Coupling appliances using externalBus

Important
Because of polarity sensitivity, always connect the external Bus contacts X15-1 with one
another, and the contacts X15-2 and the contacts X15-3 with one another. Never connect
X15-1, X15-2 or X15-3 with one another!
Comment: If a Plus pcb has been installed; several cables would have to be connected onto the
X-15 connector.
Note: When the total length of the external Bus cables is longer than 10 m, then use a twisted-
pair cable for connection X15-2 & X15-3 (a twisted pair cable is also preferred with shorter
lengths)!
For M (master):
Step no. 8.1 - Master
Step no. 14.1 - external Bus
A = Multiple switch
B = 3-pole connector red
C = Modular cable
D = 3-core low voltage cable
M = Master appliance (For example a CWL appliance type 4-0)
S1 / S2 = Slave appliances (For example a CWL appliance type 4-0); connect maximum of 10 appliances
via external Bus
All CWL -2-400 appliances have the same air flow rate as the appliance that is set as "Master".
The fault messages of all appliances are shown on the display of the master appliance.
When using a Bedienmodul BM-2 or the Home, always connect this to the Master.
After connecting the cables configure each CWL -2-400 appliance:
- Enable "External Bus" in menu 14.1 "Type of Bus connection" where shortly after the network symbol
appears.
- Configure each slave in menu 8.1 "Appliance setting slave 1, slave 2 etc where shortly after the M
symbol appears on the master appliance and S1, S2 symbol on slave appliances
- Power down and up all appliances.
Note: Any accessory such as moisture sensor, position switch, extension board or any eBus device must be
connected to the CWL -2-400 master appliance only.
