DAB e.sybox Instrucciones Para La Instalación Y El Mantenimiento página 103

The pumps must all be connected to a single delivery manifold:
For good operation of the pressure boosting set, the following
must be the same for each device:
• hydraulic connections
• maximum speed (parameter RM)
The firmware of the connected e.sybox units must all be the same. Once
the hydraulic system has been made, it is necessary to create the pumping
set by carrying out the wireless association of the devices (see par 7.5.5.)
9.4.3 - Wireless communication
The devices communicate with each other and send the flow and pressure
signals by wireless communication.
9.4.4 - Connection and setting of the inputs
The inputs of the I/O control unit are used to activate the float, auxiliary set-
point, system disabling and low suction pressure functions. The functions
are indicated respectively by the float switch (F1), Px, F3 and F4 symbols.
If activated, the Paux function boosts the pressure in the system to the
set pressure see par. 7.6.15.3 - Setting auxiliary setpoint input function.
The functions F1, F3, F4 stop the pump for 3 different reasons, see par
7.6.15.2, 7.6.15.4, 7.6.15.5.
The parameters for setting the inputs I1, I2, I3, I4 are part of the sensitive
parameters, so setting one of these on any device means that they are
automatically aligned on all the devices.
Parameters linked to multipump operation
The parameters shown on the menu for multipump operation are classified
as follows:
• Read-only parameters.
• Parameters with local significance.
• Multipump system configuration parameters
which in turn are divided into:
• Sensitive parameters
• Parameters with optional alignment
9.4.5 Parameters concerning multipump
Parameters with local significance
These are parameters that can be divided among the various devices and
in some cases it is necessary for them to be different. For these param-
eters it is not allowed to align the configuration automatically among the
various devices. For example, in the case of manual assignment of the
addresses, these must absolutely be different one from the other.
List of parameters with local significance for the device:
• CT Contrast
• BK Brightness
• TK Backlight switch-on time
• RI Revs/min in manual mode
• AD Address Configuration
• IC Reserve configuration
• RF Reset fault and warning
• PW Set Password
Sensitive parameters
These are parameters which must necessarily be aligned over the whole
chain for adjustment reasons.
List of sensitive parameters:
• SP Setpoint pressure
• P1 Auxiliary setpoint input 1
• P2 Auxiliary setpoint input 2
• P3 Auxiliary setpoint input 3
• P4 Auxiliary setpoint input 4
• RP Pressure decrease to restart
• ET Exchange time
• AY Anticycling
• NA Number of active devices
• NC Number of simultaneous devices
• TB Dry run time
• T1 Switch-off time after low pressure signal
• T2 Switch-off time
