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
b and - simultaneously. If the error condition persists, the cause of the fault must be located and
eliminated.

Table 29: Block information
7.1 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.
