No wireless connection, even
though the wireless modules are
not far away from each other
• Make sure that in a network only one wireless module is configured
as the master (RAD ID = 01) and all other wireless modules are
slaves or repeaters. Reconfigure the wireless network, if necessary.
• Check whether the set RAD ID is a permitted address.
• Make sure that each RAD ID (yellow thumbwheel) only occurs once
in the network.
• There may be an overload problem: by default upon delivery, the re-
ceive preamplifier is activated. The transmission power is set so that
the devices can cover the greatest possible distances. If the devices
are operated directly next to one another the receiver may therefore
become overloaded. In this case, remove the antennas, increase the
distance between the devices and antennas or reduce transmission
power using the PSI-CONF software (from page 38 onwards).
• Using the PSI-CONF software, check whether the network parame-
ters have the same settings on all wireless modules (operating
mode, network ID, RF band, data rate of the wireless interface, en-
cryption, network type, from page 38 onwards).
• Reset the wireless module to the default settings (I/O data mode), if
necessary. To do so, disconnect the device from the supply voltage,
hold down the SET button, and switch the supply voltage on again
(see page 30).
No wireless connection, the
wireless modules are far away
from each other
• Check whether the antennas are connected and aligned properly.
• Make sure that the antenna connections are tight and free from cor-
rosion.
• Install the antenna at a higher point. Adhere to the Fresnel zone.
• Use a different antenna with higher antenna gain or use shorter ca-
bles with lower signal attenuation.
• Check whether there is another transmitting antenna in close prox-
imity. Position the antenna further away from all other antennas (at
least 1 m in the horizontal direction or 0.6 m in the vertical direction).
• Make sure that the power supply is sufficiently high.
• Make sure that there is no connection between the core and the
shield of the cable in the connected antenna system.
