d) Standard UV Monitor (Optional)
Operation
The UV Monitor option consists of a UV sensor probe, a UV Monitor Board, and a UV digital display. UV
light output is measured from Lamp #1 at the top of the cylinder by the UV sensor probe, a signal is sent to
the UV Meter board for processing, and displayed as a percentage value from 0-100% on the digital
display. When new lamps are installed, the board must be calibrated for the new lamps to 100%. As the
lamps age and UV intensity falls, the UV display will reflect the lowered UV intensity. When the UV
intensity falls below the set trip point, the meter board relay will trip, sounding an audible alarm,
illuminating the Low UV lamp on the display, and switching the state on the contact outputs on the board.
Calibration
The ultraviolet meter can only be calibrated when the power switch is in the ON position and lamps are op-
erational. Lamps must warm up for three minutes prior to any calibrations. Re-calibrate after the lamps
have been operational for 100 hours; when the lamps are stable.
The board’s initial state will be in the fault state. The Low UV light will be lit and the alarm will sound
and the relay will be in the normally open condition. The reason for this state is to allow for lamp
warm-up if the unit is equipped with a solenoid valve. If the unit is equipped with a solenoid valve, the lamps
will be on, but the coil in the solenoid will be de-energized for three minutes to prevent water flow until the
lamps are warmed up and to proper intensity.
After three minutes, the board will revert to the operational “normal” state. If the system is at or
above minimum intensity, the relay will revert to the normally closed position, the Low UV light will go off,
the alarm stop sounding, and if equipped with a solenoid valve, the valve will open and water will flow.
