The control can be adjusted to the following external control sig-
nals:
0(2) - 5 V DC
0(2) - 10 V DC
0(4) - 20 V DC
0(4) - 10 mA DC
0(4) - 20 mA DC
0 - 140 Ohm
The factory setting is a control signal of 0-10V.
The steam humidifier typically switches off with a (control) sig-
nal of less than 20% and displays "No demand", i.e. no steam is
produced. With a (control) signal of 25% the humidifier resumes
operating.
With a signal of 20%, humidification output reaches 5% of max-
imum output for HeaterLine humidifiers and 10% for electrode
humidifiers. Below that, the unit switches off. At lower steam
output levels, steam would condense in the cylinder or steam
hose and fail to reach its intended location.
