7.5.
Cascade mode with 1 variable speed
pump and 5 fixed 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 fixed 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).

8.3. Programming parameters
To show the programming parameters, select
(menu).
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 qualified 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 flow mode settings
These settings regulate the constant flow mode. A
password is required to set these parameters.
MAn – Fixed speed mode settings
These parameters allow activation of the fixed
speed mode and the working frequency. Only
qualified 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.
