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 an FSA12, of

which one or more central control pushbuttons in the setting ES.

The channels are configured together. Each NO contact has a switching capacity up to

4A /250V AC. Incandescent lamps 1000 watts.

Patented Eltako Duplex technology (DX) allows you to switch normally potential free contacts

in zero passage switching when 230V A/C voltage 50Hz is switched. This drastically

reduces wear. To achieve this, simply connect the N conductor to the terminal (N) and L to

K(L). This results in an additional standby consumption of only 0.1 watt.

If the channels are used to control switchgear that has no zero passage switching, (N) should

not be connected, otherwise the additional off-delay would have the opposite effect.

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 all 4 relays are switched on, a power of 0.7 watts is required.

The upper rotary switch

defines the function of the 4 channels together as impulse switch

with universal switch (

ES-UT), as impulse switch with direction switch (ES-RT), as fleeting NO

contact (

EW) or as relay (ER).

In ES function, central control commands ON/OFF can be taught-in.

In EW function, a wiping time of 2 to 25 seconds can be set.

The middle and the lower rotary switches

are for teaching-in the pushbuttons and if

necessary the four channels will be tested. In normal mode, the two rotary switches are finally

set to AUTO.

When

wireless motion/brightness sensors FBH are taught-in, turn the top rotary switch to

define the switching threshold on the last FBH taught-in. This switches the sensor on or off

in case of motion detected or dependent on the brightness detected (from approx. 30 lux in

position RT to approx. 300 lux in position 25).

If the FBH is taught-in in position ER, it is only evaluated as motion detector.

An off delay of 1 minute is a fixed setting in the FBH.

When

wireless window/door contacts FTK are taught-in, different functions can be set with

the middle rotary switch in position AUTO 1 to AUTO 4 and linked to maximum 32 FTKs:

AUTO 1 = window closed then output active. AUTO 2 = window open then output active.

In settings AUTO 3 and AUTO 4 the FTKs taught-in to a single channel are linked automatically.

With AUTO 3 all FTKs must be closed so that the N/O contact closes (e.g. for climate control).

With AUTO 4 one open FTK is sufficient to close the N/O contact (e.g. for an alarm signal or to

switch on the power supply for an extractor hood).

One or several FTKs can be taught-in in several channels to allow several simultaneous

functions in each FTK.

After a power failure the link is restored by a new signal to the FTK and a signal on the next

status message 15 minutes later.

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.
