8.4 Setting of LC 221
Only the start level corresponding to the inlet level to the
collecting tank needs to be set. All other values are preset but
can be adjusted if required.
Select the height of the inlet pipe, 180, 250 or 315 mm above
floor level, using the buttons
and
, and press the button
to save the desired value. If the height of the inlet pipe is between
two values, e.g. 220 mm above the floor, choose the nearest
lower value (180 mm). Now the controller is ready for automatic
mode.
The following values can be changed, if necessary:
Start level
The start level must be set according to the inlet pipe height
above floor level (180, 250 and 315 mm). Stop and alarm levels
are preset.
Rated current
Preset value from factory according to the rated current of the
motor. The protection against pump blockage is a preset value for
overcurrent.
Stop delay
The stop delay increases the effective volume and reduces the
quantity of residual water in the tank. It also prevents water
hammer. The non-return valve closes more softly. The preset
value is 0.
Start delay
Normally no need to make adjustments for lifting stations except
on a house boat or pontoon boat. The preset value is 0.
Alarm delay
High temporary inflow can cause short-time high-level alarm. This
situation may arise when a backwash filter of a swimming pool is
connected to Multilift MOG or MDG. The preset value is 5
seconds.
Maintenance interval
The maintenance/service interval can be set to 0, 3, 6 or 12
months and is indicated in the "SERVICE" display (no acoustic
signal).
Reset alarm
It is possible to set the controller to reset some alarms
automatically when the fault disappears; however, most alarms
must be reset manually. See section
. The preset value is AUTO.
Reset to factory settings
The controller will reboot, and startup settings will have to be
made again. See section
.
8.4.1 External alarm
Lifting stations are often installed in sumps below the basement
of buildings. That is the deepest point in the building, and an
additional alarm level switch can be placed outside the lifting
station to detect flooding caused by leakages, pipe bursts or
groundwater inflow.
The external alarm can be connected to a level switch (230 V / 2
A) at terminals 13, 14.
