Control via 0-100 KΩ potentiometer
When controlling using a 0-100 KΩ potentiometer (linear),
the jumpers for models 44, 45 and 46 and the DIP switches 1
and 2 for model 47 need to be wired/set at the potentiometer
(Models 44, 45 and 46, see Fig. 1, Model 47 see Fig. 4) on the
master unit (the TOP connected to the potentiometer). All
additional TOP (slave units) then need to have the jumper and/
or DIP switch position 0-5 V. (Models 44, 45 and 46 see Fig. 3,
Model 47 see Fig. 6).
Control via 0 - 10 VDC
When controlling using 0-10 VDC, the jumpers for models 44,
45 and 46 and the DIP switches 1 and 2 for model 47 need to
be wired/set at 0-10 V on all power modules (Models 44, 45 and
46, see Fig. 2, Model 47 see Fig. 5). The 0 - 10 V control signal
is interpreted with respect to its speed according to the table
(refer to table 3). Input resistance see Table 4.
Control via 0 - 5 VDC
When controlling using 0-5 VDC (e.g. on-site control), the
jumpers for models 44, 45 and 46 and the DIP switches 1 and
2 for model 47 need to be wired/set to 0-5 V on all power
modules (Models 44, 45 and 46, see Fig. 3, Model 47 see Fig. 6).
The speed does not behave linear to the control voltage with
this setting.
Input resistance see Table 4.
