7. Put the plug of the UV-C device in a wall socket with a safety ground and fitted with a
residual current circuit-breaker. Check whether the lamp is operating by looking through
the transparent components of the unit. The unit is switched off by pulling the plug out of
the socket.
INSTRUCTIONS FOR USE OF THE DIGITAL TIME METER
As soon as the UV-C Pro 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 '4500' 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 4,500 hours. The UV-C lamp operates
at 100% radiation for up to 4,500 hours. After 4,500 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 4,500 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 4500 will
be displayed, and then release it, the time meter will start counting down from the 4,500
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.
