When this error appears, the electrical system must be controlled by qualified personnel as soon as
possible. The error can only be cleared by disconnecting the device from the electric power supply and
solving the causes of the fault. Attempting to start the inverter when there is an output short circuit may
seriously damage the device and be dangerous for the user.
Auxiliary contact: use this parameter to select the function to be
associated with the auxiliary contact; the values that can be set are the
following:

Dry running: this message appears when the system is stopped
following a pump intake water shortage. If the auto-reset function has
been enabled, the Sirio Entry will automatically make a series of attempts
to test whether the water supply has returned. To clear the error status,

Inverter error: this alarm appears when the inverter is locked following a
power surge or drop outside the limits or overheating with ensuing motor
pump shutdown. Although the system is restored automatically approx. 3
minutes after the error condition has cleared, the message remains on the
screen to warn the user that there might be a failure in the hydraulic and/or
Short Circuit: This message will appear on the screen when there is a
short circuit at the inverter output. the short circuit may be caused by the
incorrect connection of the electric motor, faulty electrical isolation of the
cables that connect the motor pump to the devices or failure of the electric
motor of the pump.
