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).

NOTE: This pr oduct is fac tory calibrat ed. The typical CO2
sensor c alibration inter val is 5 years, depe nding on specic s ite
install ation factor s. As of the date of this d ocument, complia nce
with ANSI/ASHR AE 62-2001 requi res minimum on-si te accuracy
verica tion intervals o f 6 months, or per the bu ilding operatio n and
maintenance manual. Accuracy verication should be perfo rmed
using eith er a comparison to a kn own reference or a CO2 gas
calibra tion kit available f rom Veris Industr ies (model AA01).

WARNING: CO2 sensor calibration requires gas calibration kit.
Perfor ming calibrati on without gas kit w ill cause errone ous
readings. Consult factory for calibration kit.

CALIBRATION PROCESS

1. Connect hose to plastic port located on sensing module.

2. Start owing nitrogen gas (0 ppm CO2 only).

3. Enter Calibration mode as described on page 3.

Calibrate for 5 min. Unit will return to

working display when finished.

ABC (Automatic Baseline Calibration) is a patented self-calibration feature that
automatically adjusts the CO2 sensor to compensate for drift. When ABC is enabled,
the lowest reading within every 24-hour period is recorded and analyzed over
a running 7 day or 28-day period. If a statistically signicant amount of drift is
detected, an automatic correction factor is applied. This enables the sensor to operate
within specications for the 5-year calibration interval.

NOTE: After changing the ABC settings, the unit will need to be power cycled for the
changes to take eect.
