Operational screens (of monitored version)
While the UV unit type „without sensor“ only displays a start-up display, the UV systems „with sensor“
displays the below listed measurement screens with the UV intensity. The UV intensity screen displays
the [%] value of UV light detected by the sensor.
UV intensity can be affected by:
●
poor water quality
●
scaling on the contamination on the quartz sleeve
●
malfunction of the UV sensor
●
failure of UV lamp or UV lamp expiring
The following screens indicate the UV intensity is dropping.
Below 56 %, the numbers and warning sign turn red and an audible chirp is given by the ballast every
15 seconds. Below 51 %, the screen is solid red and a constant audible alarm is given. This alternates
with a screen indicating “water may be unsafe for consumption”. With the solenoid module, the controller
de-activates the solenoid valve, shutting off all water flow.
