The 7-UVC Electronic Ballast (a.k.a. EPS-Electronic Power Supply or simply "controller")
is equipped with visible and audible operation indicators:
LAMP-ON INDICATOR -
Steady "work" green LED.
LAMP LIFE REMAINING (DAYS) -
Default count down display (365 - 0); manually reset - see * below.
BALLAST TOTAL RUNNING DAYS -
Incremental display (0-9999); cannot be reset. To view, press
and hold button for 2 seconds, release button and LED display will show ballast total days running. After 10
seconds, the LED display will automatically return to default display (lamp life) or shortly press and hold button
again (2 seconds) before 10 seconds elapse to return to the default (lamp life) display.
LAMP REPLACEMENT REMINDER -
The 365 day countdown timer displays the number of days
remaining until lamp replacement is required. When the countdown timer reaches 0 days an audible alarm
sounds (1 second BEEP every 5 seconds), the red LED flashes and the display will indicate alarm A3.
LAMP REPLACEMENT REMINDER DELAY -
To allow time for obtaining a replacement lamp, the
audible alarm can be silenced for 7 days by pressing and holding the button for 2-5 seconds. The display will
continue to show A3 and the red LED will continue to flash. After 7 days, the audible alarm will sound again
if the lamp has not been replaced. The alarm can be silenced up to 4 times (28 days). After 4 times, the alarm
can no longer be silenced until a replacement lamp is installed and the lamp life timer is reset.
RESET LAMP LIFE TIMER AFTER LAMP REPLACEMENT -
After replacing the lamp by following
instructions on the previous page, reset the lamp life timer to 365 days by pressing and holding the button for
10 seconds... LED displays "rSEt"... keep holding button until LED displays 365 and alarm sounds (1 BEEP).
Release button.

LAMP FAILURE INDICATOR -
In the event of a failure of the lamp (no current running through the lamp),
an audible alarm sounds (1 second BEEP every 1 second), the red LED flashes and the display continues to
show lamp life remaining days but stops counting down (ballast total running days continues counting).
The audible alarm cannot be silenced.
Please note that if this condition occurs and you are on a non-municipal water source, you should immediately
stop using the water for potable applications until the lamp is replaced and distribution lines are disinfected.
BALLAST FAILURE INDICATOR -
Blank display.
Please note that the lamp has an approximate life of one year. Although the lamp will continue to operate
long past one year, the UV output continually decreases after one year and may no longer provide adequate
disinfection. Use only Lancaster Water Treatment lamps to ensure proper operation and performance.
