警告!
在盖子尚未安装到位的情况下运行传感器会产生触电危险,进而导致死亡、伤害或财产损失。 确保用于现场接线的安全栅隔离和保护盖、以及电路板所在腔体、电子元件模块及外壳在处 理器通电之前全都安装到位。
5.2
警告!
若在危险区域使用服务端口进行通讯,则可能引起爆炸。在危险区域使用服务端口与核心处 理器通讯之前,确保周围气体中不含有爆炸性气体。
打开供电电源。传感器将自动执行诊断例程。传感器通电程序结束后,核心处理器
2.
将在贸易交接安全模式下工作,不会产生报警。
随后,传感器即可在通电大约一分钟(这个时间因具体型号而异)之后开始接收过程介质。 但电子元件要预热到平衡状态,则需要大约十分钟。在这十分钟内,处理器可能稍微有点不 稳定或不准确。

Quick Start Guide 1
Installation checklist
Make sure that the hazardous area specified on the approval tag is suitable for the environment in which the LNG meters will be installed.
Planning
Verify that the local ambient and process temperatures are within the limits of the LNG meters.
Verify that you are using low-voltage DC power for the core processor. Excess voltage can damage the core processor.
For I.S. applications, refer to Micro Motion ATEX, UL, or CSA installation instructions.
Mount the LNG electronics in any orientation as long as the conduit openings do not point upward.
CAUTION!
Upward-facing conduit openings risk condensation entering the housing that can damage the electronics.
Install the sensors so that the flow direction arrow on the case matches the actual forward flow of the process. (Flow direction is also software-selectable.)

3.1 Wire the core processor to the sensor
3.1.1 Wire the core processor to the sensor using jacketed cable
Prerequisites
For hazardous area installations, install the jacketed cable inside a user-supplied sealed metallic conduit that provides 360° termination shielding for the enclosed cable.
CAUTION!
Sensor wiring is intrinsically safe. To keep sensor wiring intrinsically safe, keep the
sensor wiring separated from power supply wiring and output wiring.
Keep cable away from devices such as transformers, motors, and power lines, which
produce large magnetic fields. Improper installation of cable, cable gland, or conduit could cause inaccurate measurements or flow meter failure.
Improperly-sealed housings can expose electronics to moisture, which can cause
measurement error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.
Procedure
1. Run the cable through the conduit.
2. At the core processor, insert the stripped end of each wire into the corresponding
terminal at the core processor ends, matching by color. No bare wires should remain exposed. See the following table.

Wire the core processor to the sensor using shielded cable
Prerequisites
For hazardous area installations, shielded cable must be installed with cable glands at the core processor end. Cable glands that meet hazardous area requirements can be purchased from Micro Motion. Cable glands from other vendors can be used.
CAUTION!
Sensor wiring is intrinsically safe. To keep sensor wiring intrinsically safe, keep the
sensor wiring separated from power supply wiring and output wiring.
Keep cable away from devices such as transformers, motors, and power lines, which
produce large magnetic fields. Improper installation of cable, cable gland, or conduit could cause inaccurate measurements or flow meter failure.
Improperly-sealed housings can expose electronics to moisture, which can cause
measurement error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.
Procedure
1. Identify the components of the cable gland and cable.

2. Unscrew the nipple from the compression nut.
3. Screw the nipple into the conduit opening for the 9-wire cable. Tighten it to one turn
past hand-tight.
4. Slide the compression ring, compression nut, and sealing nut onto the cable. Make
sure the compression ring is oriented so the taper will mate properly with the tapered end of the nipple.
5. Pass the cable end through the nipple so the braided shield slides over the tapered
end of the nipple.
6. Slide the compression ring over the braided shield.
7. Screw the compression nut onto the nipple. Tighten the sealing nut and
compression nut by hand to ensure that the compression ring traps the braided shield.
8. Use a 25-mm (1-inch) wrench to tighten the sealing nut and compression nut to
20–25 foot-pounds (27–34 N-m) of torque.

Grounding
4 Grounding
Topics covered in this chapter:
Ground a dual core processor
Ground the enhanced core processor
The meter must be grounded according to the standards that are applicable at the site. The customer is responsible for knowing and complying with all applicable standards.
Micro Motion suggests the following guides for grounding practices:
Use copper wire, 2,0 mm2 or larger wire size.
Keep all ground leads as short as possible, less than 1 Ω impedance.
Connect ground leads directly to earth, or follow plant standards.
4.1 Ground a dual core processor
Use this procedure if your installation contains a dual core processor.
Note
Ground the processor to earth, or follow ground network requirements for the facility. Improper grounding can cause measurement error.
Procedure
If the joints in the pipeline are not grounded, connect a ground wire to the internal or external grounding screw located on the dual core processor.

Topics covered in this chapter:
Power on
Sensor start up checklist
Specifications
5.1 Power on
1. Before you apply power to the sensors, close and tighten all housing covers.
WARNING!
Operating the sensor without covers in place creates electrical hazards that can cause death, injury, or property damage. Make sure safety barrier partition and covers for the field-wiring, circuit board compartments, electronics module, and housing are all in place before applying power to the processor.
Basic configuration
5.2
WARNING!
Using the service port to communicate in a hazardous area can cause an explosion. Before using the service port to communicate with the core processor in a hazardous area, make sure the atmosphere is free from explosive gases.
2. Turn on the electrical power at the power supply. The sensors will automatically
perform diagnostic routines. When the sensors have completed their power-up sequence, the core processor should work in custody transfer secure mode without alarms.
Note
The sensor is ready to receive process fluid approximately one minute after power-up (time varies with models). However, approximately ten minutes are required for the electronics to warm up to equilibrium. During this ten-minute period, the processor may exhibit minor instability or inaccuracy.
