Coupling instructions
1
Select a free address in the DL bus net
2
Press the receiver button for at least 2 seconds
3
Couple the transmitter with the receiver by pressing the button
in the room sensor or inserting the battery.
Supplementary explanations:
1.
A
free address
is selected by brief key presses at the receiver. A free
wireless ad-
dress
can be identified because the relevant LEDs are permanently lit and do not
flash. The same address cannot be used twice in the
DL bus network
. Thus for ex-
ample, if address 1 is already occupied for a FTS4-50DL volume flow encoder, it can-
not simultaneously be used for a wireless sensor.
2.
After selecting the address, press the button for approximately 2 seconds -> the LEDs
start to flash slowly at intervals of a second.
3.
The coupling telegram is sent by pressing the coupling button in the sensor (refer to
the following figure).
The sensor send a coupling telegram to the receiver and "registers itself".
After suc-
cessful registration, the LEDs start to flash more quickly after about 5 seconds.
If the battery is not yet inserted in the wireless receiver, coupling can also be imple-
mented by inserting the battery. If the battery is already inserted in the sensor, then for
a coupling process after removal and insertion of the battery, it is necessary to wait for
about 5 minutes so that the internal voltage supply can be reduced. Removal and im-
mediate insertion of the battery does not generate a coupling telegram.
The sensor must be coupled within a minute of the LEDs starting to flash slowly, oth-
erwise the receiver switches back again (LEDs illuminate continuously).
Likewise, coupling can be interrupted before registration of the transmitter by quickly
pressing the receiver button.
