1 Safety Precautions
CAUTION
Do not under any circumstances open the converter or sensor housing.
Levitronix does not assume responsibility for any damage, which
occurs under such circumstances.
!
WARNING
Hazardous voltage may be present.
In case of the usage of an inadequate AC/DC power supply, mains
voltages may be present (even if the system is designed for 24VDC).
The converter must be placed in a spill protected environment. Do not
under any circumstances open the powered converter.
The usage of galvanic separated AC/DC supply is highly recom-
mended (preferable with UL 1950, UL 508C and/or IEC/EN60950).
!
WARNING
TOXIC CHEMICALS may be present.
When using the flowmeter to measure chemicals skin contact and toxic
gases may be hazardous to your health. Wear safety gloves and other
appropriate safety equipment.

3.1.2 Instructions for Electrical Installation
1. Remove the DC power from the converter.
2. Remove the interface connector (see Figure 11a) from the converter.
3. Attach the necessary wires (AWG 14-26) according to the pin specifications in Table 9. Strip the
sheath approximately 3 mm from the wires end. Insert core into terminal to the end and tighten the
screw. Confirm that the wires are securely fixed by pulling it gently by hand.
4. Note: The Field Ground (FG) represents an additional ground potential, which is connected internally
to the signal ports of the converter via varistors. Depending on the specific setup, it might be
advantageous from an EMC perspective to connect the FG to the PE. However, in case the FG is
connected to PE the entire grounding concept of the field installation must be considered in order to
avoid stray and compensating currents triggered by electrical potential differences. If compensating
currents between PE and Ground may occur, the FG should not be connected.
5. For usage of a fuse at the power input (24 VDC) a 200 mA slow-blow type is recommended. The
peak current (inrush current) after power on of the converter (as specified in Table 9) has to be
considered, when choosing the fuse type and the AC/DC power supply.
6. Mount the interface connector to the converter and tighten the 2 connector screws.
7. To attach the sensor to the converter extension cables according to Table 3 can be used. To
increase robustness against disturbance from other devices or to reduce cross-talking between
multiple flowmeters, the converter comes delivered with an EMI ferrite, which shall be attached to the
sensor cable near to the converter (see Figure 12):
Figure 12: Assembly of EMI ferrite
8. Before powering on check again all wiring connections. Confirm that the terminals are securely
fastened and that there is no possibility of short circuit.

4. For connecting the sensor to the wall-mountable connector on the cabinet the interconnect cable according to
Table 3 and Figure 7 can be used.
Step 1: Align first the Snap-Pin side of the converter
with the DIN rail corner (picture a). If the rigid
side is aligned first (see picture b) than some of
the DIN rail parts of the converter housing might
be damaged.
Step 2: Press in the converter on the spring-pin side
(see picture c).
Step 3: Press in the fix side of the DIN rail recess of the
converter housing (see picture d)

1. Remove the DC power supply from the converter.
2. Remove the interface connector on the connector box (see Figure 14).
3. Attach the necessary wires (AWG 14-26) according to the pin specifications in Table 10, Table 11 or Table 12.
Strip the sheath approximately 3mm from the wires end. Insert the core into the connector up to the end and
tighten the screw. Confirm that the wires are securely fixed by pulling it by hand.
4. Note: The Field Ground (FG) represents an additional ground potential, which is connected internally to the
signal ports of the converter via varistors. Depending on the specific setup, it might be advantageous from an
EMC perspective to connect the FG to the PE (protective earth). However, in case the FG is connected to PE
the entire grounding concept of the field installation shall be considered in order to avoid stray and
compensating currents triggered by electrical potential differences. If compensating currents between PE and
Ground may occur, the FG should not be connected.
5. For usage of a fuse at the power input slow-blow type with a current rating of the converters (see Table 7) and
25% additional margin is recommended. Consider the inrush current of the converters (see Table 7) during
power start-up, when choosing the fuse type and the AC/DC power supply.
6. Mount the bus connector to the converter and tighten the 2 connector screws.
7. Before powering on, check again all wiring connections. Confirm that the terminals are securely fastened and
that there is no possibility of short circuit.
8. For proper EMI behavior of the LFC-6CIO-PC a ferrite is needed. This can be ordered according to Table 3
and assembled according to Figure 15. All bus wires shall be covered and the ferrite shall be placed at a
distance not longer than 15 cm from the connector box of the converter (see also Figure 8).
Figure 15: Mounting of EMI ferrite for bus wires of LFC-6CIO-PC (See Table 3 for order information)
9. If multiple LFC-6CIO-PC are stacked as illustrated in Figure 14, every sensor cable shall be configured with a
ferrite according to Figure 16 (see Table 3 for order information) in order to avoid cross talking of the sensor
signals. The ferrites shall be placed as near as possible to the beginning of the sensor cable (near to the
plastic connector).

