Dimmax 420SLR – User manual
Foreword
•
The Dimmax universal dimmer can dim your LED lightings, classical light
bulbs and halogens (230V/12V via transformer).
•
The Dimmax 420SLR is designed to be mounted on a DIN rail.
•
For an optimal functioning, only connect a single type of lamp.
•
A connected pushbutton is required for the functioning of the dimmer.
•
The dimmer must have a proper power supply (phase, neutral).
•
The dimmer remembers its last dimming position (ex-factory setting: 50%).
•
The power a Dimmax 420SLR is of 0 to 200W for LEDs and of 0 to 420W
for other lamps; 30 lamps max.
Wiring and configuration of the dimmer
In order to get a good dimming, these steps must be carefully followed:
1. Plug the dimmer according to the
hereby enclosed diagram (cut off the
230V with the circuit breaker first)
2.
Plug the lamp and make sure it is
properly dimming (ex-factory
configuration of the dimmer is set to
mode 1).
•
The lamp is correctly dimming?
(progressively and to a minimal level):
→
go to step 3.
•
The lamp isn’t correctly dimming?
(improperly or not at all
): →
try with
another mode.
•
The lamp isn’t correctly dimming
in any mode?
(improperly or not at
all
): →
Read thoroughly the user
manual as well as the possible error
codes detailed in the technical
documentation available on the
website.
3. Now set the minimal dimming level
with the right selector (minimal
threshold).
In case you have a question, see the
detailed version at
or contact
your supplier.

Dimmer 420SLR
230V
0-420W (LED 0-200W)
46 x 46 x 18
•
Nominal conditions: 230V AC +/- 15%, 50 Hz, Ambient temperature: -
10°C to 40°C.
•
The Dimmax 420BLE is designed for lightings. Other loads (such as engines)
are forbidden.

•
Maximum tightening torque: 0,4 N.m (use a dynamometric screwdriver).
•
2 self-resettable protections: against overcurrent and temporary overheating
•
2 additional physical protections: a thermostatic 230V power cut-off switch,
self-resettable, and a fuse (non-replaceable)
•
IP20 protection degree
Safety and environment
•
Without halogen, RoHS.
•
Storage conditions: Temperature: -25°C / +70°C, Relative humidity: <
75%.
EN_20180419
•
For a safe installation, the device can only be mounted by a qualified
electrician.
•
The device must not be opened in any case (cancels warranty).
•
The device can only be installed inside, in a dry place, compatible with
IP20 devices.
•
During the mounting and unmounting of the device, cut off the 230V
circuit-breaker.
•
The screws of the connectors of the device are unscrewed at delivery
and must be properly screwed before use.
•
After installation, the screws of the connector must be protected so that
could not be accessible for the final user.
Operation mode settings
After reconnexion of the 230V, the 420BLE Dimmax turns on
while its
red
indicator
turns on for 0.5 second.
Smoothly turn (clockwisely) the
operation mode setting
from its stop (fully
left). The first quarter = mode 1, second quarter = mode 2, etc up to mode
4. Mode selection is confirmed with a visual code of the
red indicator:
Mode 1
(1 short red flash, endlessly repeated)
= trailing edge dimming
, to
be used with:
•
230V classical light bulbs and halogens (BEST at cold startup), power
0 – 420W.
•
230V dimmable electronic converters or LEDs designed for trailing
edge, power 0 – 200VA.
Mode 2
(2 short red flashes, endlessly repeated)
= leading edge dimming
,
(also called "triac mode"), to be used with:
•
Disc-wound transformers for 12V halogens (the Dimmax 420BLE
automatically detects them and forces mode 2), power 0 – 380VA.
Caution: the load for this type of transformer must be of at least 80% of
the nominal power of the transformer.
•
Electronical converters or dimmable leading edge compatible LEDs,
power up to 200VA.
Mode 3
(3 short red flashes, endlessly repeated)
= power-optimized mode
for LEDs,
power up to 200VA, to be used with:
•
Electronical converters or 230V dimmable LEDs.
LMode 3 was designed to control more LEDs (or converters) with usually
less losses and reduced peak currents. However, some LEDs are better
dimmed with other modes. Do no hesitate to try.
Mode 4
(4 short red flashes, endlessly repeated)
= anti-flickering
optimized mode for LEDs
(can particularly fit 230V dimmable « filament »
type LEDs); this mode leads to a significantly reduced power compared to
other modes.
When a mode limit is crossed by turning the selector (one way or the other),
the Dimmax 420SLR is reinitialized. This means:
•
The dimmer output is slowly TURNED OFF, the load is cut-off;
•
The
red indicator
turns on for 0.5s to confirm the mode switch;
•
And then, the
red indicator
will display the code of the new mode.
Tip: Cross a mode limit is an easy way to reset (including error conditions)
without cutting-off the 230V.
As soon as a mode is displayed, the Dimmax 420SLR is ready to work
under the control of the pushbutton.
Pushbutton control
For a LONG PUSH (>0,4s) on the button: the dimmer turns on (if it was
OFF) and the dimming level slowly increases/decreases between Min
(settable) and Max (100 % = total conduction) level; the last level is
maintained by releasing the button.
For a SHORT PUSH (<0,4s) on the button: the dimmer turns on or off with a
smooth transition.
