1. General
The LCD 108 controller is designed for the control of pumps in
wastewater systems.
Type key:
1.1 Applications
The LCD 108 enables:
• control of two pumps based on signals from float switches,
• automatic pump changeover (even distribution of operating
hours on both pumps),
• selection of automatic test run during long periods of inactivity
(every 24 hours),
• battery back-up in case of mains supply failure (accessory for
certain variants),
• starting delay within the range from 0 to 255 sec. (random)
after returning from battery operation to mains operation
(resulting in an even mains load when several pumping
stations are started up at the same time),
• selection of automatic alarm resetting,
• selection of automatic restarting,
• setting of stop delays matching the actual operating
conditions,
• indication of liquid level,
• alarm indication of:
- inadmissibly high liquid level,
- overload (via motor protection relay),
- overtemperature (via PTC resistance or thermal switch in
motor),
- wrong phase sequence (only certain variants),
- mains supply failure (only certain variants),
- defective float switch.
As standard, the LCD 108 has one alarm output for common
alarm. Certain variants have an additional alarm output for
separate high-level alarm.
Furthermore, the controller incorporates a buzzer (only certain
variants).
1.2 Variants
The actual controller type, voltage variant, etc. are stated in the
type key on the nameplate situated on the side of the controller
cabinet.
The LCD 108 is available for direct-on-line starting.
The LCD 108 can be connected and set to operation/control in 4
different ways, see sections 3. to 6.:
• Section 3. Systems for parallel operation with 3 float switches.
(Electrodes can also be used.)
• Section 4. Systems for parallel operation with 4 float switches.
(Electrodes can also be used.)

The LCD 108 controller and an EEx barrier, if
required, must not be installed in explosion hazard
areas.
Only float switches approved for use in explosion
hazard areas may be used. The float switches must
be connected via an EEx barrier, e.g. Grundfos
number 96440300.
The LCD 108 can be mounted at ambient temperatures ranging
from –30 °C to +50 °C.
Enclosure class: IP 65.
When installed outdoors, the LCD 108 must be placed in a
protective shed or cupboard.
The LCD 108 must not be exposed to direct sunlight.
2.2 Mounting of LCD 108 for direct-on-line starting
Before mounting, remove the transport protectors, if any, from
inside the cabinet.
Mount the LCD 108:
• on a plane wall surface,
• with the Pg cable entries pointing downwards
(additional Pg cable entries, if required, must be fitted in the
bottom plate of the cabinet),
• with four screws through the mounting holes in the back plate
of the cabinet. The mounting holes must be bored with a 4 mm
bore. Fit the screws into the mounting holes and tighten
securely. Fit the plastic caps supplied with the controller on the
screws (IP 65).
Figure 1 shows the terminals listed under positions 2 and 3.
3. Systems for parallel operation with 3 float
switches
Description (see also page 23 or 24):
The pumps are controlled by the liquid level in the pit.
• When the float switch, pos. 1, registers liquid, the first pump is
started.
• When the float switch, pos. 2, registers liquid, the next pump is
started.
• When the float switch, pos. 1, does not register any liquid, the
"stop delay" is initiated (can be set). After expiration of the
stop delay, both pumps are stopped.
• The pumps operate alternately.
The top float switch, pos. 3, activates the high-level alarm.
Before starting any work on pumps used to pump
liquids which could be constituted as being
hazardous to health, thorough cleaning/venting of
pumps, pits, etc. must be carried out according to
local regulations.
Before making any connections in the LCD 108 or
work on pumps, pits, etc., it must be ensured that the
electricity supply has been switched off and that it
cannot be accidentally switched on.
3.1 Electrical connection
Parallel operation with 3 float switches, pages 23 or 24.
Before starting work on the system, switch off the

