Function and features1
The airflow monitor monitors airflows. It senses whether there is a preset airflow
(= green LED lights, output relay energised for NO function, de-energised for NC
function).
If the flow is below the preset value, the red LED lights. The output relay is de-
energised for NO function and energised for NC function.
Setting range 1 m/s to 10 m/s.•
Start-up delay of 3 s ... 60 s (to suppress short-time fluctuations), depending on•
the preset value
Mounting2
Mount the airflow monitor by means of the mounting clamp provided. Diameter of
the mounting hole for the unit: 24 mm. If mounting is to be airtight, use the gasket
provided. The sensing head must be completely immersed into the airflow and
should be in the range of the highest flow velocity, if possible. Installation depth:
min. 32 mm, max. 120 mm.
min. 32 mm max. 120 mm
Align the unit in the airflow; the arrow on the cap must point in the direction of flow.
