9. Defects - causes - remedies
All incidents hereafter mentioned give rise to :
• The resting of the SBM relay (unavailable trans-
fer)
• The activation of the SSM relay (failure transfer)
when the maximum quantity of one type of
defect is reached over a 24 hours range.
• Lightening of a red LED and the defect code dis-
play.
If the defect is major, the action of an
after-sales technician is required.

Restart of the pump after a detection of defects :
1st case - T T h h e e p p u u m m p p h h a a s s r r e e a a c c h h e e d d t t h h e e m m a a x x i i q q u u a a n n t t i i t t y y o o f f d d e e f f e e c c t t s s (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 pressing on the encoder (long push-on > 2s) or by switching off the supply and by restoring it.
2nd case - • T T h h e e p p u u m m p p h h a a s s n n ' ' t t r r e e a a c c h h e e d d t t h h e e m m a a x x i i q q u u a a n n t t i i t t y y o o f f d d e e f f e e c c t t s s . .
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.
