10.3.2.2 Continuously variable power module type ...16V
The continuously variable speed controller offers the option of controlling
the fan motor either via a 0-100 KΩ potentiometer, a 0-10 V DC signal or a
0-5 V DC signal. The type of control is pre-set by a jumper/pin.
To guarantee a reliable start up, the fan is operated for 30 seconds at
120 V AC. A minimum voltage limit of 100 V AC is factory-set,
The maximum limit can be selected via the DIP switch (see table 1)
The fan and the power module can be disconnected from the mains power
supply via the integral master switch.
All additional electrical components are not disconnected from the mains
power supply by the master switch!
