2 Description
General The instrument is used for measuring/controlling the pH, ORP or NH3-
(ammonia) concentration. The function is switchable on the instrument itself.
Depending on the measured variable, combination electrodes (e. g. pH/ORP
combination electrodes, gas-sensitive sensors) or split versions (glass/metal
electrodes with a separate reference electrode) can be readily connected.
Temperature serves as the second input variable, measured by a Pt100/1000
probe, for example. It is therefore possible to implement automatic
temperature compensation for the pH and NH
3
variables.
The instruments are operated using unambiguous keys and a large LC
graphics display on which the measurements are clearly legible. The plain-text
presentation of the parameters makes it easier for the user to configure the
instrument, and also helps in programming it correctly.
Thanks to its modular design, the instrument can be perfectly matched to the
specific application requirements. 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, leakage
monitoring in refrigeration plant.

4.1 Installation notes
❏ 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.
❏ 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.
❏ Uses 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
instrument.
❏ The instrument is not suitable for use in areas with an explosion hazard (Ex
areas).
❏ Apart from faulty installation, incorrect settings on the instrument may also
affect the proper functioning of the subsequent process or lead to damage.
Safety devices independent of the instrument should therefore always be
provided and should only be capable of adjustment by specialist personnel.

Connecting the
cables
The electrical connection for the surface-mountable housing is easily
accessible when the instrument is folded out.
The connection cable between sensor and transmitter must be a shielded cable
with a diameter of 8 mm max.
The instrument contains a guide plate that ensures an optimum cable path.
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!
