The heating element humidifiers type HeaterLine 60-90 are
double units - they consist of two separate units. The control sig-
nal and the safety interlock signal are connected to the terminal
block of the first humidifier (the guidance humidifier). Between
the first and the second humidifier there has to be an electrical
connection (done by the customer): The second (slave) humidi-
fier receives a control signal and the forwarded (potential free)
safety interlock signal from the first humidifier.
The wiring for control signal and safety interlock signal for
humidifiers type HL60-90 is done as follows:
Terminal block Safety interlock
of the first signal
humidifier
control signal
connection
terminal block
of the second
humidifier
(slave)
The control of the second humidifer is normally a Basic control
consisting of mainboard and display plate with 5 LED. The con-
trol of the first humidifier can be a Basic, Comfort or Comfort
Plus. To change parameters at the control of the second humidi-
fier please also see chapter „Basic Control“ in this manual.
Please note that jumper A, B and C are not set - and this should
not be changed.
