5. Connection to a LON-Works network
6. LED displays
Connection to the LON-Works network is made via the pluggable terminal block:
A: Signal A
B: Signal B
GND: Signal earth
Via the service pin, the LON interface can be connected to a LON-Works network.
For this, briefly short-circuit the two contacts of the service pin using a screwdriver
or similar tool while installing the node. All data required to identify the interface is
transmitted to the LON-Works network as a broadcast.
The precise connection procedure depends on the LON-Works management tool
used. Please consult the relevant instruction manual.
The LON interface is supplied with the application files (.xif, .nxe) already installed.
In addition, the files in their latest version are available to download from the Wolf
homepage (www.wolf-heiztechnik.de).
