Hydraulic Connections; Risk Of Frost; Characteristics - Interpretations - Operation - DAB ACTIVE DRIVER M/M 1.1 Instructions Pour L'installation Et La Maintenance

6.6 To protect the system it is recommended to install a differential switch with correct
dimensions, type: Class A, with adjustable dispersion current, selective, protected against
sudden tripping. The automatic differential switch must be marked with the following
two symbols:

HYDRAULIC CONNECTIONS

Always install a check valve on the pipe upstream from the ACTIVE DRIVER.
7.1
For the purposes of operation of the ACTIVE DRIVER it does not matter whether the valve is fitted on the
suction or on the delivery of the pump.
The hydraulic connection between the ACTIVE DRIVER and the electropump must not have any
7.2
derivations.The dimensions of the pipe must be suitable for the electropump installed.
The ACTIVE DRIVER works at constant pressure. This regulation is appreciated if the hydraulic
7.3
system downstream from the system is of suitable dimensions. Systems made with pipes that have
too narrow a section introduce load losses which the appliance cannot compensate; the result is that
the pressure is constant on the device but not on the user.
RISK OF FROST: pay attention to the place where the ACTIVE DRIVER is installed!
7.4
If the place of installation reaches a temperature below 0°C, the following precautions must be
taken:

If the ACTIVE DRIVER is operative it is absolutely necessary to protect it suitably against
frost and to leave it constantly fed.
If it is disconnected from the power supply, the anti-frost function is no longer active!

If the ACTIVE DRIVER is not operative it is advisable to turn off the power supply,
disconnect the appliance from the pipe and completely empty out all water left inside it.
It is not sufficient just to remove pressure from the pipe, because some water is always left inside.
8. CHARACTERISTICS – INTERPRETATIONS – OPERATION
The ACTIVE DRIVER is an innovative integrated system for controlling electropumps with variable speed,
able to keep a constant pressure while the flow rate varies. The ACTIVE DRIVER is composed of an inverter,
a pressure sensor and a flow sensor. With the exclusion of models M/M 1.1 and M/T 1.0 the ACTIVE
DRIVER is provided with 3 inputs and 2 outputs so as to be able to realise certain interface solutions with
more complex installations.
Figure 1 shows the logical function diagram for the connection of the user input terminals.
Figure 2 shows the logical function diagram for the connection of the alarm output terminals.
Figure 3 shows the connection diagram for 2 ACTIVE DRIVER units, for the exchange function .
