External actuation functions are available only in the RC version.
Connection details and technical data are provided in Chapter 3.9
8.1 External actuation analog input
The analog input can be used to externally control a pump flow rate
from (0%) 15% to 100%.
The analog input must be activated by connecting the RC cable.
➔
With the RC cable connect the white lead (jumper) to the grey
lead (ground) or with the RC connector, connect pin 2 to pin 5.
See Fig. 18
➔
If external actuation is switched on, this is indicated on the pump
by the illuminated "EXT" symbol.
See Fig. 19
When the analog input is active, the pump can be started only if a
valid analog signal is present.
The control knob is deactivated. Manual flow rate entry is blocked.
