1 BUS terminal
1 Cover with screw
1 User and Installation Manual

Briefly

The universal dimmer actuator 500VA – DIN rail mounting allows you to command and adjust incandescent lamps, inductive loads (low voltage halogen lamps, via winding transformers) and capacitive loads (low voltage halogen lamps, via electronic transformers).

The dimmer actuator is powered from the BUS line, and has a front LED to indicate the output status (LED not lit up when OFF, green when ON, red if the output is overloaded). The dimmer actuator is used to switch the connected load on and off, adjust the degree of light intensity, perform timed commands, perform priority commands for forcing the output status, memorise and execute scenes. The various operating modes can be used simultaneously.

The dimmer actuator is assembled on a DIN rail, inside electric boards or junction boxes.

Functions

The actuator can be configured with the Easy controller to carry out the following functions:

ACTIVATION AND DEACTIVATION OF LOADS

The dimmer actuator activates (100%) or deactivates (0%) the electric load when it receives the ON/OFF commands sent - for example - from a contacts interface or a push-button panel configured in Cyclic ON/OFF switchover mode or Fronts management mode. The status LED lights up to show the output is active.

BRIGHTNESS ADJUSTMENT

Used to switch the light on and off, or to vary its intensity (increasing from 13% to 100%, or decreasing from 100% to 13%), depending on the commands received from the other KNX devices. The status LED lights up to show the output is active.

The device can accept percentage light intensity commands on its input.

GENERAL DESCRIPTION

EXECUTION OF TIMED COMMANDS

The dimmer actuator activates the connected electric load at full power for the time specified in the Activation time parameter, subsequently deactivating it when this period has elapsed. For instance, this is the setting for the stair raiser light. If the dimmer actuator receives a new ON command with timing during the activation period, the time count starts again from the beginning. If an OFF command is sent before the time has elapsed, the light will be switched off. The status LED lights up to show the output is active. With the Pre-warning time parameter, you can enable the switch-off pre-warning: in this case, the device decreases the light intensity value for the set time leading up to switch-off. You can therefore send a new timed command before the light switches off completely.

EXECUTION OF PRIORITY COMMANDS

The dimmer actuator activates (100%) or deactivates (0%) the commanded load on the basis of the command (ON or OFF) transmitted by the device that sends the priority command. Until it receives a command to annul the forcing, the dimmer ignores all the other commands received (including commands from the front push-button). If no other commands are received, at the end of the forcing the actuator will return to the status it had before the forcing activation. Otherwise, it will adopt the status of the last command received (a light intensity increase/decrease command will be ignored). The status LED lights up to show the output is active.

SCENE MANAGEMENT

The dimmer actuator can memorise and manage up to 8 scenes. The light intensity values can be memorised and called up via Easy devices or conventional push-buttons connected to the BUS via a contacts interface. You can create a maximum of 8 scenes, with varying light intensity values. When it receives the command, the dimmer brings the load to the value previously set. The status LED lights up to show the output is active.

STATUS INDICATOR LED

Status of the LED for output status signalling
OFF	Load not piloted (OFF or adjustment value 0%), and mains voltage present
Green	Load piloted (ON or adjustment value different from 0%), and mains voltage present
Red Output overload
Flashing yellow Mains voltage absent, and BUS voltage present
Flashing red Reset after overload (5 sec)

INSTALLATION

ATTENTION: the device must only be installed by qualified personnel, observing current regulations and the guidelines for KNX installations.

Recommendations for installing the KNX

1. The length of the BUS line between the dimmer actuator and the power supply unit must not exceed 350 metres.
2. The length of the BUS line between the dimmer actuator and the furthest KNX device must not exceed 700 metres.
3. To avoid unwanted signals and overvoltages, do not use ring circuits.
4. Keep a distance of at least 4mm between the individually insulated cables of the BUS line and those of the electricity line (figure C).
5. Do not damage the electrical continuity conductor of the shielding (figure D).

ATTENTION: The unused bus signal cables, and the electrical continuity conductor, must never touch any live elements or the earthing conductor!

Assembly on the DIN rail

Assemble the dimmer on a 35mm DIN rail in the following way (figure E):

1. Insert the upper device coupling in the DIN rail.
2. Rotate the device, then lock it in place on the DIN rail by means of the fixing tab.

Electric connections

ATTENTION: disconnect the mains voltage before connecting the device to the electricity supply!

Figure B shows a diagram of the electrical connections.

1. Connect the red wire of the BUS cable to the red clamp (+) of the terminal, and the black wire to the black clamp (-). Up to 4 BUS lines can be connected to the BUS terminal (same coloured wires on the same terminal) (figure F).
2. Insulate the shield, the electrical continuity conductor, and the other white and yellow wires of the BUS cable (if a 4-conductor BUS cable is being used), that are not necessary (figure D).
3. Insert the BUS clamp in the pins of the device. The correct connection direction is determined by the fixing guides. Insulate the BUS terminal with the special cover, that must be screwed onto the device. The cover guarantees the minimum separation distance of 4mm between the power cables and the BUS cables (figure G).
4. Connect the load to the relevant screw terminals, making sure the current limits specified in the Technical Data are not exceeded.
5. Protect the dimmer by inserting a fuse with high breaking capacity (max. 2.5A) on the power supply line.

Using the local command push-button

The manual command push-button (figure A) allows the cyclical ON/OFF switchover, bringing the light intensity level from 0% to 100% and vice versa every time it is pressed. If a priority command is active, the local commands are not executed.

▶Behaviour upon the failure and resetting of the BUS power supply

When the BUS power supply fails, the device brings the output to the OFF position (0%). When the BUS power supply is reset, the output resumes the light intensity value in force before the power failure.

Overload management

Any possible overload is signalled by a fixed red light on the front LED. During the overload situation, the dimmer output is switched off and every command received from the BUS is ignored. Once the cause of the overload has been eliminated, you can restore normal operation and deactivate the overload signal in the following ways:

• via the front command push-button of the dimmer, and commanding the output. The dimmer will assume the maximum light intensity value and, after about 5 seconds (if the overload has been eliminated), the status LED will switch on with a fixed green light. The front button key allows the dimmer to be commanded even in the event of an overload. During the reset operation (about 5 seconds), the front LED turns red and flashes;
• by disconnecting the 230V AC mains voltage (with the BUS voltage present). When the mains voltage is restored, you can send a command via the BUS or command the dimmer via the front push-button. Regardless of the command received, the dimmer will bring the load to the maximum light intensity value. After about 5 seconds (if the overload has been eliminated), the status LED will switch on with a fixed green light and the dimmer will execute the last command received. During the reset operation (about 5 seconds), the front LED turns red and flashes.

Maintenance

Use a dry cloth if cleaning is required.
