A2 OVER-INTENSITY
Failure verification
Final failure
The system pumps are protected against over currents by mean of the intensity
values established in the installation menu. These over currents are produced
generally by dysfunctions in the pump or in the electric supply.
When detecting the thermal failure, the pump will be automatically stopped. The
system will try again to restart the pump when the demand of consumption
require it. The control system will carry out 4 attempts in this circumstances. If the
system remain locked after the 4th attempt, the pump will remain definitively out
of order.
Verify the state of the pump, for example the impeller could be blocked. Verify
intensity values introduced in the configuration menu. Once the problem have
been solved the operation will be restored going to the “SET UP” menu ( see the
chapter configuration) and configuring the adequated intensity values.
A3 DISCONNECTED P.
Final failure
The iMATIC has an electronic safety system against short circuits as well as a 20 A
fuse.
The device is disconnected.
The wound of the motor and the pump consumption should be verified. Once the
problem has been solved the operation will be restored going to the "SET UP"
menu (see the chapter configuration) and introducing the adequate intensity
values. Verify the 20 A fuses (see Fig.3).
A5 TRANSDUCER
Final failure
The transducer damages are showed in the iMATIC LCD screen.
The device operation is interrupted.
