To comply with the standards of
electromagnetic compatibility, for
cable length greater than 1 meter, it is
recommended the use of a shielded cable
with protection sheath connected on the
ground on each frequency converter.
7.5. Cascade mode with 1 variable speed
pump and 5 xed speed pumps.
Connect the clamps with contactors according to
the diagram shown at paragraph 20.6., and connect
the motor cable and the power supply cable of the
related xed speed pump to the contactor.
Relay D2 e D3 max 400 VAC/VDC maximum
current 0,5 A at 25°C and 0,2 A at 85°C.
Relay D4 – D6 max 250VDC o 30VDC cmaximum
current 1 A.
The connection with the power supply must
be made with installation of a tripolar circuit
breaker of proper size.

8.1. Parameters
On the frequency converter the following
information is displayed:
Parameters of pump status
Programming parameters
Alarms
8.2. Parameter of pump status
They allow to visualize:
Working frequency of the pump
The measure of the transducer (in case of
differential mode the measure is referred to the
difference between the 2 transducers).
The current absorption.
Starting from the basic display by pushing of the
directional arrow
(plus) or (minus).
Example:
8.3. Programming parameters
To show the programming parameters, select
(menu).
In orded to change the parameters AP, SA, PC, PP,
tC, CF, MAN, the frequency converter should be in
the “oFF” state on display.
Will be displayed progressively:
UP – User settings: these are the basis settings
that the user may change.
AP – Advanced settings: these settings are
available only to qualied personnel. To enter
password is required (see section 8.5).
SA – Technical assistance settings: these
are the advanced parameters, only technical
assistance personnel are allowed to access this
menu. Password is required (see section 8.5).
PC – Constant pressure mode settings
These settings regulate the constant pressure
mode. A password is required to set these
parameters.
PP – Proportional pressure mode settings
These settings regulate the proportional pressure
mode. A password is required to set these
parameters.
tC – Constant temperature mode settings
These settings regulate the constant temperature
mode. A password is required to set these
parameters.
CF – Constant ow mode settings
These settings regulate the constant ow mode. A
password is required to set these parameters.
MAn – Fixed speed mode settings
These parameters allow activation of the xed
speed mode and the working frequency. Only
qualied personnel are allowed to access this
menu. Password is required.
AE – Advanced parameter: this allows for the
display of secondary parameters which can be
useful for system diagnostics.

By pushing the
button (menu) the UP parameter
appears. Select the AE parameter by pushing the
(plus) up to arrive at the correct parameter
AE, conrm with (enter). Select the parameter
AE02 by pushing the button (plus) and conrm
with (enter). Supply voltage is displayed.
