You can programme relay 1 to be enabled
when the pump starts up or also when an
alarm is triggered in the installation.
N.B. Output 1, when enabled, acts as a
closed contact without voltage.
You can programme relay 2 to be enabled
when the pump starts up or also when an
alarm is triggered in the installation.
N.B. Output 2, when enabled, acts as a
closed contact without voltage.
Notes
You can modify the units to represent the
pressure of the installation.
Enables you to adjust the range of detection
of the transducer if its scale is not the
standard 4-20 mA (0-10 Bar)
Enables you to modify the switching
frequency of the variator, reducing the noise,
although uncommon, of the switching at the
expense of an increase in temperature of the
electronics.
N.B. We do not recommend modifying
the default value except when expressly
indicated by the Technical Department.
Modifies the maximum frequency of pump
operation.
Enables the constant monitoring of the pump
running dry, if this occurs.
Value used in the mathematical algorithm
that calculates the pump running dry.
During the priming time, the detection
of running dry will not be operative even
though the monitoring is enabled.
Enables you to lock the settings of the
variator and the pump so they are not
modified after start-up.
Enables you to reset all the alarms triggered
to date.
N.B.: We do not recommend this reset
because you would lose very important
information that could help solve possible
problems in the installation.
