Page 9: Installation Of Cda-44As
After inserting the CDA-44AS, turn ON the power switch and confirm the startup screen by referring the "DCS-100A Instruction Manual for EDX-100A." If the "Card Type" is displayed in the Slot No. column, the card is correctly installed. -
Page 10: Connection Method
When one end of the strain gage transducer is equipped with no plug, there are 2 ways for connecting the strain gage transducer to the CDA-44AS/45AS. One is to connect conductors to a plug in advance and the other is to connect by using a bridge box. - Page 11 NOTE ● The F terminal of each channel input for the CDA-44AS/45AS is intended for sensor ID signals. Connecting any other signal to this terminal may prevent the EDX-100A/EDX-2000A/EDX-3000A from recognizing all conditioners installed in the system. If the EDX-100A/EDX-2000A/EDX-3000A does not recognize the conditioners, the startup screen will display "UNKNOWN"...
- Page 12 NOTE ● Maximum Input Voltage Range for Measurement Do not apply an input voltage exceeding the range specified for the CDA-44AS/45AS. Failure to do so will pose the risk of electric shock, deteriorated performance and system failure. See the following precautions when measuring the DC voltage of a battery, power supply, etc.
