Input configuration
Parameter Description
IP 00 Not used
IP 01 CI1: Samples taken for averaging control signal
IP 02 CI1: Calibration
IP 03 CI1: Minimum CO2 range ppm
(CO2 level when output is at its minimum)
IP 04 CI1: Maximum CO2 range ppm
(CO2 level when output is at its maximum)
IP 05 CI1: Enable ABC automatic CO2 background calibration
IP 06 CI1: Calibrate CO2 sensor
Note: For normal operation, calibration is not required. Only experts
should calibrate the sensor.
0 = No calibration (default)
1 = Calibrate to gas (0 ppm)
2 = Calibrate to fresh air (400 ppm)
4 = Calibration error (status)
1) Sample interval: 1 sec.
Output configuration
Parameter Description
OP 00 AO1 (CO2): Configuration of output signal:
0 = CO2 value
1 = Recorded minimum CO2 value
2 = Recorded maximum CO2 value
OP 01 AO1 (CO2): Minimum limitation of CO2 output signal
OP 02 AO1 (CO2): Maximum limitation of CO2 output signal
2) The Output signal will be scaled according to selected input range, selected limitation of output signal and the output
signal range selected by the jumper.
3) If the default values are changed, the position of JP2 has no influence and the output signal range defined with the
parameters applies.
IP = Input Parameter
OP = Output Parameter
CI = CO2 Input
AO = Analog Output
Examples of CO2 output signal on AO1:
Output signal type = Voltage (JP1 jumper setting)
Output signal range = 0...10 VDC (JP4 jumper setting)
Default setting
IP 03 = 0 ppm, IP 04 = 2000 ppm (range)
OP 00 = 0 (CO2 value)
OP 01 = 0 % (limitation)
OP 02 = 100 % (limitation)
Output
