PRODUCT DESCRIPTION

Heating
A separate power source is required for heating in the NAV210 (supply voltage 24 V DC,
power output min. 40 W (cyclical)).
Heating begins when the internal temperature drops below 10 °C. It then continues for at
least three seconds. If the temperature continues to fluctuate around the 10 °C mark, then
the heating often runs for a shorter time.
Important
•
If the temperature is over 0 °C in the NAV210 during commissioning, the device
activates.
•
If the temperature is below 0 °C in the NAV210 during commissioning, the device must
first be heated before it activates.
•
If the temperature in the device drops below 0 °C during operation, the device continues
to run, but sends a telegram indicating that the minimum operating temperature has
been breached.
•
The minimum operating temperature of –30 °C (outdoor temperature) is guaranteed for
a wind speed of 0 m/s. Experience has shown that operation is possible at wind speeds
up to 0.5 m/s. At higher wind speeds the heat is transferred from the scanner too
quickly.
