2. DESCRIPTION
Controlling the intensity (dimming) of all dimmable loads except for fluo-
rescent lamps.
Resistive loads: incandescent lamps, 230V halogen lamps...
Inductive loads: ferromagnetic transformers
Capacitive loads: electronic transformers...
3. OPERATION AND USE
This dimmer (05-707) operates with power transistors instead of triacs. This
allows both phase control and reverse phase control dimming.
In phase control, the dimmer is switched off at the zero crossing and
switched on beforehand. This switch technique is recommended for
inductive loads (ferromagnetic transformers). In reverse phase control, the
dimmer is switched on at the zero crossing and switched off afterwards.
This switch technique is recommended for:
- capacitive loads (dimmable, electronic transformers 230V~);
- resistive loads;
- mixed loads (above-men inductive loads) connected to the
same dimmer.
Because the interference suppression is full-electronic and no chokes are
used, these dimmers are completely silent and up to 30% lighter than
classic dimmers. The technology used enables to electronically protect the
dimmer against short-circuit, overcurrent and overvoltage.
This dimmer is remote controlled either via an analog signal or via potentialfree
N.O. contacts (e.g. 07-000). The control is galvanically separated from the
mains. Both the analog and the push button wiring is carried out under very
low voltage. A lamp that is connected via dimmers cannot be dimmed to
the max. light intensity. The light intensity will always be less in comparison
with an identical lamp that is directly connected to the mains.
3.1 Analog control
(e.g. via Nikobus 05-007-02)
This dimmer (05-707) can be remote controlled with any device that complies
to the international 0-10V (voltage control) and the 1-10V (current control)
standard. Operation is analogue (0V = off, 10V = max. light intensity). Analog
control and signal cables are galvanically separated from the mains via the
dimmer. The wiring is carried out in ELV (extra low voltage).
3.2 Push button control
Any potentialfree N.O. contact can control the dimmer. Press briefly for
on/off, press long to increase/decrease (fig. 1 & 2). The push buttons are
galvanically separated from the mains via the dimmer. The wiring is carried
out in ELV (extra low voltage).
3.3 Warning
- This devices are not suitable for controlling motors, unless the specific
safety requirements are guaranteed by external systems (in this case,
automatic restart after power cut is not allowed).
- This device is exclusively suitable for DIN-rail mounting and must be
mounted in a closed distribution board.
- This device can only be connected to the power supply after installation
of the necessary covers in the distribution board.

Dimming mixed loads and activating the dimmer
A mixed load consists of wound transformers (inductive loads) and electronic
transformers (capacitive loads) that are connected to the same dimmer.
Lamps without control gear (e.g. incandescent lamps) are resistive and
form a neutral load. If the load is not mixed, see 4.1 and 4.2.
Attention:
for dimming mixed loads, the dimmer has to be set in reverse
phase control. Mixed loads cannot be dimmed in phase control. Induction
must be compensated in case the overvoltage protection is activated in
reverse phase control (red LED no. 4 lights). Inductions of wound transformers
are compensated in the same way as ballasts of fluorescent lamps: place
a X-2 class capacitor between phase and neutral on the primary side of
the transformer. Value ± 1micro Farad per 50VA.
Follow the procedure described below if you are in doubt as to the type
of load.
Set the dimmer in reverse phase control (dimming electronic transformers
and/or resistive loads) by switching DIP switch 1 to OFF (4.2). If no red
LEDs light, this means that the load is predominantly capacitive and that
the setting is correct.
If one or more red LEDs light and/or the dimmer does not work (dimmer
in protective mode), this means that the load is predominantly inductive.
In this case, switch the DIP switch 1 to ON (= phase control for inductive
loads, see 4.1). Press the reset key or set the analog signal to 0V to restart
the dimmer. Resistive loads are neutral and have to be dimmed in reverse
phase control.
4.1 Phase control:
switch DIP switch 1 to ON
Only inductive loads (ferromagnetic transformers) can be dimmed in this
mode. All other loads, incl. resistive loads, have to be dimmed in reverse
phase control (4.2). When this mode is selected, yellow LED 1 lights as a
check (5.1).
