Access lock
In order to lock the pump settings, it is possible
to use the « Access lock ».
To activate or deactivate it, proceed as follows:
• Put the switch 2 on ON position (Fig. 4). The
<7.0.0.0> menu is called up.
• Turn the encoder to activate or deactivate the
locking. The current state of the locking is repre-
sented with the following symbols:
• Return the switch 2 on OFF position (Fig. 4). The
display returns to the status page.
8.3.6 Configurations
NOTE: If the pump is delivered as separate part,
not integrated into a system we mounted, the
standard configuration mode is
« Speed control ».
« Speed control » mode (Fig. 1, 2)
Setting of the frequency by hand or external
control.
• For the starting up, we recommend to set the
motor speed at 2400 RPM.
« Constant pressure » and
« Variable pressure » mode (Fig. 6-7-8)
Regulation with a pressure sensor and setting
point (internal or external).
• The addition of a pressure sensor (with tank;
sensor kit delivered as accessories) allows a
pressure regulation of the pump (with no water
in the tank, pressurize the tank to a pressure 0.3
bar less than the pressure regulation of the
pump).
• The accuracy of the sensor shall be ≤ 1% and it is
used between 30 % and 100 % of the measuring
scale range. The tank must have a useful volume
of 8L minimum.
• For the starting up, we recommend a pressure set
value at 60% of its maximum pressure.
« P.I.D. control » mode
Regulation with a sensor (temperature, flow...) by
P.I.D.control and setting point (internal or exter-
nal).

Lock active: Parameters are locked,
the access to menus is allowed only
on reading.
Lock inactive: Parameters can be
changed, the access to menus is allo-
wed for setting.
9. Maintenance
All servicing should be performed by an
authorized service representative!
WARNING! Electrical shock hazard!
Dangers caused by electrical energy must be
excluded.
All electrical work must be performed after the
electrical supply has been switched off and
secured against unauthorized switching.
WARNING! Risk of burn!
At high water temperatures and system pressure
close isolating valves before and after the pump.
First, allow pump to cool down.
- No special maintenance in operation.
- Keep the pump and the motor-converter per-
fectly clean.
- Pumps which are not being used during periods
of frost should be drained to avoid damage:
Close the guard valves, open completely the
drain-priming plug and the air bleed screw.
- The bearing holding the coupling and the motor
bearings are lubricated for their total lifetime and
do not require any lubrication.
- On pumps equipped with greaser under bearing
box, see regreasing instructions written on stick-
er put on it:
- On other models, the bearing holding the cou-
pling is lubricated for its total lifetime.
- It is recommended to grease the shaft end as
well as the coupling boring with a high adhering
grease (type D321R Molikote or 8191 Loctite for
example) to facilitate any further diassembling.
- The mechanical seal does not require any main-
tenance in operation. It must never operate dry.
