SIGNALS OF O.R and U.R
The display writes OR (Over Range) when the measure exceeds the maximum measurable.
The display writes U.R (Under Range) when the measure falls below the minimum limit measurable.
The green LED on flashes quickly.
If the pump is in Manual Functioning the dosing is not stopped.
If the pump is in the ON-OFF and Proportional Functioning the dosing is stopped.
pH range: 0-14pH
mV range: 0-1000mV

There are 3 possible functioning:
Function Manual: constant dosing with a number of impulses per minute
programmed as follows in the next paragraph.
Function Prop: dosing proportional to the distance of the measure from the
setpoint. Range of proportionality : 1pH or 100mV
Function On-Off: constant dosing that starts when the measure moves away
from the setpoint. Total Hysteresis centered on the setpoint: 0.1pH or 10mV
Push and quickly release CAL button and scroll the menu using + and – buttons
till the display shows "Function Type". Push CAL to enter the submenu and then
by pressing + and – button choice " Function Manual" and confirm pressing
CAL. The display will show "Freq." and the % stored in the last programming.
Modify it by pressing + and – button and confirm the choice pressing CAL. Push
ESC button to esc the menu and go back in measure with the Manual
functioning just programmed. The number of injections of the pump per minute
depends on the % programmed. For example: 80% means 120 injections per
minute i.e. 150 pulses/min x 0.8 = 120 pulses/min.
In Manual functioning the display shows on the first row "Man." and the %
frequency programmed.
The second row shows the measure.
Push and quickly release CAL button and scroll the menu using + and – buttons till
the display shows "Function Type". Push CAL to enter the submenu and then, by
pressing + and – button, choice "Function On-Off" and confirm pressing CAL.
The display will show the value of setpoint stored in the last programming. Modify it
by pressing + and – button and confirm the choice pressing CAL.
The display will show the direction of dosing Chorination or Dechlorination stored
in the last programming. Choice the direction by + or – button and confirm pressing
CAL.
Select Dechlor if you want the pump to inject for ppM values greater than Setpoint.
Select Chlor if you want the pump to inject for values of ppM lower than Setpoint.
The display will show the % of maximum frequency (150pulses/minute) stored in
the last programming. Modify it by pressing + and – button and confirm the choice
pressing CAL. Push ESC button to esc the menu and go back in measure with the
On-Off functioning just programmed.
In the On-Off functioning if the pump is dosing the display shows "On" and the %
frequency programmed on the first row, if the pump doesn't dose the display shows
"Off" and the % frequency programmed.
On the second row the display writes the measure.
