5.4.2 Maintenance Menu
In this configuration the system can work and the lamp remains on but no alarm will switch. In this way
the user can do maintenance (work on the sensor without alarms that may close the valves).
5.4.3 Sensor Calibration
Irradiance in %
With this operation the user confirms that the signal read by the UV sensor matches the 100% of the
irradiance of the lamps.
IMPORTANT
:
The sensor must be calibrated on every lamp replacement.
IMPORTANT
:
To calculate the IRR. FACTOR. it’ s important the sensor calibration in steady condition (the
time depends on the quality of water, it is about 30 min).
Irradiance in W/m
2
(or Dose in J/m
2
):
The same operation is possible if the system expresses the irradiance in W/m
2
(or the Dose in J/m
2
).
In this case the calibration can only be done by authorized peoples and with a reference sensor.
The association of the sensor signal with the real Irradiance (W/m
2
) is done by the factory. Once time
per year the user should send the sensor to the factory to be calibrated.
5.4.4 Manual cleaning
With this operation the user can move the cleaning system in both the directions. Push ok then move up
and down to chose the direction. Direction 1
2 (means from end switch 1 to end switch 2). If the
cleaning rack is arrived at one end switch than an “ * ” will be visualized near F1 or near F2.
