2.4Installation Location Precautions

Please select the installation location considering the following items to ensure long term stable operation of the flowmeter.

•Ambient Temperature:

Please avoid to install the instrument at the location where temperature changes continuously. If the location receives radiant heat from the plant, provide heat insulation or improve ventilation.

•Atmospheric Condition:

Please avoid to install the instrument in an corrosive atmosphere. In case of installing in the corrosive atmosphere, please keep ventilating sufficiently and prevent rain from entering the conduit.

•Vibration or shock:

Please avoid to install the instrument at the location where there is heavy vibration or shock.

2.5 Cleaning Precautions

Care should be taken to prevent the buildup of dirt, dust or other material on the display glass. Such buildup may interfere with the operation of programming keys.

3.1Installing Magnetic Flow Converter

A signal cable (AM011) is used between the remote type flow tube and the converter. The maximum signal cable length is 300m (984ft).

The converter is mounted on a 2-inch (60.5mm outer dia.) vertical or horizontal pipe. See Figure 3.1.1

3.2 Wiring Precautions

This section is described wiring only for converter side. Please see «Wiring» in SE***DJ/EJ Magnetic Flow Tube User’s Manual for flow tube side.

NOTE

The terminal box cover is locked by special screw. In case of opening the terminal box cover, please use the Hexagonal Wrench attached.

CAUTION

Be sure to lock the cover with the special screw using the Hexagonal Wrench attached after tightening the terminal box cover.

The external signal wirings are connected into the terminal inside the converter. Please connect to each terminal (Please refer to Figure 3.2.1) by taking off a cover backside the converter.

3.2.1Protective Grounding

CAUTION

Please be sure to connect protective grounding of ADMAG SE with cable of 2mm2 or larger cross section in order to avoid the electrical shock to the operators and maintenance engineers and prevent the influence of external noise. And further connect the grounding wire to the mark (100Ω or less).

3.2.2General Precautions

Please give attention to the followings in wiring.

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

•When waterproof glands or 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. After tightening the covers, please be sure to fix it with the special screw using a hexagonal wrench attached.

•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.

3.2.3Cable Types

3.2.4DC Connections

(1)Connecting Power Supply

IMPORTANT

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

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.

(2)Setting Power Supply Frequency

IMPORTANT

In case of DC power supply, the frequency of the power supply has to be adjusted. Please adjust for the local power frequency. The power supply frequency is set in parameter B12 (or Power freq for HART). Refer to 5.4, 6.5.4, or

7.3.4for data setting procedure.

3.2.5Wiring Ports

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.

Figure 3.2.6 Waterproof Gland

(2)Conduit Wiring

In case of conduit wiring, please use the waterproof gland to prevent water flowing through the conduit pipe into the wiring connection.

Please slope the conduit pipe down, and install a drain valve at the low end of the vertical pipe.

Please open the drain valve regularly.

3.2.6Connecting to External Instruments

CAUTION

All the devices to be connected to current output and pulse output must be conformed to CSA1010, CSA950, or IEC950.

(1)Analog Signal Output(4 to 20mADC)

Figure 3.2.8 Connection for Analog Singal Output

(2)Pulse Output

IMPORTANT

Please give attention to voltage and polarity in wiring, because it is transister contact (insulation type.)

•In case of the filtering constant of Electric Counter is more than the pulse width, it makes signal decreases and can not be calculated correctly.

•In case of input impedance of electric counter is large inductive noise from power supply bring bad influence to measurement. To calculate correctly, it is recommended to use shield cable or to make input impedance small enough within the limits of pulse output of flowmeter.
