2 Description

General The device has two analog inputs and one binary input. The first analog input

is suitable for connecting standard signals (0 - 10 V or 0(4) - 20 mA), which can
be prepared by any transmitter or sensor (such as a 2-wire transmitter). Pt100,
Pt1000 or NTC/PTC resistance thermometers (up to 4 k ohms) can be
connected to the second analog input. The power supply for a 2-wire
transmitter is integrated in the device.

Input signals can be shown as numbers or as a bar graph on the graphic
display. Parameters are displayed in plain text for easily comprehensible and
secure operation.

With two optional relay switching contacts, it is possible to implement both
simple switching or alarm functions and demanding control tasks with P, PI,
PD and PID action. If required, the device can also be provided with two freely
configurable and scalable analog outputs (0 - 10 V or 0(4) - 20 mA).

The device is suitable, for example, for displaying, measuring and controlling:

• Free chlorine, chlorine dioxide, ozone, hydrogen peroxide and peracetic
acid, in combination with sensors as per data sheet 20.2630.

• The pH value or redox potential with 2-wire transmitters as per data sheet

20.2701.

• (Hydrostatic) liquid levels with 2-wire transmitters (level probes) as per data
sheet 40.2090 or data sheet 40.4390.

• Flow rate in conjunction with transmitters as per data sheet 40.6010.

• Two temperature measuring points.

• Most sensors and transmitters that output standard signals (0 - 10 V or
0(4) - 20 mA).

Because temperature measurement is integrated, temperature compensation
takes place quickly and precisely, which is particularly important for many
analytical measurements.

Key features • Display: pH, mS/cm, µS/cm, ppm, %, mV, etc.

Special visualizations can also be configured with the setup program.

• Large, backlit LC graphic display.

• A choice of display visualizations: large numbers, bar graph or trend
display.

• Integrated calibration routines.

• Calibration logbook.

• IP67 enclosure protection for surface mounting
IP65 enclosure protection for switch cabinet mounting

• Selectable languages: German, English, French; additional languages can
be loaded later through the setup program.

• Through the setup program: user-friendly configuration, system
documentation, subsequent loading of additional languages.

5.1 Installation instructions

The electrical connection must only be performed by
qualified personnel!

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.

8.1 Notes

During calibration, relays and analog output signals adopt their configured
states!

The sensors connected to the device should be cleaned and the device itself
calibrated, at regular intervals (subject to the measuring material).

8.2 General

The device provides three calibration options for adapting the JUMO AQUIS
500 AS to a sensor with a standard signal (e.g. a sensor for free chlorine):

- With one-point offset calibration, the zero point of the sensor is

calibrated, see section 8.3 "One-point offset calibration (zero point
calibration)", page 76.

- With two-point calibration, the zero point and slope of the sensor are

calibrated, see section 8.4 "Two-point calibration", page 78. This is the
recommended calibration for most sensors.

- With one-point final value calibration, the slope of the sensor is

calibrated, see section 8.5 "Final value calibration", page 80. This is the
recommended calibration for chlorine sensors, for example.

Start

- With one-point offset calibration, the zero point of the combination

electrode is calibrated, See section 10.3 "One-point offset calibration (zero
point calibration)", page 90. This is the recommended method if "mV" has
been configured as the UNIT.

- With two-point calibration, the zero point and slope of the combination

electrode are calibrated, See section 10.4 "Two-point calibration", page 92.
This is the recommended method if "%" or "CUSTOMIZED" has been
configured as the UNIT.

- With one-point final value calibration, the slope of the combination

electrode is calibrated. This calibration is not recommended for redox
measurements!

11.1 Notes

During calibration, relays and analog output signals adopt their configured
states!

The sensors connected to the device should be cleaned and the device itself
calibrated, at regular intervals (subject to the measuring material).

11.2 General

Requirement A conductive conductivity cell delivers a standard signal to the JUMO AQUIS

500 AS either via an external transmitter provided by the customer or via a
transmitter integrated in the measuring cell.
If the signal is not yet temperature compensated, or if there are measurement
errors because of cell constant deviations, the JUMO AQUIS 500 can take on
the task of temperature compensation and/or cell calibration.

The device provides two calibration options for adapting the JUMO AQUIS
500 AS to conductive conductivity cells:

- Calibration of the relative cell constants; this is a one-point

calibration, see section 11.3 "Calibrating the relative cell constant", page

96.

- Calibration of a linear temperature coefficient; this is a two-point calibration,

see section 11.4 "Calibrating the temperature coefficient of the
measurement solution", page 98.

Start

- Calibration of a non-linear temperature coefficient. Here the temperature

coefficient is calibrated at six points, see section 11.4 "Calibrating the
temperature coefficient of the measurement solution", page 98.

Calibration can be started as follows:

if this has been enabled in ADMINISTR. LEVEL / PASSWORD / CALIB.
ENABLE.

- Via ADMINISTR. LEVEL / PASSWORD / CALIB. LEVEL

- Via CALIB. LEVEL

if this has been enabled in ADMINISTR. LEVEL / PASSWORD / CALIB.

The LC display now shows the chosen working temperature (flashing) (2).
✱ Press the key.

The conductivity (399 µS/cm) at the current temperature (24.3°C) now appears
on the right of the LC display.
The temperatures T1 (25°C) and T2 (70.0°C) that have yet to be
triggered are shown on the left.

✱ Press the key.
✱ Heat the measuring material until the working temperature is reached.

During calibration, the rate of temperature change in the measurement
solution must not exceed 10 °C/min.

Calibration is also possible in the cooling process (with a falling temperature).
It starts above the working temperature and ends below the working
temperature.

As soon as the temperature of the measuring material exceeds T1 (25°C), this
is hidden on the display. The uncompensated conductivity at the current
temperature is displayed on the right.
