- Accuracy: 0…20 %CO2
- Medium: Air & non-aggressive gases
- Long-term stability: 60 s
- Measurement range: 0…20 %CO2
Product Usage Instructions
Installation and Setting
- CCA-S-20X probe only: Connect to E2-01XX cable for power and analog signal readout. Align catches correctly and tighten the knurled nut by hand.
- CCA-S-20X-SET probe and converter box: Connect the probe to the converter box cable, align catches, tighten the knurled nut, and power the probe via the converter box using the supplied power supply.
Positioning of the CO2-Probe
- Find a suitable place for measurement, avoiding sunlight and heat sources. Connect the sensor to a data logger or use an extension cable E2-XXA up to 5 m. A wall-mounted holder, AC1322, is available for purchase.
Integration of the CO2-Probe into RMS
- The CCA-S-20X-SET can only be integrated into RMS with RMS-MADC868/915-A or RMS-ADC-L-R data loggers. Refer to the respective user manual for adding the data logger to RMS.
Adjustment / Calibration
- The probes are factory-adjusted. For optimal accuracy, Rotronic recommends annual calibration of the probes.
GENERAL DESCRIPTION
- Congratulations on your purchase of the CO2-probe. Please read these short instructions carefully before installing the device. This document is limited to a description of the main functions and installation of the device.
- Further documents can be found on the internet at: ProcessSensing.com or rotronic.com.
DIMENSIONS/CONNECTIONS
INSTALLATION AND SETTING
The installation of the CCA can be carried out in two ways:
- CCA-S-20X probe only: a cable is required (E2-01XX) to power and read out the analog signals from the device. When connecting to the E2-01XX cable, make sure that the catches are aligned correctly. Tighten the knurled nut by hand.
- CCA-S-20X-SET probe and converter box: When connecting the CCA-S-20X probe to the cable from the converter box, make sure that the catches are aligned correctly.
- Tighten the knurled nut by hand. Power the probe via the converter box with the power supply delivered with the set. Plug the power supply into the mains connection.
POSITIONING OF THE CO2-PROBE
- Look for a representative place for the measurement. Avoid interfering influences such as sunlight, heating elements, etc.
- The sensor can be easily connected to the data logger or can be connected with an extension cable E2-XXA up to 5 m. It is possible to purchase a wall-mounted holder, AC132,2, for the probe.
INTEGRATION OF THE CO2-PROBE INTO RMS
- Attention! The CCA-S-20X-SET can only be integrated into RMS with the RMS-MADC-868/915-A or the RMS-ADC-L-R data loggers. Please see the respective short user manual to add the data logger to RMS.
- The CCA-S-20X-SET offers a 4…20 mA output.
The cabling for the 4…20 mA output:
- Blue: negative (-)
- Brown: positive (+)
ADJUSTMENT/CALIBRATION
- The probes are adjusted in our factory before delivery. For maximum accuracy, Rotronic recommends an annual calibration of the probes.
