The following sections describe maintenance work that is required for optimal and trouble-free operation. Regular maintenance extends the service life and ensures the function of the products over a long period of time.

• During maintenance and servicing, always disconnect the lighting from the mains. 
  If necessary, we recommend cleaning with a soft cloth and mild detergent.
• Permanent moisture as well as limescale and dirt deposits can negatively affect the light quality, performance and service life of the LED bars.
• For closed covers, we recommend using the CleanCover.
• For light sources that cool passively via the ambient air, choose a well-ventilated location. Complete enclosure leads to a build-up of heat and impairs the service life. With closed aquarium covers, the existing openings for cables and hoses are usually sufficient for ventilation; observe the heat development and create additional openings if necessary.
• Compared to fresh water, seawater is an extremely aggressive medium and only very few materials can withstand direct and permanent contact. In order not to shorten the life of the LED bars unnecessarily, appropriate precautions should be taken when using them in seawater. A glass cover on the aquarium is probably the best protection for the lighting. The water cooling system can only be used in marine environments with the TITAN extension!

In addition, the instructions in the operating manual must be observed.

A failure of this kind of a complete LED bar is very unlikely. Usually, such a failure is due to a faulty connection or cable extension. Therefore, please check the connection to the power supply/control unit to ensure that the terminals are correctly and firmly connected.

An improper cable extension/connection can lead to reduced performance, flickering or failure (loose contact).

You should have no or very little algae problems with LED lighting, because the light lacks a UV fraction.
In some rare cases, switching to a different type of light can lead to an unattractive build-up of algae. This can happen in particular if there is a great difference between the light, specifically with regard to quality. I could see this happening here.
If you have a dimmer, you could also temporarily reduce the brightness to ensure a more gradual move to LED light. 

Please understand that it is very difficult, if not impossible, to diagnose problems without being there on the spot.
• Water pollution? Phosphate? Nitrate?
• Perhaps the LED lighting is now stronger than the previous lighting system. 
• You are using (too much) fertiliser because the plants are not consuming as much of it under LED light as they did before
• The period of lighting has been changed 
• The light colour is much different to that used before 
  
If you are operating all the LED bars at full power at the same time, I would suggest initially switching 2 of them off (or even all 3) then increasing the quantity of light each week (as long as algae growth reduces). = darkness treatment.

The heat development of a power supply during continuous operation is normal and unavoidable. This is due to the thermal management, where the power supplies cool themselves through the casing, thereby generating heat. However, the power supplies are equipped with overheating protection. It's crucial that the power supply is properly sized to ensure optimal performance.

The temperature of a LED bar is directly related to its power. Thus, a slight warming of LED bars and the power supply is normal. However, it's crucial to ensure adequate air circulation to dissipate the generated heat. The existing openings in the cover are typically sufficient for this purpose.

If the SunRiser restarts sporadically, does not save settings, activates the LEDs unscheduled or does not load the web interface completely, there may be a defect (write/read error) on the SD card of the SunRiser.

In spite of several function tests by us before shipment, such an error of the MicroSD card can unfortunately not be avoided completely.

Solution 1

Often this problem can be solved with our factory tool. The internal SD card of the Suniser 8 is reformatted, the current firmware is installed and then your configuration is reloaded into the fresh system. If there are problems loading and restoring your configuration - please dispense with this point, repeat the process and select "no". After the restart, you can import your personal backup file in the usual way.

Let's go, open this link and follow the instructions/options.

Solution 2

If the above procedure is unsuccessful, you can alternatively open the SunRiser 8 and remove the MicroSD card.

See a photo at:http://srdemo.ledaquaristik.de/img/sdcard.jpg

Attention: Before you start, disconnect the power supply and disconnect all plugs of the LEDs.

Replacing the microSD card does not affect the guarantee or warranty, we consider this as regular use of the unit.

Now reformat the microSD card (FAT32, no quick formatting) and then save the firmware file "NEW.BEE" on the reformatted card. (You can also use another/new SD card of any size (from 2GB)).

Download the latest SunRiser 8 firmware ("NEW.BEE") at: http://sunriser.ledaquaristik.de/NEW.BEE.

Then insert the card back into the SunRiser 8 and close the unit. The firmware will be installed automatically when the unit is switched on and the SunRiser will restart. After the restart you can read in your personal backup file in the usual way.

If the SunRiser 6 (formerly 4+) does not turn off the light permanently, there is probably a bug in your program, an example:

• 8:00=100%
• 12:00=0%
• 20:00=100%

Result: Only at exactly 12:00 is the lighting at 0%, just one second later the brightness increases again until 100% is reached at 20:00.

• 8:00=100%
• 12:00=0%
• 16:00=0%
• 20:00=100%

Result: From 12:00 to 16:00 the light is at 0%.

Check the programming again. You must also pay attention to the previous and next points.

Possible solutions:

Connect the SunRiser to the router. If necessary, do without repeaters or PowerLAN.
Call up the SunRiser Finderhttp://sunriser.ledaquaristik.de/

Also:

If you use a GBit switch, make sure that it also accepts 10/100Mbit devices.
DHCP should be enabled in your router
Check that the SunRiser is not blocked by the router's MAC address filter.
Eco or energy saving mode of the router: off
If necessary, disconnect other network devices as a test
