9. DEFECTS - CAUSES - REMEDIES
All incidents hereafter mentioned give rise to :
- The resting of the SBM relay (unavailable transfer).
- The activation of the SSM relay (failure transfer) when the maxi-
mum quantity of one type of defect is reached over a 24 hours
range.
- Lightening of a red LED and the defect code display.
If the defect is major, the action of an after-sales technician is
required.

State of the relay if the number of failure > than the allowed number of failure.
Restart of the pump after a detection of defects :
1st case - The pump has reached the maxi quantity of defects (from 1 to 6, according to the significance) of the same defect type
over a 24 sliding hours period. In this case, the SSM relay is activated and the SBM relay is at rest. The pump can be restarted by pres-
sing on the encoder (long push-on > 2s) or by switching off the supply and by restoring it.
2nd case - The pump hasn't reached the maxi quantity of defects.
In this case, the SSM and SBM relays are at rest. Only a switch off and a restoration of the supply allow the restart.
For both cases, it is necessary to proceed at first to the deletion of the defect. In case of intervention on the pump, switch off the
supply beforehand.

REPAIRING
Prime the pump once again by filling it
(see chapter 8-3)
Density and/or viscosity of the conveyed fluid are
too big. Dismantle the pump and replace the
defective components or clean them
Check voltage at the converter terminals.
Minimum 400V -10%
Check voltage at the converter terminals
Maximum 400V +10%
Check the supply
The pump veers, check the tightness of the non-
return valve
Dismantle the pump, clean it and replace the
defective parts
The motor is foreseen to run at :
maximum water temperature of + 50°C
maximum ambient temperature of + 40°C
Dismantle the motor-converter of the pump, check
it or replace it
Check the connection between motor / converter.
Dismantle the motor-converter, check it or replace it
Dismantle the motor-converter of the pump, check
it or replace it
Check the bypass, check the operating conditions
Check the bypass
The converter is foreseen to run at :
maximum water temperature of + 50°C
maximum ambient temperature of + 40°C
Call on after-sales technician
Check the correct supply and the cable connec-
tion of the sensor
Failure of the interface or the cable. Check or
replace
