210-2000

Span

The Span parameter determines whether you want to measure concentrations between 0-2000 ppm or 0- 5000 ppm. If set to 2000 ppm, the sensor’s analog output signal will be scaled properly so that the highest output voltage corresponds to 2000 ppm. Likewise, if set to 5000 ppm, the highest output voltage will signify 5000 ppm. Press ENTER to save settings.

Output

The Output parameter determines whether you want the analog output voltage to vary from 0- 5VDC or from 0-10 VDC. This parameter must be set to 0- 5VDC if the analog output is connected to an I/O board’s input point. Press ENTER to save settings.

Replacing the Door

Once all programming and wiring is done, the sensor is ready for operation. Snap the door on to the front of the circuit board to complete installation. The sensor comes equipped with two doors: one with a window that allows the screen to be shown, and one with no window that covers the screen. Choose whichever door is appropriate for your site.

Setting Up The Sensor

Type in Einstein and

REFLECS Controllers

The analog output of the CO2 sensor is a linear 0- 5VDC signal, with 0V representing a concentration of 0 ppm, and 5V representing the maximum concentration level (either 2000 ppm or 5000 ppm, depending on the value of the Span parameter you chose when setting up the sensor).

In order for Einstein and the REFLECS line of controllers (RMCC, BEC, or BCU) to read the signal from the CO2 sensor, it must be set up under Sensor Control (for REFLECS) or the Analog Input Setup Screen (for Einstein) as a Linear sensor. Refer to your controller’s user manual for more information on the Linear sensor type and how to program its parameters.

When setting up the sensor in Einstein or REFLECS, you will need to include the following information:

Gain: The Gain is the number that will be multiplied with the number of volts coming from the CO2 sensor’s analog output to yield the concentration value. If the sensor’s Span is set to 5000 ppm, use a Gain value of 1000. If the Span is set to 2000 ppm, use a Gain value of 400.

Offset: Because all calibration is handled by the sensor itself, the CO2 sensor’s offset should be set to zero.
