1. Check if the
Sensor S/N
(serial number) and the
Sensor Type
on the sensor specific label on the
) corresponds to the data of the used sensor. If no sensor
specific label is applied on the converter the
LEVIFLOW
®
Configuration Software
(see
Section 4.4
has to be used to load the sensor specific calibration data (available on the sensor tag, see
) to the converter. Consult the configuration
“
Configuration-SW User Manual
” (
Levitronix
Doc.#
PL-4501-00
) for handling with the
LEVIFLOW
®
configuration software
Note: If the converter and the flow sensor are ordered and delivered as a set (see Table 4), the
sensor specific data is already stored in the converter and the according label is applied on the
converter back side.
2.
If communication over the RS485 bus is used, check the address settings of the potentiometers on
the front panel of the converter (see
). The total address is:
“High ADRS” x 10 + “Low ADRS” x 1
3. The
LEVIFLOW
®
Configuration Software
can be used to debug and configure the flowmeter over
the RS485. For communication with RS485 the MODBUS protocol can be requested at
Levitronix
.
3.1.2 Instructions for Electrical Installation
1. Remove the DC power from the converter.
2. Remove the interface connector (see
) from the converter
3. Attach the necessary wires (AWG 14-26) according to the pin specifications in
. Strip the
sheath approximately 3mm 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 has to 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 after power on of the converter is 4.4 A during 2 ms, which 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.
Attach the SMB connectors of the sensor extension cable and assure the “IN” and “OUT” labels
of the converter fit with the labels of the extension cable.
8. Do not pull directly on the cable when disconnecting it from the converter. Use the end of the
SMB connector to pull it.
9. Before powering on check again all wiring connections. Confirm that the terminals are securely
fastened and that there is no possibility of short circuit.
3.1.3 Configuration of Sensor Specific Data
If the single channel converters are ordered in a package with the sensor (see
) the converter comes
configured with the sensor specific data included the calibration data. If converter and sensor are ordered
separately the
K-Factor
and the
Calibration Values
of each sensor have to be stored to the converter with the
LEVIFLOW
®
configuration software. The
K-Factor
and the
5 Calibration Values
(
5 calibration and 6 linearizer
values
for
LFS-008
) are available on the sensor tag and on a calibration sheet delivered with each sensor.
Consult the configuration “
Configuration-SW User Manual
” (
Levitronix
Doc.#
PL-4501-00
) for handling with
the
LEVIFLOW
®
configuration software.
Note: The LFS-008 sensor with converter LFC-1C-F4 needs configuration software version V1.18 or higher.
The LFC-6CIO needs configuration software version V1.25 or higher.
