To display menu options use navigation keys ▲
and ▼ according to the following scheme:
• Main screen - ▲ - Pump's start up meter - ▲ -
First menu level - ▲ - Subsequent key press menu
scrolling levels from 1 upwards.
• Main screen - ▼ - Last menu level - ▼ - Subse-
quent key press menu scrolling levels from the
last level down.
If no key is pressed, then after 8 seconds the
menu will be closed.
The upper line of the each display shows the
name of the option, while the lower line shows
its settings which can be modified. In order to
change a settings press "OK". The current name
of the option will start to flash. This allows to set
up parameters with navigation keys ▲ and ▼. If
you hold one of the keys pressed for longer, the
value being set will change more rapidly. If you
press the key "OK" again, the new value will be
saved.
The table below displays all the menu options
along with explanations.

English
When the pump's current
falls below the set value,
the message "Dry run" will
be displayed, and after the
expiration of adjusted time
("Dry run time"), the device
will turn the pump off and
report a failure. The pump
can be turned on again
after the failure is deleted
with the "OK" key. Current
of the pump decrease if
there is no liquid in the
tank or if the delivery pipe-
line is clogged.
If the pump's current
exceeds the set value, the
message "Overcurrent" will
be displayed. If this state
remains unchanged for a
specified period of time,
the device turns the pump
off and reports a failure.
The pump can be started
again after acceptance is
made with the "OK" key.
Indicates how long the
pump is going to work
after the pump's current
falls below the set value
of "Minimum current".
After this period of time
there will be a break in the
pump's work, or it will be
stopped in failure mode.
The time of the break in
the pump's work after it is
stopped as a result of a dry
run. The time remaining till
the end of the break will be
displayed. No break occurs
if the value of the setting
"Dry run cycles"
is 1.
Number of work cycles
at the dry run state, after
which the pump is stopped
and the failure is reported.
Delay of pump's start up
after the power supply
voltage decays – the pump
can be turned on after a
specified period of time.
The display shows the
time, which remains to
the pump's start up. This
setting is to prevent pumps
in units situated next to
each other from simultane-
ous startup after decay of
voltage.
