1 General Information
1.1 MLD technology
DEGER’s patented MLD Control allows for accurate, quick and power-saving operation in orienting the
dual-axis DEGER systems to the position that has the most energy. This grants the MLD Control the
capability to obtain the greatest yield possible for a dual-axis mechanism. Two MLD sensors determine
which place in the sky has the greatest yield and move the module surfaces into this position. With the
DEGER system mechanism, the control can align the module surfaces to the sun accurately at all times
throughout the entire year. Not only does the control take into account the sun’s irradiation, it also accounts
for reflected light, for example, from snow, water or light-coloured rock, and for the diffuse irradiation
penetrating the clouds –and it does this individually for each system. In practice, this means that if clouds
move in from the west in the afternoon on an otherwise sunny day, the module surface will turn back to
face east based on irradiation. When there is full cloud coverage, the module surfaces will move either into
the horizontal position or into a position with higher irradiation so that the best yields can be obtained in any
weather situation. The control is designed to work in the most efficient way possible, and it moves only for
the purpose of directly increasing the yield.
Sunshine: The DEGER system directly faces the sun all day.
Varying light conditions: Because of different levels of cloudiness, the light conditions in solar parks vary for each DEGER
system. The individual control makes sure every DEGER system is optimally oriented to the brightest source of irradiation.
This guarantees the highest energy yield possible.
Snow, sand, gravel etc.

diffuse light
Reflecting surface: The DEGER system
uses direct solar irradiation as well as
energy from reflected light.
Partly clouded: In addition to the direct
solar irradiation, diffused light is also
used to maximize the effects.
Overcast sky: The DEGER
systemcatches all the diffused light by
moving to a horizontal position.

1.2 Introduction
These assembly instructions were created for the DEGER system. They are a component of the product and
must be saved for the entire lifespan of the DEGER system. The assembly instructions must be submitted
with the DEGER system should it be transferred to another party.
1.3 Fundamental safety notes
Read these assembly instructions in their entirety before starting assembly work and keep them available
at all times during the assembly process.
Only qualified personnel may perform assembly work.
Keep all objects out of the DEGER system’s range of pivoting motion throughout its full range of motion.
Take proper actions to protect the installed DEGER system in its full range of motion from unauthorised
access, such as enclosing it with a fence. Near the entry area to the DEGER system there must be a
warning sign stating that it is prohibited to remain within the range of pivoting motion.
Lightning protection and grounding must be installed in all photovoltaic systems according to country-
specific guidelines as stipulated in DIN VDE 0185 and 0100.
Do not operate the DEGER system if the wind monitor is not functioning. Always keep the module surface
in the SAFE position (table position) until the wind monitor has been tested for function.

- Drilling holes in any housing, e.g. Central Control Box (CCB), Energy converter 6 (EC-6) and Evaluation
unit wind monitor (Use existing free holes for mounting the housings)
- Malfunction of the DEGER system caused by the effect of connected or adjacent devices beyond the
permissible limiting values
- Disaster situations and force majeure
- Installation of non-genuine DEGER replacement parts
- Unauthorized modifications to any parts
- Damages to any third party components (e.g. inverter or modules)

2.2 EC-6: Function
Priorities in operation: 1. Only one motor can be active (either AZ or EL), never both at the same time.
2. MLD sensors: AZ has priority over EL.
3. External inputs have priority over MLD sensors.
4. External EL input has priority over external AZ.
Reverse polarity function:
This function is used to make sure the module surface is within the transmission range of the MLD sensors in
any weather situation.
The reverse polarity function becomes activated when the same signal has been present at inputs 13-14 of
EC-6 for longer than 7 minutes. The reverse polarity function remains active for 6 minutes. Signals from the
MLD sensors are ignored during this time. The external inputs, joystick, broken wire detection and wind
monitor have priority. Jumpers can be used to deactivate the reverse polarity function.
Reverse direction function:
This function ensures the module surfaces are facing east the next morning to receive the first rays of
sunlight.
The AZ motor will switch on for 12 minutes once the EC-6 has not registered a signal at inputs 11-12 and 13-
14 for more than 4 hours. In the northern hemisphere, the system must rotate to the south; in the southern
hemisphere, it must rotate to the north. Either jumper J3 or J4 must be connected for this function.
The external inputs, joystick, broken wire detection, MLD sensors and wind monitor have priority. Jumpers
can be used to deactivate the reverse direction function.
SAFE POS (broken wire detection) function:
This function is used to compensate for any possible malfunctions (e.g., cable interruptions).
Continuous voltage of DC 24 V must be present at EC-6 inputs 20-21 for the control to function normally.
The EL motor output will be controlled continuously if the voltage signal is interrupted. The module surface
will move into the SAFE POS (table position). The SAFE POS output has top priority.
Jumpers can be used to deactivate the SAFE POS function.
2.3 EC-6: Default setting
Delivery for southern hemisphere: Delivery for northern hemisphere:
Jumpers J1, J2 and J3 are connected. Jumpers J1, J2 and J4 are connected.

Jumper J2 must be connected to J7 for broken wire detection to be activated.

2.4 EC-6: Changing configuration
DANGER!
Only trained and qualified personnel may make changes to the configuration by moving the
jumpers. The configuration may be changed by moving the jumpers only when no voltage is
present.
ATTENTION!
Some countries require there to be a broken wire detection function. We strongly recommend
using the broken wire detection function in all installed systems and checking it regularly for
proper function.
ATTENTION!
Changing the default settings will void any warranty claims.