4.2 Reverse phase control:
switch DIP switch 1 to OFF
Only resistive and capacitive loads can be dimmed in this mode. These
loads can be mixed. Never connect only inductive loads in this mode (4.1).
Also use this mode for mixed loads (ind capacitive).
Attention: electronic transformers of over 105VA are not suitable for dim-
ming. These transformers can produce unstable light (blinking). If the load
is purely capacitive, the dimmer must be at least loaded by:
- 2 or more electronic transformers;
- or 1 electronic trans 1 electronic auxiliary load (09-016-10).
Switch the dimmer to this mode if you are in doubt as to the type of
load.
4.3 Push button control:
switch DIP switch 2 to ON
This setting enables control via N.O. contacts. Press briefly for on/off. Press
long to increase/decrease. When pressing long, the dim direction is reversed
after each interruption (increase -> stop -> decrease -> stop -> increase
-> …). The last level can be stored in a memory (4.9).
4.4 Analog controls:
switch DIP switch 2 to OFF
This setting enables to control the dimmer via analog control signals (4.8).
4.5 Automatic selection of the type of control signal (0-10 or 1-
10V):
switch DIP switch 4 to ON
In this mode, the dimmer will automatically discern the type of control
signal and choose the setting (as opposed to the manual setting described
in 4.6). This setting is only made when the power supply is switched on.
Conditions for the use of automatic selection:
Only use the manual setting if several dimmers are connected to the same
control output. The use of different types of dimmers can affect the detec-
tion. If 05-707 dimmers are distributed over different fuses, all fuses must
be switched on within 10s. to avoid detection problems.
4.6 Manually setting the control signal: switch DIP switch 4 to
OFF
In this mode, the type of control signal (0-10 or 1-10V) is manually selected
by the setting of DIP switch 3 (4.7 and 4.8).
4.7 Manually setting the control signal to 0-10V: switch DIP switch
3 to ON
To use this function:
- DIP switch 4 first has to be switched to OFF (manually setting the control
signal: see 4.6)
- DIP switch 2 has to be switched to OFF (analog control).
When this mode is selected, yellow LED 2 lights as a check. In this posi-
tion, the dimmer will accept a voltage control signal from 0 to 10V in
accordance with the IEC standard 61131-2. From 0 to 10V it is possible
to adjust the light intensity from 0.1% to max. The dimmer is switched off
at 1V (functions as a solid-state relay).
4.8 Manually setting the control signal to 1-10V:
switch DIP switch
3 to OFF
To use this function:
- DIP switch 4 first has to be switched to OFF (manually setting the control
signal: see 4.6).
- DIP switch 2 has to be switched to OFF (analog control).
In this position, the dimmer operates via a current control signal from 1 to
10V in accordance with the EN60929 standard (see also 4.7). From 0 to
1V, there is no adjustment of the light intensity. From 1 to 10V it is possible
to adjust the light intensity from 0.1% to max. The dimmer is switched off
at 1V (functions as a solid-state relay).
4.9 Push button operation with memory:
switch DIP switch 4 to ON
If the dimmer is controlled via a push button (4.3), you can choose operation
with memory (DIP switch 4 to ON) or without memory (DIP switch 4 to OFF).
Without memory, the dimmer switches on at max. light intensity. With memory,
the dimmer switches on at the last set value. After the power voltage has been
switched on, the dimmer switches on at 20%.
5. OPERATIONAL AND ERROR CONTROL BY MEANS OF LEDS
This dimmer is provided with a visual control function by means of 4 LEDs
which remain visible on the front of the dimmer after installation.
From left to right (fig.4):
5.1 Indication of operation in phase control:
LED 1 lights (yellow)
Inductive load symbol above LED 1. This LED lights when DIP switch 1
is switched to ON.
5.2 Indication of control signal selection in voltage control:
LED 2 lights (yellow)
Regulated supply symbol above LED 2. This LED lights when DIP switch 3
is switched to ON and DIP switches 4 and 2 are switched to OFF.
5.3.1 Overcurrent:
LED 3 lights (red)
Symbol I above LED 3 and ‘overcurrent’ indication to the left of LED 3.
This protection is activated if:
- the dimmer is overloaded;
- there is a short-circuit in the load circuit.
