CAUTION
The analog outputs of the PLC of the flowmeter need an insulated power source on
the user side, which is separated from the flowmeter supply. Non insulated power
sources may damage the sensor.

3.3 Instructions for Electrical Installation
1. Remove the DC power and all cables from the flowmeter before any installation work is done.
2. For operation with the user panel LUI-B.1 or with a PC attach the cables as shown in Figure 3 and
Figure 4.
3. For operation with the OEM cable ICS-2.2 or ICS-2.4, attach the necessary wires (AWG 14-26)
according to the pin specifications in Table 5. Strip the sheath approximately 3 mm from the wires
end. Insert core into the cable terminal to the end and tighten the screw. Confirm that the wires are
securely fixed by pulling it gently by hand.
4. Alternatively, the terminal of the ICS-2.2 or ICS-2.4 cable can be removed to assemble another
connector like wall-mountable circular connectors for cabinet mounting.
5. If another AC/DC power supply than the one offered by Levitronix
®
is used, than the specifications
in Table 5 shall be considered (voltage range, consumption current and start-up current).
6. For usage of a fuse at the power input a 200 mA slow-blow type is recommended considering the
inrush (start-up) current of the flowmeter (see Table 5).
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. 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 must be waited
after power-on.
9. 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. Section 4.1.3 explains the zeroing
possibilities.
10. The Levitronix
®
Service 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
