Appendix C Eliminating Faults

If transmission is not received from a sensor for 36 hours, its value disappears
from the display. At regular intervals (17 hours) the PC interface polls all the
sensors during a six minute period in case synchronization between sensor and
PC interface has been temporarily affected by transmission path interference.
Transmission occurs in a very short period of time. After this period any faulty
reception should have been cleared.
Possible faults which prevent correct display of transmitted measured value
data include:
Undefined values after starting up
Ensure that the PC interface is only started up 10 minutes after the last radio
sensor was started up in order to receive defined data immediately and guaran-
tee the correct assignment of the data telegrams to the display positions.
No reception - distance between transmitter and receiver is too great
Reduce the distance between transmitter and receiver.
Repeater for Increasing the Range
Buildings which reduce ranges can be compensated for by means of a special
repeater designed for the weather station. The battery powered repeater, equipped
with transmitter and receiver receives the data from the required sensors and
transfers them on with only a minimum delay. The repeater is housed in a
waterproof casing and is suitable for installation both indoors and out. Several
repeaters can be cascaded to overcome greater distances.
No reception - interfering material between transmitter and receiver (thick
walls, concrete,...)
Find a new location for the transmitter or receiver. Also refer to Appendix D
("Range").
Batteries of transmitter or receiver empty
Change batteries.
Transmitter superimposed by source of interference
(radio, headphones, loudspeakers)
Eliminate the source of the interference or find a new location for the transmitter. If no
data is received for 36 hours, the associated measuring point is deactivated so that
no more measured data is displayed because the system assumes that the sensor
no longer exists. No more attempts are made to receive data in order to save battery
power. Every 17 hours the receiver automatically starts a resynchronization, whereby
sensors which have not been received for over 36 hours are deactivated.
