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. Configurable digital filtering for suppressing mechanical vibration and noise interference.
4. Analog output 4‑20 mA / 0‑10 V for PLC / drive closed‑loop tension control.
5. Local LCD display for tension value reading, parameter setting and status diagnosis.
6. Channel self‑diagnosis: detect sensor break, overload and circuit fault, report alarm status.
7. LED status indication:
   • Green LED：Power supply normal, unit healthy
   • Yellow LED：Measuring signal active
   • Red LED：Over‑load / sensor fault / unit hardware fault

Installation & Wiring Requirements

1. Cut off power supply before wiring or replacement. Firmly fix PFEA111‑65 on machine mounting base. Hot‑swap is forbidden.
2. Install cable glands properly to guarantee IP65 protection grade; connect load‑cell sensor cable, power cable and analog output strictly per wiring drawing; separate sensor weak‑signal cables from high‑power cables to reduce electromagnetic interference.
3. Complete protective grounding according to ABB tension‑system specification.
4. After replacement, perform load‑cell calibration, set filter parameters and measuring range; verify analog output function before commissioning.
5. Replacement note: parameter download and recalibration are required after unit replacement. Cannot directly swap with DIN‑rail PFEA111‑20 because of mechanical housing difference.
