Paragraph 3 – Proportional dosing for the Redox (O.R.P.) measurement
The pump measures and controls the Redox value of a solution, by
programming the following parameters: set-point, set-point type,
proportional band and alarm band.
Set-point type: maximum

Can also be programmed:
- The O.F.A. (Over Feed Alarm) time in minutes, a set period of time after
which, if the measured Redox value does not reach the set-point, an
alarm signal is activated.
- Activation / deactivation of the calibration procedure
Allarmi e stati
• Cal = calibrazione non
eseguita
• Liv = Allarme livello
• Fls = Allarme flusso

• OFA = Allarme O.F.A.
Valore misura del
potenziale Redox.
Stato della pompa
• Vuoto = pompa in start
• Stop = pompa ferma
• Paus = pompa in pausa
Valore del dosaggio in corso
(dipende dall’unità di misura
selezionata)
