A6 EXCESSIVE TEMP
Final failure
The system has a cooling device to keep the
INVERTER
in optimum working
condition.
If an excessive temperature is reached the own system leaves the inverter out of
service and as consequence the pump too.
Verify the temperature of the water, it should be under 40 ºC and the temperature
environment should be under 50 ºC.
Contact Stuart Turner technical services.
A7 SHORTCIRCUIT
Final failure
The iMatic has an electronic system for protection against short circuits as well as
a fuse of 20 A.
The pump remains stopped for 10". Then it starts again - 4 attempts. If the
problem is not solved, the pump will remain definitively out of order.
Check the pump, if the problem persists, contact Stuart Turner technical services.
A8 OVERVOLTAGE
Failure verification
The iMATIC has an electronic safety system against overvoltages.
IIn case of overvoltage the system remains stopped until an adequate value of
voltage is reached. In this case, the system is automatically restored.
Check the electric supply.
A9 UNDERVOLTAGE
Failure verification
The SPEEDMATIC has an electronic safety system against too low supply voltages.
In case of undervoltage the system remains stopped until an adequate value of
voltage is reached. In this case, the system is automatically restored.
Check the electric supply.

Check the electric supply 230 V. In case of being in right conditions, the general
fuse (20 A), located in the main plate (fig 3) should be verified.