3.2 Setting
Parallel operation with 3 float switches, pages 23 and 24.
The module CU 212 has a 10-pole DIP switch in the bottom right
corner, see fig. 2.
Note: During the setting of the DIP switch, the controller must
always be dead for at least 1 minute to achieve the correct
configuration during start-up after change of the DIP switch
setting.
The DIP switch setting offers the following possibilities:
• selection of starting delay and automatic test run (switch 4),
• setting of stop delay (switches 5, 6 and 7),
• selection of automatic alarm resetting (switch 9),
• selection of automatic restarting (switch 10).
At this setting, the start-up is delayed within the range
from 0 to 255 sec. (random) after the electricity supply
has been switched on when the liquid level is
sufficiently high.
Automatic test run carried out every 24 hours.
After the electricity has been switched on, the pump will
start immediately when the liquid level is sufficiently
high.
No automatic test run.
• Switches 5, 6 and 7, stop delay:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
The stop delay is the time from the stop signal is given until the
pump is stopped.
It must be ensured that the pump is not running dry.
0 sec. 60 sec.
15 sec. 90 sec.
30 sec. 120 sec.
45 sec. 180 sec.
•Switch 8:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
Switch 8 has no function in connection with the actual
application (parallel operation with 3 float switches,
pages 23 and 24), but this setting must be maintained!
•Switch 9, automatic alarm resetting:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
Fig. 2
Set the DIP switch as shown in fig. 2.
Each individual switch (1 to 10) of the DIP switch can be set to
position OFF or ON.
During the setting of the DIP switch, the controller must always
be dead for at least 1 minute to achieve the correct configuration
during start-up after change of the DIP switch setting.
Set the switches 1 to 10 as follows:
•Switches 1, 2 and 3, application type:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
This setting determines the actual application type
(parallel operation with 3 float switches, pages 23
and 24).
•Switch 4, starting delay and automatic test run
(only in the case of battery back-up):
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
This setting ensures automatic resetting of alarm
signals to external alarm devices and the built-in
buzzer. However, an alarm signal will only be reset if
the cause of the fault no longer exists.
At this setting, the alarm signal must be reset manually
by means of the reset button (the reset button is
described in section 3.5).
•Switch 10, automatic restarting:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
TM01 6870 2308
This setting enables automatic restarting after the PTC
resistance/thermal switch of the motor has cut out the
pump. Restarting will not be carried out until the motor
has cooled to normal temperature.
When the pumps connected are used in explosion
hazard areas, switch 10 must not be in this
position!
At this setting, the pump must be restarted manually after
the PTC resistance/thermal switch of the motor has cut
out the pump. To restart the pump, push the ON-OFFAUTO selector switch into position OFF for a short period
(the ON-OFF-AUTO selector switch is described in
section 3.5).
When the pumps connected are used in explosion
hazard areas, switch 10 must be in this position!

3.4 Battery back-up functions
Parallel operation with 3 float switches, pages 23 and 24.
If a back-up battery for CU 212 (accessory for certain variants) is
installed, the following functions will be carried out if the normal
electricity supply to the LCD 108 fails (see also the illustrations
below):
• The common alarm is active, the red indicator light is on –
cannot be reset!
• If the external alarm device for common alarm is supplied from
an external power source, this device will be active – cannot
be reset by means of the reset button!
• The built-in buzzer (only certain variants) is activated – can be
reset by means of the reset button!
• If the liquid level in the pit rises above the level for high-level
alarm, the top orange indicator light will be flashing and the
second orange indicator light from the top will be permanently
on.
• If the starting delay function and automatic test run were
selected (switch 4 of the DIP switch), the start-up will be
delayed after the electricity supply has been switched on when
the liquid level is sufficiently high, see section 3.2.

