(i.e. broken pipe, open pressure relief valve,
etc.)
Check the min alarm value setting.
IGBT TRIP ALARM
The current drawn by the load exceeds the
capacity of DrivE-Tech.
DrivE-Tech is still able to continue to power
the load for 10 minutes with an output
current of 101% of nominal and for 1
minute with an output current of 110% of
nominal
Increase the ramp-up time
Make sure that the load current is at least
10% below the DrivE-Tech nominal current
Check the voltage drop along the supply
cable to the motor
NO
COMMUNICATION
Communication between Master and
slave(s) has been interrupted
Check the wiring connections
Make sure the Master is not in the Menu
level; if so, exit from the level.
In the STATUS of the slave (where the alarm
is displayed) try to reset the alarm by
pushing STOP button.
ADDRESS ERROR
Same address as other DrivE-Techs in the
group
The address of each DrivE-Tech needs to be
different
KEYBOARD FAULT
A Button on the keyboard has been pressed
for more than 150 seconds
Make sure buttons are not depressed

If pumps cosphi is lower than the dry-running cosphi for at least 2 seconds, DrivE-Tech will stop
the pump. DrivE-Tech will try to run the pump every 10, 20, 40, 80, 160 minutes and then the
pump is stopped.
ATTENTION: if dry-running protection occurs, DrivE-Tech will try to start the pump
automatically. Be sure to cut power supply before attempting maintenance
DrivE-Tech will stop the pump if the input motor current is higher than the set motor current for
an extended time. By pressing the START button it is possible to run the pump again.
DrivE-Tech will stop the pump if the input voltage is higher than the set voltage for an extended
time. By pressing the START button it is possible to run the pump again. DrivE-Tech will stop the
pump if the input voltage is lower than the set voltage for an extended time. By pressing the
START button it is possible to run the pump again.
8. Auxiliary pumps during constant pressure control
When the water needs vary considerably, it is advisable to share the water request between several pumps ensuring better
efficiency and reliability.
A first method consists of a single pump driven directly by DrivE-Tech and another 1 or 2 pumps directly connected to the
mains DOL (Direct On Line); DOL pumps are controlled by DrivE-Tech and connected to the mains through 1 or 2 contactors.
