INNER TEMPERATURE
The inner temperature is monitored at all times.
If the temperature goes above 85°C the unit stops.
The reset is automatic when the normal temperature is reinstated.
UNIT STOP DUE TO OPENING OF AUXILIARY INPUT
This occurs when a switch is installed at the auxiliary input (for example, a float
sensor in the intake tank), and the contact of the switch opens.
It automatically resets when the contact closes again (for example, when the
water level is restored).
VOLTAGE
The input voltage of the system will be monitored constantly.
The system will stop if the +20% (Max)/-20% (Min) limits are exceeded.
The reset is automatic when the nominal voltage is reinstated.
PRESSURE TRANSDUCER
The pressure transducer connected to the unit is not working properly
The system will stop.
(For booster sets, if other transducers are connected to Speedrive slaves, the
booster will not stop and automatically switch to another transducer)
DRY RUNNING
If a pump runs for more than 10 seconds without water, the unit stops.
The reset is automatic. If the error is not solved 4 new attempts* are performed.
If the error is still present after the fourth attempt, the system will be set to a
permanent fault.
Before resetting, ensure that the pump is correctly primed again.
Press OK to reset. The start screen (#2) will appear.
ELECTRONIC CIRCUIT FAILURE
The electronic circuit is breakdown.
The Speedrive stops working. It can only be repaired by official technical service.
ERROR IN READING PARAMETERS
When reloading new software, an error occurred in the reading of internal
parameters.
Restart the unit by disconnecting and reconnecting the power supply.
LOW VOLTAGE IN THE MODULE
The power module protects itself against internal voltage drops.
FAILURE IN THE INTERNAL VOLTAGE OF THE ELECTRONIC CIRCUIT
The electronic circuit has suffered a serious malfunction.
The Speedrive stops working. It can only be repaired by an official technical
service.
ERROR DUE TO EARTH LEAKAGE IN THE ENGINE
Earth leakage has been detected in one of the engine phases.
The unit stops.
Before resetting, make sure that the engine malfunction has been repaired.
Press OK to reset. The start screen will be displayed (no. 2).
