05-728
Read the complete manual before attempting installation and
activating the system.
1. dESCRIPTION
Regulating the intensity ('dimming') of all dimmable resistive and inductive
loads with the exception of fluorescent lights and capacitive loads (elec-
tronic transformers...).
Resistive loads: incandescent lamps, 230V halogen lamps, ...
Inductive loads: ferromagnetic (wound) transformers
Resistive and inductive loads can be mixed.
2. OPERATION ANd USE
The dimmer 05-728 operates with triacs (phase control). The dimmer is
remotely operated by one or more N.O.-contacts (170-0000X). A short
press on the key switches the light on or off (operates as a switch). A longer
press on the key operates the dimming of the light. The duration of a cycle
is ±4s. for the regulation of incandescent lamps (min. - max. - stop). A
new press reverses the dim direction. The time between two contacts
must at least be 500ms. (fig.1 and 2). The push buttons are connected to
the dimmer through an internal opto-coupler to avoid interference. Lamps
connected via dimmers can't be dimmed to the max. light intensity. The
light intensity will always be less in comparison with an identical lamp
which is connected directly to the mains. The dimmer is provided with a
system that avoids blinking in case of a sudden dips in the mains frequency.
'Frequency dips' up to 3Hz are absorbed by reducing the light intensity.
The dimmer can be dimmed to max. at the next operation. Depending on
the mains frequency, it may take up to 20s. (40Hz) before the dimmer can
be operated after switching on the mains.
2.1. Local operation
The dimmer is provided with a push button on the front panel. This button
has the same control function as the remote ones and can be used for
local testing or setting the memory function (see 2.3.).
2.2. Remote control
Remote control operation with N.O.-contacts (non-lit). Press briefly to switch
on/off. Press long to increase/decrease. When pressing long, the dimming
direction is reversed after each interruption (dim up -> stop -> dim down
-> stop -> dim up -> ...). Once the max. level of light intensity is reached,
this level will stay unchanged, even if the push button is still pressed. The
last level can be stored in a memory. (see 2.3.). Up to 30 N.O.-contacts
(170-0000X) can be connected in parallel (max. distance 50m). Different
wiring configurations are possible (see diagrams).
2.3. Memory function
The dimmer can both be used with or without memory. Without memory
function, the dimmer switches on at max. light intensity. With memory
function, the dimmer switches on at min. light intensity when putting into
service. Afterwards, the dimmer switches at a the last set value.
As a standard, the dimmer is set to function with memory. To modify this
function, press the operating key for 10s. After 10s., the light intensity
drops from 100% to 50% to indicate the standard function has been
deactivated. Immediately let go of this key after this modification in light
intensity. Repeat this procedure to reactivate the memory function. This
function is saved in a permanent memory together with the last set level
of light intensity. They are not lost after a power cut.
In combination with Nikobus: If the dimmer 05-728 is used together
with the Nikobus home automation system, please ensure that the dimmer
05-728 is set to function without memory. This is necessary in order to
prevent the dimmer 05-728 from switching on with memory function after
a long power cut. This is not desirable in combination with Nikobus.
3.4. Safety systems
Thermal protection: this protection will be activated if the internal tem-
perature exceeds 120°C. The dimmer can be operated again as soon as
the temperature has dropped.
Softstart: power surges are electronically reduced.
The triac is switched off if a triggering problem occurs due to excessive
inductions. The dimmer automatically reactivates if the key is pressed.
2.5. Mains connections (top from left to right)
See diagrams. The two terminals at the right are bridged internally. Make
sure all wires have a clearance of min. 5cm from the ventilation slots. The
connection wires can never obstruct the ventilation slots.
Warning: make sure all terminals are well tightened before switching
on the mains. Check the pressure on the terminals whenever mainte-
nance is carried out. The dimmer must be installed in and protected by
a consumer unit.
3.6. Control connections: push button control
Different configurations are possible (see diagrams)
- push button to dimmed phase
- push button to phase: additional external bridge necessary (not supplied)
3.7. Cooling
Cooling is essential for reliable and safe operation.
The dimmer produces ±0,9% heat according to the connected load.
E.g.: 1.000W lighting = 9W dissipation.
Provide appropriate circulation of cool air with regard to the total dissipated
power. If the natural circulation of air is limited, a fan must be provided
in the consumer unit or in the room. Provide a mutual distance of 2cm if
several dimmers are placed next to each other.
Nominal ambient temperature: 35°C.

2.8. Interference suppression
Interference across the feeder cables: interference suppression meets the
European standard EN55015.
3. USAGE WARNINGS
- These dimmers are not suitable for controlling motors unless the specific
safety requirements are guaranteed by external systems (in this case,
automatic restart following an power cut is prohibited).
- Special note concerning inductive loads: if the dimmer is connected to
ferromagnetic transformers, only transformers suitable for dimming can
be used. Transformers should be loaded for min. 75%.
- The total consumption of ferromagnetic transformers must be increased
by the efficiency factor (e.g. efficiency 80% = max. load 800W). The
max. load must be decreased by 20% if the efficiency factor is not
specified.
- The use of toroidal transformers can cause humming.
- The dimmers are never separated electrically from the mains by oper-
ating the controls. All via the mains can interfere with the operation of
the dimmer. This interference only occurs if this signal is sent via the
mains. The dimmer is provided with a built-in filter to suppress this
interference.