If the red LED lights, the protection is activated. This can happen in case
of switch-on surges or short-circuits.
In case of a short-circuit, the dimmer is automatically switched off.
Note: all protection systems are active when the mains supply is switched
on. For several seconds, they are deactivated one after the other. The dim-
mer does not react to the remote control signal for as long as this control
has not been completed successfully.
Once the error has been rectified, the dimmer can be switched back
on as follows:
- press the reset key;
- adjust the control signal to min. level (0 or 1V resp.).
Attention:
this protection is not intended for people. An external automatic
protection (automatic fuse) must always be provided.
5.3.2 First thermal protection:
LED 3 blinks (red)
If the temperature of the cooling surface exceeds 105°C, this protection
is activated and:
- the third LED blinks (red);
- the power of the dimmer is restricted to 20% (the light intensity can be
adjusted to max. 20%).
As soon as the temperature has dropped, the LED goes out and the dimmer
can be operated normally again.
5.4 Overvoltage protection:
LED 4 lights (red)
Overvoltage protection (symbol U above LED 4 and ‘overvoltage’ indication
to the left of LED 4).
This protection is activated if an overvoltage (greater than 480V for more
than 100µs.) occurs. An overvoltage can have several causes:
- a temporary or otherwise fault on the 230V mains;
- magnetic transformer with a too high induction caused by e.g. insufficient
load (min. load of magnetic transformers 75%);
- magnetic transformer with change in the load (defective lamps not
replaced in time);
- the dimmer is not set to the correct mode, e.g. dimming inductive loads
in reverse phase control instead of phase control (see 3).
If the protection is activated, this indicates an abnormal situation. If the
dimmer stays in protection mode, the error must be found and rectified.
Once the error has been rectified, the dimmer can be switched back
on as follows:
- press the reset key;
- or adjust the control signal to min. level (0 or 1V resp.).
5.5 Indication of direct current or thermal protection:
LEDs 3 + 4 light
Indication of direct current or thermal protection.
5.5.1 Direct-current protection
If an asymmetry of over 1.5V is measured, the dimmer will enter protec-
tion mode. This is particularly important for dimming inductive loads. If
the dimmer mistakenly dims inductive loads in reverse phase control, this
protection will be activated. An too high asymmetry causes humming,
heating and ultimately burning of transformers and lamps.
5.5.2 Second thermal protection
The second thermal protection is self-restoring. In case of overheating, the
device is switched off from 115°C on the cooling surface. For as long as
the thermal protection is activated, the dimmer will not react to the control
signal. If the temperature has dropped, the dimmer switches back on.

6.1 top from left to right
L: 230V phase (power supply)
N: 230V neuter (power supply)
N: 230V neuter (load) interconnected
: regulated phase (load)
The neuter of the load must be connected to the dimmer. If the neuter
is directly connected to the mains, the operation of the dimmer is not
guaranteed.
Attention: before switching on, check whether all connections are secure.
During maintenance on the installation, the pressure on the terminals
must be checked.
6.2 control connections: analog signal
Control with analog signal (bottom):
'-' terminal: mass of the control signal (0V)
'+' terminal: control signal: analog control from 0 or 1 to 10V
Attention:
the same terminals are used both for 0-10V voltage control
and 1-10V current control and push button control. Take into account
the polarity. In case several dimmers are connected to one and the same
control output, never confuse the '-' and '+'.
The control input is galvanically separated. The insulation within the dimmer
guarantees control at extra low voltage.
The 1-10V current control is described in the European standard EN60929.
This control technique is mainly used for controlling electronic control gear
(ECG) by means of so-called electronic potentiometers e.g. 09-011. The
intensity of the current passing through the control circuit determines the
light intensity. These so-called “current sink” control signals fundamentally
differ from the 0-10V control signals, known as “source” signals. The
0-10V voltage or “source” signals are typically used in professional ap-
plications such as: PLCs, Silicon Controls control systems or the Nikobus
dim controller 05-007-02.
6.3 Control connections: push button control
Control with N.O. contacts (bottom):
'-' terminal: common for all contacts
'+' terminal: signal
The push buttons can under no circumstances be connected to the mains.
