Referenced to GND,
polarity protected.
4-20mA speed / flow
indication output
Current source output
referenced to GND.
Requires a load
resistance 100 to 330 Ω
for optimal results. Use
a >100 Ω resistor if using
with a DVM.

Supply
Protected 5V output. Can
supply up to 20mA. Can
be used with a resistor to
set Run/Stop or external
contact inputs high or can
supply low current loads
connected to either digital
output.

Colour refers to typical wire colour in readily available leads. Please confirm these
colours before connection as there is no guarantee all manufacturers will follow
this convention.
CAUTION
Do not connect multiple units in series; if pumps are to be daisy
chained then use the ‘Input Matched’ function - see 10.3.7 I/O
settings (Ds500+ only).
See Section 16. Ds500+ external connections for wiring
example.

8.4 Fitting the Cartridge
NOTE: If the unit is already powered on - refer to 10.3.3
Cartridge information.
1. Lift the cartridge lock, as shown.
2. I Insert the cartridge offset by 20°, as shown:
Figure 6. - Fitting a cartridge
3. Rotate the cartridge 20°CCW so that it ‘snaps’ into position.
4. Push the cartridge lever down to secure the cartridge.
8.5 Connections to the Cartridge
Ensure the tube to be connected is prepared with a square
end. In the following order, place on to the tube:
1. Port sealing nut
2. Clamp ring
(observe correct orientation)
3. Tube fitting
4. O-ring
NOTE:
Max internal diameter of
connecting tubes: 6.3mm.
