1-WAY, 2-WAY & MULTI-WAY CIRCUITS
(CONTINUED)
2-WAY CIRCUITS
2-way lighting circuits have two switches turning the same lights on and off
from 2 different locations (eg. at the top and bottom of the stairs). You must
only replace one of these switches with a dimmerswitch or the lights will
flicker. See Figures 2 and 3 which show typical 2-way circuits. Remove your
old switch and copy the wiring configuration for the dimmer.
The wire(s) fitted in the "common" terminal of the old switch should be fitted
into the "C" terminal of the dimmerswitch. The wires fitted into the other two
terminals of the old switch should be fitted either way round into terminals
"L1" and "L2" of the dimmerswitch.
MULTI-GANG DIMMERSWITCHES
To fit 2 gang (or 3 or 4 gang) dimmerswitches treat each group of terminals
at the back of the unit as a separate dimmerswitch wiring them into the
lighting circuits as described above. If required, one terminal from each
dimmer module may be joined together with a short length of wire to copy
the wiring configuration of the old switch.
PROGRAMMING
OPTIMISING THE PERFORMANCE OF YOUR DIMMERSWITCH
When you first install the dimmer switch it will automatically default to
MODE 1. This mode is the best one for almost all types of LED lighting but
if the lights are flashing in MODE 1 you may be able to improve the
dimming performance by changing the driving mode. [See “Changing the
driving mode” below.] You can always reset to MODE 1. Additionally, the
minimum and maximum brightness setting of the dimmer can be adjusted to
achieve the optimum dimming range for a particular load as follows.
ADJUSTING THE MINIMUM BRIGHTNESS
If your lights are flickering when they are dimmed to a low level you can
increase the minimum brightness setting of the dimmer, which may prevent
this from happening. If the lights are brighter than you would like when the
dimmer is set to minimum, you can try reducing the minimum brightness
setting of the dimmer.
1. Switch on and set the dimmer knob to the MINIMUM position (turn fully
anti-clockwise).
2. Press to turn the lights off and back on again at least 3 times [OFF–ON x
3], leaving approximately one second between presses.
3. The lights will step up and down in brightness, and stay at a low light
level or go off, to show that the dimmer is in CONFIGURATION MODE.
4. Turn the knob fully clockwise. The lights will come on and allow you to
adjust the minimum brightness.
5. Adjust the brightness that you are happy with as the minimum. Leave the
dimmer in this position.
6. After 3 seconds the dimmer will notice that you have stopped adjusting
the minimum. The lights will step up and down in brightness to show that
the dimmer has returned to normal operation.
7.
Continue to use the dimmer as normal.
ADJUSTING THE MAXIMUM BRIGHTNESS
If your lights are flickering when they are set to a high brightness level you
can decrease the maximum brightness setting of the dimmer, which may
prevent this from happening. If the lights are not as bright as you would like
when the dimmer is set to maximum, you can try increasing the maximum
brightness setting of the dimmer.
1.
Switch off and set the dimmer knob to the MAXIMUM position (turn
fully clockwise).
2.
Turn the lights on and back off again. ON – OFF, roughly once per
second.
3.
Set the dimmer knob to the MINIMUM position (turn fully
anticlockwise).
4.
Turn the lights on and back off again. ON – OFF, roughly once per
second.
5.
Set the dimmer knob to the MAXIMUM position (turn fully clockwise).
6.
Turn the lights on.
7.
The lights will step up and down in brightness to show that the dimmer
is in CONFIGURATION MODE, then either stay at a low light level or
go off.
8.
Turn the knob fully anticlockwise. The lights will come on and allow
you to adjust the maximum brightness.
9.
Adjust the brightness that you are happy with as the maximum. Leave
the dimmer in this position.
10. After 3 seconds the dimmer will notice that you have stopped
adjusting the maximum. The lights will step up and down in
brightness to show that the dimmer has returned to normal operation.
