Modification of the DID is strictly prohibited.
3. Receiving the product
3.1 Inspecting the product
• Check the received consignment for completeness.
• Check the DID for damage.
• Install as soon as possible after unpacking.
• Do not install or connect damaged products.
3.2 Transporting the product
• Before transporting the DID, empty all pipes, hoses and flow
cells, remove the sensors and pack them separately.
• Observe the permissible ambient conditions. See section
12. Technical data.
• Transport the DID carefully, do not drop. Do not expose the
DID to strong impact, mechanical loads or vibrations.
• Keep the DID away from corrosive substances, vapours of
organic solvents, nuclear radiation and strong electromagnetic
radiation.
• Use the original packaging or equivalent to protect the DID
during transport.
WARNING
Electric shock
- Switch off the power supply before installation.
- IP65 only applies, if the housing cover and the
terminal compartment of the CU 382 are properly
closed, and the appropriate cable glands or
dummy caps are fitted.
- Installation must be carried out by qualified and
authorised persons.
4.1 Installation location
Correct installation is important for proper functioning of the DID.
• Make the DID easily accessible for all tasks.
• Provide sufficient space for all components of the DID.
• Avoid external interferences, such as electric and electromagnetic interferences by leakage current, earth fault of
pumps, electric motors, high voltage currents.
• Protect the DID from direct sunlight and rain.
• Provide a reliable power supply for the control unit.
See also section 12. Technical data and the manual "Sensors
V1".
4.2 Installation of the DID
DID with flow cell
All parts of the DID with flow cell are assembled on a mounting
plate with pre-drilled holes for quick and easy installation.
• Use spacers (min. 10 mm) for installation of the DID with flow
cell on a flat wall.
See also sections 8. Product introduction and 12.4 Dimensions.
DID with sensor for tank immersion
The CU 382 control unit of the DID with sensor for tank immersion
can be mounted directly on a wall. See also sections 8. Product
introduction and 12.4 Dimensions.
4.3 Hydraulic connection
See also the labels on the mounting plate as well as the sections
12. Technical data and 14. Appendix.
The maximum flow through the flow cell of the DID is limited by
the integrated flow restrictor.
Use a vented outlet or a pressure-loading valve to avoid siphon
effect. Do not install a shut-off valve in the outlet line.

2. Connect the Rp 1/2" hose adaptor fittings to the inlet and the
outlet.
– The Rp 1/2" hose adaptor fittings are included in the
standard delivery of the DID.
3. Assemble the inlet and the outlet hose as follows:
– Push union nut and tensioning ring across the hose.
– Push the cone part fully into the hose, see fig. 2.
– Attach the cone part with hose to the adaptor fitting.
– Tighten the union nut manually. Do not use tools.
Fig. 2 Connecting the inlet hose
Avoid high loads caused by long or heavy hoses hanging from the
outlet port of the flow cell. A strain-relief for the outlet hoses may
be required.
4.4 Installing the sensors
All sensors used in the DID are packed separately to avoid
damage. They have to be prepared before installation according
to the "Installation" section in the manual "Sensors V1" supplied
with the sensor.
• For installation of the sensors in the flow cell, see the manual
"Sensors V1" supplied with the sensors.
• As soon as the sensors are ready for operation, they must be
wetted.

6.2 Connecting the sensors to the CU 382 control unit
All sensors for the DID have plugs.
Sensors for immersion have fixed cables with plugs.
1. Make sure that the sensor plug and the socket of the CU 382
control unit are dry and clean.
– Otherwise communication errors may occur and the DID
might be damaged.
2. Connect the sensor to a compatible socket on the CU 382
control unit using the connection cable provided.
3. Cover the connectors that are not used with protective caps.
6.3 Connecting the valve for automatic cleaning
Only DID with sensor for tank immersion with valve for automatic
cleaning:
• Connect the valve to terminals 10 ("Valve", "12 VDC") and 11
(GND). See fig. 3.
• If an external cleaning signal is used, connect the signal line to
terminal 12 ("Clean In", minimum 5 V).
6.4 Connecting further inputs and outputs
Observe the supplier manuals when connecting actuator devices,
such as dosing pumps or regulators.
6.5 Connecting the CU 382 to the power supply
WARNING
Electric shock
- Switch off the power supply before connecting the
CU 382 control unit.
- IP65 only applies, if the housing cover and the
terminal compartment of the CU 382 are properly
closed, and the appropriate cable glands or
dummy caps are fitted.
- Electrical connection must be carried out by
qualified and authorised persons.
• Install an earth leakage circuit breaker for the power supply.
• If the installation is in an area prone to lightning strikes, install
surge protection.
• Use an AC power supply with an earthed conductor wire.
– PE: potential earth
• Connect the process medium (e.g. waste water) to the same
earth ground with less than 0.5 Ohm.
6.6 Start-up of the operating software
If the CU 382 control unit is connected to the power supply, it
starts up and shows the s::can logo for 5 seconds. At first start-up
or if the internal settings have been reset to default, the CU 382
control unit starts with the selection of the language. See also
section 9.3.7
After this, the parameter screen is shown and the most recent
information is displayed.
Select language...
.
6.7 Sensor initialisation
Every sensor that is connected to the CU 382 control unit must be
installed and initiated individually. This can be done using the
software-supported initialisation process.
• Connect only the sensor you want to initialise to the CU 382.
– An individual address is allocated to the initialised sensor.
If no sensor was connected before, the CU 382 jumps into the
"Add MODBUS sensor..." menu to check for connected sensors,
right after setting the language.

The DID is designed for online monitoring of water quality
parameters and offers control functions for these parameters.
The DID must be used in accordance with the instructions given
in this manual. The values mentioned in this manual must be
observed.
8.3 Functional principle
The CU 382 control unit has a display and 7 operating buttons on
the front. The operating software starts automatically when the
CU 382 is powered-on.
The CU 382 control unit collects and displays readings from all
sensors via a digital bus connection. The CU 382 control unit
includes a PID (Proportional-Integral-Derivative) controller. With
the PID controller and dosing units, a closed control loop can be
set up.
The hydraulic part of the DID manages the complete water flow
from the inlet to the outlet. This includes filtration, pressure
reduction, flow restriction and flow control. The DID comprises
specifically designed flow cells for mounting of the sensors and
appropriate sampling.
