5.1.1 Lamp Life Remaining (days)
The controller tracks the number of days of operation of the lamp and the controller. The default screen will display
the total lamp life remaining (in days). The controller will count down the number of days remaining until the lamp requires
changing (365 days to 1 day). At "0" days, the controller will display
(1 second on, 5 seconds off), indicating the need to change the lamp.
5.1.2 Understanding your "A3" Code
DEFERRAL - Once the "A3" or end of lamp life message is shown on the LED display, the audible alarm can be
deferred up to 4 separate times. The delay is designed to allow you time to address the alarm while you obtain a new UV
lamp. This can be done by simply depressing the timer reset button for 5 seconds, which is located on the left side of the
controller. Each time the timer reset button is pressed the controller alarm is deferred seven days. Once the final 7 day
deferral has been reached the alarm can only be silenced by changing the UV lamp and manually resetting the controller
timer, refer to Section
5.1.3 Resetting Lamp Life
Refer to Section 4.1.
Note: Even though the alarm on the system can be deferred for a period of time, it is important to address each and every
alarm condition as they are indicating that there is a potential problem with the system and should be remedied.
5.1.4 Total Days of Operation
The controller also displays the total running time of the controller. To obtain this reading, press the push-button
once. The total running time of the controller will be numerically displayed in days. This information will remain displayed
for ten seconds and will then revert back to the lamp life remaining default screen. It should be noted that this value cannot
be reset.
5.1.5 Lamp Failure (Blank Screen)
When the system recognizes UV LAMP FAILURE (no current running through the lamp), the display will be blank
(no default UV LAMP LIFE REMAINING screen) and the system will sound an intermittent audible tone
(1 second on,1 second off). The system will remain in this state, until this condition is remedied.
5.2 Plus Systems Incorporating BA-ICE-CM Power Supply
5.2.1 UV Intensity (%)
The VIQUA Plus series of products incorporate a UV sensor which detects the discrete 254 nm wavelength of the
UV lamp. This information is relayed to the VIQUA controller and is the default display shown in "% UV output". The system
will display the UV output between 50 to 99 percent. When the system drops below 50%, a low UV warning is displayed as
and alternately flashes (at 2 second intervals) back to the actual UV level. Eg.
