Installation
1.1.1.48
Overload
If the electronic overload protection is activated
(overload or overtemperature as a result of incorrect
installation or inadequate cooling), the set degree of
brightness of the lighting unit reduces. If overload /
vertemperature is applied for a longer time, Dimmer
6591U-101-500, 6594U-500 switches off.
The supply voltage must be disconnected prior to
remedying faults. Check the load on the dimmer
and reduce if necessary.
The dimmer is again ready for operation after
elimination ofthe overload and following an appropriate
cooling-down phase.
Short Circuits
In case of a brief short-circuit of the load, the dimmer
6591U-101-500/6594U-500 disconnects the connected
loads and re-connects them afterwards. In case of a
permanent short-circuit, the dimmer switches off
completely. The supply voltage must be disconnected
prior toremedying faults. After the fault has been
remedied,the dimmer is again ready for operation.
