Modular device for DIN-EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep.

Connection to the Eltako RS485 bus, terminals RSA and RSB.

Up to a total of 128 actuators can be added in this way.

Up to 35 pushbuttons each with 4 functions can be assigned to each channel, of which one

or more central pushbuttons.

Switching voltage 230V.

Zero passage switching to protect contacts and consumers.

The 12V DC supply voltage of the complete RS485 bus is mainly powered at 6W, 12W or

24W by a switch mode power supply unit SNT12-12V DC that is only 1 or 2 pitch units wide.

When the relay of the FTN12 is switched on, 0.3 watt are required.

After installation, wait for short automatic synchronisation before the switched consumer is

connected to the mains.

If the function TLZ is set, the lighting is switched on again after a power failure provided the set

time has not yet elapsed.

In addition to the bus control input, this staircase off-delay timer can also be controlled locally

by a conventional 230V control switch. Glow lamp current up to 5mA, dependent on the

ignition voltage of the glow lamps.

The upper rotary switch LRN

is required for teach-in. Then the off-delay 1 to 30 minutes can

be set.

Use the middle rotary switch

in position LRN to assign up to 35 switches and/or wireless

motion/brightness sensors FBH via a wireless antenna module FAM12-12V DC, of which one

or several may be central control switches. The required function of this staircase off-delay

timer can then be selected:

NLZ

= off-delay timer with adjustable operate delay

TLZ

= staircase time switch

ESL

= staircase time switch for energy saving lamps ESL

+ = with pushbutton permanent light (only TLZ)

+ = with switch-off early warning (TLZ + ESL)

+ = with pushbutton permanent light and switch-off early warning (TLZ + ESL)

If the permanent light function

is switched on, the function can be activated by pressing

the pushbutton for longer than 1 second. This function switches off automatically after

60 minutes or by pressing the pushbutton for longer than 2 seconds.

If the switch-off early warning

is switched on, the light starts to flicker approx.

30 seconds before time-out. This is repeated three times at decreasing time intervals.

If both switch-off early warning and pushbutton permanent light are switched on,

switch-off early warning is activated before automatic switch-off of the permanent light.

With the bottom rotary switch

an operate delay (AV-time) can be set at NLZ.

Setting AUTO 1 = 1s, AUTO 2 = 30s, AUTO 3 = 60s, AUTO 4 = 90s und AUTO 5 = 120s (right

stop). Also permanent light function can be set manually.

When teaching-in

wireless motion/brightness sensors FBH, the switching threshold is

defi ned on the last FBH taught-in to switch the light on/off depending on the brightness

provided motion is detected. The off delay set on the FTN12 is prolonged by a setting of

1 minute fixed in the FBH.

When teaching-in

wireless window/door contacts FTK, a NC or NO can be taught-in as required.

Accordingly, the timing period starts when opening or closing the window or the door.

If

switches for permanent operation are taught-in, for example wireless transmitter modules

or FTS12EM, it is switched on when pressing and the time will be started when releasing.

The LED

below the upper function rotary switch performs during the teach-in process according

to the operation manual. It shows control commands by short flickering during operation.
