Connecting the lighting ( Also see the other connectivity options on pages 19 & 20 )
The controller communicates with the Dimlux ballasts or the light xtures by means of a signal cable, which should be
connected between the controller and the various ballasts and light xtures. Interlink cables are supplied with both the
Maxi-controller and the ballasts/ light xtures. Separate Interlink cables can be ordered in different lengths. Ask your
dealer for more information.
Interlink cables
There are 2 ports for Interlink cables, namely OUT 1 and OUT 2, on the side of the controller. Up to 80 ballasts or light
xtures may be connected to each port, which means that in total, 160 ballasts or light xtures can be connected as
long as the original Dimlux Interlink cables are used.
Interlink cables (UTP)
There are two ports on the ballasts or light xtures, on which the Interlink cables are connected. The port on the Maxi
Controller (out 1 and/ or out 2) is connected to port A of the ballast or light xture. Port B is now connected to port A
of the ballast or light xture via an Interlink cable. The sequence is therefore controller-out> port A, then from B to A /
B to A / B to A etc. A is therefore the input signal and B is the output signal.
At high temperature safeguard, ballasts or light xtures will now switch off alternately. Thus, it is not (no longer) required
to connect the signal wire alternately. The electronics in the ballasts or light xtures regulate this independently.
There is a green plug with three terminals +1, +2 and - (minus), under the 2 OUT ports. This connection can be used to
control older types of ballasts or light xtures without Interlink.
The ABP jack enables the connection of a 2nd Maxi Controller. The two controllers then work together on 1 clock /
timer in the master / slave conguration. Master-slave copy or invert should be selected in the 2nd controller, using
the mode button. The 1st controller is set to the normal function (on / off / timer / countdown) using the mode button.
double-core cables
Older models ballasts or light xtures without Interlink connections can also be controlled with the EVO 1.2. The green
connector beneath the OUT ports can be used for this. Here, up to 40 ballasts or light xtures can be connected per
port. (80 in total)
double-core cable to following ballast >< to following ballast
The controller is connected to the ballasts or light xtures using a double-core cable. On the controller, you can choose
for port +1 and - (minus), for instance. This is then connected to + and - on the ballast or light xture. If there is more
than one ballast or light xture, the double-core cable can be looped in series from the rst ballast/light xture to the
next one. Always + to + and - to -.
When installing multiple ballasts / light xtures, this should always be distributed over port +1 and port +2. In case of
a high temperature safeguard, port +2 switches off.
Connecting the CO2
The dual-beam CO2 sensor can simply be plugged into a wall socket.
The long cable including the plug is inserted into the port with the CO2
indication.
Now you can connect the CO2 generator or pressure-reducing valve to
the CO2 sensor.
Connecting the auxbox
The fan/ auxbox is easily connected to an existing wall socket. The 5m
communication cable is connected to the aux port via the plug. Now the
apparatus for controlling the box must be inserted into the correct port.
Connecting the VPD
To be able to determine the VPD value, the temperature sensor,
RH% sensor and PT camera should be connected to the controller.
Both the temperature sensor and the RH% sensor should be covered
against the incidence of light. A cardboard cover is sufcient.
The PT camera should be mounted in such a way that it “illuminates” the crop
under an angle of approx. 45º without measuring walls, reectors or other
parts of the room as well. A circle with a diameter of 50 cm is measured if the
distance to the crop is 50 cm. The circle is 80 cm if the distance is 80 cm.
