INSTALLATION GUIDE

Environmental CO2 Remote Mount Sensor

Installer’s Speciﬁcations

Input Voltage 20 to 30VDC, 24AC Analog Output 4-20mA (clipped and capped)/0-5VDC/0-10VDC (selectable) Sensor Current Draw 100mA max. Operating Temperature Range 0° to 50°C (32° to 12 2°F) Operating Humidity Range 0-95% (noncondensing) Housing Material High impac t ABS plastic

CO2 Transmitter: Sensor Type Non-dispersive infrared (NDIR), diusion sampling

Output Range 0-2000 ppm or 0 -5000 ppm, user selectable Accuracy ±30 ppm ±5% of measured value Repeatability ±20 ppm ±1% of measured value Response Time <60 seconds for 9 0% step change when used with supplied 3 ft. sampling tube (AA50)

Relay Contac ts: 1 Form C 1A@30VDC, resistive; 30W max.

EMC Conformance: EN 61000-6-4:2001 Class B, EN 61000-6-1:2001 EMC Test Methods: CISPR 11:2004, IEC 61000-4-2:2001, IEC 61000-4-3:2002, IEC 61000-4-4:2004, IEC 61000-4-5:2001, IEC 61000-4-6:2004, IEC 61000-4-8:2001, IEC 61000-4-11:2004 EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper surge protection (EN 61000-6-1:2001 specication requirements). When directly measuring outside air, ensure that the air temperature reaching the sensor is between 0° and 50°C.

Note: Rough handling and transp ortation may cause a temporary reduction of CO2 sensor accuracy. With time, the ABC function will tun e the readings back to the correct accuracy range. The default tuning speed is li mited to 30 ppm per week.

WIRING

1. Feed control wire through conduit adapter and grommeted compression tting on the bottom of the housing.

2. Remove terminal blocks by pulling straight up on the green assemblies. Connect wires as shown at left, and push terminal blocks back in to black receptacles.

3. Tighten compression tting around control wire until sealed. Snap conduit adapter onto compression tting. Refer to specications for power requirements and relay rating.

4. Select mA or Volt output using selector switch.

OPERATION

The CRLSxx remote mount CO2 sensor ensures adequate ventilation using NDIR technology combined with a self-calibration algorithm. The device comes with a three-foot length of pickup tubing for easy installation. Output is eld selectable (4-20mA/0-5VDC/0-10VDC).

To operate the CRL, install onto a vertical mounting surface. Then apply power and congure (page 3).
