Interface Cable
The TUVC-RAD-100DL Radiometer is an advanced, state of the art, UV Radiometer
Warranty
Fresh-Aire UV warrants to the original buyer that the Radiometer shall be free from
defects in material or workmanship under normal use and service for one year.
The warranty is contingent upon proper use of the Radiometer and will not apply
if adjustment, repair or parts replacement is required because of an accident,
unusual physical electrical or electro-mechanical stress, neglect, misure, failure
of electric power, humidity control, transportation, unauthorized repair actions, or
not installed or maintained in accordance with Fresh-Aire UV specifications including
the use of any cable other than the supplied interface cable.
This warranty does not cover any labor or subsequent damage incurred as the
result of a Radiometer failure or indirectly arising from the design, construction,
installation, servicing or operation of the Radiometer.
Buyer must provide proof of purchase. Buyer shall not return to Fresh-Aire UV any
allegedly defective goods without Fresh-Aire UV prior written authorization.
All specifications subject to change due to a continuos program of improvement

Software, Screens and Operation
Upon powering up the unit, the software revision will be displayed
for about 5 seconds. If the “MODE” button is depressed the screen will stop
showing the revision and jump to the next screen.
SCREEN #1: r1-6 (Revision 1.6)
Next, the unit will advance to the default screen to indicate “Pxyz” where “P”
equals the percentage of UV light detected as referenced to the baseline* and “xyz”
represents the value of “P.” See instructions for SCREEN #5 to learn how to set
the baseline.
For example:
SCREEN #2: “P73” (the measured intensity is at 73%
of the maximum set intensity of 100%).
If the optional data logging is installed, after the revision the unit will scroll
“data logger.”
Electrical Connections
Dry Contact Output
To remove a wire from the terminal block, insert a small athead screwdriver above
the terminal and gently pull out the wire.
Under normal operating conditions, the relay is energized.This means that a power
failure will trigger an alarm when the dry contacts are used. This is purposely done
so a power failure in the UV room can be monitored and signaled.
Slot for wire(s) removal
WARNING
Incorrect wiring will damage
the unit and void the warranty.
Make sure to double check all
connections before powering
on the unit.

Screen 5
Tapping the “MODE” key once more will advance the unit to SCREEN #3.
SCREEN #3 will scroll “Intensity xxxx” to indicate absolute UV measured intensity
2 2
times 10, in µW/cm where “xxxx” is the value of measured intensity in µW/cm x 10.
For example:
SCREEN #3: “Intensity 1234” (the absolute measured
2
intensity is 1234 x 10 – 12,340 µW/cm ).
Tapping the “MODE” key once more will advance the unit to SCREEN #4.
SCREEN #4 will display “dxyz” to indicate the number of days elapsed since
the baseline* reset where “d” signifies days and “xyz” is the measured value
of days elapsed.
For example:
SCREEN #4: “d321” (the lamp has been used for 321 days
since the baseline* reset).
*This is to reset the baseline of all measurements with the exception of the absolute intensity
measurement (SCREEN #3).
Tapping the “MODE” key once more will advance the unit to SCREEN #5.
SCREEN #5 will scroll “Hold To Reset”. By holding down the “MODE” key for more
than 3 seconds the radiometer will reset the lamp percentage’s reading to 100%
and days elapsed to 0.

Data logging output (optional)
Mounting the Sensor
Mounting the Controller
If this option is installed, a linearized analog voltage is output with the following
end points:
The data logging voltage will be set according to the baseline reset procedure
outlined above.
The UV sensor must be mounted facing the lamp(s), approximately 3-10” (8-25 cm)
away from the lamp(s). If the radiometer displays “Sensor Saturated” – the sensor
2
has detected UV intensity greater than 21,300 µW/cm . Move the sensor away from
the lamps until this condition is resolved.
Using two screws, mount the sensor on a at, clean surface where no water will drip
directly on the sensor.
For optimal performance be sure to keep the sensor clean. To clean the sensor, we
recommend using a cotton swab and isopropyl alcohol with compressed air.
The controller should be mounted outside of the air handling unit.
Mount in an area with a temperature less than 50˚C and 90% RH.
Mount on a at, clean surface within the range of the cable.
Use two or three screws to mount the controller by using the keyholes in the
back of the controller.
Connect the sensor to the output port of the controller using the supplied cable
Connect power to the controller
0% = 0 Volts
100% = 10 Volts ± 500 mVolts

For example:
SCREEN #5: “Hold To Reset”.After the baseline is reset
by holding down the “MODE” key for more than 3 seconds,
the screen will display “done”.
When the screen changes to “done", indicating that the baseline was reset
SCREEN #2 (percentage) will show 100 (%) and SCREEN #4 (days) will show
0 (days).
Tapping the “MODE” key once more will advance the unit to SCREEN #6.
SCREEN #6 will scroll either “beeper enabled” or “beeper disabled” depending on
the last saved state of the alarm buzzer. To change between states, hold down
the “MODE” button while in this screen for more than 3 seconds.
Screen 6
“Beeper enabled”:
When the beeper is enabled the radiometer will beep when the “MODE” key is
pressed and also when the measured lamp percentage is lower than YYY%,
where “YYY%” equals a factory programmed threshold.
“Beeper disabled”:
When the beeper is disabled the unit will not beep during alarms, but will continue
to beep on key presses.
For example:
The state of the beeper (enabled/disabled) is saved in non-volatile memory and
will not be affected by a loss of power.
SCREEN #6: “beeper enabled” or “beeper disabled”

The following scrolling screens will indicate abnormal operations of the radiometer.
The radiometer will revert to normal operation once the problem is corrected:
1- “Connect Sensor” – a proper sensor is not attached to the radiometer.
To correct this error check that the sensor is properly plugged into the unit.
2- “Sensor Saturated” – the sensor detects UV intensity greater than 21,300
2
µW/cm . To correct this error move the sensor to a more suitable distance from
the UV source being measured.
Error Screens
Factory Programmable Thresholds
Thresholds are expressed by measured lamp percentage.
aa%: Green LED threshold
bb%: Yellow LED threshold
cc%: Blinking RED LED threshold
YYY%: Buzzer threshold
LED color indication:
Green: > aa% of the UV irradiance
Yellow: aa - 1% to bb% of the UV irradiance
Red: < bb% of the UV irradiance
Blinking RED : < cc%
Defaul thresholds:
LED color indication:
Green: 75% - 100% UV Intensity
Yellow: 60% - 74% UV Intensity
Red: 40% - 59% UV Intensity
Alarm: 0% - 39% UV Intensity
