System Overview

Composition: Composed of PFEA111/112 tension electronic devices and various types of weighing sensors such as PFCL 301E and PFTL 301E, used for web tension measurement systems.

Function: To achieve precise measurement, monitoring, and control of web tension, PFEA112 also supports Profibus DP fieldbus communication.

Technical foundation: Based on Presductor ®  Technology perceives mechanical forces through electromagnetic field changes and generates signals without the need for physical displacement.

Core functions and features

Measurement and output: Can receive input from 2 weighing sensors, provide voltage and current output A+B, and have adjustable filtering. The display screen can show content such as A, B, A+B, A-B, etc.

Installation flexibility: There are two versions available: IP 20 (non sealed, DIN rail installation) and IP 65 (NEMA 4, wall mounted), to adapt to different environments.

Configuration and Calibration: Supports quick and complete settings, can be set by hanging heavy objects or calculating package gain, and can perform zero point settings and other operations.

Compatibility and Compliance: Compliant with multiple international standards and certifications, such as CE marking, electrical safety certification, hazardous area certification, etc., and also meets RoHS and WEEE directives.

Installation and debugging

Installation requirements: The installation of weighing sensors and electronic units must follow specific specifications, including cleaning the surface, correctly connecting cables, ensuring the flatness of the installation plane, and also considering factors such as dynamically balanced measuring rollers and self-aligning bearings.

Wiring and Connection: Specific specifications of cables are recommended, and attention should be paid to the connection of cable shielding layers, distance from interference sources, etc. Multiple IP 20 version devices need to be connected synchronously.

Debugging steps: including basic settings (language, units, etc.), quick or complete settings (package gain, output parameters, etc.), checking sensor signal polarity and functionality, etc.

Technical Parameter

Power supply: IP 20 version is 24 V DC (18-36 V DC); The IP 65 version can be connected to 24 V DC (18-36 V DC) or 85-264 V AC.

Measurement range: The zero point setting range is ± 2.0 × Fnom, and the dynamic measurement range (including zero point setting) is -2.5 × Fnom to+3.5 × Fnom (Fnom is the nominal load of the weighing sensor).

Output: Voltage output 0-10 V (range -5 to+11 V), current output 4-20 mA (range 0 to 21 mA), with multiple filtering settings available.

Environmental parameters: operating temperature from 0 to+55 ° C (certification range+5 to+55 ° C), storage temperature from -40 to+70 ° C, relative humidity from 5 to 95% (non condensing), etc.

Operation and maintenance

Operation: Includes startup and shutdown processes, with continuous measurement during normal operation. Measurement values and menus can be viewed through the operation panel.

Maintenance: Regularly inspect the weighing sensor, electronic unit, and connecting cables, such as cleaning gaps, tightening screws, and checking for cable damage.

Troubleshooting: Provides common fault symptoms and solutions, such as signal noise, unstable zero point, no signal output, as well as methods for handling errors and warning messages.
