UV POWER SOURCE FEATURES
The microprocessor controlled power source supplied with your Excelight System
has both visual and audible alarm enunciation to indicate lamp operation/failure
and an integral annual lamp change reminder timer.
UV Power Source Initialization Sequence
When AC power is applied to the UV power source, the lamp is ignited as
indicated by the
green
Lamp-On LED after which a self test of the annual lamp
change reminder timer and lamp illumination. For model before February 2011,
three buzzer beeps and three times
red
timer LED flashes from UV power source
will be noticed. If a solenoid valve is connected to the UV power source, it will
activate on the completion of the self test sequence.
Normal Operation:
During normal operation, the
green
Lamp-On LED is illuminated.
Lamp Failure:
When the UV power source detects a lamp failure or enters the auto shut down
mode due to abnormal operating conditions, Lamp Life Days display freezes, the
red
LED light flashes and an audible alarm is activated. The system will remain in
this state until a new lamp is detected. (See “Replacing the UV Lamp and
Cleaning the Quartz Sleeve” in the Operating and Maintenance section)
NOTE:
The UV power source is designed to shut down if the AC input voltage is
outside its operating limits. When a lamp failure alarm is activated you
should unplug the unit from the AC power source, wait fifteen seconds and
then reconnect the AC power source. If the failure was due to the “Out of
Limits AC Power”, the unit will re-ignite the lamp and operate normally.
Lamp Life Days/Total Running Days:
The screen on the UV power source displays the countdown of system operating
days remaining from 365 to 1 during normal operation. At “0” day, screen will
display “A3” with a flashing
red
LED light, and an audible alarm will be activated.
This indicates a UV lamp changing is required. At this state, the alarm can be
deferred up to 4 times: press and hold the push button on the power source for 5
seconds till screen displays “7”. This will silence the audible alarm for another 7
days but the
red
LED light will still flash. After the final “7” days, the alarm ONLY
can be terminated by replacing a new lamp and resetting the Lamp Life Days
back to “365”. (See “Resetting the UV Power Source” in Operating and
Maintenance section)
The UV power source also tracks total running days of the UV system. To
activate, press the push button for less than 2 seconds, then the screen will
display the total running days of the UV system for 10 seconds and return to its
default screen display (Lamp Life Days).
