TECHNICAL INFORMATION
92 87-900-986-01 (
C
)
Switching from a parameter to the previous parameter
(using the “
PREVIOUS”
key) indicates the intention to
abort any changes made to the specific parameter.
Abort is indicated by the caption “
Changes aborted
”
that is displayed for approx. 1 second before moving to
the previous parameter.
The configuration environment has a tree-like structure
and permits “circular” navigation; on reaching the end
of a branch, the user is returned automatically to the
start of this. Navigation can proceed in a forwards
(
NEXT
button) or backwards (
PREVIOUS
button)
direction
It is possible to enter a sub-branch by pressing the
“
INCREASE
” button..
If no buttons are pressed for more than 1 minute, the
controller automatically quits the programming
environment canceling any modifications made to the
current parameter.
The figure below shows the first level of the
configuration menu and the links to the respective
second level menus (indicated below).

This menu contains all the parameters that have a
direct effect on driving of the pump.
•
HIGH SPEED
: Sets (in Hz) the speed of rotation of
the pump when the low-speed function is not
active.
•
LOW SPEED:
Sets (in Hz) the speed of rotation of
the pump when the low-speed function is active.
•
SOFT START:
enables (YES) or disables (NO) the
soft start function. This parameter is visible only if
the controller is configured in FRONT mode.
•
EXTERNAL FAN CNF:
Makes it possible to select
driving mode of the external cooling fan. Possible
options:
-
ALWAYS ON: the cooling fan is always ON
-
OFF_LIMPOWER: 10 seconds after the pump
has reached NORMAL status, the fan is
switched off and the driving power of the pump
is reduced to 50 W
-
SERIAL: the cooling fan is controlled directly
via the serial port.
