INTELLIGENT AIR QUALITY
DUCT SENSOR
The -F version of the product is not suited for 3-wire connection. It has separate
grounds for power supply and analogue output. Connecting both grounds together
might result in incorrect measurements. Minimum 4 wires are required to connect
-F type sensors.
The -G version is intended for 3-wire connection and features a ‘common ground’.
This means that the ground of the analogue output is internally connected with
the ground of the power supply. For this reason, -G and -F types cannot be
used together on the same network. Never connect the common ground of -G
type articles to other devices powered by a DC voltage. Doing so might cause
permanent damage to the connected devices.
ATTENTION
MOUNTING & OPERATING INSTRUCTIONS IN STEPS
Before you start mounting the unit, read carefully
“Safety and Precautions”
.
The sensor is not designed, manufactured or intended for control or monitoring
equipment in environments requiring life safety performance, in which the failure
of the sensor could lead directly to death, personal injury or severe physical or
environmental damage.
NOTE
The compounds released from plastics may influence the sensor readings. Please
allow several days for the sensor to stabilize before you obtain the accurate
values.
NOTE
Follow these steps:
1.
When preparing to mount the unit, bear in mind that the probe opening must be
positioned in the centre of the duct. Always use the flange to install the sensor on
round ducts. It is possible to install the sensor without the flange on rectangular
ducts (if necessary), see
