• In case of failure, do the filling in again and start
the operation again.
• Check that the current input does not exceed
the value indicated on the motor-converter data
plate.
7. Maintenance
DANGER! Before working on equipment, switch
it off and prevent it from being switched on
again!
• No special maintenance in operation.
• The bearing holding the coupling and the motor
bearings are lubricated for their total lifetime and
do not require any lubrication.
• Keep the pump and the motor-converter per-
fectly clean.
• In case of prolonged stopping, if there is no risk
of frost, it is better not to drain the pump.

8. Faults, causes and remedies
Faults should only be remedied by qualified per-
sonnel! Observe the safety instructions.
Relays
The converter is fitted with 2 output relays
aimed for an interface to centralized control.
ex.: control box, pumps control.
SBM relay :
This relay can be configured in the « Service »
menu < 5.7.6.0 > in 3 operating states.
State: 1 (factory setting)
« Available transfer » relay (normal operating for
this pump type).
The relay is activated when the pump runs or is
in a position to run.
When a first defect appears or by mains supply
cutoff (the pump stops), the relay is deactiveted.
Information is given to the control box, regarding
the availability of the pump, even temporarily.
State: 2
« Run transfer » relay.
The relay is activated when the pump runs.
State: 3
« Power on transfer » relay.
The relay is activated when the pump is con-
nected to the network.
SSM relay:
« Failures transfer » relay.

• To avoid any locking of the shaft and the hydrau-
lic unit during the freezing period, drain the
pump by removing the plug (item 6) and filling
plug (item 5). Screw both plugs back in without
tightening them.
Replacement frequencies
NOTE: These are only recommendations, the
replacement frequency depends on the operat-
ing conditions of the unit , i.e.:
• Temperature, pressure and type of conveyed
fluid for the mechanical seal.
• Load and ambient temperature for the motor and
the other components.
• Starting frequency: continuous or intermittent
running.
