Please observe local regulations for the disposal of the device. For disposal, the individual components of the device must be separated according to local recycling regulations. -
Page 6: Product Description
3.2 Dimensions. The electronics of CDS201 is located in the front cover, which can be easily snapped on/off once the back cover is fixed onto the wall and wired. The back cover contains just the push-in terminals. No tools are needed for mounting or changing the active part. -
Page 7: Dimensions
Electrical Connection 0.20 30 / 1.18 For connecting the power supply and the outputs, the CDS201 features push-in spring terminals for max. 1.5 mm (AWG 16). The cables are fed into the enclosure via the rear side. WARNING Incorrect installation, wiring or power supply may cause overheating and therefore personal injuries or damage to property. -
Page 8: Display
24 V AC ±20 % NOTICE The supply GND and the measurement GND of the CDS201 with voltage output must be wired separately. Output: 0-5 V For failure-free operation and performance according to the specifications, the supply GND and the 0-10 V measurement GND of CDS201 with voltage output must be wired separately. -
Page 9: Mounting And Installation
User Manual CDS201 4 Mounting and Installation As the room sensor is generally mounted onto a conduit box, for accurate measurement results it is important to tighten the conduit box for avoiding false air ingress (along the electrical tubes inside the wall) into the room sensor enclosure. -
Page 10: Setup And Configuration
30 (1.2) 5 Setup and Configuration The CDS201 is ready to use and does not require any configuration by the user. The factory setup of CDS201 corresponds to the type number ordered. Please refer to the datasheet at www.epluse.com/cds201. While the room sensors with analogue output do not provide a configuration interface, the digital versions offer some options for customization. -

4074 0xFE9 1) The choice of measurement units (metric or non-metric) must be done according to the ordering guide, see CDS201 datasheet. Switching from metric to non-metric or vice versa by using the PCS10 is not possible. 2) Register number starts from 1 3) Register address starts from 0 4) Examples: For scale 100, the reading of 2550 means a value of 25.5. -
Page 15: Device Status Indication And Error Monitoring
Device Status Indication and Error Monitoring Modbus The CDS201 features a status register which contains all status and error information. It is possible to read it from Modbus register 602 (0x259). If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or to 0x8000 (INT16). - Page 16 In the event of a serious error, the “Present Value” of each Analogue Input Object is set to NaN and “Reliability” is set to NO_SENSOR. The „Event State“ Property is set to FAULT. Please refer to the CDS201 PICS (Product Implementation Conformance Statement) at www.epluse.com/cds201. , Humidity and Temperature Room Sensor | 17...
