6.3.2
Setting the radiation output in operating mode "control off"
The output of new lamps and lamps in systems with a flow that is less than the maximum can
be reduced in order to prolong their operating life and conserve electrical energy.
If, during operation, the UV output of the lamp falls and the UV sensor signal reaches or falls
below the warning threshold, the lamp output should be increased gradually to the maximum
level.
A slight difference between the preset value and actual lamp output is normal.
NOTE
When setting the lamp output, ensure that the corresponding sensor signal is well
above the warning threshold in order to avoid triggering warning messages and system
faults.
Use the CHANGE key to locate the LAMP PERFORMANCE display.
Press the ENTER key to confirm and ACCESS CODE REQUEST will be displayed.
Enter the access code and confirm it by pressing the ENTER key. LAMP PERFORMANCE
will reappear and the values that can be adjusted will flash.
Use the UP and DOWN keys to set the required lamp output.
Press the ENTER key to confirm this and the message "Data is being saved" will appear
briefly.
Press the RETURN key twice to return to the normal display.
Wait for approximately 1 minute until the required UV sensor signal is set. If necessary,
change the lamp output slightly.
6.3.3
Setting the radiation output in operating mode "control on"
In the operating mode "control on" there are two control options for the radiation output:
•
the operating mode "manual control" is used where there is a reduced radiation output to
automatically compensate for the e.g. loss of UV output caused by weathering of the
radiator.
•
with the operating mode "external control", the radiation output is also regulated by an
external command signal (e.g. signal from a flow meter).
NOTE
•
Calibration of the sensor (s.6.3.1) should only be done with new radiators and at full
radiation capacity.
•
Radiation should not fall below the minimum radiation output setting of 20 %.
•
The following instructions assume that the water has a virtually constant UV
transmission. Special settings for water with a fluctuating UV transmission are
available on request.
6.3.3.1 Setting the radiation output in operating mode "control manual"
Press the CHANGE button to go to the CONTROL display.
Confirm by pressing ENTER, REQUEST RELEASE CODE appears.
Enter the release code and confirm by pressing ENTER; CONTROL re-appears; the setting
to be adjusted now flashes.
Use the UP or DOWN button to set to OFF and confirm by pressing ENTER. The message
appears "Data has been saved".
Set the radiation output in accordance with 6.3.2 to the maximum possible value.
Calibrate the sensor in accordance with 6.3.1.
Use the STOP/START button to switch to SYSTEM OFF.
Press the CHANGE button to go to the CONTROL display.
Confirm by pressing ENTER, REQUEST RELEASE CODE appears.
Enter the release code and confirm by pressing ENTER; CONTROL re-appears; the setting
to be adjusted now flashes.
