1 Product description
DOL 139 is a sensor for measuring carbon dioxide/CO2, relative humidity and temperature. The sensor is in-
tended for measurement in live-stock house and industrial environments.
The sensor is protected by a sturdy casing and behind a carefully selected filter. The sensor is supplied with ca-
ble and a protection cap for protection of the sensor during washing and disinfection.
The sensor must be placed in the middle of the house.
1.1 Accessories
140261 DOL 119/139 protective cap, silicone (5 pcs.)
Protection cap for DOL 119/139 for protection of the sensor during, for exam-
ple, cleaning.
301241 Cable 2m 5xAWG 22 UL2464, M12 female plug
2m cable for sensor mounting.
2 Installation
The sensor must be mounted freely hanging in the cable.
Remember that the protection cap must be mounted on the cable before the cable is mounted.

Free air passage around the tip of the sensor.
Mount the sensor so it is not exposed to direct sunlight, as this would
affect the measurement.
The sensor must warm up for 10 minutes after power on.
After the sensor has been exposed to water and condensation or high humidity for a long period of time, it re-
quires a period where the relative humidity is lower than 80% in order for it to measure correctly.
3 Connection
Installation, servicing and troubleshooting of all electrical equipment must be performed by quali-
fied personnel in accordance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.

Connection to iDOL 63 Cloud Gateway
DOL 139 can be connected to iDOL 63 which has 8 ports for sensor connections.
If you have purchased the PRO app or access via Web-UI, you can configure the ports freely and choose
which ports are used for the sensors.
We recommend that DOL 139 is connected to iDOL 63 with the following connections
• IN1: CO2 (gray)
• IN3: Relative humidity (white)
• IN4: Temperature (black)

Each port works separately and must be configured separately via Omni Cloud to the connected sensor. Follow
this procedure to connect DOL 139:
1. Make sure power is disconnected from iDOL 63.
2. Select the port to be used.
3. Follow the instructions in this manual for correct connection of power, signal and ground connection.
4. Connect POE (power and internet) by means of the RJ45 internet plug.
5. Update Onmi Cloud with information about the sensors connected to the individual ports. Follow the instruc-
tions in the Omni UI User Guide or pass the information on to the owner/administrator of the Omni Cloud
account.

6 Maintenance
Figure 5.
Clean the sensor with water and a brush without using:
• High-pressure cleaner
• Highly compressed air
• Solvents
• Corrosive/caustic agents
• Alcohol-based disinfectants
During cleaning and disinfection, the sensor should be removed and
the sealing plug for the cable should be mounted. Alternatively, the
sensor protective cap can be mounted. The sensor must be placed
with the tip pointing upwards during disinfection.
