7. MAINTENANCE
CAUTION !
Before any operation, switch off the pump(s).
No special maintenance in operation.
Keep the pump and the motor-variator perfectly clean.
In case of prolonged stopping, if there is no risk of frost, it is best not to
drain the pump.
The bearing holding the coupling and the motor bearings are lubri-
cated for their total lifetime and do not require any lubrication.
The mechanical seal does not require any maintenance in opera-
tion. It must never operate dry.

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 pressing on the encoder or by swit-
ching off the supply and by restoring it.

Replacement frequencies
Remark : these are only recommendations, the replacement fre-
quency depends on the operating conditions of the unit , i.e. :
- Temperature, pressure and type of the conveyed fluid for the
mechanical seal.
- Load and ambient temperature for the motor and the other com-
ponents.
- Starting frequency : continuous or intermittent running.

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 maximum
quantity of one type of defect is reached over a 24 hours range.
- ligthening of a red LED and the defect code display.
INCIDENTS
SSM
active Pump is no more primed or runs
1 1 dry.
active Load of the pump is excessive,
1 1
pump is defective, or the pump
is obstructed by particles.
active The variator supply is
1 1
in under-voltage
active
The variator supply is
1 1
in over-voltage.
active A supply phase is missing.
1 1
active The pump is locked.
1 1
active The motor heats.
1 1
Ambient temperature higher than
+50°C.
active The variator or the motor is
1 1
in short-circuit.
active
The thermal sensor of the motor is
1 1
defective or has a wrong connec-
tion.
active The variator heats.
1 1
Ambient temperature higher than
+50°C.
active Internal problem of converter.
1 1
active The cable of the sensor
1 1
(4-20mA) is cut.
• 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 allows 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, swith off the supply
beforehand.
If the defect is major, the action of an after-sales technician is required.

REPAIRING
Prime the pump once again by filling it (see
chapter 6-3).
Check the tightness of the foot valve
Density and/or viscosity of the conveyed fluid
are too big.
Dismantle the pump and replace the defecti-
ve components or clean them.
Check voltage at the variator terminals.
Mini 380V -6%
Check voltage at the variator terminals.
Maxi 440V +6%
Check the supply.
Dismantle the pump, clean it and replace the
defective parts. It may be a mechanical failure
of the motor (bearings).
Clean the cooling ribs of the motor.
The motor is foreseen to run at an ambient
temperature of +50°C.
Dismantle the motor-variator of the pump,
check it or replace it.
Dismantle the motor-variator of the pump,
check it or replace it.
Clean the cooling ribs rearside and under the
variator as well as the fan cover.
The variator is foreseen to run at a maximum
ambient temperature of +50°C.
Call on after-sales technician.
Check the correct supply and the cable
connection of the sensor.
If the failure is suppressed.
