Description

5Description

5.1Area of application

The transmitter 8025 Universal can be connected to a remote flow sensor which emits a frequency signal. The specifications of the flow sensor which can be connected to the transmitter are described in chapter „6 Technical data“.

When connected to a flow sensor, the device makes it possible to switch a solenoid valve, activate an alarm or generate a flow rate proportional frequency, thanks to a transistor output and, for some versions, by means of two relay outputs, fully configurable, and to establish a control loop thanks to a 4-20 mA current output.

Respect standard NF C 15-100 / IEC 60364.

Risk of injury due to unintentional switch on of power supply or uncontrolled restarting of the installation.

Take appropriate measures to avoid unintentional activation of the installation.

Guarantee a set or controlled restarting of the process subsequent to any intervention on the device.

Type 8025 UNIVERSAL

Installation and wiring

Insert the supplied stopper gaskets into the unused cable glands of a wall-mounted version to ensure the tightness of the device.

Only move the selectors when the power supply is off.

• Use a filtered and regulated 12-36 V DC power supply.

• Make sure the installation is equipotential. See chap. „7.4.1“.

•Use shielded cables with a temperature limit of 80 °C minimum.

•Do not install the cables near high voltage or high frequency cables; If this cannot be avoided, observe a min. distance of 30 cm.

•Protect the device power supply by means of a 300 mA fuse and a switch.

•Protect the power supply of each transistor output by means of a 125 mA fuse.

•Protect the relays by means of a max. 3 A fuse and a circuit breaker (depending on the process).

•Do not apply both a dangerous voltage and a safety extralow voltage to the relays.

7.4.1Equipotentiality of the installation

To ensure the equipotentiality of the installation (power supply - device - fluid):

→→Connect together the various earth spots in the installation to eliminate the potential differences that may occur between different earthes.

→→Observe faultless earthing of the shield of the power supply cable, at both ends.

→→Connect the negative power supply terminal to the earth to suppress the effects of common mode currents. If this connection cannot be made directly, a 100 nF/50 V capacitor can be fitted between the negative power supply terminal and the earth.

→→Special attention has to be paid if the device is installed on plastic pipes because there is no direct earthing possible. Proper earthing is performed by earthing together the metallic instruments such as pumps or valves, that are as close as possible to the device. If no such instrument is near the device, insert metallic earth rings inside the plastic pipes upstream and downstream the device and connect these parts to the same earth. The earthing rings must be in contact with the fluid.

Before connecting the flow sensor to the transmitter 8025 UNIVERSAL:

•set selector "SENSOR TYPE" depending on the output signal providing from the flow sensor. See „Fig. 25“ and „Tab. 1“ page 29.

•if the selector "SENSOR TYPE" is set on "NPN/PNP", set the selector "SENSOR SUPPLY" depending on the transmitter supply voltage. See „Fig. 26“.

•set selector "LOAD" depending on the type of signal sent out by the flow sensor and on the load wanted on terminal 1 "PULSE INPUT" of terminal block "FLOW SENSOR".

See „Tab. 1“ page 29.

Installation and wiring

Selector D makes it possible to configure the type of signal the 8025 Universal receives from the flow sensor.

D

SENSOR TYPE

COILNPN/PNP

→→Set the selector on the right (default position) when the signal from the flow sensor which is connected to the 8025 Universal is either:

•a pulse signal, NPN or PNP

•an "on/off" signal (Reed relay for example)

•a 0-5 V DC standard voltage signal (TTL, for example)

SENSOR TYPE

COILNPN/PNP

→→Set the selector on the left when the signal from the flow sensor which is connected to the 8025 Universal is a sine-wave signal (coil).

Fig. 25: Using selector "SENSOR TYPE"

When selector "SENSOR TYPE" above is set on "NPN/PNP",

selector B makes it possible to configure the supply voltage for the flow sensor.

→→If the 8025 Universal is energized with a 115/230 V AC power supply, set selector "SENSOR SUPPLY" on "L+" (default position).

→→If the 8025 Universal is energized with a 12-36 V DC power supply, set the voltage selector "SENSOR SUPPLY" depending on the voltage supply needed by the remote flow sensor: "+5V", "L+" or "(L+)-12V" (default position).
