In order for the guarantee to remain valid, the alarm log and all counters (operating hours, number of starts, etc.) can only be reset at the
manufacturer's premises, where the memory is completely deleted.
DESCRIPTION
E0
Low voltage: indicates that the power supply voltage is too low. Check the input voltage
value.
E1
High voltage: indicates that the power supply voltage is too high. Check the input voltage
value.
E2 - Short Circuit: This message will appear on the screen when a short circuit is detected at
the inverter output. This may occur following incorrect connections of the electric motor,
damage to the electrical insulation in the wires connecting the electric pump to the device or a
fault in the pump's electric motor. When this error appears the electrical system should be
checked as soon as possible by specialised personnel. The error may only be removed by
disconnecting the equipment from the electrical power source and resolving the cause of the
fault. Attempting to restart the inverter in the presence of a short-circuit on output may cause
serious damage to the equipment and be a source of danger to the user.
E3 - Dry-run: this message appears when the system is stopped following a pump intake water
shortage. If the auto-reset function is enabled, Sirio will carry out automatic attempts to check
for the availability of water. To clear the error status, press the central "reset" button.
E4-Ambient temperature: this error appears if the maximum internal ambient temperature of
the inverter is exceeded. Check the conditions of inverter operation.
E5-IGBT module temperature: this error appears if the maximum temperature of the IGBT
module of the inverter is exceeded. Check inverter operating conditions, in particular the water
temperature and current absorbed by the pump.
E6-Overload: this alarm is displayed when electric pump absorption exceeds the maximum
set current as entered in the Imax value: this may occur following intensive use of the electric
pump, continuous restarts at close intervals, problems with the motor windings, or following
problems with the electrical connection between the motor and Sirio. If this alarm trips
frequently, arrange for the system to be checked by the installer.
E8-serial error: this alarm may occur where there is an internal serial communication on Sirio.
Contact the technical assistance.
E9-Pressure limit: the alarm intervenes when the maximum set pressure threshold has been
exceeded. If the error appears repeatedly, check the setting of the "P limit" parameter. Also
check other conditions which may have caused an overpressure (for example, partial freezing
of the fluid).
E10-External error: this alarm will be displayed if, after setting the external error function
on the auxiliary I/O board, the I/O input contact is closed.
E11-Number of maximum starts/hour: this error appears if the maximum number of
admissible start-ups per hour has been exceeded. Check for the presence of any leaks in the
system. Check the pre-loading of any installed tanks.
E12-Error 12V: an anomaly has been detected in the internal low voltage power supply circuit.
Have the manufacturer check the device.
E13-Pressure sensor error: the pressure sensor has detected an incorrect value. Have the
manufacturer check the device.
