ABB PFEA113 Tension Electronic Equipment

(2) Remote monitoring

Through Profibus DP communication, the upper computer (such as PLC) can read tension values, sensor status, and alarm information in real time, and support remote sending of zero calibration, gain switching, and other instructions.

3. Key operational functions

(1) Zero point calibration

Trigger condition: When no tension is applied (such as when the coil is not running), execute it through the "Zero Set" menu on the panel or remote command.

Operation steps:

Enter the "ZeroSet" menu and select the corresponding sensor group (such as A, B).

After confirming that there is no tension, press "OK" and the display screen will show "ActionDone" to indicate completion.

(2) Gain scheduling

Application scenario: Suitable for changes in coil path (such as different wrrap angles), switching preset wrrap gain parameters through digital input or Profibus.

Setting method: Enable "GainScheduling" in the "SystemDefinition" menu, and configure the w_rap gain 1_ and w_rap gain 2h respectively.

Maintenance and upkeep

1. Preventive maintenance

(1) Regular check (recommended every 6 months)

Key operating points for inspection items

Check the torque of the fixing screws for sensors and connectors (e.g. 24Nm for M12 screws), and clean the dust or debris in the gap between the sensor and adapter board.

Confirm that the cable and shielding layer are not worn, and that the shielding layer is grounded at one end (distance ≤ 50mm) to avoid interference caused by grounding at both ends.

Ventilation openings for heat dissipation and environmental cleaning equipment ensure that the working environment temperature and humidity are within the rated range (without condensation or corrosive gases).

(2) Calibration and verification

Calibration cycle: It is recommended to perform accuracy calibration once a year, using standard weight or calibration equipment to verify measurement errors (should be ≤ ± 0.5% FS).

Verification method: Enter a known tension value through the simulation function in "DataMenu", and compare the displayed value with the theoretical value.
