External setting of the motor speed via voltage input:
Voltage input: analog 0V .... 10V DC (max. 24V !)
➨
Connect the black and the white wire ac-
cordingly to the terminal board ST1B (see
table above).
0V to 10V:
Linear increase of the motor speed (0 rpm (at
0V) to 2400 rpm (at 10V))
Pump will run smoothly only at motor speeds
higher than 200 rpm.
Internal setting of the motor speed via trimming potentiometer:
+
Ensure that no control signal is applied, e.g.,
by removing the white and the black wires
from the terminal board ST1B.
+
Supply the pump with the required supply
voltage of 24V DC.
Adjusting the motor speed with the trimming potentiometer:
Turning the trimming potentiometer to the right increases the motor speed
(maximum 2400 rpm);
Turning the trimming potentiometer to the left decreases the motor speed
(minimum 0 rpm). Pump will run smoothly only at motor speeds higher
than 200 rpm.
+
To stop pump, disconnect pump from DC voltage supply.
