Sera LED Digital Dimmer Handbuch Seite 8

Location
The sera LED Digital Dimmer should be installed
in an easily accessible and dry place. Use the hold-
er for installing the dimmer into the cabinet or where
you prefer. The holder (1.2) can be attached with
4 screws (1.3).
Operation
ON/OFF
Press "MINUTE" to switch the light ON/OFF.
Adjusting brightness
You can adjust brightness individually: Adjust the
maximum brightness by pressing the keys "+" and
"-". The automatic dimming process also ends at the
brightness adjusted here. You can adjust different
brightness levels by pressing "+" for a long time, and
you can also reach other positions stored with 100%
brightness.
These depend on the system. In case you stored one
of these positions and later on wish to reduce the
brightness, you may need to press the "-" key for a
longer time to reduce the brightness in visible steps.
Attention! Before using at the aquarium or in case of
apparently insufficient brightness inside the aquari-
um in spite of sufficient LED equipment, first check
whether the maximum brightness of the dimmer is
adjusted correctly, and correct if required.
Adjusting the actual time
Press the "SET" key for approximately 3 seconds.
The display will then start to flicker. Then press the
"HOUR" key (for adjusting the hours) and "MINUTE"
(for adjusting the minutes) to set the actual time.
Pressing these keys will increase the displayed dig-
it by "1" every time. If keys are held down, the num-
bers in the display start to run upwards quickly.
Adjusting the sunrise time
After adjusting the actual time, press the "SET" key.
Now "ON" is displayed for the sunrise. The display
changes to input mode immediately afterwards. The
beginning of the sunrise can be adjusted by the
"HOUR" and "MINUTE" keys as desired (see adjust-
ing the actual time).
Adjusting the sunset time
Press the "SET" key again. Now "OFF" is displayed
for setting the sunset time. The display changes to
input mode immediately afterwards. The beginning
of the sunset can be adjusted by the "HOUR" and
"MINUTE" keys as desired (see adjusting the actual
time).
Adjusting the switch mode
You can adjust the switch mode (F1 – F4) by press-
ing the "SET" key again. You can choose between
the following programs:
Program Function
F1 Sunrise/sunset
with clear sky
F2 On/Off
F3 like F1, plus
Cumulus cloud
simulation
F4 like F1, plus
Cirrus cloud
simulation
Pressing the "HOUR" key repeatedly switches the
programs in the order F1, F2, F3, F4, F1, F2 ... etc.
During the programs F3 and F4 the light is reduced
to 10% or 30% of the adjusted light brightness, re-
spectively. This takes place for slightly over a minute
every 20 or 15 minutes, respectively. However, these
cloud scenarios only begin one hour after sunrise.
Confirm the settings with pressing "SET". This will
put the dimmer back in operation mode.
Reset function
Press the key "MINUTE/ON/OFF/RESET" for 3 sec-
onds. This resets the unit to default settings.
Demo Mode
Press the "HOUR/F1 – F4/DEMO" key for approx-
imately 3 seconds. Now sunrise and sunset will be
performed within 75 seconds with one cloud simu-
lation. After finishing, the dimmer will return to op-
eration mode.
Power supply
Should the sera LED Digital Dimmer be disconnect-
ed from power supply for minutes or longer, the
stored data will be lost and need to be entered again.
Advice
It is impossible to influence the brightness by any
manual adjustments while dimming processes are
running. Manual dimming procedure adjustments can
be done only after finishing.
Functional effects
Depending on the combination of LED tubes con-
nected to the sera LED Digital Dimmer, there are
different illumination scenarios. For instance, the
"sunrise" tube will start first to simulate the sunrise.
Cleaning
The surfaces can be cleaned carefully with a moist
cloth and with a neutral detergent. Make sure no
detergent gets into the aquarium. Please unplug the
power cord before cleaning.
