EPSON RESET LAMP TIMER FULL
If you need to reset the lamp change timer prior to the full one year time period expiring due to premature lamp failure, there are special instructions included with all replacement lamps describing the necessary procedure. It is not possible to reset the lamp change timer unless the timer is in the grace period or lamp change alarm mode. The UV power source will emit a solid three-second beep indicating that the reset was successful. The lamp change reminder timer is reset by disconnecting the UV power source from the AC supply, wait for fifteen seconds and reconnect to the AC supply while depressing the timer button. NOTE: The UV lamp is not shut down in this alarm mode and the solenoid valve drive is not disabled. On the 29th day, the UV power source will indicate a lamp change alarm by illuminating the red timer LED continuously and sound the buzzer. Under no circumstances, this grace period does not exceed 28 days. The buzzer reset can be pushed up to 4 times during this 28 day period. Pushing the timer button during this grace period will silence the buzzer for seven days, but the LED will continue to flash. The flashing LED indicates that the timer function is in the 28-day grace period. At the end of the one-year period, the lamp change timer will flash and the buzzer will sound. The annual lamp change timer will run for approximately one full year.
