3.2 Power Supply and Consumption
Figure 7 shows the typical power consumption of the system. If other AC/DC power supplies than the
standard specified ones are used, it is recommended to evaluate them under demanding operating situations
like fast braking from maximum speed and during power on and take-off of the impeller.
Figure 7: Electrical power consumption
(Controller LPC-300.1 with pump head LPP-300.1)
3.3 Temperature Monitoring
To avoid overheating of the system, the controller and motor temperatures are monitored. If the controller
temperature exceeds 70°C (158°F) or the motor temperature 90°C (194°F) for a duration of more than 10
minutes, the system goes into an error state and the pump stops. At 80°C (176 F) controller temperature or
100°C (212°F) motor temperature, the system stops immediately.

3.4 Thermal Management
3.4.1 Motor Temperature
At 25 0C (77 F) ambient temperature and liquid temperature < 70 0C (158 F) the inside motor temperature is
below 75 0C (167 F) for all operational points shown in Figure 3. The maximum surface temperature is
significantly below this inside temperature. If the ambient temperature is up to 40 0C (104 F) liquid
temperature should not exceed 55 0C (131 F) to fulfill above motor conditions.
If the above specified conditions are exceeded or the motor is placed in an environment with poor circulation
active cooling means are recommended in order to not run into the thermal limit (90 0C / 194 F) or
significantly reduce the MTBF.
3.4.2 Controller Temperature
At ambient temperature < 40 0C (104 F) the controller temperature is below 60 0C (140 F) for all operational
points shown in Figure 3. The maximum surface temperature is below this inside temperature.
If the specified conditions are exceeded or the controller is placed in an environment with poor circulation
active cooling means are recommended in order to not run into the thermal limit (70 0C / 158 F).
3.5 Hydraulic Circuit Design
Following general design rules shall be considered for a robust operation of the pump system considering
efficiency and optimum priming behavior:
1. The general rule for optimum priming behavior is to minimize the pressure drop in the inlet
circuit and avoid negative pressure at the inlet of the pump head.
2. Minimize tubing length at the inlet of the pump head and maximize the ID (not smaller than the
pump head inlet ID of 22.5 mm is recommended). This reduces the pressure drop and the
tendency of cavitation.
3. Avoid any restrictions, valves, elbows, bended tubing and sharp edges at the inlet circuit of the
pump head, which potentially causes cavitation resulting in gas bubble collection in the pump
head with the danger of priming loss.
4. Place the pump at the lowest point of the hydraulic circuit. Optimum is as much as possible
below a tank or reservoir. This optimizes priming behavior and removal of gas bubbles.
5. Keep the liquid level in the reservoir tank or bag as high as possible, which increases the inlet
pressure of the pump head and minimized heat up of the liquid.
6. In general the pump system placement and circuit shall be designed that gas bubbles can leave
the pump housing and that the pump head remains primed.
7. To minimize heat up of the liquid the overall pressure drop in the hydraulic circuit shall be
reduced as much as possible.
8. It shall be avoided to pump longer times against a closed valve, which can cause heat-up of the
liquid.
9. At higher liquid temperature above rules become more important due to higher cavitation
tendency of the liquid.
10. Load and stress at the inlet and outlet by heavy tubing and improper mounting alignment shall
be avoided as this can cause leakage issues due to distortion of the plastic pump housing.
Contact the Levitronix®Technical Service department (see Section 8) for more detailed considerations and
support on the design of the hydraulic circuit.

4.1.2 Installation Instructions
!
WARNING
Hazardous voltage may be present.
Always isolate the electrical power supply before making or changing
connections to the unit.
In case of the usage of an inadequate AC/DC power supply, mains
voltages may be present (even if the system is designed for 48VDC).
The usage of a galvanic separated power supply, which is certified by
a 3rd party (UL or CE), is highly recommended.
The controller housing must be properly grounded and placed in a spill
protected electrical cabinet. Use one of the DIN-rail screws on the back
side of the controller housing.
Do not use different and longer screws, which may result in short-
circuit within the controller.
1. The controller and the power supply casings must be grounded. The screws of the DIN-rail
bracket can be used for grounding (see Figure 11).
2. Connect the two motor connectors (“POWER OUTPUT” and “SENSORIC”) to the controller.
3. Section 4.1.3 describes the installation for standalone operation with the user panel and
Section 4.1.4 describes extended operation with external PLC signals. For control with
external signal connect the “USER INTERFACE” connector according to Figure 12 and Figure
13.
4. The pump system requires 48 VDC supply voltage at a maximum power of 300 W. Depending
on the hydraulic operational point power supplies with smaller power or bigger supplies to
supply several pump systems simultaneously may be used. Figure 7 shows the power
consumption depending on the pressure and flow rate. Contact Levitronix for consulting and
support on the power supply solution.
5. Connect the DC power supply connector with the cable (included in the controller delivery).
Make sure that the polarity is correct (see Figure 10 ) and that AC/DC power supply is off.
6. To secure the connectors, tighten all retaining screws according to the torque specification in
Table 7.

5 Operation
5.1 State Diagram of LPC-300.1
The controller LPC-300.1 allows stand-alone operation with manual speed setting (“Button Control Mode”) as
well as extended operation with analoge speed setting (Analoge Control Mode). Figure 14 shows the state
diagram which can be controlled with the manual buttons and the signals on the “USER INTERFACE”
connector. The operation mode can be choosen by pressing the “UP” and “DOWN” buttons simultaneously
during 5 seconds. For the standard firmware D2.25 default setting ex factory is “Button Control Mode”.

