Connection of sensor 2 to the NivuSonic CO
Improper connections which lead to higher transition resistance or the use of
other cables may lead to disturbance and errors in the measurement.

NivuSonic CO Power Supply
Depending on the type of NivuSonic CO k used, it can be supplied with 85-
260 V AC. Also possible is a 24 V DC supply (see chapter 4.4).
The two slide switches located above the terminals serve as additional power
switch.

A transmitter with 24 V DC cannot be operated with alternating current, just as
it is impossible to operate a 230 V AC transmitter with direct current.
During AC operation the DC supply clamps b2 and b3 provide an auxiliary volt-
age of 24 V DC with a maximum rating of 100 mA (turn on 24 V-switch!). If using
this auxiliary voltage (e.g. for feed control signals to digital inputs) please ob-
serve not to loop it through the entire switching circuit in order to keep the risk of
inductive interference as low as possible
