IM 1E7C1-E

3. INSTALLATION

NOTE

CAUTION

• Please pay attention to avoid the cable is bended excessively.

• Please do not connect cables outdoors in case of rain to prevent damages from dew formation and to keep insulation inside the terminal box of the flowmeter.

• The all cable ends are to be provided with round crimp-on terminal.

•The power cables and signal cables must be routed in separate steel conduit tubes or flexible tubes.(except 4-core 24VDC cable wiring.)

• When waterproof glands, union equipped waterproof glands are used, the glands must be properly tightened to keep the box watertight.

•Please install a external switch or circuit breaker as a means of power off (capacitance; 15A, conform to IEC947-1 and IEC947-3). The preferable location is either near the instrument or other places to easy operation. Furthermore, please indicate "power off equipment" on the those external switch or circuit breaker.

•Please be sure to fully tighten the terminal box cover before the power is turned on.

•Please be sure to turn off the power before opening the terminal box cover.

• In case of DC power supply, a plug is attached. When 4-core cable is used, please put that plug into unused electrical connection port.

3.2.3 Cable Types

(1) Dedicated Signal Cable(AM011)

The flow signal is transmitted via this dedicated cable. The cable is constructed with double shielding over the two conductors, and used heat-resistant vinyl as the outer jacket material.

IMPORTANT

If the cable is longer than required, cut off any extra length, rather coiling it up, and terminate the conductors as shown in Figure 3.2.3. Avoid using intermediate terminal boards to extend the cable length, or this will interrupt the shielding.

Figure 3.2.2 Dedicated Signal Cable AM011

Conductors A and B carry the signal from the electrodes, and C is at the potentials of the liquid it self (signal common) . Shields SA and SB are kept at the same potentials as the individual electrodes (these are actively driven shields). This is done to reduce the effect of the distributed capacitance of the cable at long cable length. Note that, since the signals from the individual electrodes are impedance converted inside the converter, errors will result if they come in contact with any other component. Great care must be taken in the cable end treatment.

IMPORTANT

In case of 24VDC power supply, AC power supplies or reversed polarities cannot be connected. It will cause the fuse to burn out.

(2)Supplied Voltage Rating for 24VDC

IMPORTANT

In case of 24VDC power supply, the specification for the supply voltage is 24VDC (-15 to +20%), but the input voltage of the converter drops due to cable resistance so it should be used within the following range.

Please select the most suitable standard of wiring procedure for the wiring ports by customer’s own.

(1)Using the Waterproof Gland

IMPORTANT

To prevent water or condensate from entering the converter housing, waterproof glands are recommended. Do not over-tighten the glands or damage to the cables may result. Tightness of the gland can be checked by confirming that the cable is held firmly in place.

5. FUNCTION AND DATA SETTINGS

A magnetic flowmeter calculates volume flow rate from minute voltage that corresponds to the flow velocity of a fluid and outputs a 4 to 20mA signal.

The three parameters must be set to obtain a correct signal. Nominal size, flow span and

NOTE

meter factor must be set. This chapter explains how to set flow span and other functions. Please set data correctly.

You cannot set the leftmost digit of display to numeric value greater than "4". If the leftmost digit of the span must be "4" or more, set the numeric value beginning from the digit second from the left on the display (the fourth digit). If the leftmost digit of the display is set to "3", the digits to its right can be set to "0" only , regardless of the decimal point position.

5.2 Setting Flow Span

(1) Determining the Flow Rate Span Value

The flow rate span is the instantaneous flow rate value at which the output current is to be 20 mA.

Please determine the span under considering the followings.

• Please set the maximum flow rate at the most variable flow rate line. If the flow rate of the fluid exceeds the flow rate span value, the flow rate that exceeds this value (20mA or more) is not output and the meter will not display the correct flow rate (108% or more cannot be output).

• In a line where the flow rate is comparatively stable, set a value that is 1.5 to 2.0 times larger than the normal flow rate.

• Set a value that will correspond to a flow velocity of 0.3 to 10m/s.

The flow velocity is checked using sizing data or parameter number "13". (Parameter

number "13" displays the set span in flow velocity values.)

• The display of data is based on the input flow rate span value. It is recommended that the accuracy of the first digit is in a 0.05 to 0.1%. For example, 30 m3/h should be set as 30.00m3/h.

• The maximum numeric value that can be set is "30000" except any relation with decimal position.
