1. General instructions
Warning! The analogue signal isolators of the WAVEANALOGUE PRO series
may only be installed by qualified personnel. Be sure not to
connect the unit to power supply before appropriate installation.
Do not select ranges during operation, because live parts are
exposed during this process. Only use a screwdriver which is
properly insulated against the voltage applied to the input when
fine adjusting the potentiometers on the front.
Be sure to observe the national regulations for installation and
selection of cables.
Appropriate safety measures against electrostatic discharge
(ESD) should be taken during assembly and adjustment work on
the WAVEANALOGUE PRO.
2. Application
Analouge singnal isolators are used for galvanic isolation and conversion of
temperature, resistance and potentiometer signals. Input and output
signals are factory set according to type or can be calibrated/switched via
DIP switches. It is not necessary to adjust the measurement range.
A +/- 5% variation can be achieved in the respective range by connecting
potentiometers for zero and span. The transmitted measurement signal is
linear to the measured temperature.

3. Configuration
3.1 Equipment
A screwdriver with a width of 2.5 mm is required to adjust the unit and to
connect the wires to the terminals.
3.2 Opening the unit
Disconnect the plugs. Disengage the top part of
the housing by carefully pressing the latches on
both sides (1). Pull out the top part of the hous-
ing and the electronics section until they lock (2).
3.3 Settings
Set input and output ranges, minimum input values
and measuring span via the DIP switches SW1 and
SW2 according to the following tables.
When activating variable setting SW 1/8 of the span
or offset, it is possible to make additional adjust-
ments via front potentiometers span and offset,
accessible below cover (3)
Caution! Only use a screwdriver which is
properly insulated against the voltage
applied to the input when fine adjusting
the potentiometers on the front.
