rises in the UV chamber. This should change back to
Green
when water is being
used.
Lamp Failure:
When the UV power source detects a lamp failure or enters the auto shut down
mode due to abnormal operating conditions, the Lamp Operation Hours timer will
freeze and “LAMP FAILURE” will show on the LCD display. The
Red
LED will
illuminate. If a solenoid valve is connected to the UV power source, it will close on
an alarm condition.
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.
Total Running Hours:
The UV power source tracks total running hours of the UV system. The timer shows
00000 hrs on the display at the system’s initial start. The
Red
LED will be lit when
the timer is approaching the maximum lamp service life 9000 hours. Indicating it is
time to replace the lamp. If an optional solenoid is used on the system, it will close
when the lamp reaches 9000 hrs. It will remain closed until a new lamp has been
installed and the lamp hour timer reset.
Chamber High Temperature Valve:
When the temperature of the water in the chamber exceeds 57
˚
C (135
˚
F); the
thermal relief valve will open until the water temperature goes back to under 57
˚
C
(135
˚
F).
Solenoid Valve Output
(Optional)
The UV power source can power a solenoid valve directly, which will stop the water
flow during any system malfunction. The output is 120 vac - 1 amp maximum.
