For installation. 45mm long, 55mm wide, 18mm deep.
Power (24V DC) is supplied by the switch mode power supply unit SNT61-230V/24V DC-0,25A
(33mm deep, 45mm long, 55mm wide). This switching power supply unit simultaneously
supplys the multisensor MS including the heating of the rain sensor.
It is possible to use a deep UP box for the two devices.
This weather data transmitter module receives the seven momentary readings of the weather items: brightness (from three cardinal
points), twilight, wind, rain and ambient temperature by cable J-Y (ST) Y 2x2x0,8 from the multisensor MS attached to the outside
of the building. The readings are sent in the form of wireless telegrams over the Eltako network with the priorities listed below.
When the supply voltage is applied, a teach-in telegram is sent immediately and two status telegrams containing the momentary
values are sent approx. 60 seconds later.
After that, the momentary values are sent every 10 minutes.
Brightness values
West, South and East each from 0 to 150 kLux if a change of minimum 10% occurs.
Twilight values
from 0 to 999 Lux if a change of minimum 10% occurs.
Wind speeds
from 0 to 70m/s. From 4m/s to 16m/s, the momentary values are sent immediately 3 times at intervals of 1 second.
After that, further value increases are sent within 20 seconds. Dropping wind speeds are sent progressively delayed by 20 seconds.
Rain
values at the start are sent immediately 3 times. After the rain stops, a telegram is sent within 20 seconds.
Temperature
values from -40.0‹C to +80.0‹C are sent every 10 minutes together with all the other values in a status telegram.
Evaluation is carried out by the FVS Wireless Visualisation and Control Software, the wireless multifunction sensor relay FMSR12
(in preparation) and the weather data display FWA55D (in preparation).
Monitoring multisensor function and line break:
If the weather data message from multisensor MS is not sent for 5 seconds, the
FWS61 immediately sends an alarm telegram which is repeated every 30 seconds. The alarm telegram can be taught-in as a
switch telegram in an actuator to initiate further action as required. In addition, the two status telegrams containing the values
brightness 0 Lux, twilight 0 Lux, temperature -40‹C (frost), wind 70m/s and rain are sent.
When a message is again detected from the multisensor MS, the alarm stops automatically.
