Ekinex KNX EK-CA1-TP Краткое руководство по эксплуатации

Environmental conditions

• Operating temperature: - 5 ... + 45°C

• Storage temperature: - 25 ... + 55°C

• Transport temperature: - 25 ... + 70°C

• Relative humidity: 95% not condensing

Switching, display and connection elements

The device is equipped with a programming pushbutton

and a programming LED, membrane pushbuttons, LED

for status indication and terminals for connecting the KNX

bus line and the inputs.

Switching elements

• Pushbutton (3) for switching between the normal and

programming operating mode

• Pushbutton (6) for switching between the operating mo-

des: forced (pushbuttons on the front panel: active) or

automatic (pushbuttons on the front panel: not active)

• Pushbuttons (2) for forced operation of the input con-

nections

Switching to the forced operation mode allows to simulate

the state of the inputs with the pushbuttons on the front

panel of the device; in this way it is possible to test the

correct operation of the coordinated loads before connec-

ting any device to the input terminal blocks.

Display elements

• Red LED (4) for displaying the active operating mode of

the device (on = programming, off = normal operation)

• Green LEDs (8) for displaying the switching status of

the input channels (on = closed contact, off = opened

contact)

• Red LED (7) for displaying the operating mode (on =

forced operation, off = automatic operation)

2) Pushbuttons for forced operation of the inputs

3) Programming pushbutton

4) Programming LED

5) Terminal block for KNX bus line

6) Pushbutton for toggling between manual and automatic operation

7) LED for indication forced / automatic operation mode

8) LED for status indication of the inputs

Note. In case of failure of bus voltage, the control of

the loads is not possible with the devices connected

to the binary input. It is still possible if the coordina-

ted KNX actuators are equipped with pushbuttons

or other control manual devices and is present the

mains voltage 230 Vac.

Mounting

The device has degree of protection IP20, and is there-

fore suitable for use in dry interior rooms. The housing is

made for rail mounting according to EN 60715 in boards

or cabinets for electrical distribution. The installation is in

horizontal position, the correct position is when the KNX

bus terminal is located at the bottom and the terminals for

the inputs are located at the top. For the installation of the

device on the rail proceed as follows:

• with the aid of a tool bring the locking device in the fully

lowered position (1);

• place the upper edge of the rear inner profile on the

upper edge of the rail (2);

• rotate the device towards the rail (3);

• push the locking device upward until it stops (4).

Before removing the device, be sure the inputs have been

disconnected and the bus terminal has been extracted

from its slot. Use a screwdriver to slide down the locking

device and remove the device from the rail.

Note. It is recommended that the installation of the

device always ensure the full accessibility of the

front side to allow the operation of the membrane

pushbuttons.

Connection of the KNX bus line

The connection of the KNX bus line is made with the ter-

minal block (black/red) included in delivery and inserted

into the slot of the housing.

Characteristics of the KNX terminal block

• spring clamping of conductors

• 4 seats for conductors for each polarity

• terminal suitable for KNX bus cable with single-wire

conductors and diameter between 0.6 and 0.8 mm

• recommended wire stripping approx. 5 mm

• color codification: red = + (positive) bus conductor,

black = - (negative) bus conductor

Warning! In order to supply the KNX bus lines use

only a KNX bus power supply (e.g. ekinex EK-AB1-

TP or EK-AG1-TP). The use of other power supplies

can compromise the communication and damage

the devices connected to the bus.
