4.3 LEVEL ALARM (only for the model with the level probe)
A level probe can be connected to the pump to report the end of the product, which is indicated by the pump in the
following way:

Audio signal via the buzzer (if there is one on the pump) and if enabled (see A.bu on t
he “Settings Menu”)
with a frequency of 1 second on and 1 second off;

flashing red LED;
 “
uLo
” flashing on the display;
The inlet has a 3-second recognition filter to identify false contacts and unwanted level alarm signals.
This alarm may or may not impl
y the pump will stop, depending on the option chosen in the “
St.P
” submenu
(Settings Menu: St.P =SI

the pump is stopped; St.P =no

the pump keeps on dosing).
The alarm is automatically reset when the level of the chemical product to be dosed is restored.
In priming mode, the level alarm is not indicated.
4.4 OFF STATUS ALARM
If the switch is left on the OFF position, after 20 minutes the switch alarm is activated and signalled by the pump in
the following way:

Audio signal via the buzzer (if there is one on the pump) and if enabled (see A.bu
on the “Settings Menu”)
with a frequency of 1 second on and 1 second off;

flashing red LED;
 “
OFF
” flashing on the display;
Just set the switch to ON to disable it.
4.5 OFA ALARM
The OFA alarm is a dosing alarm and is distinguished in two distinct signalling phases: OFA 1 Alarm and OFA 2
Alarm.
The OFA 1 alarm is activated when the set conductivity set-point is reached within an established time-frame
(
T
OFA
).
The observation time may be set from 1 to 999 seconds or may be disabled (OFF) from the entry OFA of the Menu
Settings: counting of
T
OFA
is activated at the beginning of the pump dosing.
The OFA 2 alarm is the second level of signalling of the said alarm, which is activated after a set-point situation is
not reached and remains for double the set time, therefore, after [2 x (
T
OFA
)] seconds from the beginning of dosing.
The OFA alarm is reported by the pump in the following way:

Audio signal via the buzzer (if there is one on the pump) and if enabled (see A.bu
on the “Settings Menu”)
with a frequency of 1 second on and 1 second off;

flashing red LED;
 flashing “
OF1
” or “
OF2
” on the display;

OFA 1 Alarm: the pump continues to dose;

OFA 2 Alarm: Stop dosing;
The OFA 1 alarm will be disabled if:

The conductivity value is brought back to the Set-point value;

Use the switch or the pump power supply to turn it on or off;
The OFA 2 alarm will be disabled if:

Turning off and turning on is carried out through the switch or by means of the pump power supply, if the OFA
alarm Reset setting, OF.r , is equal to Aut ;

Turning off and turning on is only carried out by means of the switch, if the OFA alarm Reset setting, OF.r , is
equal to OFF ;
