Displayed alarm
Er01 Blockage due to no water
Er02 Pressure transducer fault
Er03 Blockage due to low supply voltage
Er04 Blockage due to high rectified voltage
Er05 Blockage for memory failure
Er06 Blockage due to overcurrent in the electro
pump motor
Er07 Blockage due to overcurrent in the
frequency converter
Er08 Blockage due to direct short circuit between
the phases of output terminals
Er09 Blockage due to overheating

In case of multiple fault, scroll with the buttons
In case of thermal block it is advised to check the causes that have created the problem before
restart the pump operation.

Causes
The device is in failure due to no water.
The system try to restart automatically.
- One attempt every 10 minutes for 6 times.
- One attempt every hour for 24 times.
- One attempt every 24hours for 30 times.
Not connected cable, broken connection, pressure
transducer spoiled.
Supply voltage lower than 190V.
- The system automatically restart when the clamp
voltage is higher than 190V.
Supply voltage higher than 250V.
- The system automatically restart when the clamp
voltage is lower than 250V.
The system will restart with a delay defined by AP19
from the state variation of the float switch. The control
panel for remote alarm not report this alarm.

Check the RS 485 connection or that both pumps
are enabled.
