pump operation, this feature can be disabled. Before disabling, though, ensure it will not cause
damage to the pump or system (see section titled "DESCRIPTION OF THE PARAMETERS
AND THE SCREEN PAGES").
there might be a failure in the hydraulic and/or electric system. Every time this alarm appears, it
is advisable to have the system checked by skilled personnel to prevent electrical damage. To
clear the message from the display, simply press the "reset" button in the centre.
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:
"1 <->" to use the auxiliary contact to connect two Sirio Entry
devices as part of a twin pressurisation unit (manufacturer's default
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, press the "reset" button in the centre.
Serious leakage: this message appears when the pump has been
stopped following a closely spaced series of restarts caused by a
possible leak in the system. To restore the system status once the
cause of the alarm has been established, press the "reset" button in
the centre. If this condition occurs repeatedly, impairing normal
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
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.