3.5 Reset button and ON-OFF-AUTO selector switch
21
Parallel operation with 3 float switches, pages 23 and 24.
The reset button is a push-button for manual resetting of alarm signals to external alarm devices and the built-in
buzzer (i.e. not for resetting of the alarm memory as this is reset by means of the ON-OFF-AUTO selector switch,
see position OFF ( )).
Even if the fault condition still exists, the external alarm devices and the built-in buzzer will be reset when the reset
button is pressed.
The ON-OFF-AUTO selector switch for each pump has three different positions:
ON ( ), top position:
• The pump will start when the selector switch is pushed into this position (unless the motor protection relay has cut
out the pump).
• If the PTC resistance/thermal switch of the motor registers overtemperature, the pump will not be switched off.
Note: It is the user’s responsibility to decide how long the pump is to run with this fault indication. Over a long
period, the pump will be damaged!
In explosion hazard areas, switch 10 of the DIP switch must be set as stated in section 3.2. Consequently,
the pump cannot be started when the PTC resistance/thermal switch of the motor registers overtemperature.
OFF ( ), middle position:
• The pump cannot start when the selector switch has been set to this position.
• The alarm memory is reset by pushing the selector switch into position OFF ( ). The alarm memory is the light
indication of a fault condition which has disappeared. If a fault condition still exists when the selector switch is
pushed into position ON ( ) or AUTO ( ), the alarm indication will be repeated immediately.
AUTO ( ), bottom position:
• The pump is controlled by the input signals from the float switches and the pump according to the selected
DIP switch setting.
• Alarm signals will automatically be reset. Switch 9 of the DIP switch can, however, be set to manual resetting
which is carried out by means of the reset button, see section 3.2.
• The pump will restart automatically when a given fault condition disappears. However, this is dependent on the
setting of switch 10 of the DIP switch, see section 3.2.
• When the pump starts automatically after a fault condition which has disappeared, the indicator light will continue
to show the fault condition (alarm memory) and the indication can only be removed by resetting the alarm memory,
see position OFF ().
4. Systems for parallel operation with 4 float
switches
Description (see also page 25 or 26):
The pumps are controlled by the liquid level in the pit.
• The float switch, pos. 2, starts the first pump.
• The float switch, pos. 3, starts the next pump.
• The float switch, pos. 1, stops both pumps after expiration of
the "stop delay" (can be set).
• The pumps operate alternately.
• The top float switch, pos. 4, activates the high-level alarm.
Before starting any work on pumps used to pump
liquids which could be constituted as being
hazardous to health, thorough cleaning/venting of
pumps, pits, etc. must be carried out according to
local regulations.
Before making any connections in the LCD 108 or
work on pumps, pits, etc., it must be ensured that the
electricity supply has been switched off and that it
cannot be accidentally switched on.

Parallel operation with 4 float switches, pages 25 and 26.
If a back-up battery for CU 212 (accessory for certain variants) is
installed, the following functions will be carried out if the normal
electricity supply to the LCD 108 fails (see also the illustrations
below):
• The common alarm is active, the red indicator light is on –
cannot be reset!
• If the external alarm device for common alarm is supplied from
an external power source, this device will be active – cannot
be reset by means of the reset button!
• The built-in buzzer (only certain variants) is activated – can be
reset by means of the reset button!
• If the liquid level in the pit rises above the level for high-level
alarm, the top orange indicator light will be flashing and the
second orange indicator light from the top will be permanently
on.
• If the starting delay function and automatic test run were
selected (switch 4 of the DIP switch), the start-up will be
delayed after the electricity supply has been switched on when
the liquid level is sufficiently high, see section 4.2.
The table below shows the situations which may occur if the
normal electricity supply to the LCD 108 fails and a back-up
battery is connected:
= the indicator light is off.
= the indicator light is on.

4.5 Reset button and ON-OFF-AUTO selector switch
21
Parallel operation with 4 float switches, pages 25 and 26.
The reset button is a push-button for manual resetting of alarm signals to external alarm devices and the built-in
buzzer (i.e. not for resetting of the alarm memory as this is reset by means of the ON-OFF-AUTO selector switch,
see position OFF ( )).
Even if the fault condition still exists, the external alarm devices and the built-in buzzer will be reset when the reset
button is pressed.
The ON-OFF-AUTO selector switch for each pump has three different positions:
ON ( ), top position:
• The pump will start when the selector switch is pushed into this position (unless the motor protection relay has cut
out the pump).
• If the PTC resistance/thermal switch of the motor registers overtemperature, the pump will not be switched off.
Note: It is the user’s responsibility to decide how long the pump is to run with this fault indication. Over a long
period, the pump will be damaged!
In explosion hazard areas, switch 10 of the DIP switch must be set as stated in section 4.2. Consequently,
the pump cannot be started when the PTC resistance/thermal switch of the motor registers overtemperature.
OFF ( ), middle position:
• The pump cannot start when the selector switch has been set to this position.
• The alarm memory is reset by pushing the selector switch into position OFF ( ). The alarm memory is the light
indication of a fault condition which has disappeared. If a fault condition still exists when the selector switch is
pushed into position ON ( ) or AUTO ( ), the alarm indication will be repeated immediately.
AUTO ( ), bottom position:
• The pump is controlled by the input signals from the float switches and the pump according to the selected DIP
switch setting.
• Alarm signals will automatically be reset. Switch 9 of the DIP switch can, however, be set to manual resetting
which is carried out by means of the reset button, see section 4.2.
• The pump will restart automatically when a given fault condition disappears. However, this is dependent on the
setting of switch 10 of the DIP switch, see section 4.2.
• When the pump starts automatically after a fault condition which has disappeared, the indicator light will continue
to show the fault condition (alarm memory) and the indication can only be removed by resetting the alarm memory,
see position OFF ().

