1. The power source side is distinguished by S and the load side by L. Both sides should be connected with DC voltage
according to the polarity indication. When the polarity is reversed, voltage and current are measured as negative values.
2. DCM–50V module is supplied with control power by bus bar DC voltage in case of stand alone operation.
3. Number of DCM modu les that can be connected to Accura 2300[S] is limited to 10 modules 5 modules for each RJ12 port
4. Over/Under event is detected by monitoring 20ms voltage current aggregation data.
5. Aggregation data over 1 second is also provided. Refer to the aggre gation section of Accura 2300 S User Guide for details.
6. The minimum DC voltage for stand alone operation in DCM 50V module is 12V.
7. The measured value below the configured minimum measurement is treated as zero.
8. Current measurement values may cont ain errors as the temperature varies
9. Over event occurs when the measured value exceeds threshold 1 by time delay.
10. Under event occurs when the measured value exceeds t hreshold 1 and is above or equal to th reshold 2 by time delay
11. The operation for digital output type is as follows.
12. A pulse is defined as pulse period and pulse on time.
13. Conforms UL61010 1 standard.
