Galltec+mela EDJ-3-U Manual

Description
The controller EDJ-3 for humidity and temperature con-
sists of two integrated, digital microprocessor controllers
and also an integrated 24-VDC power supply for the
sensors.
The humidity temperature sensor type e.g. D Series or
A/B Series is used as the readings recorder (please
control output signal!). The humidity and temperature
values are displayed digitally on the EDJ-3 controller as
actual values.
The EDJ-3 controller can be used as a two or three point
controller. The output states are shown by LEDs.
The user-friendly EDJ-3 controller is very easy to use.
It has been pre-programmed in the factory so that no
particular previous knowledge of control engineering is
required to be able to solve simple control tasks. After
successfully connecting up and entering the target va-
lues, it is ready for immediate use to control humidifying
or dehumidifying as well as heating and cooling.
Apart from that, the controller also allows you to solve
complex control tasks. By using the keyboard to enter
the parameters, you can set the PID characteristics of
the controller.

The controller inputs are digitally filtered to prevent the in-
put signal from changing too quickly. The filter time can be
set between 0.0 ... 100.0 sec. This means that the control
is no longer affected by interference and transients.
A special feature of the EDJ-3 is the self-optimization (auto
tuning). This means that the controller independently de-
termines the optimal control parameters for a PID control-
ler in the given control environment.
The controller has a "manual mode" in which the output
level can be increased or reduced.
The EDJ-3 offers another useful feature: the offset correc-
tion. This allows the actual values to be adjusted with the
measured values of a reference sensor.
The humidity and temperature controller type EDJ-3 pro-
vides you with a control unit, which can be used to solve
a wide range of problems. The EDJ-3 controller simulta-
neously acquires and controls the humidity and temperatu-
re and is thus suitable for controlling e.g. computer rooms,
air conditioning and maturing chambers, monitoring and
regulating the ambient conditions at print shops, in the tex-
tile industry, the film industry, in hothouses, in warehouses
and many other places.
