Not connected cable, broken connection, pressure
transducer spoiled.
Er03 Blockage due to low supply voltage
Supply voltage lower than 190V.
- The system automatically restart when the clamp
voltage is higher than 190V.
Er04 Blockage due to high rectified voltage
Supply voltage higher than 250V.
- The system automatically restart when the clamp
voltage is lower than 250V.
Er05 Blockage due to missed setting of the rated
current or rated frequency
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
Er10 Blockage due to overheating of the power module
Er11 Blockage due to low voltage 24 V
Er12 Stop for float switch intervention
The system will restart after 30 s from the state
variation of the float switch. The control panel
for remote alarm not report this alarm.
Er13 Internal hardware error
Contact the technical assistance
Er14 Cascade mode communication error
Check the RS 485 connection or that both pumps
are enabled.
In case of multiple fault, scroll with the buttons
(plus) or
(minus) to visualize the fault
sequence.
In case of thermal block it is advised to check the causes that have created the problem
