2 Description
General The device is used for the measurement/control of electrolytic conductivity,
resistivity or the TDS value. In addition, the JUMO AQUIS 500 CR offers the
option of displaying the measured conductivity according to a customer-
specific table.
Either 2-electrode or 4-electrode conductivity cells can be connected to the
device.
Temperature measurement is made through a Pt100/1000 probe and fed in as
a second input variable. This enables a specific, automatic temperature
compensation according to the measurement.
The device is operated by using keys and a large LC graphics display. This
display ensures that the measurements are clearly legible. The plain-text
presentation of the parameters makes it simpler for the user to configure the
device, and also helps in programming it correctly.
Thanks to its modular design, the device can be matched to the specific
requirements of the application. Up to four outputs are available (see the block
diagram for the functions).
Typical areas of
application Universal application in water and wastewater engineering, service/process water and wastewater, drinking water and well/surface water, pure and highly-
purified water applications, water for pharmaceutical purposes (e.g. to USP,
Ph.Eur. or WFI), water quality measurement and TDS measurement (ppm or
mg/liter).

Fitting sizes
The electrical connection must only be carried out
by qualified professional persons.
The choice of cable, the installation and the electrical connection must
conform to the requirements of VDE 0100 “Regulations on the Installation of
Power Circuits with Nominal Voltages below 1000 V” or the appropriate local
regulations. Only flexible cables and wires shall be used!
If contact with live parts is possible while working on the device, it must be
completely disconnected from the electrical supply.
Load circuits must be fused for the maximum relay current in each case, in
order to prevent welding of the relay contacts in the event of a short circuit.
The electromagnetic compatibility conforms to EN 61326.
Run input, output and supply cables separately and not parallel to one
another.
Use shielded sensor cables with twisted conductors. Do not run these cables
close to current-carrying components or cables. Ground shielding at one end.
Sensor leads should be implemented as uninterrupted cables (not routed via
terminal blocks etc.).
Do not connect any additional loads to the supply terminals of the device.
The device is not suitable for use in areas with an explosion hazard (Ex areas).
Apart from faulty installation, incorrect settings on the device may also affect
the proper functioning of the subsequent process or lead to damage. Safety
devices independent of the device should therefore always be provided and
should only be capable of adjustment by specialist personnel.

5.3 Preparatory work
Opening the
device
✱Prior to opening, loosen all cable fittings (2) so that the cables are
moveable.
✱Push connection cable a little into the case so that enough cable reserve is
available for opening.
✱Loosen the 4 front-panel screws (1) of the case lid and pull them out as
much as possible.
✱Pull the lid to the front and then fold to the front. The user needs to be able
to easily open the lid. Do not use force while opening!
Closing the
device
✱When closing the device, pull the connecting cables to the outside while
the cable fittings are in a released state and make sure that the lines in the
inside of the device run properly. Pay attention to the corresponding
sheathing measurement to ensure strain relief and protection type (IP67) of
the cable fitting.
✱The user must be able to close the lid with the 4 screws without a high
degree of pressure.
✱Tighten cable fittings.

The connection cable between sensor and transmitter must be a shielded cable
with a diameter of 8 mm max.
The device contains a guide plate that ensures an optimum cable path. After
laying the cables, the cable cover (1) must be attached until it clicks, like
shown above. This is important to ensure the electrical safety!
The sensor cables are run to the plug-in screw terminals and must have a strain
relief.
The cable clip (3) must only be screwed down (see next page) by a 3.5x6.5 pan
head screw! A longer screw may cause a hazardous voltage to be contacted to
the shielding!
