DESCRIPTION OF PARAMETER
LANGUAGE
0=ITA/1=ENG/2=FRA/3=ESP/4=TED
DISPLAY BRIGHTNESS ON STANDBY
This parameter allows to enter the brightness setting applied
when the display is set to standby (wait 9 seconds for a preview).
KLIXON SELF-RESET
This parameter defines the automatic or manual reset of the
motor overtemperature alarm from Klixon
PUMP EXPANSION
This parameter defines whether the system provides the card for
the 3rd and 4th pump.
MINIMUM VOLTAGE
Set by default to -10%. (Altering operating limits beyond default
parameters will immediately render the warranty null and void).
MAXIMUM VOLTAGE
Set by default to +10%. (Altering operating limits beyond default
parameters will immediately render the warranty null and void).
MOTOR M1– M4 MAXIMUM CURRENT
This parameter allows the maximum current limit of the motor
to be set.
Enter the maximum current value, increasing it by 10-15% with
respect to the rated motor value.
Altering operating limits beyond the parameters stated on the
model data plate will immediately render the warranty null and
void.
MINIMUM CURRENT OR COS-FI CONTROL ACTIVATION
This parameter allows the dry run control to be enabled by read-
ing the absorbed motor current value or the cos-fi power factor.
MOTOR M1– M4 MINIMUM CURRENT
(If minimum current is enabled)
This parameter allows the MINIMUM motor current to be set
below which the motor must stop due to dry run. By setting the
current to 0, the minimum current dry run control is deactivated.
Enable this parameter only if no floats or probes are in use for
minimum level control.
MINIMUM COS-FI OF MOTOR M1 – M4 (if cos-fi is enabled)
This parameter allows the minimum motor cos-fi to be set below
which the motor must stop due to dry run.
PUMP ROTATION ACTIVATION
This parameter allows the pump changeover to be activated
every time the floats or pressure switches are triggered. In
addition, if the main pump is switched to thermal protection (over-
current), the second pump is enabled (the START/STOP function
is disabled with N).
AUTOMATIC RESET FOR DRY RUN
In the case of a dry run alarm (minimum cos-fi current) the panel
can attempt an automatic reset, programmable in minutes.
Four restart times can be set, whereby the system automatically
restarts after stopping.
AUTOMATIC RESET FOR DRY RUN TIME 1
First attempt to reset the dry run alarm (default: 5 minutes).
AUTOMATIC RESET FOR DRY RUN TIME 2
Second reset attempt counting from the previous reset attempt
(default: 10 minutes).
AUTOMATIC RESET FOR DRY RUN TIME 3
Third reset attempt counting from the previous reset attempt
(default: 20 minutes).
