3 short red flashes for mode 3, permanently repeated
Mode 3 = optimized mode for LEDs
, power 8 – up to 200VA, to be used with:
–
230V dimmable electronic converters or Leds
Mode 3 differs from Mode 1 by a lower minimum level and a different dimming's curve
4 short red flashes for mode 4, permanently repeated
Mode 4 = antiflicker-optimized mode for LEDs
, power 8 – up to 200VA, to be used with:
–
230V dimmable "Filament"-type LEDs
Mode 4 may also be tested in case of flickering with other types of LEDs
The red indicator displays for 1 minute after every action on the dimmer. It is permanently on in case of an error.
When switching the mode by rotating the selector (clockwisely or counterclockwisely), the DimMax 420SL will fully reset. It means:
- the dimmer output goes smoothly OFF, the load is shut off
- the red indicator goes ON for 0.5 s to confirm a mode change
- and then, the new mode code is displayed
Tip: Switching modes is an easy way to fully reset (including error conditions) a unit without disconnecting it from the 230V.
As soon as the mode code is displayed, the DimMax 380SLX is ready to be operated from the pushbutton.
Important note about maximum LED power on the DimMax 380SLX
Market offers high quality... but also poor quality dimmable LEDs. Their design is regularly changing, even for similar models from
the same manufacturer. Some, despite being claimed dimmable, only show a limited dimming range, and/or can cause huge
transient currents.
Due to the current absence of international technical standards, it is impossible to guarantee that any market model will correctly
behave and allow to reach a maximum of 200VA. If any doubt remains,

BEFORE buying the LEDs
Error conditions and red indicator displays
:
The DimMax operation is permanently monitored by its processor. If an error occurs, the processor triggers a protective action, and
the red indicator stops displaying the operation mode, to show the error code.
ON/OFF short flashes, permanently repeated, for
overcurrent
means that a transient current higher than the allowed limit has occured.
The dimmer goes OFF immediately and the pushbutton is disabled for 1 minute;
when the red indicator displays the mode code again, the unit can be reactivated with the pushbutton.
ON/OFF long flashes, permanently repeated, for
overtemperature
means that the internal temperature exceeds the allowed limit.
The dimmer smoothly goes OFF and the pushbutton is disabled until the internal temperature drops below the half; when
the
red indicator
displays the mode code again, the unit will automatically smoothly retrieve its last dimming level.
Hardware protections
:
For more safety, the DimMax 380SLX is also equipped with 2 hardware protections, independent of the processor:
•
an auto-resettable thermostatic switch on 230V input
•
a (not resettable) wired fuse in case of exceptional failures
The
red indicator
goes OFF when one of those protections is triggered.
Pushbutton operation
:
LONG PUSH (> 0.4s) on the button: the unit starts dimming (if not already started) and slowly dims up/down between Min
(adjustable) and Max level (100%); the last output level is memorized when the button is released.
SHORT PUSH (<0.4s) on the button: the unit starts or stops dimming with a soft transition.
When stopping, the unit will remember its last output level (Memo level), and retrieve it on the next start (ex factory default setting).
User may decide NOT to use the Memo level, and replace it by the Max level. To set this feature OFF or ON, do a LONG PUSH
immediately followed by 4 SHORT PUSHES. Dimmer will softly stop to confirm the change.
WARNING : even when OFF, an electronic dimmer NEVER ensures GALVANIC isolation of the connected load.
DOUBLE PUSH. This option is set OFF ex factory, but the user can decide to activate it with a LONG PUSH immediately followed by
6 SHORT PUSHES. With this option, 2 consecutive short pushes allow the dimmer to immediately reach the Max level, and the next
2 consecutive short pushes (if there is no other button action inbetween) will bring the dimmer back to its previous level.
DIMMING DIRECTION AUTOMATIC INVERSION. If the min or max level is reached during a LONG PUSH, the dimming direction
inverts after a short delay. This can be cancelled/restored with a LONG PUSH followed by 8 SHORT PULSES.
Memo level, Memo ON/OFF and DoublePush ON/OFF statuses are permanently remembered EVEN if the DimMax 380SLX is
disconnected from the 230V. At first use or after a reset, Memo level is 50%.
Minimum start level selector
:
The minimum start level can be adjusted from 3% to 30% with
the minimum start level selector.
As soon as the selector is moved, the unit will forget its current dim level (if
already ON) or will go ON (if it was OFF) in order to show the minimum level
being adjusted on the light bulbs. Stop increasing it when the light bulbs
remain stable.
