Installation

Select an appropriate location for the transmitter, ensuring the following: Access to the process connection Sufficient clearance for maintenance Protection from extreme heat, vibration, and moisture Install the transmitter using the appropriate mounting bracket. Connect the process fluid to the appropriate inlet and outlet ports. Connect the electrical wiring to the transmitter terminals. Apply power to the transmitter and verify its operation.

Configuration

The transmitter can be configured using the following methods:

Local Configuration Menu: Access the factory-set parameter menu using the built-in display and navigation buttons. Remote Configuration Software: Install the designated software on a computer and connect to the transmitter via the communication interface. HART Protocol: Utilize a HART-compatible communicator to access and modify transmitter parameters.

Typical configurable parameters include:

Measurement Range Output Scale Damping Trip Points Simulation Mode

Operation

The transmitter is designed for continuous operation and can be used with a variety of liquids, including water, oils, and chemicals. The level measurement is determined by the capacitance change between the transmitter probe and the liquid surface. This change is converted into a 4-20 mA output signal that is proportional to the level.

The transmitter can be operated in different modes:

Continuous Mode: Outputs a 4-20 mA signal corresponding to the current level. Simulation Mode: Outputs a predetermined 4-20 mA signal for testing or calibration purposes.

Maintenance

Regular maintenance is essential to ensure optimal performance of the transmitter.

Visual Inspection: Regularly inspect the transmitter for any physical damage or corrosion. Electrical Connections: Ensure that all electrical connections are secure and free of corrosion. Process Fluid Compatibility: Verify that the process fluid is compatible with the wetted materials of the transmitter. Calibration: Regularly calibrate the transmitter to maintain accuracy and minimize drift.

Troubleshooting

In the event of a problem, refer to the following table for troubleshooting steps:

Problem Cause Solution No output signal Power supply failure Check power connections and ensure power is supplied. Output signal incorrect Incorrect configuration Verify measurement range, output scale, and other settings. Fluctuating output signal Excessive vibration or turbulence Isolate the transmitter from vibrations or damp the output signal. Transmitter not responding Communication failure Check communication settings and connections, including baud rate and parity.

Compliance and Certification

The transmitter meets the following industry standards and regulations:

IEC 60534-2-1 EN 50274 ATEX Directive 2014/34/EU RoHS Directive 2011/65/EU

Warranty

The transmitter is warranted against defects in materials and workmanship for [Warranty Period] from the date of purchase. Contact the manufacturer for complete warranty details.
