FREQUENTLY ASKED QUESTIONS

FAQ LCN-SKO

To use the LCN-SKO starter-set you need a standard main power system with at least one phase wire, one neutral wire and one data wire. Connect the modules as shown in the installation manual. If you have any more questions, please contact us or call  our technical hotline under  +49 5066 99 88 44.

How do I see that I have connection to the LCN bus?

The datagram counter shows an increasing number and the bar besides lights in green an shows “Online”.

The outputs do not switch on and off.

Check that the outputs of a module are activated, e. g. Standard (dimm, switch).

What do the four LEDs in the LCN-PKU mean?

In standby mode both green LED are alight. While communication takes places, the two red LEDs flicker. If the two red LEDs light up permanently or when only one green LED lights up, the bus is disturbed. See the LCN-PKU installation manual for more details.

Tipp:

If the LEDs mark phase voltage on the data line, disconnect one circuit after another until the red LEDs go off. In this circuit, there is a wiring failure.

What is the difference between bus modules and other components?

LCN bus modules are connected to the data wire. Their own intelligence allows them to commicate with each other and to control peripherals. Bus modules are LCN-UPP, LCN-UPS, LCN-UPU,LCN-UMR, LCN-SH, LCN-SHS, LCN-HU and LCN-LD. The connected peripherals do not have intelligence and always need a connection to a T-, I- or P-Port.

Which peripherals are recognized by plug-and-play?

In general, all components that are not listed in any menu. For example LCN-GT4D, LCN-GT10D, LCN-GBL, LCN-TS, LCN-B3I, LCN-BT4H, LCN-BU4L and LCN-BMI at the I-Port.

How do I know how to configure a device?

Every LCN product comes with an installation manual. Read it carefully to get to know how to handle it.

How are new modules recognized and configured?

With the right mouse button click on a segment and select “Find additional modules”. LCN-PRO will now search for programmed and unprogrammed modules. If unprogrammed modules are found, they are displayed with theit serial number and hardware type, an icon.

Which IDs can be used?

You can use the module IDs 5 to 254, which means a total of 250 IDs. The IDs 1 to 4 are reserved, 1 for the LCN-PRO.You should never use the maximum of 250 modules per segment, as this will not leave room for extensions.

How do I assigne an ID to a new module?

Click on the module with the left mouse button and assign an ID.

Do I have to remember all the numbers or is it possible to use text?

You can give the module a name with a maximum of 20 characters and a comment with up to 36 characters. Use the location of the module and the connected peripherals like “GF LR Door TS B3I BMI” = ground floor, living room, at the door, connected with …

Recommended is a naming scheme like “lll rrr zzz”, where lll = level, rrr = room, zzz = additional information. In the comment note which devices are controlles by this module. With future changes the modules are easy to identify this way.

Settings for outputs

With these settings you can switch the triacs at zero-crossing or you dimm devices in phase-cut mode. Additionally, the values will be output through the EB (electronic ballast) interface.

Setting outputs to 1%

With dimming values greater than 1% the outputs will switch to 100%. The real dimming values are only output as 0-10 V, DSI or DALI signal.

Setting outputs to PPM (pulse package mode)

With the symmetric pulse package mode (multi period control) the current flow for the triac will be enabled for a sequence of complete oscillations, then for another sequence of oscillations disabled. Defined is the cycle time. The smalles cycle time is 5 seconds, the longest one 645 seconds. The dimming values defines the on/off times.

Example: cycle time = 60 seconds, dimming value output 1 = 20%, -> output 1 is 12 seconds on and 48 seconds off.

Remote control works on tables A/B or B/C?

Every LCN remote control can control 16 keys. For the smallest LCN-RT this can be reached with shifting functions (see installation manual LCN-TR). When using Table A/B eight keys will work on Table A, eight more keys on Table B. The four keys of the LCN-RT work directly as key level 0 on keys A1 to A4. Selecting Table B/C the keys will work on Table B, the later keys on Table C. This can be used, when a connected touch terminal LCN-GT6 shall have other functions as the remote control.
