NOTE: In general, any time the user accesses the menu screen of the master DrivE-Tech,
the DrivE-Tech communication with slaves is automatically terminated.
To operate the unit, simply press the green button (START) DrivE-Tech 's only master.
Each DrivE-Tech slaves can be arrested regardlessly in case of need by acting on the
corresponding red button, compatibly with the water demand of the system and the
possibility of being replaced by an additional device. If you wish to exclude a security from
DrivE-Tech combined operation is necessary to disconnect the corresponding sensor, in
order to prevent the DrivE-Tech master commands automatically START the slave of
interest. In case of alarm or failure of a pump this will be replaced (temporarily
or
permanently depending on the type of alarm that occurred) by a 'of the other group. to
allow replacement of the master of communication is necessary that the slave replacement
candidates have set the function ON AUTOMATIC START (advanced parameters). Member
is replaced by priority of address (1 to 7).

FOR THE SETTINGS OF DRIVE-TECH REFER TO DOCUMENTATION ATTACHED.
Before starting up, please read carefully this Manual and the instructions of inverter (DRIVE-TECH). In this way
incorrect settings and manouvres are prevented, which could cause functioning anomalies. The system must
never be started dry for any reason. Dry running of the pumps, even for very brief periods, can cause
irreversible damage to mechanical sealing and internal rotating couplings. Priming must be performed before
system start-up. Whenever the equipment is powered by the mains (upon initial installation, following voluntary
shutdown or in the event of a power cut and the subsequent return of power), it will enter a start phase lasting
about few seconds. Because all of the operating parameters - including its alarm/ blocking conditions - are
stored on a non-volatile memory, the inverter (DRIVE-TECH) will resume the same operating conditions as
when it was last shut-down (including in the event of accidental power supply failure) start phase. Where the
DRIVE-TECH was ON when the last shut-down occurred, the pump will activate if the pressure detected is less
than the predetermined threshold; you can put the group OUT OF SERVICE prior to the automatic start-up by
hitting “0” STOP. Where the inverter (DRIVE-TECH) was OFF when the last shut-down occurred, the group will
remain OUT OF SERVICE start phase. To start-up, hit “I” START and confirm. In applications with parallel
inverters, each inverter monitors and protects the pump to which it is connected, and the work is distributed
among the various pumps in the group on the basis of actual hours worked by each pump. In case of failure of
a unit of the group, the remaining pumps continue to operate.
Priming
A pumping system must never be started dry for any reason. Dry running of the pumps, even for very brief
periods, can cause irreversible damage to mechanical sealing and internal rotating couplings. All pumps must
be primed before starting the system by unscrewing the filler cap and filling the pump body with water (and the
intake piping connected to it). When the operation has been completed, tighten the cap and start the pump,
with the cut-off valve in flow almost completely closed.
If, after a few tens of seconds, the pump is not primed, switch it off, check that the intake is free, that there are
no air pockets upstream from the inlet, that the body is full of water and then repeat the operation.
9. RUN COMMISSIONING
Before removing the inverter (DrivE-Tech) cover or starting interventions on it, the system
must be disconnected from the mains electricity and you must wait 5 mins until the
intermediate circuit condensers, which can reach voltages up to 800V, have the time to
discharge via the built-in discharge resistors.
