Application Cases of ABB PFSK115 (YM322001-EX) across Different Industries

Carbon steel cold rolling industry

Adopted in tandem cold mills and single-stand cold reduction lines for carbon steel strips. It processes distributed force signals across the entire strip width and delivers flatness data to the roll stand controller for bending, tilting and cooling regulation. This helps minimize strip breakage and downgraded coils, lifting the yield of automotive steel, tin plate and electrical steel.

Stainless steel rolling industry

Implemented in stainless steel cluster mills and bright annealing lines. Reliable signal processing ensures precise flatness control for ultra-thin stainless steel foil. With strong immunity to on-site thermal interference and rolling vibration, it effectively prevents edge wave and center buckle defects for decorative stainless steel and battery-grade stainless substrates.

Aluminium & aluminium alloy rolling industry

Applied in aluminium hot rolling mills, cold rolling mills and foil mills that produce packaging foil, automotive aluminium sheets and lithographic aluminium base. This board processes weak force signals from low-load measuring rolls, supports high-speed rolling at up to thousands of meters per minute, and maintains uniform flatness of thin aluminium foil without surface indentation.

Copper and non-ferrous metal processing industry

Deployed on copper strip and brass rolling lines for electronic copper foil, connector copper strips and heat exchanger fin materials. Precise flatness measurement stabilizes downstream slitting and electroplating processes, and reduces edge wave and camber defects for high-precision electronic copper strips.

Metal service center & strip processing line

Used for recoiling, tension leveling and inspection lines. The module supplies continuous flatness monitoring data for quality classification and product sorting. It archives flatness records to support product traceability and quality certification for end customers.

Special alloy & high-value metal rolling

Well suited for titanium alloy, nickel alloy and high-temperature alloy rolling lines catering to aerospace and energy sectors. Its high signal resolution detects subtle flatness deviations of difficult-to-form alloy strips and meets stringent flatness tolerance standards for aerospace metal materials.

Pre-operation check

Fully cut off the rack power supply before installation or removal;

Inspect the module for burn marks, corrosion and bent backplane pins;

Confirm the assigned slot matches the system configuration;

Ensure the backplane bus connector is clean and securely connected;

Check ambient temperature and ventilation, and keep the module away from vibration, oil mist and intense electromagnetic interference.

Module installation

Slide the board gently along the slot guide rails;

Push the module steadily until the rear connector is fully mated with the backplane;

Tighten the front panel mounting screws to secure reliable grounding;

Avoid applying excessive force to prevent damage to the backplane gold fingers.

Power-on and startup procedure

Verify all modules are properly installed and wiring is completed;

Energize the rack power supply step by step;

Monitor front panel LED indicators: steady green power LED indicates normal power supply; extinguished red fault LED means no initial hardware fault;

Wait for the system to finish backplane bus initialization and synchronize with the main controller;

Log into the Stressometer software to confirm the module is recognized correctly.

Normal operation

Once started, the module automatically acquires flatness sensor signals in real time;

It carries out signal conditioning, offset compensation and data preprocessing;

Transmits valid measurement data to the main control unit through the internal backplane bus;

Receives parameter commands from the main controller and updates calibration coefficients;

Runs continuously without manual intervention under normal operating conditions.

Parameter configuration and calibration

Access the authorized configuration interface via Stressometer software;

Read existing calibration data before making changes;

Complete channel zero calibration and gain calibration based on field sensor conditions;

Store calibrated parameters into the module’s non-volatile memory after adjustment;

Download the configuration and trigger a soft restart to activate new parameters;

Back up all calibration files promptly once calibration is finished.

LED indicator explanation

Green LED: Power status, steady on = normal power supply; off = no input power;

Red LED: Fault alarm, steady on = hardware failure; flashing = communication error or channel signal out of range;

Yellow LED: Channel activity indicator, flashes periodically during signal sampling.

Fault handling

Power LED off: Check rack power supply, backplane fuse and slot contact condition;

Red fault LED illuminated: Retrieve diagnostic codes from host software; isolate the faulty module by swapping slots;

Communication failure: Check backplane bus connection, module address and firmware version consistency;

Abnormal signal readings: Re-calibrate the channel, inspect sensor cables and sensor health;

Power down the module for 30 seconds to clear temporary software anomalies;

Discontinue operation and replace the module if internal hardware damage is verified.

Shutdown and removal

Back up all calibration and configuration data in advance;

Switch off the rack power and wait no less than 5 minutes for capacitor discharge;

Loosen front panel screws and pull the module out evenly;

Place the removed module into anti-static packaging;

Avoid direct contact with circuit components and gold fingers.