• The float switch, pos. 4, starts the next pump.
• The float switch, pos. 1, stops both pumps after expiration of
the "stop delay" (can be set).
• The pumps operate alternately.
• The float switch, pos. 3, activates the high-level alarm.
Before starting any work on pumps used to pump
liquids which could be constituted as being
hazardous to health, thorough cleaning/venting of
pumps, pits, etc. must be carried out according to
local regulations.

100 % standby operation, pages 27 and 28.
The module CU 212 has a 10-pole DIP switch in the bottom right
corner, see fig. 8.
Note: During setting, the controller must be off circuit for at least
1 minute to ensure the correct configuration during start-up after
change of the DIP switch setting.
The DIP switch setting offers the following possibilities:
• selection of starting delay and automatic test run (switch 4),
• setting of stop delay (switches 5, 6 and 7),
• selection of automatic alarm resetting (switch 9),
• selection of automatic restarting (switch 10).
The LCD 108 must be connected in accordance with
the rules and standards in force for the application in
question.
The operating voltage and frequency are marked on the controller
nameplate. Make sure that the controller is suitable for the
electricity supply on which it will be used.
All cables/wires must be fitted through the Pg cable entries and
gaskets (IP 65).
Maximum back-up fuse is stated on the controller nameplate.
If required according to local regulations, an external mains
switch must be installed.
Note: If the PTC resistance/thermal switch of the motor is
connected, the factory-fitted short-circuit jumper must be
removed (terminals T11-T21, T12-T22). For correct installation of
PTC resistor/thermal switch, see the installation and operating
instructions of the pump.
Single-phase motors must be connected to an external operating
capacitor and in certain cases also to a starting capacitor. Further
details can be found in the installation and operating instructions
for the pump in question.
Float switches placed in an explosion hazard area
must be connected via an EEx barrier, e.g. Grundfos
number 96440300.
The EEx barrier must not be installed in the explosion
hazard area.
Equipment used in explosion hazard areas must in
each individual case have been approved for this
particular application. Furthermore, the cables into
the explosion hazard area must be laid in accordance
with local regulations.
Note: Float switches of the same type as Grundfos product
number 96003332 or 96003695, i.e. float switches with
gold-plated contacts suitable for low voltages and currents
(40 V/100 mA), must be used. All EEx-approved float switches
are also suitable.

•Switch 9, automatic alarm resetting:
When the DIP switch setting is changed, the controller must
be switched off for at least 1 minute!
This setting ensures automatic resetting of alarm
signals to external alarm devices and the built-in
buzzer. However, an alarm signal will only be reset if
the cause of the fault no longer exists.
At this setting, the alarm signal must be reset manually
by means of the reset button (the reset button is
described in section 6.5).

6.4 Battery back-up functions
Full-control operation, pages 29 and 30.
If a back-up battery for CU 212 (accessory for certain variants) is
installed, the following functions will be carried out if the normal
electricity supply to the LCD 108 fails (see also the illustrations
below):
• The common alarm is active, the red indicator light is on –
cannot be reset!
• If the external alarm device for common alarm is supplied from
an external power source, this device will be active – cannot
be reset by means of the reset button!
• The built-in buzzer (only certain variants) is activated – can be
reset by means of the reset button!
• If the starting delay function and automatic test run were
TM01 6397 3902
selected (switch 4 of the DIP switch), the start-up will be
delayed after the electricity supply has been switched on when
the liquid level is sufficiently high, see section 6.2.
The table below shows the situation which may occur if the
normal electricity supply to the LCD 108 fails and a back-up
battery is connected:
= the indicator light is off.
= the indicator light is on.
= the indicator light is flashing.
Mains supply failure:
• The common alarm is active.
The red indicator light is on.
• The green indicator light (electricity
supply switched on) is off.

