Figure 7 - Internal speed setting
3.2
Configure the XDD1 24V dc internal speed setting
There are two internal speed settings, use the following procedure to adjust the internal speed control (refer to
).
Remove the screw which secures the cover to the circuit board (refer to
, item1) Move the cover carefully
and only as far as necessary. Using a screw driver, turn the potentiometer to one of two positions. Set to position 2
for normal speed or position 3 if maximum throughput is required (refer to
). Assemble the cover in reverse
order.
3.3
Configuring the XDD1 24V dc for external analogue (0 - 10 V)
speed control
Remove the screw which secures the cover to the circuit board (refer to
, item1) Move the cover carefully
and only as far as necessary. Using a screw driver turn the potentiometer anti-clockwise to position 1 (refer to
). Assemble the cover in reverse order. Apply external analogue 0-10 V signal for motor speed control.
Voltage input: analogue 0 V....10 V
Note:
Pump runs smoothly only at speeds > 200 rpm ( > ~0.9 V).
<0.5 V
: Pump stopped
0.5 V to 10 V : Linear increase of the motor speed (~100 rpm to 2200 rpm)
