Manual Mode
In Manual mode the pumps may be started and stopped with the P1/ON-OFF, P2/ON-OFF, P3/ON-
OFF keys and there is no pressure regulation.
The controls for minimum pressure switch, minimum level alarm, maximum pressure threshold alarm,
minimum pressure threshold alarm, alarm block from outside, are deactivated.
Automatic Mode
In automatic mode the pumps are controlled by the SM30 BSETF3 board according to the demand
received from the pressure sensor or from the pressure switch consent, to keep the pressure at the
desired level.
In order to operate correctly, the board must be programmed with the system parameters.
Whenever the board is switched on, the default mode is automatic.
Programming
The board is programmed by modifying the parameters in two menus, the Parameters Menu and the
Service Menu.
A third menu allows the display of the alarms that have occurred. The Alarms Log menu is accessible
in both automatic and manual mode.
Parameters menu
The SM30 BSETF3 electronic board is supplied already programmed, however it may be
necessary to modify some parameters for better operation. The Parameters programming
menu contains the system parameters (number of pumps, presence of jockey pump, choice
between system with pressure sensor and system with pressure switches, default, complete list
see chapter 6).
Service menu
In this menu it is possible to change the language and enable changing of the following
parameters in automatic operation: pump START/STOP working thresholds, probe sensitivity,
timing, compensation of leaks.
