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. A1, ref. 1).
The <7.0.0.0> menu is called up.
• Turn the Red button 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 al-
lowed for setting.
• Return the switch 2 on OFF position (Fig. 4, ref. S).
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. A2, A3, A9)
Regulation with a pressure sensor and setting
point (internal or external).
In case of variable pressure mode put off the zero
flow delay time in menu 5.7.3.0.
• The addition of a pressure sensor allows pressure
regulation of the pump. The system should have
an expansion or compression tank attached to
the system, pressurized to 5 PSI less than the
minimum maintenance pressure required by 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 minimum vo-
lume of 8L.
• 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 ex-
ternal).
9. Maintenance
All servicing should be performed by an autho-
rized service representative!
WARNING! Electrical shock hazard!
Dangers caused by electrical energy must be ex-
cluded.
All electrical work must be performed after the
electrical supply has been switched off and se-
cured against unauthorized switching.
WARNING! Risk of scalding!
At high water temperatures and system pressure
close isolating valves before and after the pump.
First, allow pump to cool down.
- These pumps are maintenance free.
-
Optional cartridge seals allow for rapid field re -
pairs by avoiding motor replacement during seal
exchanges.
- Always keep the pump perfectly clean.
- Pumps which are not being used in conditions
where condensation can occur should be drained
to avoid damage: Close the guard valves, open
completely the drain-priming plug and the air
bleed screw.
DANGER!
Danger of death !
The pump has a strong magnetic field in ope -
ration. If you have a pacemaker, this presents a
severe danger and may cause death or serious
injury.
• Don’t open the motor!
• Repairs to the electronic controls and motors are
to be handled only by Authorized agents.
