User Manual (English)

Dear customer,
Thank you very much for
buying a Phocos product.
Please read the instruction
carefully and thoroughly
before using the product.

With your new DCS controller you own a state-of-the art device
which was developed according to the latest available technical
standards. It comes with a number of outstanding features,
like:
Operation of devices (e.g. radios) with different voltages
in solar systems
Selectable output voltages at the output terminals
Electronic overload protection
This manual gives important recommendations for installing,
using and programming as well as remedies in case of problems
with the controller. Read it carefully in your own interest.
Please take note of the safety and usage recommendations
at the end of this manual.
Description of Functions
The controller makes it possible to use electrical devices with
a relatively low supply voltage. By setting the output voltage
with jumpers (the output voltage is always lower than the
input voltage), a wide variety of loads can be connected, for
example devices that normally run on dry cell batteries ( 1.5,
3, 4.5, 6, 9, 12, 13.6 Volt). In addition, the system is protected
against overload.

Mounting and Connecting
General:
When the batteries are not connected (Minus line), the Minus
load output should be connected with Minus IN.
Example:
connecting in
combination with
the CML, CA charge
controllers (Fig. 1.1)

Mounting and Connecting
(keep the right order in mind!)
Set the jumpers in accordance with the intended use of the
controller (see Setting of the controller in the previous chapter).
Mount the controller to the wall.
Connect the connection points of the output terminals with
the device you want to use.
Connect the input terminals of the DCS with the LOAD
clamps of the upstream controller (ensure the correct
polarity!).
Complete the installation by connecting the sensor cable.
Display Functions
Red LED lights up :
Current limitation is active.
Yellow LED lights up:
the controller is ready-tooperate.

General Safety and Usage Recommendations
Safety Features
The controller is not susceptible to overload.
Recommendations for Use
The controller warms up during normal operation, depending
on the connected loads. While in operation, the controller does
not need any particular maintenance or service. Every now
and then, remove dust with a dry tissue.
Intended Use
The DCS controller is intended only for downstream connection
with established 12V photovoltaic systems (no shunt controller!).
With systems in which the Phocos CML, CA or CX controllers
are used, an optimal functioning of the controller is ensured.
If you have any doubts, please contact your dealer or installer.
Safety Recommendations
Batteries store a large amount of energy. Never short circuit
a battery under any circumstances. We recommend
connecting a fuse (slow acting type) directly to the battery.
Batteries can produce flammable gases. Avoid making sparks,
14

using fire or any naked flame under any circumstances.
Make sure that the battery room is sufficiently ventilated.
Avoid touching or short circuiting wires or terminals. Be
aware that the voltages on specific terminals or wires can
be up to double the battery voltage. Use isolated tools,
stand on dry ground and keep your hands dry.
Keep children away from the batteries and the charge
controller.
Please observe the safety recommendations of the battery
manufacturer. If in doubt, consult your dealer or installer.
Reverse polarity at the connector clamps should be avoided
under all circumstances, as this can damage the device
and/or the battery.
This device has been developed and manufactured with
care. As with any technical device, it has a limited life
span. If batteries should be charged with the device, you
should check regularly, if the voltage of the batteries falls
within the permissible range. If no, disconnect the controller
and other connected devices from the battery and contact
your dealer or installer.
Liability Exclusion
The manufacturer shall not be liable for damages, especially on
15

the battery, caused by use other than as intended or as
mentioned in this manual or according to the recommendations
of the battery manufacturer. The manufacturer shall not be
liable if there has been service or repair carried out by any
unauthorized person, unusual use, wrong installation, or bad
system design.
