Main Functions

1. Supply excitation and acquire measuring signal from dual tension load‑cells.
2. Calculate tension value of individual channel, sum(A+B) and difference(A‑B).
3. Built‑in PID closed‑loop tension control with auto‑tune function, output control signal to drive / brake unit.
4. Configurable digital filtering for suppressing mechanical vibration and site electromagnetic noise.
5. Analog input‑output for local signal interconnection with PLC and drive system.
6. Local LCD display for tension reading, PID parameter setting and unit status diagnosis.
7. Profibus‑DP communication for remote reading tension value, alarm status and parameter download.
8. Channel‑level self‑diagnosis: detect sensor break, overload, cable fault, report alarm status.
9. LED status indication:
   • Green LED：Power supply normal, unit healthy
   • Yellow LED：Measuring signal / Profibus‑DP communication active
   • Red LED：Over‑load / sensor fault / control‑loop fault / unit hardware fault

Installation & Wiring Requirements

1. Cut off power supply before wiring or replacement. Mount PFEA112‑20 firmly on DIN‑rail inside cabinet. Hot‑swap is forbidden.
2. Connect load‑cell sensor cable, power cable, analog signal and Profibus‑DP bus cable strictly per wiring drawing; separate weak‑signal sensor cables from high‑power cables to reduce electromagnetic interference.
3. Complete protective grounding according to ABB Pressductor tension‑system specification.
4. After replacement, perform load‑cell calibration, set PID parameters, complete Profibus‑DP station address configuration; verify measuring, closed‑loop control and bus communication function before commissioning.
5. Replacement note: sensor calibration and PID parameter download are mandatory after unit replacement. This part is updated replacement for 3BSE030369R0020, hardware pin‑to‑pin compatible, but parameters must be re‑downloaded。
