Description

The Cala KNX M-T push button has touch-sensitive buttons, with which functions

in the KNX building bus system can be called, such as switch lights and devices,

dim, activate drives, send values, scenarios. A white LED is integrated into each

touch button, the behaviour of which can be adjusted.

A temperature sensor is integrated into Cala KNX M-T. An external temperature

reading can be received via the bus and processed with its own data to create a total

temperature (mixed value).

Communication objects can be connected by AND and OR logic gates.

The device is supplemented with a frame of the switch series used in the building,

and thus fits seamlessly into the interior fittings.

Cala KNX M1-T functions:

•

1 Touch bus button, can be configured as switch, selector switch, dimmer,

blind (position and slats up/stop OR down/stop), shutters (up/down/stop),

awning (in/out/stop), window (closed/open/stop), as 8 or 16-bit encoder or for

scenario recall/storage

Cala KNX M2-T functions:

•

2 Touch bus button, can be configured as switch, selector switch, dimmer,

for operating drives, as 8 or 16-bit encoder or for scenario recall/storage

•

Area function when touching both push buttons. Can be configured as

switch, selector switch, as 8 or 16 bit encoder or for scenario recall

Cala KNX M4-T functions:

•

4 Touch bus button, can be configured as switch, selector switch, dimmer,

for operating drives, as 8 or 16-bit encoder or for scenario recall/storage

•

Area function when touching two or more push buttons. Can be configured

as switch, selector switch, as 8 or 16 bit encoder or for scenario recall

Function of all models:

•

One LED per touch area. On for object value = 1 / Off for object value = 0, On

after pressing button for settable time or always off. Settable, as to whether

LED flashes at block object value = 1

•

Temperature measurements. Mixed value from own measured value and

external values (proportion can be set by percentage)

•

2 AND and 2 OR logic gates each with 4 inputs. All switching events as

well as 8 logic inputs (in the form of communications objects) can be used as

inputs for the logic gates. The output from each gate can be configured

optionally as 1-bit or 2 x 8-bit

Configuration is made using the KNX software as of ETS 5. The product file can be

downloaded from the ETS online catalogue and the Elsner Elektronik website on

www.elsner-elektronik.de in the "Service" menu. There you will also find the

product manual.

1.0.1. Area function

If the area function in ETS has been activated, another function is available alongsi-

de the regular key functions. This is triggered by touching multiple keys, e.g. if you

touch the sensor with the palm of your hand.

Using the area function

If a key is pressed and another (different) key is touched within 0.2 seconds, the ac-

tion set in the ETS is performed for the area operation (See Fig. 1 a) and b)). The keys

are then blocked for 0.5 seconds.

Using the normal key function

If a key is pressed and no other key is touched within 0.2 seconds, the normal key

function is enabled/provided for 5 seconds (See Fig. 1 c) and d)). This is extended

for 5 seconds with each push of the button.

Installation and commissioning

Installation, testing, operational start-up and troubleshooting should

only be performed by an authorised electrician.

CAUTION!

Live voltage!

There are unprotected live components inside the device.

• Inspect the device for damage before installation. Only put undamaged

devices into operation.

• Comply with the locally applicable directives, regulations and provisions for

electrical installation.

• Immediately take the device or system out of service and secure it against

unintentional switch-on if risk-free operation is no longer guaranteed.

Use the device exclusively for building automation and observe the operating inst-

ructions. Improper use, modifications to the device or failure to observe the opera-

ting instructions will invalidate any warranty or guarantee claims.

Operate the device only as a fixed-site installation, i.e. only in assembled condition

and after conclusion of all installation and operational start-up tasks, and only in the

surroundings designated for it.
