3.2 Setting the Hardware Error Burnout Change-over Switch 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.
For a list of error codes, refer to “Error code table” in Section 6.4. (6) Unit display The unit specified as the unit of process in the process variable display column in Item (5) is lit. The output display is fixed to mA or %.

In the event of hardware error, “FAIL” is displayed. <3.
<4. Installation> 4. 4-1 Installation IMPORTANT • When performing on-site pipe fitting work that involves welding, use care to prevent outflow of the welding current into the transmitter. • Do not use the transmitter as a foothold for installation. Horizontal Pipe Mounting • For details of choosing the installation location, refer to the guidelines outlined in Section 2.4, “Choosing the installation location”. • The mounting bracket shown in Figure 4.
5. 5-1 <5. Wiring> Wiring 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.
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/IEC584-3 thermocouples). When a resistance temperature sensor (RTD) is used as the temperature sensor, 2-core/3-core/4-core cable must be used (refer to resistance thermometer sensor JIS C 1604/ IEC751). The terminal of the dedicated cable is a 4 mm screw. 5-2 <5.

5.5 <5. Wiring> Wiring Cautions (1) General-use Type and Intrinsically Safe Type Use metal conduit wiring or a waterproof gland (metal wiring conduit JIS F 8801) for cable wiring. • Apply nonhardening sealant to the threads of the wiring tap and a flexible fitting for secure waterproofing. Figure 5.10 shows an example of wiring on the output side. This example also applies to the wiring on the input side.

Follow the domestic electrical requirements as regulated in each country. For a transmitter with built-in lightning protector, grounding should satisfy ground resistance of 10Ω or less.
6. 6-1 <6. Maintenance> Maintenance 6.1 General Each component of this instrument is configured in units to make maintenance easier. This chapter contains disassembly and assembly procedures associated with calibration, adjustment and part replacement required for maintenance of the affected instrument. IMPORTANT 1. Maintenance of this instrument should be performed in a service shop where the necessary tools are provided. 2.
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 milivolt table for thermocouple, obtain milivolt 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.
6-3 <6. Maintenance> 6.3.1 Replacement of Built-in Indicator 6.3.2 Replacement of CPU Assembly Removal of built-in indicator Removal of CPU assembly 1. Remove the cover. 2. Loosen two mounting screws while using your hand to support the built-in indicator. 3. Remove the LCD assembly from the CPU assembly. At this time, straighten and pull the LCD assembly forward so that the connector connecting the CPU assembly and the LCD assembly is not damaged. 1. Remove the cover. 2.
