8.5.3 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, item 18).
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:
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
allowed for setting.
• Return the switch 2 on OFF position (Fig. 4, item
18). The display returns to the status page.
9. Commissioning
NOTE: If the pump is delivered as separate part,
not integrated into a system we mounted, the
standard configuration mode is
« Speed control ».
9.1 Configurations
9.1.1 « 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.
9.1.2 « Constant 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.
• 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.
9.1.3 « P.I.D. control » mode
Regulation with a sensor (temperature, flow,...)
by P.I.D.control and setting point (internal or
external).
9.2 Preliminary rinsing
The hydraulic features of every pump is tested in
factory, some water may remain in them. It is
recommended for hygien purposes, to carry out a
rinsing of the pump before any using with
potable water supply.
9.3 Filling - degassing
CAUTION!
Danger of material damage!
Never operate the pump dry, even briefly!
Pump in load (Fig. 2).
• Close the discharge valve (item 3).
• Open the venting plug (item 5), the suction valve
(item 2) and completely fill the pump.
• Close the venting plug only after water flows out
and complete aeration.
WARNING!
Danger of burn!
In hot water, a stream of water may escape from
the venting plug port.
• Take all required precautions as regards persons
and motor-converter.
Pump in suction (Fig. 1).
Two possible cases:
1st case (Fig. 5.1).
• Close the discharge valve (Fig. 1, item 3), open
the suction valve (Fig. 1, item 2).
• Remove the venting plug (Fig. 1, item 5).
• Unscrew about 4 turns the bottom drain-priming
plug (Fig. 1, item 6) located on the pump casing.
• Put a funnel into the venting plug port and com-
pletely fill the pump and the suction pipe.
• After water flows out and total air exit, filling is
achieved.
• Screw the venting plug and the bottom drain-
priming plug back in.
2st case (Fig. 5.2).
• Filling can be made easier by fitting a vertical
pipe (Fig. 5, item 14) fitted with a Ø ½" stopcock
and a funnel, on the suction pipe of the pump.
NOTE: The length of the pipe must be at least 50
mm higher than the venting plug level.
• Close the discharge valve (Fig. 1, item 3), open
the suction valve (Fig. 1, item 2).
• Open the stopcock (Fig. 5, item 14) and the
venting device (Fig. 1, item 5).
• Unscrew about 4 turns the drain-priming plug
(Fig. 1, item 6).
• Completely fill the pump and the suction pipe
until water flows out of the venting plug (Fig. 1,
item 5).
• Close the stopcock (Fig. 5, item 14) (which can
be left in place), remove the pipe, close the
venting device (Fig. 1, item 5) and screw again
the drain-priming plug (Fig. 1, item 6).
CAUTION!
Risk of misuse!
Pump in load and in « Constant pressure » mode,
the detection at zero flow can not run.
• Set the non-return valve before the pressure
sensor (i.e. at pump suction if the sensor is
mounted on this one – Fig. 6).
9.4 Starting up
WARNING!
Danger of burn!
Depending on conveyed fluid and the operating
cycles of the pump, surface temperature (pump,
motor) can exceed 68°C.
