For your safety

¼

DANGER

Risk of fatal injury from electrical current.

All work on the device should only be carried out by trained and skilled electricians. Observe the country-specific regulations as well as the valid

KNX guidelines.

½

CAUTION

The device could be damaged.

- Only operate the device according to the specifications stated in the Technical data.

- All devices that are installed next to the actuator must be equipped with at least basic insulation.

Getting to know the switch actuator

The switch actuator REG-K/2x230/10 with manual mode

(referred to below as the actuator ) can switch two loads via separate, floating make contacts.

You can switch the actuator to manual operation and check that it works even without ETS programming, and you can control the connected loads directly at the actuator in the event of a bus failure.

The actuator has a bus coupler. It is installed on a DIN rail, 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.

DANGER

Risk of fatal injury from electrical current.

Voltage may be present at the outputs when the mains voltage is connected to the system.

If subjected to strong vibrations during transportation, the switch contacts might change to the enabled state.

After connecting the bus voltage, wait 30 seconds. The relays of the channels will be switched off. Set the relays of the channels to the position desired simply by switching "On/Off".

3 Connect the bus voltage.

4 Wait at least 30 seconds.

5 Set the relays of the channels to the position desired simply by switching "On/Off".

CAUTION

The actuator can be damaged.

Protect:

- Connections with a 10-A circuit breaker connected upstream. If you use separate fuses for the connections of two related switching channels, these must be on the same phase.

Now you can check the functionality of the actuator and the connected loads without having to load the application from the ETS. (See the "Operating the actuator" section.)

Putting the actuator into operation

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.

The operating LED lights up: The application was loaded successfully, the device is ready for operation.

WARNING

Risk of fatal injury from electrical current. The device could become damaged.

Safety clearance must be guaranteed in accordance with IEC 60664-1. There must be at least 4 mm between the individual cores of the

230 V supply cable and the KNX line.

Operating the actuator

Normally, you control connected devices using pushbuttons or by remote control. However, you can also switch the actuator to manual operation and then switch each channel on and off manually using its channel keys. In order to be able to do this, the ETS parameter "Manual operation enabled" must be set to

"enabled" and mains or bus voltage must be present.

Manual operation before downloading the application for the first time

Immediately after the initial installation, you can switch the actuator to manual operation, e.g. in order to test the operation of the connected devices.

Manual operation with the ETS setting "Bus and manual operation"

In manual operation, the actuator also responds to KNX telegrams. The command last received is given priority.

Exception: Safety and security alarms always have priority with this setting.

Manual operation with the ETS setting "Manual operation only"

In manual operation, the actuator does not respond to

KNX telegrams, nor to safety alarms. This setting can be useful when carrying out maintenance, for example.

½

CAUTION

Loads could be damaged.

When operating loads in "Manual operation only" using the channel keys, prioritised safety functions (e.g. priority control) no longer work. To prevent damage, you should therefore be very careful when operating manually.

| Make sure that the ETS parameter "Manual operating mode" is set to "Bus and manual operation" ( not "Manual operation only"), when you hand over the system to the operator.

Time-limited manual operation is another function that can be set in the ETS. With this function, you can set a time period after which manual operation (including

"Manual operation only") is cancelled automatically. The actuator then responds to KNX telegrams again.

How to set the actuator to manual operation

1 Press the manual operation key.

The red manual operation LED lights up. The actuator is in manual operation.

– The green operation LED "RUN" goes out when

"Manual operation only" is set in the ETS.

– The green operation LED remains lit when "Bus and manual operation" is set in the ETS.

How to control the channels in manual operation

1 To switch channels on and off: Press the corresponding channel key.

The corresponding channel status LED lights up when the relay is closed.

How to end manual operation

1 Press the manual operation key again.

The red manual operation LED goes out. The green operation LED lights up. The actuator now only responds to KNX telegrams.

What should I do if there is a problem?

The red manual operation LED and the green operation LED are not lit. Manual operation cannot

.

be activated.

Cause Solution

Bus voltage has failed Check bus voltage

The green operation LED is not lit.

Cause Solution

Check bus voltage The bus voltage has failed.

Application was not loaded properly.

Load it again

The green operating LED does not light up, the red manual operation LED lights up.

Cause Solution

Manual operation is active and "Manual operation only" is set in the ETS. Only manual operation is possible.

There is no fault.

Switch off manual operation

Actuator does not react to the manual operation key, the red manual operation LED does not light up, manual mode is not possible.

Cause Solution

ETS parameter "Manual operation enabled" is set to "blocked". There is no fault.

"Manual operation enabled" is blocked by an object (value=0), there is no fault.

Set the "Manual operation enabled" parameter to

"enabled/enable"

Enable manual operation via object

In manual operation, the actuator does not react to the activation of the channel keys, the red manual operation LED lights up, manual mode is not possible.

Cause Solution

The green operating LED is still lit:

The ETS parameter

"Manual operating mode" is set to "Bus and manual operation", a prioritised function (e.g. block) is activated, there is no fault.

Wait until the higher-level function has been completed, or switch the

ETS parameter "Manual operation type" to

"Manual operation only".

Please refer to the safety note in the "Operating the actuator" section.

In manual operation, the actuator controls connected loads without a channel key being pressed.

Cause Solution

The ETS parameter

"Manual operating mode" is set to "Bus and manual operation". The control command for the actuator came via a KNX telegram. There is no fault.

Switch the ETS parameter

"Manual operating mode" to "Manual operation only". Please refer to the safety note in the

"Operating the actuator" section.
