The pH pump is switched off.
The set point is active however the pump is temporarily
switched off
The set point is active and the pump is switched on.
During programming, it indicates that the parameter being
displayed refers to control of the pH set point.
The chlorine pump is switched off.
The set point is active however the pump is temporarily
switched off
The set point is active and the pump is on.
In the programming phase, this indicates that the
parameter being displayed refers to control of the Chlorine
set-point.
An alarm status has occurred and the alarm relay is active.
To reset the alarm press the ACK key.
An alarm has been acknowledged by pressing the ACK
key, however the cause leading to the alarm is still
present. The alarm LED will extinguish once the cause of
the alarm has been eliminated.
The instrument prompts you to dip the electrode into a
standard solution having a pH of 7. It is therefore ready to
carry out calibration of the offset on the pH electrode
The instrument prompts you to dip the electrode into a
standard solution having a pH of 4. It is therefore ready to
carry out calibration of the gain on the pH electrode
The instrument is ready to carry out self-calibration of the
chlorine measurement. It is waiting for the chlorine value
measured by means of the DPD method to be entered.