5.2 Standalone Operation (Button Control Mode)
▪When applying power the system defaults into the “Button Control Mode” and goes into the status “OFF
ButtonControl” according to Figure 14. Levitation is disabled and the display indicates “OF”.
▪Levitation can be enable by pressing the “UP” button during 1 second (display shortly indicates “ON”) or
by activating (typically 24V) the “ENABLE” pin on the “USER INTERFACE” connector (see Table 8). The
system goes then into the status “ON Button Control” and is running at the speed which is stored in the
EEPROM.
▪The speed can be changed by pressing accordingly the “UP” and “DOWN” buttons.
As long as the digits on the display are blinking the set speed is shown. As soon as blinking stops the
actual speed is shown and the set-speed is stored in the EEPROM of the controller after about 2
seconds.
▪The system can be disabled by pressing the “DOWN” button until 0 rpm is achieved. Pressing further 1
second the “DOWN” button the system disables levitation and shows “OF” on the display. The system
can also be disabled by deactivating (0 V) the “ENABLE” pin on the “USER INTERFACE” connector (see
Table 8). Before disabling the system the speed is automatically reduced to 0 rpm and the impeller is
properly touched down without grinding the wall.
▪In case of an error the “RESET” button (see Table 7) can be used to restart the system or the power can
be switch off and on. For more detailed error analysis the codes described in Table 9 are shown (blinking
between “Er” and the according code number) on the display.
Figure 15: User Panel of LPC-300.1
5.3 Extended Operation (“Analog Control Mode”)
▪In order to be able to control the pump with external signals (PLC) the mode “Analoge Control Mode” has
to be set with the display buttons. The “UP” and “Down” buttons have to be pressed simultaneously
during 5 seconds. The display should feedback the change by blinking between the stored speed value
and “An”. The chosen mode is then stored in the EEPROM of the controller.
▪The system and levitation can be enabled/disabled with the digital input on the “USER INTERFACE”
connector (see Table 8). When disabling the running system the speed is automatically reduced to 0 rpm
and the impeller is properly touched down without grinding the wall.
▪The speed can be set with an analoge signal on the “USER INTERFACE” connector according to Table
8. It is strongly recommended to use galvanic separated signal values
▪For monitoring purposes a digital output on the “USER INTERFACE” connector (see Table 8) indicates
an error. In case of an error the codes described in Table 9 are displayed (blinking between “An” and the
according code number)

6 Inspection and Maintenance
6.1 Replacement Interval of the Impeller
The impeller has a limited lifetime depending on the chemical type, concentration and temperature of the
fluid which is pumped. Therefore, a preventive periodical exchange of the impeller is recommended. Contact
the Levitronix Technical Service Department (see Section 8) for further information on replacement times.
6.2 Impeller Replacement Procedure
6.2.1 Preparation
Before starting the impeller replacement procedure
the parts and tools illustrated in Figure 16 and
Figure 17 should be prepared. Impeller exchange
kits, which contain this parts and tools are
available at Levitronix (see Table 2). Please verify
that you have the right types of impellers, O-rings
and screws.
Figure 16: Explosion view of pump head with motor
Figure 17: Components for impeller replacement
(The 4 M6x25 screws for motor mounting are not on the picture.)
The following warnings and cautions should be
read carefully before starting the replacement of
the impeller.
!
WARNING
The impeller could splash TOXIC or CORROSIVE
CHEMICALS because of the strong magnetic forces. Flush
the pump housing before opening it.
!
WARNING
HARMFUL CHEMICALS may be present.
Skin contact and toxic gases may be hazardous to
your health. Wear safety gloves and other appropriate
safety equipment.
!
CAUTION
The rotating impeller could cause injury. Do not run
the pump system when opening the pump head.
CAUTION
Pay attention to the magnetic forces when handling
the impeller. The attraction of magnetic parts and
particles should be avoided in order to keep the
impeller and the pump head clean and free of
contamination.

6.2.2 Instructions for Replacement
1. Power down the pump system and remove the
AC power. If necessary, allow the housing to
cool down to a workable temperature.
2. Unscrew the top of the pump head and remove
it along with the sealing ring.
3. Remove the impeller with the Impeller
Exchange Tool. Hook the claws of the Impeller
Exchange Tool into two opposing orifices of the
impeller.
4. Inspect the wet area of the pump head
carefully. In case of material damage, also
replace the pump casing.
5. Place the new impeller into the pump casing
using the Impeller Exchange Tool.
6. If necessary, remove the existing O-Ring and
gently press the new O-Ring into the lid of the
pump casing.
CAUTION
Use the correct O-Ring type for your process. If
necessary, consult the Levitronix Technical Ser-
vice Department.
Do NOT twist or roll the O-Ring as this may
cause leaking to occur.
7. Press the lid with the O-ring flush into the
bottom of the pump casing.
8. Carefully tighten the 8 PVDF screws. The
screws should not be used to press the lid with
the O-ring into the bottom of the pump casing.
Do not apply too much torque. The torque
specifications are:
Recommended torque for pump screws
PVDF M6: 50 Ncm
Note: These are typical values for the standard pump head
LPP-300.1. Refer to the relevant pump head specification
drawings for other configurations, which may have different
values.
9. Start up the system and check if the impeller is
rotating properly and the pump head doesn’t
leak.
10.If the pump head leaks, check and make sure
the lid and the O-Ring are properly pressed into
the bottom of the pump casing. It may be
necessary to change the O-Ring if it has been
damaged.
