7. PROTECTION SYSTEMS
The inverter is equipped with protection systems designed to preserve the pump, motor, power line and the inverter itself. When one
or more protections trip, the one with the highest priority is shown on display. Depending on the type of error, the electric pump may
shut down, but when normal conditions are restored, the error state may clear automatically, immediately or after a set time interval
following automatic reset.
In the case of a block due to water supply failure (BL), block due to pump motor current overload (OC), block due to final output stage
current overload (OF), block due to direct short circuit between the phases on the output terminal (SC), the user can attempt to manually
reset the error condition by pressing and releasing buttons + and - simultaneously. If the error condition persists, the cause of the fault
must be located and eliminated.

Description of blocks
7.1.1
"BL" Block due to water failure
In flow conditions below minimum value, with pressure lower than the set regulation value, a water failure signal is emitted and the
system shuts down the pump. The delay interval without pressure and flow can be set in the parameter TB of the TECHNICAL
ASSISTANCE menu.
If the user inadvertently enters a pressure setpoint higher than the pressure that the electric pump can supply on closure, the system
indicates "block due to water failure" (BL) even if this is not precisely the problem. In this case, lower the regulation pressure to a
reasonable value, which does not normally exceed 2/3 of the head of the electrical pump installed.
The parameters SO: Dry running factor 6.5.14 and Minimum pressure pump stop due to water failure 6.5.15 enable the user to enter
the dry running protection activation thresholds.
If the parameters: SP, RC, SO and MP are not set correctly, the water failure protection will not function correctly.
7.1.2 "BPx" Block due to fault on pressure sensor
If the inverter detects a fault on the pressure sensor, the pump remains blocked and the error signal "BPx" is displayed. This status
starts as soon as the problem is detected and is reset automatically when the correct conditions are restored.
Irregular shutdown