3.3 Installation of Sensors
3.3.1 Overview and Preparation
Figure 17: Clamp-on flow sensor model LFSC-xxD
1. Every sensor comes delivered with a calibration sheet. Check if the S/N on the calibration
sheet corresponds to the S/N on the type label of the sensor.
2. Please store the delivered calibration sheet or its data on a defined storage place in order to
be able to refer to it in case of problems.
3.3.2 Instructions for Electrical Installation
1. Attach one of the extension cables (see Table 3) coming from the converter to the sensor
connector.
2. When applying power, the controller needs about 10 seconds for a start-up procedure to be
ready. In order to get stable temperature and signals for converter and sensor 30 minutes
shall be waited after power-on.
3. After start-up a Zeroing is recommended. Assure that the sensor is filled completely with the
according fluid, free of bubbles and that zero flow is realized. Then push the “ZERO ADJ”
button on the converters for about 3 seconds. During adjustment “0ADJ” appears on the
converter display (about 2 seconds with blinking). The zero adjustment procedure will take
about 26-60 seconds.

3.3.3 Mechanical and Hydraulic Installation
1. In order to mechanically fix the sensor body, 2 fixation threads on the backside of the sensor
housing can be used (see Figure 6).
2. Assure that at the mounting location, the allowed ambient temperature range (Table 5) is not
exceeded.
3. Clamp the sensor to the tubing according to the procedure described in Section 3.3.4. Use only
tubing material for the specified calibration (see calibration sheet).
4. The flow circuit should be filled completely with fluid. The converter DSP (Digital Signal Processor)
contains special algorithms, which increase the robustness of the measurement against bubbles.
However, assure that excessive bubbles are avoided in the circuit.
5. Ideal mounting position for the flow sensor is a slight angle with upward flow direction to avoid the
stagnation of bubbles and particles in the measuring path of the tubing.
6. An arrow mark on the flow sensor (see Figure 17) indicates the flow direction. Make sure that the
arrow corresponds to the direction of the flow in the hydraulic circuit.
7. Avoid excessive vibrations such as in the vicinity of displacement pumps. Vibrations might
influence the flow measurement. If vibrations sources can not be avoided, acoustic decoupling
technics between flowmeter and vibration source shall be considered.
8. The flowmeter measures flow velocity. In order to obtain fully developed flow pattern for accurate
velocity measurement, straight run of 30x tubing ID upstream and of 12x tubing ID downstream is
recommended (see Table 5 for ID specifications of the sensor models). If non-uniform turbulent
flow or swirl flow is expected, install longer upstream straight run and/or a flow-rectifier.
9. To install on a tubing that has open end, the sensor should be mounted in lower position of the
pipeline.
10. The sensor should be mounted where pressure in the pipe is above the atmospheric pressure in
order to avoid bubble generation by cavitation effects.
11. Devices like valves are recommended to be installed downstream of the sensor in order to prevent
formation of bubbles in the liquid. An upstream valve may form bubbles reducing the intensity of
the ultrasound signal and interfering with measurement.
12. A bypass pipe run (including bypass valve and shutoff valve) may be used for easy zero
adjustment and maintenance.
13. Please confirm that the maximum pressure is below the maximum pressure of the flexible tubing
and the maximum pressure of the sensor specified in Table 5.
14. After setup a “Zeroing”is recommended. Assure that the sensor is filled completely with the
according fluid and is free of bubbles. Stable liquid properties should be assured by flushing the
circuit with the final liquid until temperature and viscosity becomes stable. After this, zero flow shall
be realized. Then push the “ZERO ADJ” button on the converters for about 3 seconds. During
adjustment “0ADJ” appears on the converter display (about 2s with blinking). The duration of
zeroing is about 26-60 seconds.
15. If Re-Zeroing is regularly necessary, automation is possible over the digital input of the converter.
For the configuration of the digital input the Levitronix®Service Software is needed. Consult the
manual of the service software for more detailed description.
16. In the following cases a re-zero is recommended:
a. 30 minutes after power-on of a cool converter and sensor
b. Change of fluid properties (temperature, viscosity, density)
c. Change of chemistry
d. Clamp-on of the sensor to a new tubing
e. Change of the hydraulic circuit
