The output terminals can be connected to co-operating electronic equipment using standard shielded signal
cables of external diameter 3 to 6.5mm and conductor cross-section 0.5 to 1.5mm
2
. Shielded conductors
shall also be used to connect all output signals and the communication line where the shielding shall be
connected to the earth potential on the side of the master control system.
Upon connecting the conductors to the terminals, tighten the bolts holding the transmitter housing cover and
check the gland sealing. The unused glands shall be blinded.
6.3. Interconnection of sensor and transmitter (remote version)
In the compact version of meter, the connection is internal. In the remote version, the transmitter shall be
connected to the sensor be means of a special cable attached to the transmitter. On the sensor side,
connect the cable wires paying attention to the wire insulation colours and the terminal identification labels.
Special cable UNITRONIC Cy PiDy 3x2x0.25 length up to 50 m, temperature up to 70 °C (158 °F):
6.4. Interconnection of sensor and transmitter (remote version with IP 68)
In the IP 68 version of the flow sensor, the terminal box is sealed by cast plastic and the connecting cable is
fixed on the sensor side. On the transmitter side, the cable is provided with a screw-on connector with its
mating part mounted on the transmitter bracket. To prevent unauthorised handling, this connector can be
sealed. The hole for the seal wire is provided in the bracket.
6.5. Commissioning
6.5.1. The ECONOMIC version
The electromagnetic flowmeter of either compact or remote design must first be fitted mechanically and then
the power supply and output terminals be interconnected. Then switch on the supply voltage. Within a short
time, the meter will be initialized and its operational conditions stabilised. Information on the liquid flow
parameters will start to be communicated from the meter outputs to the co-operating equipment (the plant
control system) equipment.
The ECONOMIC version of the meter does not include any keypad or display unit. The meter configuration is
always customized. Changes in the configuration and/or setting can be performed via the USB serial
communication line using a computer with the FLOSET 2.0 software supplied by ELIS PLZEŇ a. s.
6.5.2. The COMFORT version
The electromagnetic flowmeter in compact or remote design must first installed in the piping and then the
power supply and output terminals be interconnected. Then switch on the power supply voltage. For a while,
the meter display will show a welcome message. Then the measured flow rate values will appear on the
display.
