The ground is common for the ventilator and the heater (red, blue and brown). The CVF4 has an optional 8-
wire Kipp & Zonen cable for connecting the 12 VDC to the ventilator and heater.  
 
The tacho output provides a 5 Volt square wave signal. It can be connected to a data logger to (remotely) 
check proper operation of the CVF4. Ventilator and heater ground are separated but may be connected. 
Ventilator and tacho ground are connected via a 100 

Ω

 resistor. 

 
The nominal tacho output is 475 Hz ± 25%. 
 
Changes often indicate pollution of the filter (significantly higher frequency), or mechanical problems with 
ventilator (zero or significantly lower frequency). 
 
If sufficient power is available it is advised to use the heater in combination with the ventilator even in warm 
climates. The heater will prevent deposition of dew in the morning. 
 
Plug in the instrument data cable, connected to the data logger or SCADA system as described in its own 
manual, in the instrument. 
 
Plug the CVF4 power cable in the CVF4 socket.
