4.7 Operating modes
Note: The displayed l and ml values are only reliable
if the pump has been calibrated to the actual installa-
tion, see section 6.
The pump can run in three different operating
modes:
• Manual
• Pulse
• Analog
See description in the following sections.
4.8 Manual
The pump is dosing as constantly and evenly as pos-
sible, without any external signals.
Set the quantity to be dosed in l/h or ml/h. The pump
automatically changes over between the measuring
units.
Setting range:
DMS 2:
25 ml/h - 2.5 l/h
DMS 4:
40 ml/h -
4 l/h
DMS 8:
75 ml/h - 7.5 l/h
DMS 12: 120 ml/h - 12 l/h

4.9 Pulse
The pump is dosing according to an external pulse
signal, i.e. a water meter with pulse output or a con-
troller.
Set the quantity to be dosed per pulse in ml/pulse.
The pump adjusts its capacity according to two fac-
tors:
• Frequency of external pulses.
• The set quantity per pulse.
Setting range:
DMS 2: 0.00230 ml/pulse - 50 ml/pulse
DMS 4: 0.00370 ml/pulse - 80 ml/pulse
DMS 8: 0.00695 ml/pulse - 150 ml/pulse
DMS 12: 0.01110 ml/pulse - 240 ml/pulse

Actual capacity
in ml/h or l/h
Fig. 7
If the set quantity per pulse multiplied by the pulse
frequency exceeds the pump capacity, the pump will
run at maximum capacity. Excess pulses will be
ignored and the "actual capacity" display will flash.
4.10 Analog
The pump is dosing according to an external analog
signal. The dosed quantity is proportional to the input
value in mA.
4-20 (default):
4 mA =
20 mA = 100%.
20-4:
4 mA = 100%.
20 mA =
0-20:
0 mA =
20 mA = 100%.
20-0:
0 mA = 100%.
