Lamp failure detection
- Conveyor and transport systems
- Lamp failure detection in a lift car.
- Monitoring of the permitted current range of the lighting with the “under” function.
As soon as the power draw leaves the acceptable range, for example because of a load reduction due to a defective lamp, the relay output is tripped, and the higher-level control system can recognise the fault.
- - Rapid fault detection, quick replacement possible
