Figure 6: Reference list KNX dimmer
The icons used to label the dimmer load shows the load type that can be connected
to a dimmer and the electric behaviour of a load:
R = ohmic, L = inductive, C = capacitive
5.2 Troubleshooting
System has switched off.
Cause 1: short-circuit protection has tripped. The power booster behaves like the upstream
dimmer.
Eliminate short-circuit.
i The short-circuit protection is not based on a conventional fuse. Thus the load circuit is not
interrupted electrically.
Cause 2: overheating protection has tripped.
Disconnect system from mains, switch off circuit breakers.
Let system cool down for approx. 15 minutes.
Check the installation situation.
Reduce the connected load.
Switch circuit breakers and system on again.
i Load is initially distributed to the remaining devices. The further behaviour of the system
depends on the dimmer used and the number, utilisation and installation situation of the
devices.
