LEVEL CONTROL
The closing of the level input contact, free of tension, will cause:
1) the dosage stops (if level probe is on Rx in DUAL pH/REG system, the plug activity stops)
2) the green ON led blinks
3) the display shows "Lev" alternatively on the second line and the actual measure.
Here above there is the example of level alarm on pH pump. When the level contact gets opened again, the pump returns
to working mode compatible with the actual inputs.
NOTE: The level alarm suspends (but not reset) the counting of the Alarm Time.
FLOW CONTROL
The closing of the flow input contact, free of tension, will cause:
1) the dosage stops (and the activity of the Rx plug stops in DUAL pH/Reg system)
2) the green ON led blinks
3) The display shows "Flow" alternatively on the second line and the actual measure.
When the flow contact gets opened again, DUAL returns to working mode compatible with the actual
inputs. NOTE: The flow alarm resets the counting of the Alarm Time.
SIGNALS OF O.R and U.R:
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 system is in Manual Functioning the dosage is not stopped. If the system is in the
ON-OFF or Proportional Functioning the dosing is stopped. pH range: 0-14pH. mV range: 0-1000mV
OUTPUT FOR ALARM (RELAY 'N.O) :
alarm (flow, level, Tal, OR and UR) and opens when Dual leaves the alarm state (refer to connection I in CONNECTIONS
figure on page 11)
OPERATION PROGRAMMING AND CALIBRATIONS:
CAL) for more than 60 seconds, DUAL will leave the programming keeping the data stored until that moment. !!! After
setting the desidered Operation Programming push ESC to go back in working mode.
Choose whether you want to program or calibrate the pH or the Rx as shown in the figures above

The display writes OR (Over Range) when the measure exceeds the maximum
The optional output for the alarms is a contact that closes when Dual is in
