n. 1 KNX 4-channel 16 AX actuator with manual control - DIN rail mounting
n. 1 Bus terminal
n. 5 Screw terminals
n. 1 Cover with screw
n. 1 User and installation manual

Briefly

The KNX 4-channel 16 AX actuator with manual control - DIN rail mounting allows up to 4 different electrical loads to be activated/deactivated separately by means of 4 × 16 AX relays, each one fitted with 1 NO output contact. The relay switchover command can come from command devices or sensors of the Building Automation system via the KNX bus or generated locally via the front push Buttons.

The device has an auxiliary 230Vac input that makes it possible to control connected loads through the front push Buttons also without KNX BUS voltage (with 230Vac mains voltage present).

The actuator is powered from the BUS line and is equipped with 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 functioning modes can be used simultaneously by means of distinct communication objects.

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.

Functions

The actuator is configured with the ETS software to create the functions listed below.

Switchover:

• parameterisation of output behaviour (NO/NC)
• timing of stair lights and the possibility of setting its duration via the BUS
• timing of stair lights with switch-off warning function
• delayed activation/deactivation
• blinking

Scenes:

• memorisation and activation of 8 scenes (value 0 - 63) for each output
• enabling/disabling storing of scenes by the BUS

Priority commands:

• parameterisation of the output relay value at the end of forcing

Blocking command:

• parameterisation of the blocking object value and output relay value at the end of blocking

Safety functions:

• periodical monitoring of input object

Logical functions:

• AND/NAND/OR/NOR logical operation with command object (switchover, timed switchover, delayed switchover, blinking) and result of the logical operation
• using the result of the logical operation to enable the command object (swithover, timed switchover, delayed switchover, blinking, scene)
• logic operations AND/NAND/OR/NOR/XOR/XNOR up to 4 logic inputs

Output status:

• parameterisable sending to the BUS

Other functions:

• parameterisation of output behaviour with voltage fall/reset on BUS
• parameterisation of behaviour of local command push Buttons

INSTALLATION

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

Recommendations for installing the KNX

1. The length of the bus in between the aduator and the power supply must not exceed 350 metres.
2. Thelengh of the bus line between the actuator and the furthest way KMX device must note exceed 700 metres.
3. To avoid unwanted signals and overvoltages do notuse ing druits.
4. Keep a distance of atle ast 4mm between the individual lyinsulated cable of the bus line and those of the electricity line (figure C).
5. Do not damage the electrical continuity conduct or the shielding (figure D).

ATTENTION: The bussignal cablesthat are not used and the electrical continuity conductor must never touch any live elements or the earthing conductor!

Assembly on the DIN rail

Mount the 4-channel actuator on a 35mm DIN rail in the following way (figure E):

1. Insert the upper device coupling in the DIN rail.
2. Turn the device and clock it on the DIN rail, using the fixing tab.

Electric connections

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).
3. 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 4mm 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).

Using the local command push-button

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 (default setting). If a priority command is active, the local commands will not be executed. It is possible to configure the behaviour of the local command push-button via ETS

ATTENTION: the local control push Buttons operate also without BUS voltage, providing that the auxiliary 230Vac voltage is present.

Maintenance

The device does not require any maintenance. Use a dry cloth if cleaning is required.

PROGRAMMING WITH ETS SOFTWARE

The device must be configured with the ETS software.

Detailed information about the configuration parameters and their values can be found in the Technical Manual
