Installation and operating instructions
9.3.2.2 Continuously variable power module type ...31V
The continuously variable speed controller offers the option of
controlling the fan motor either via a 0-100 KΩ potentiometer,
0-10 VDC signal or 0-5 V DC signal. The type of control is
pre-set by a jumper.
To guarantee a reliable start up, the fan is operated for 30
seconds at 120 VAC. A minimum voltage limit of 100 VAC is
factory-set.
The maximum limit can be selected via the DIP switch.
Models 44, 45 and 46: (see Table 1)
Model 47: (see Table 2)
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!
