Combination sensor

Page 2 of 5
Important:
Check the place of installation for optimal reception of
the DCF77 time signal.
Reflexions can cause reception interference.
If no interference-free reception is possible, change
the place of installation by a few meters until the com-
bination sensor receives the time signal without inter-
ference (see chapter „Antenna orientation“).
e
Connection
• The combination sensor is provided with a 10 m-
long connecting cable.
The cable may be extended up to 50 m max. (re-
commended cable: LiYCY 6 x 0.25 mm
2
, shielded).
• Connect the combination sensor to the weather
station (FIG.
f
):
(a) pink:
supply AC/DC 24 V, 600 mA
(b) grey:
supply ground
(c) green-yellow: shield
(1) green:
system voltage DC 24 V, > 15 mA
(2) yellow:
data
(3) white:
sync.
(4) brown:
system ground
• If possible, connect the shield of the combination
sensor (yellow-green, (c)) to earth potential (not to
GND!). If this is not feasible, the shield must remain
unconnected.
When the shield is connected with GND, trouble-
free operation of the device cannot be guaranteed.
f
Commissioning
Commissioning includes logging in of the combination
sensor at the weather station and pointing of the an-
tenna for best reception.
This can be done without a project and before final in-
stallation (e.g. at the workshop).
Log-in of the combination sensor
• Switch on the power. The combination sensor con-
firms that it is ready for operation by two brief tones
repeated every 5 s (FIG.
g
).
