JUV 10 - 110 G: The LC display shows the operating hours and any faults (LED alarm flashes). Faults can
be detected via the potential-free changeover contact while at the same time flow can be interrupted by the
JUDO solenoid shut-off valve (service valve) connected to the potential-free changeover contact (230 VAC).
The control unit and hence the UV disinfection system is in operation when connected to the mains power.
JUV 10 - 110 GS: Like the JUV 10-110 G but with an additional operation display for the sensor signal (mV),
radiation strength (%) and temperature (°C). In addition, there are the fault indications for low radiation
strength (Low UVC %) and high radiation chamber temperature (High Temper.).
4.7.1
Remote input
The UVC lamp can be switched on and off via a potential-free contact (e.g. flowmeter, timer, GLT, etc.) to be
connected to the Remote input by the customer.
Attention
If the UVC lamp is switched on via the Remote input, any 230 VAC service valve
connected at the output will remain open.
Make sure that the maximum permissible switch interval (3x per day) is not exceeded,
since frequent turning on and off will significantly reduce the life of the UVC lamp (see
Section 6.2.4 for possible delay time).
In the event of failure to comply, JUDO Wasseraufbereitung GmbH will not be
responsible for the resulting damage, the operator alone bears the risk!
4.7.2
Function monitoring
The monitoring system reacts immediately if the UVC lamp fails and/or its radiation strength is too low
(model JUV 10-110 GS only). The system essentially consists of analysis electronics, an alarm status
indicator, text display and UV sensor (model JUV 10-110 GS only). The permanent measurement of the UV
radiation strength (254 nm) combined with the function monitoring of the UVC lamp, ensure a high level of
reliability with the JUV 10-110 GS model. The alarm threshold for the UV radiation strength permanently set
by the customer ensures the correct minimum UV dose.
The flow can be interrupted via a JUDO solenoid shut-off valve (service valve) connected to the potential-
free changeover contact (230 VAC). Faults detected at the potential-free changeover contact can be
forwarded to e.g. a building control system.
