SpaceLogic KNX Switch Actuator REG-K/4x230/16

Getting to know the switch actuator

The SpaceLogic KNX Switch actuator REG-K/4x230/16 with current detection and manual mode (referred to below as the actuator) can switch four loads via separate, floating make contacts.

You can also manually switch the connected loads with manual switches on the actuator without bus voltage. The actuator has a bus coupler. It is installed on a DIN-rail TH 35 according to EN 60715, with the bus connection made via a bus connecting terminal. It is supplied with power from the bus voltage. A data rail is not required.

The actuator also has integrated current detection which measures the load current of each channel.

Connections, displays and operating elements

• A Bus connecting terminal, max. 4 core pairs
• B Cable cover
• C Programming button
• D Programming LED (red LED)
• E Operational LED "RUN" (green LED)
• F Manual switch
• G Screw terminals

Art. no. MTN647595

For your safety

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Safe electrical installation must be carried out only by skilled professionals. Skilled professionals must prove profound knowledge in the following areas:

• Connecting to installation networks
• Connecting several electrical devices
• Laying electric cables
• Connecting and establishing KNX networks
• Safety standards, local wiring rules and regulations

Failure to follow these instructions will result in death or serious injury.

DANGER

RISK OF FATAL INJURY FROM ELECTRIC SHOCK

The output may carry electrical current even when the load is switched off.

When working on the device: Always disconnect the device from the supply by means of the fuse in the incoming circuit.

Even if the manual switch is in the "OFF" position, a KNX telegram can switch the connections to being live at any time. Before working on the device, always disconnect the fuse in the incoming circuit from the supply.

Failure to follow these instructions will result in death or serious injury.

CAUTION

The device may be damaged!

• Always operate the product in compliance with the specified technical data.
• Do not use the current detection function for applications relevant to safety.
• Connect only pure ohmic loads to a channel with direct current (DC).
• Only install devices with at least basic insulation next to the device.

Failure to follow these instructions can result in equipment damage.

Mounting the actuator

CAUTION

Strong magnetic fields can influence the current measurement. Install devices with a strong magnetic field (e.g. wound transformers such as bell transformers) at least 2 cm away from the actuator.

1. Set the actuator onto the DIN rail.
2. Connect the mains voltage.
   Diagram: Shows a connection to L1, L2, L3, N with terminals for 16A loads.
3. Connect the bus voltage.
   Diagram: Shows KNX connection terminals.
4. Wait at least 30 seconds.
5. Set the relays of the channels to the position desired simply by switching "On/Off" or by changing the manual switch to "OFF".
6. Connect the load.

You can now check the function of the connected load using the manual switch, without having to load the application from the ETS. (See the "Operating the actuator" section.)

Commissioning the actuator

1. Press the programming button. The programming LED lights up.
2. Load the physical address and application into the device from the ETS. The programming LED goes out.
3. The operational LED lights up: The application has been loaded successfully, the device is ready to be operated.

Operating the actuator

Connected devices are usually controlled using push-buttons or by remote control. However, you can manually switch each of the actuator's channels on and off directly at the manual switches.

What should I do if there is a fault?

The green operational LED "RUN" is not lit.
