VISUALIZATIONS
During normal operations, the display shows the two measured values on the top line, while the bottom
row displays the status of the two pumps.
For example:
“7.25pH 286mV”
“P1 ON P2 020%”
(pump 1 ON in ON/OFF mode, pump 2 ON in proportional mode with indication
of the functioning percentage)
In these conditions, pressing the
or
button, you can display the OFFSET and GAIN values of the
pH and redox measurements. For example:
“7.25pH”
“O=-4 G=1.000”
This information is useful to verify the electrode status. Note that an electrode in good condition should
have an offset close to zero and a gain close to 1.000. When these values deviate from the ideal ones,
indicate a dead electrode or sensor aging.
During manual working mode, the display shows on the top line the pump to which the information
refers, while the bottom row shows the pump status.
For example:
“Pump 2 manual”
“ON ”
In these conditions, pressing the ON/OFF button allows to enable / disable the pump. In case of fault
or alarm condition, the pump stops dosing until the normal working conditions are restored.
OPERATION OF THE ELECTRONIC UNIT
To access the configuration, calibration and manual mode menus, press the CAL button. The display
will show the following available options:
•
Standard Configuration
•
Advanced Configuration
•
Calibration IN1 (input 1) pH
•
Calibration IN2 (input 2) redox
•
Manual Mode 1 (pump 1, acid dosage)
•
Manual Mode 2 (pump 2, chlorine dosage)
Use the
keys to scroll the available options, then press CAL to enter the highlighted mode or ESC
to return to measurement visualization.
Standard Configuration
The standard configuration mode allows the customer to set a series of parameters related to the normal
functioning of the unit. These parameter can be freely accessed and configured from the front keyboard.
1) Once selected the “Standard Configuration”
option, press the CAL button to edit the list of
parameters, or press ESC to return to the
normal visualization mode
2) Now use the
keys to scroll the list of the
available parameters
3) To modify the displayed parameter, press CAL; to quit the mode press ESC
