):
If the current through the CSRA is greater than the current set point adjustment for longer than the nuisance trip time delay, the relay will energize. The output relay will stay energized until the current drops below the current set point adjustment, at which time the output relay will become de-energized.
Under Current Mode (Auto Reset):
As long as the current remains greater than the set point, the relay will remain de-energized. When the current drops below the current set point adjustment for longer than the nuisance time delay, the output relay will become energized.
