INSTRUCTIONS FOR USE OF THE DIGITAL TIME METER
As soon as the Blue Lagoon Pro UV-C is switched on, the program will carry out a self-test. The
display will automatically show the following , one after the other: 8888 (display test) ; r and
software version number ; 50H or 60H indication of the mains frequency.
Following this, the display will show the meter reading.
When the UVC lamp is switched on for the first time, or after the "reset" function has been used, the
value '9000' will appear on the display. A dot next to the digit on the far right of the display will blink
every second; this indicates that the counter is running.
The display is automatically set to the factory reading of 9,000 hours. The UV-C lamp operates at
100% radiation for up to 9,000 hours. After 9,000 hours, the radiation will weaken, and may become
insufficient to obtain the desired results.
If the UV-C lamp had already been used previously, and is switched on again, the display will
indicate the value it had at the time it was switched off earlier. If you had increased or reduced the
value of the time meter yourself, the display will indicate the latest counter reading it had before it
was switched off.
The settings of the time meter can be modified if you wish. This is carried out as follows:
After holding down the switch (R) underneath the display for 5 seconds, the display will show "rSt",
to indicate that the user menu has been selected. Once the switch (R) has been released, the meter
indication and "rSt" will blink alternately on the display. By briefly pressing the switch again, it is now
possible to step through the menu options. There are 3 available setting options in the menu: "rSt"
"UP" and "dn".
• "rSt" means (reset): This option enables you to reset the meter indication to the factory setting
of 9,000 hours.
This selection is confirmed if the meter indication and "rSt" on the display blink alternately. If you
hold down the switch (R) for 5 seconds, after which the meter indication 9000 will be displayed,
and then release it, the time meter will start counting down from the 9,000 hour value. This
selection is used if, for example, you have replaced the lamp, or if you have modified the meter
indication yourself and you want to return it to the factory settings.
• "UP" means (up): This option enables you to increase the meter indication to the desired hour
indication.
This selection is confirmed if the selected user setting "UP" and the meter indication on the
display blink alternately. Following this, press the switch (R) down for 5 seconds. After 5 seconds,
the display will only indicate "UP". You can then release the switch.
By briefly pressing the switch , the counter value can now be increased in steps of 500 hours
from the value of 9000 up to a maximum value of 9999. The increased value and "UP" will blink