11. Continue to use the dimmer as normal, with your new maximum
brightness.
CHANGING THE DRIVING MODE
Unless the lights are flashing it is likely that the best dimming performance
that the lamps can deliver is achieved in MODE 1.
If the lights are flashing then you may be able to improve the performance
of your lamps by manually changing the driving mode to MODE 2, or in a
small number of cases, MODE 3.
1. Switch on and set the dimmer knob to the MAXIMUM position (turn fully
clockwise).
2. Press to turn the lights off and back on again at least 3 times [OFF–ON x
3], leaving approximately one second between presses.

(CONTINUED)
3. The lights will step up and down in brightness to show that the dimmer is
in CONFIGURATION MODE, then stay at a low light level or go off.
4. To select MODE 2, turn the knob fully anti-clockwise or to select MODE
3, first turn the knob fully anti-clockwise then fully clockwise.
5. The lights will FLASH 2 or 3 TIMES to show which mode the dimmer is
in.
6. The dimmer can now be operated normally in the new mode.
To return the dimmer to MODE 1 follow the same procedure. In this case,
both options in step 4 will cause the lights to FLASH ONCE to indicate that
you have successfully returned the dimmer to MODE 1.
[To check which
MODE the dimmer is operating in omit step 4.]
DRIVE FUNCTION
Some LED lights require a large amount of power to come on and so do not
illuminate at low brightness levels. This dimmer is equipped with a DRIVE
function to cater for LED lights that require more power at start-up. To
enable the DRIVE function
1. Switch off and set the dimmer knob to the MINIMUM position (turn fully
anticlockwise).
2. Turn the lights on and back off again. [ON-OFF] roughly once per second.
3. Set the dimmer knob to the MAXIMUM position (turn fully clockwise)
4. Turn the lights on and back off again. [ON-OFF] roughly once per second.
5. Set the dimmer knob to the MINIMUM position (turn fully anticlockwise)
6. Turn the lights on.
7. The lights will step up and down in brightness to show that the dimmer is
in CONFIGURATION MODE, then either stay at a low light level or go off.
8. Turn the knob fully clockwise to switch on the DRIVE function. The lights
will flash once.
9. Continue to use the dimmer as normal with your new maximum
brightness.
To disable the DRIVE function, repeat the above but omit step 8.
RESETTING THE DIMMER
If you change your lights we recommend you reset the dimmer to the
factory default settings.
1. Switch on and set the dimmer knob to the MAXIMUM position.
2. Press to turn the lights off and back on again at least 3 times [OFF–ON x
3], leaving approximately one second between presses.
3. Wait for the dimmer to step the lights up and down. Then press to turn
the lights off and back on again at least 3 more times [OFF–ON x 3],
leaving approximately one second between presses.
4. The dimmer will reset all its settings to factory defaults. The lights will
come on, then fade away to off.
5. Continue to use the dimmer as normal
CHILD LOCK
You can prevent your dimmer from accidentally going into programming
mode by following these instructions. To enable the Child Lock feature
1. Switch off the dimmer and set the dimmer knob to the MAXIMUM
position (turn fully clockwise).
2. Turn the lights on and back off again twice. ON – OFF – ON – OFF,
roughly once per second.
3. Set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
4. Turn the lights on and back off again twice. ON – OFF – ON – OFF,
roughly once per second.
5. Set the dimmer knob to the MAXIMUM position (turn fully clockwise).
6. Turn the lights ON – OFF – ON, roughly once per second.
7. The lights will step up and down in brightness to show that the dimmer
has returned to normal operation.
8. Continue to use the dimmer as normal, with your new Child Lock setting.
9. To disable Child Lock, repeat the whole procedure again.
NB.
It has been noted that some LEDs do not show the programming as
well as others. If you are having difficulty seeing the programming steps,
you can replace one LED lamp with a halogen one for the duration of the
programming in order to see the steps more clearly.
