2. Technical faults
A technical fault is displayed through a red warning light. The system shuts down and the operating
hours counter (relative hours) stops. Furthermore, the potential-free output as well as the optional
solenoid valve is switched to the free use by the operator.
Malfunctions and other interruptions in operation are detected by the UV sensor and in case of the
intensity falling below 60% they are triggered. If the intensity is reaching 70% again the fault signal
gets inactivated and the system re-starts operation.
Possible failure reasons Trouble-shooting
Contamination of quartz tube insert Clean; remove deposits
Contamination of UV sensor Clean; remove deposits
Malfunction of UV sensor Replace UV sensor
Prematurely ageing or malfunction of UV lamp Replace UV lamp
Accumulation of air in area of UV sensor Let the system ventilate
Too strong turbidity of water (e.g. by means of
faulty pre-treatment) Ensure sufficient water quality with high UV
transmission
Additionally, a failure of electrical parts can appear too in the control unit box. Such damages may for
example occur in case of overvoltage.
