3.2 Hardware Error Burnout and Hardware Write Protect

Switch

There are two slide switches on the MAIN assembly board. One sets the hardware error burnout direction, and the other sets a hardware write protection function which disables parameter changes through the use of a handheld terminal or some other communication method.

The temperature transmitter is equipped with a hardware error burnout function used to set the output direction upon hardware error, and a sensor burnout function that sets the direction of the output in the event of burnout of the temperature sensor.

When factory-shipped under normal conditions, the output of both hardware error burnout and sensor burnout are set to HIGH, but if suffix code

/C1 is specified, the hardware error burnout is set to LOW (-5%) output, and sensor burnout is set to

LOW (-2.5%) output, respectively. The setting of the direction of output from burnout can be changed.

To change the direction of output arising from burnout, set the swich on the MAIN assembly (see

Figure 3.1 and Table 3.1). To change the direction of output arising out of sensor burnout, a dedicated hand-held terminal is required to rewrite the parameters within the transmitter.

NOTE

1. Turn off the power supply before changing the switches

2. To change the switches, it is necessary to remove the integral indicator assembly.

Refer to “ 6.3.1 Replacement of Integral

Indicator” about the procedures.

5.1 Notes on Wiring

IMPORTANT

• Apply a waterproofing sealant to the threads of the connection port. (It is recommended that you use non-hardening sealant made of silicon resin for waterproofing.)

• Lay wiring as far away as possible from electrical noise sources such as large transformers, motors and power supplies.

• Remove the wiring connection dust-caps before wiring.

• To prevent electrical noise, the signal cable and the power cable must not be housed in the same conduit.

• The terminal box cover is locked by an Allen head bolt (a shrouding bolt) on ATEX and

IECEx flameproof type transmitters.

When the shrouding bolt is driven clockwise by an Allen wrench, it is going in and cover lock is released, and then the cove can be opened by hands. See Subsection 6.3

5.3 Cable Selection

5.3.1 Input signal Cable Selection

A dedicated cable is used for connection between the temperature sensor and the temperature transmitter.

When a thermocouple is used as the temperature sensor, a compensation wire must be used that it appropriate for the type of thermocouple (refer to compensating cables for JIS C 1610/IEC60584-3 thermocouples). When a RTD is used as the temperature sensor, 2-core/3-core/4-core cable must be used (refer to JIS C 1604/IEC60751). The terminal of the dedicated cable is a 4 mm screw.

5.3.2 Output Signal Cable Selection

• With regard to the type of wire to be used for wiring, use twisted wires or cables with performance equivalent of 600V vinyl insulated cable (JIS C3307).

• For wiring in areas susceptible to electrical noise, use shielded wires.

• For wiring in high or low temperature areas, use wires or cables suitable for such temperatures.

• For use in an atmosphere where harmful gases or liquids, oil, or solvents are present, use wires or cables made of materials resistant to those substances.

• It is recommended that a self-sealing terminal with insulation sleeve (4-mm screw) be used for lead wire ends.

2. For DC voltage input

With a voltage generator, deliver input signals corresponding to 0, 25, 75, or 100% of the input span to the temperature transmitter. Measure the resulting input signal with the voltmeter

(digital multimeter) and check the output value relative to the input value.

3. For thermocouple input

Since this instrument is equipped with a reference junction compensating function, use a reference junction compensating function in universal calibrator in order to compensate for this function upon calibration. According to the reference millivolt table for thermocouple, obtain millivolt corresponding to 0, 25, 50, 75, or 100% of the span, and use that power as the input value, then deliver it from the universal calibrator to the temperature transmitter.

Measure the resulting output signal with the voltage meter (digital multimeter) and check the output value relative to the input value.

4. RTD

Using a RTD as input, calibration of the temperature transmitter is carried out via a

4-core wire connection.

As defined the reference resistor value table of the RTD, obtain resistance values corresponding to 0, 25, 50, 75 or 100% of the span, and use the obtained resistance as the input value, then deliver it to the temperature transmitter by means of a variable resistor.

Measure the resulting output signal with the voltmeter (digital multimeter) and check the output value relative to the input value.

5. In Steps 2 through 4, if the output signal deviates from the given range of accuracy when a given input signal is delivered, adjust the output using the handheld terminal. For details of how to adjust the output, refer to the additional reference, “HART Protocol” IM

01C50T01-02EN subsection 3.5.6 “Sensor

Trim” and the instruction manual for each terminal.

6.3 Disassembly and Assembly

This section details the procedure for part replacement or disassembly and assembly of each component depending on the maintenance process.

Precautions for ATEX and IECEx Flameproof

Type Transmitters

• For a withstand flameproof type transmitter, as a rule, move the transmitter to a nonhazardous location, then proceed with maintenance and restore the instrument to the original condition.

• For a withstand ATEX and IECEx flameproof type transmitter, turn the lock bolt (hexagon socket bolt) clockwise with a wrench for hexagon head, unlock and remove the cover.

When installing the cover, it is the must to turn the lock bolt counterclockwise and lock the cover (locked to a torque of 0.7 Nm).

• For a withstand flameproof type transmitter, in no case should the user be allowed to modify the transmitter. Therefore, no user is allowed to add a integral indicator, or use the transmitter with the indicator removed.

Contact us for any modification.

Note 1: Total Accuracy = (A/D Accuracy / Span + D/A Accuracy) or (± 0.1% of calibrated span), whichever is greater.

Accuracy of Fieldbus type: A/D Accuracy.

For T/C input, add Cold Junction Compensation Error (± 0.5°C) to the total accuracy.

Example: when selecting Pt100 with measurement range of 0 to 200 °C

0.1°C / 200°C×100% of span +0.02% of span = 0.07% of span

Since the value is smaller than ±0.1% of span, the total accuracy is ±0.1%.

Note 2: T/C C type is same as W5 (ASTM E988).

0.1Ω + 0.02% of reading

Note 1: The “abs.reading” for thermocouples and RTD means the absolute value of the reading in °C.

Example of “abs.reading”

When the temperature value is 250 Kelvin, “abs.reading” is 23.15.

|250−273.15|= 23.15

Note 2: Ambient Temperature Effect per 10 °C change is ±0.1% or ±(temperature coefficient/span), whichever is greater.

Example of Ambient Temperature Effect

Conditions:

1) Input Sensor: Pt100

2) Calibration Range: −100 to 100°C

3) Reading value: −50°C

Ambient Temperature Effect per 10°C

Temperature Coefficient/Span=(0.08°C+0.02/100×|−50°C|)/{100°C−(−100°C)}= 0.00045 → 0.045%

Therefore, Ambient Temperature Effect is ±0.1%/10°C
