Select a storage location that ful ls the following conditions:
A place where it will not be exposed to rain or water
A place subject to minimal vibrations or shocks Temperature and humidity levels should be as follows:
Temperature:-40 to +80°C
Humidity:5 to 100% RH (no condensation) The preferred ambient temperature and humidity levels are +25°C and approximately 65% RH.
If the digitalYEWFLO vortex owmeter is transferred to the installation site and stored without being installed, its performance may be impaired due to the in ltration of rainwater and so forth. Be sure to install and wire the digitalYEWFLO vortex owmeter as soon as possible after transferring it to the installation location.
The vortex owmeter is a heavy instrument. Be careful that no damage is caused to personnel through accidentally dropping it, or by exerting excessive force on the vortex owmeter. When moving the vortex owmeter, always use a trolley and have at least two people carry it.

4. WIRING
IMPORTANT
For the descriptions of wiring for the Fieldbus Communication Type, read Chapter 11 “COMMUNICATION (FIELDBUS)”.
WARNING
The wiring of the vortex owmeter must
be performed by expert engineer or skilled personnel. No operator shall be permitted to perform procedures relating to wiring.
CAUTION
Once all wiring is complete, check the connections before applying power to the instrument. Improper arrangements or wiring may cause a unit malfunction or damage.
4.1 Load Resistance of Output Condition
Be sure to observe the following precautions when wiring:
CAUTION
• When the ambient temperature of the wire exceeds +60°C, use heat-resistant insulated wire with a maximum allowable temperature more than ambient temperature +30°C or above.
• Do not connect cables outdoors in wet weather in order to prevent damage from condensation and to protect the insulation.
• Do not splice the cable between the owtube terminal and the converter if it is too short. Replace the short cable with a cable that is the appropriate length.
• All the cable ends must be provided with round crimp-on terminals and be securely wired.
• Be sure to turn power off before opening the cover.
• Before turning the power on, tighten the cover securely.
• Explosion protected types must be wired in accordance with speci c requirement (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosion protected features.
• The terminal box cover is locked by the Locking Screw. In case of opening the terminal box cover, use the hexagonal wrench attached.
• Be sure to lock the cover by the Locking Screw using the hexagonal wrench attached after installing the cover.
Table 4.1 shows the connection method of several output conditions.
(1) Analog Output (4 to 20 mA DC)
This converter uses the same two wires for both, the signal and power supply. A DC power supply is required in a transmission loop.
The total leadwire resistance including the instrument load and power distributor (supplied by the user) must conform to a value in the permissible load resistance range. Read Figure 4.1.

PARAMETERS PARAMETERS


<7. COMMUNICATION (BRAIN / HART)> 30 7. COMMUNICATION (BRAIN / HART)
This chapter describes the operation procedures using a BRAIN TERMINAL (BT200). For details on the functions of the digitalYEWFLO, read Chapter 6 “PARAMETERS.” And also, read the “Model BT200 BRAIN TERMINAL” Instruction Manual (IM 01C00A11-01E) for more detailed Information.
7.1 Connection Method for the BT200
(1) Connecting the BT200 to a 4 to 20mA DC Transfer Line
The communication signal of the digitalYEWFLO is superimposed onto the 4 to 20mA DC analog signal to be transferred.
In case of general type (non-ex) and flameproof type: digitalYEWFLO
IMPORTANT
Communication signal is superimposed on analog output signal. It is recommended to
set a low-pass ter (approximately 0.1s) to the receiver in order to reduce the output effect from communication signal. Before online- communication, con rm that communication signal does not give effect on the upper system.
IMPORTANT
The communicable distance of the transmission line is restricted depending on the wiring method. Read Chapter 4 “WIRING.”
IMPORTANT
After setting a parameter, keep the power on for at least 30 seconds.
If the power of owmeter is turned off, a parameter setting is released.

8. OPERATION
After you have installed the owmeter into the process piping, wired the input/output terminals, set up the required parameters, the vortex owmeter should output an accurate ow signal from its terminals as soon as the measured liquid begins to ow.
This section describes procedure of test method and adjustment method for the pre-operation.
NOTE
The initial parameter setting has already been done at the factory according to the sizing data when ordering. Therefore it is not necessary to set parameters except measurement condition changes or some additions happen.
8.1 Adjustment 8.1.1 Zero Adjustment
No zero adjustment is necessary since the zero point does not shift.
Because of the effect of electrical noise and vibration noise, digitalYEWFLO may provide an output even when the owrate is zero. In that case, properly eliminate the source of the noise.
Read Section 8.2 “Adjustment for Manual Mode.”
8.1.2 Span Adjustment
In normal application, you need not con rm the span.
If you need to ensure the output of 4 to 20mA DC, read Subsection 8.1.3 “Loop Test.”
8.1.3 Loop Test
To ensure output of 4 to 20mA DC or pulse, their loop tests can be done using parameter “J10 (Analog out)” or “J20 (Pulse test)”.
If you are verifying the analog output, follow the procedure on the veri cation procedure. <Check Procedure>
1. Connect the instruments by reading Figure 8.1, and warm up for three minutes more.
2. Set span frequency in Parameter J10:OUT ANALOG.
3. In case the load resistance is 250Ω, digital multimeter indicates 5V. Otherwise if it is known load resistance value, it indicates R (Ω) × 0.02 (A).
4. Check output value is in the rated value (±0.016 mA) after set 50% in Parameter J10.
5. Check output value is in the rated value (±0.016 mA) after set 0% in Parameter J10.
250Ω
Figure 8.1
IMPORTANT
• When using any test-purpose measuring instruments, do not ground them.
• All of your parameter settings will be cancelled if you turn digitalYEWFLO off less than 30 seconds after the parameter setup. Keep digitalYEWFLO turned on at least 30 seconds after setting up the parameters.
NOTE
When con gure the parameters using the HART Con guration Tool, read IM 01F06A00- 01EN Section 8.11 “Menu Tree (HART 5)” or IM 01F06A00-01EN Section 9.11 “Menu Tree (HART 7).”

OPERATION OPERATION


8.1.7 Setting of Write Protect Switch
By setting the write protect function to “Protect”, it is possible to prevent the overwriting of parameters. Write protection can be carried out using either the hardware switch on the CPU board (i.e., Switch
2) or software parameter settings. If either of these items is set to “Protect”, the overwriting of parameters will be prohibited.
<8. OPERATION> 34 8.2 Adjustment for Manual Mode
digitalYEWFLO does not need the initial adjustment because digitalYEWFLO is always adjusted by itself automatically.
These adjustments should be done in case that indicator reads over zero at zero ow.
8.2.1 Low Cut Adjustment
Adjust to noise elimination or zero ow in the low NOTE owrate (or low frequency) range.
If the hardware switch is set to “Protect”, it will not be possible to overwrite parameters; furthermore, this condition will be maintained until the switch is set to “Enable”.
For more details regarding usage of the write protect function and the software’s parameter switches, read IM 01F06A00-01EN Section 8.9 “Software Write Protect” or IM 01F06A00-01EN Section 9.9 “Software Write Protect.”
