The switchover command of the relay can arrive from command devices or sensors of the Home Automation system, via the KNX BUS, or be locally generated by the front push-buttons. The actuator is powered from the BUS line and has 4 front green LEDs for signalling the output status. The device sends information to the bus about the relay status (ON = contact closed, OFF = contact open) when switching on, receiving a command and in the case of a command from a local push-button. Each output channel of the actuator can be configured separately and allows the ON/OFF command of the controlled loads, execution of timed commands, scene management and execution of priority commands to force the output status. The operating modes can be used simultaneously. This means, for instance, that the device can switch a light on and off, or automatically switch it on and off after a certain pre-established time, simply on the basis of the command received. The module is assembled on the DIN rail, inside the electric boards or junction boxes. Each channel of the actuator can be configured with the Easy controller to carry out the following functions:

LOAD ACTIVATION AND DEACTIVATION

The actuator channel activates or deactivates the electrical load when it receives the ON/OFF commands sent, for example, from a contact interface or from a push-button panel configured as Cyclic ON/OFF switchover or Fronts management. The green LED turns on when the relay contact is closed.

EXECUTION OF TIMED COMMANDS

The actuator activates the electrical load connected for a time set with the Switch-on time parameter, deactivating it when this time is up. This is the setting, for instance, for the stairs light. If, during the activation period, the actuator receives a new ON command with timer , time starts again from the beginning. Briefly Functions19

GENERAL DESCRIPTION When an OFF command is received or when a scene is activates that includes the actuator OFF command, the relay is deactivated and the countdown cancelled. The switch-off warning can be enabled with the Prewarning time parameter: in this case the relay opens briefly (the light turns off momentarily) when, at the end of the time set, there is the time left set by the parameter. It will thus be possible - if necessary - to send a new ON command with timer before the light turns off. The green LED turns on when the relay contact is closed.

EXECUTION OF PRIORITY COMMANDS

The actuator switches the relay to the (ON or OFF) state transmitted by the device (contact interface) that sends the priority command. Until it receives a command to stop forcing, the actuator ignores all the other commands received including those from the front push-buttons. If no other commands are received, when forcing is finished the actuator returns to the state before forcing was activated. Otherwise, it will return to the state corresponding to the last command received. The green LED turns on when the relay contact is closed. SCENE MANAGEMENT Each actuator channel can store and execute up to 8 scenes, each scene associated with the ON or OFF status of the relay. It is not possible to associate a scene with a timed activation. To associate an actuator status with a scene it is necessary to control the output of the status required (ON/OFF) prior to storing. The green LED turns on when the relay contact is closed.20 INSTALLATION

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

1. The length of the bus line between the actuator and the power supply must not exceed

2. The length of the bus line between the actuator and the furthest away 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 4 mm 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 bus signal cables that are not used and the electrical continuity conductor must never touch any live elements or the earthing conductor! Mount the 4-channel actuator on a 35 mm DIN rail in the following way (figure E):

1. Insert the upper device coupling in the DIN rail.

2. Turn the device and lock it on the DIN rail, using the fixing tab.

Recommendations for installing the KNX Assembly on the DIN rail21

INSTALLATION ATTENTION: disconnect mains voltage before connecting the device to the mains! Figure B shows a diagram of the electrical connections.

1. Connect the red wire of the bus cable to the red terminal (+) of the terminal and the

black wire to the black terminal (-). 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).

Insert the bus terminal in the device's pins. The correct insertion direction is determined by the fixing guides. Insulate the bus terminal with the cover to be screwed onto the device. The cover guarantees the minimum separation distance of 4 mm between the power cables and the bus cables (figure G ).

4. Connect the loads to the relevant supplied screw terminals, making sure the current

limits specified in the Technical Data are not exceeded. Insert the terminals in the actuator output connectors, and check they are correctly inserted (figure H).

1. Power the device via the bus.

2. Follow one of these procedures for the system to acquire the device:

• Automatic acquisition: - select the "Find/Configure" or "Scan" command on the "System" menu

PROGRAMMING WITH THE EASY CONFIGURATOR

1. Power the device via the bus.

2. Follow one of these procedures for the system to acquire the device:

• Automatic acquisition (the device still has the factory default settings): - choose the "New Function Application" → or the “Edit Function → Application" menu from the Easy base unit: the device is recognised automatically.

• Manual acquisition (factory default settings have been changed): - choose the "Find Device Application" → from the Easy Base unit; - press the programming key briefly (< 2 seconds). The programming LED turns on during the acquisition process (figure A). The device acquired by the Easy base unit is listed, with the number assigned to it, in the channels of the “New Function → Application" or “Edit Function → Application" menu. Programme the actuator with the Easy controller (GW 90 837 / GW 90 838 / GW 90 840) or with the Easy base unit (GW 90 831). Each output to programme can be selected as wanted:

• pressing the local command push-button: this channel will then be highlighted on the list of channels;

• directly from the list of channels. The functions can be created once the devices have been selected. For more details about the programming procedures please refer to the Easy base unit or Easy Controller documentation.

IN SERVICE With the local command push-buttons (figure A) you can control cyclic ON/OFF switching over, reversing the status of the relay each time it is pressed. If a priority command is active, the local commands will not be executed. ATTENTION: the local command push-buttons will only work if BUS voltage is present. If BUS voltage drops below 18 V dc for more than 1,5 ms the actuator, with the factory default settings, will not carry out any changes to the status of the output contacts. The behaviour of the outputs when BUS voltage drops can be configured in the following way. Configuration mode input:

• press the programming key: the red programming LED turns on

• press the local command push-buttons 1 and 4 simultaneously for at least 3 seconds

• wait until the 4 LEDs blink once When you are in the configuration mode, the contacts of all the channels are opened and the LEDs show the current configuration status of each single channel, as per the table. The setting of each single channel can be changed with its relative key, so as to scroll all the configurations available in sequence. Using the local command push-button Behaviour of supply fall/reset on the bus CHANNELS 1..4 LED4 CHANNEL STATUS WHEN VOLTAGE DROPS Off Open On Closed Blinking No change26 IN SERVICE Maintenance The device does not require any maintenance. Use a dry cloth if cleaning is required. Configuration mode output:

• to save the new settings: press the programming push-button. The programming LED turns off;

• to exit without saving the settings: wait 10 seconds (from when you last pressed a button). The end of the configuration mode is signalled when the programming LED turns off. When you exit the configuration mode the status of the channels before accessing the procedure is restored. In this configuration phase, the messages from the bus are ignored (they are managed when configuration is exited). When bus voltage is restored the contacts stay in the state they were in when voltage dropped.E