6.5 Reset button and ON-OFF-AUTO selector switch
21
Full-control operation, pages 29 and 30.
The reset button is a push-button for manual resetting of alarm signals to external alarm devices and the built-in
buzzer (i.e. not for resetting of the alarm memory as this is reset by means of the ON-OFF-AUTO selector switch,
see position OFF ( )).
Even if the fault condition still exists, the external alarm devices and the built-in buzzer will be reset when the reset
button is pressed.
The ON-OFF-AUTO selector switch for each pump has three different positions:
ON ( ), top position:
• The pump will start when the selector switch is pushed into this position (unless the motor protection relay has cut
out the pump).
• If the PTC resistance/thermal switch of the motor registers overtemperature, the pump will not be switched off.
Note: It is the user’s responsibility to decide how long the pump is to run with this fault indication. Over a long
period, the pump will be damaged!
In explosion hazard areas, switch 10 of the DIP switch must be set as stated in section 6.2. Consequently,
the pump cannot be started when the PTC resistance/thermal switch of the motor registers overtemperature.
OFF ( ), middle position:
• The pump cannot start when the selector switch has been set to this position.
• The alarm memory is reset by pushing the selector switch into position OFF ( ). The alarm memory is the light
indication of a fault condition which has disappeared. If a fault condition still exists when the selector switch is
pushed into position ON ( ) or AUTO ( ), the alarm indication will be repeated immediately.
AUTO ( ), bottom position:
• The pump is controlled by the input signals from the float switches and the pump according to the selected
DIP switch setting.
• Alarm signals will automatically be reset. Switch 9 of the DIP switch can, however, be set to manual resetting
which is carried out by means of the reset button, see section 6.2.
• The pump will restart automatically when a given fault condition disappears. However, this is dependent on the
setting of switch 10 of the DIP switch, see section 6.2.
• When the pump starts automatically after a fault condition which has disappeared, the indicator light will continue
to show the fault condition (alarm memory) and the indication can only be removed by resetting the alarm
memory, see position OFF ().

7. Start-up
Before starting any work on pumps used to pump
liquids which could be constituted as being
hazardous to health, thorough cleaning/venting of
pumps, pits, etc. must be carried out according to
local regulations.
Before making any connections in the LCD 108 or
work on pumps, pits, etc., it must be ensured that the
electricity supply has been switched off and that it
cannot be accidentally switched on.
Prior to start-up, the connection and DIP switch setting must have
been carried out according to sections 3. to 6.
Start-up must be carried out by authorized personnel.
Proceed as follows:
1. Check whether the float switches have been connected
according to the wiring diagram for the actual application.
2. Check that the pump inlets are submerged in the liquid to be
pumped.
3. Set the motor protection relays to the rated current stated on
the nameplates.
4. Warning:
Ensure that the short-circuit protection is suitable for
the installation.
5. Switch on the electricity supply.
Three-phase pumps only: Check for wrong phase sequence,
(the pump cannot be started if the phase sequence is wrong!).
6. Start the pumps, see section 3.5, 4.5, 5.5 or 6.5.
7. Check that the pumps are not running dry. The risk of dry
running can be eliminated by a renewed time setting by means
of the DIP switch according to section 3.2, 4.2, 5.2 or 6.2 and/
or by moving the float switches.
8. Three-phase pumps only: Check whether the direction of
rotation of the pumps is correct according to the installation
and operating instructions for the pump in question.
9. Select the required operating mode by means of the ON-OFFAUTO selector switch, see section 3.5, 4.5, 5.5 or 6.5.
8. Maintenance
Before starting any work on pumps used to pump
liquids which could be constituted as being
hazardous to health, thorough cleaning/venting of
pumps, pits, etc. must be carried out according to
local regulations.
Before making any connections in the LCD 108 or
work on pumps, pits, etc., it must be ensured that the
electricity supply has been switched off and that it
cannot be accidentally switched on.
During normal application and operation, the controller LCD 108
is maintenance-free.
However, it is advisable to carry out minor checks of the LCD 108
controller, pump pits, tanks, pumps, etc. at suitable intervals.
These checks should be carried out by authorized personnel.
• Check the gaskets of the LCD 108 cabinet front and those of
the Pg cable entries.
• Check the cable entries for the explosion hazard area.
• Check for possible deposits/sludge build-up in the pump pit/
tank. Sludge may settle in areas with almost stagnant liquid.
• Check for beginning sludge build-up around the float switches.
• Check for possible blockage on the suction side of the pump.
A blockage will typically be a large solid object.
• If the LCD 108 has been installed in a particularly aggressive
environment, it is advisable to check the motor protection contacts in order to identify possible chemical attack resulting in
corrosion. In typical installations, the motor protection contacts
will work for several years and do not require any inspection.
Note: The list above is not complete. The LCD 108 may be
installed in systems, installations and/or environments which
require thorough and regular maintenance.
