Step 1: Zero CalibrationEnsure the roller has no web material. Set the digital multimeter to the ABB PFRA101 output terminals. Use the DIP switches on the ABB PFRA101 (ABB Pressductor System Controller) board to shift the base offset until the output signal aligns as close as possible to 0V or 4.00mA.

Step 2: Span CalibrationHang a known calibration weight over the roller following the exact web path. Calculate the expected force, then configure the gain DIP switches (S1/S2/S3 combinations) on the ABB PFRA101 board to scale the amplification factor until the output matches the calculated value.

Step 3: VerificationRemove the weight to ensure the ABB PFRA101 (Pressductor System Controller) output returns back to its zero baseline. Reapply the weight once more to confirm that the ABB PFRA101 (Pressductor System Controller) output repeats the same correct values before resuming production

Q1: What is the ABB PFRA101 control unit?

A: The PFRA101 ABB (ABB PFRA101) is a single-channel tension electronics amplifier developed by ABB based on its proprietary Pressductor technology. PFRA101 ABB is designed to condition and amplify the weak signals from magnetoelastic tension load cells and convert them into standard industrial analog outputs.

Q2: What is the rated input voltage for the PFRA101 ABB with ordering number 3BSE003911R115?

A: This specific version of the PFRA101 ABB has a fixed rated operating voltage of 115V AC (50/60 Hz). Field power supply must match this specification precisely to prevent internal circuit damage.

Q3: What are the physical design features of the field-housing version of PFRA101 ABB?

A: The field-housed PFRA101 ABB features a heavy-duty industrial enclosure for distributed on-site wall mounting. PFRA101 ABB comes equipped with 5 bottom-mounted cable glands that provide liquid-tight protection for the internal ABB PFRA101 circuitry against dust and moisture.

Q4: Is there an upgraded replacement model available if an existing PFRA101 ABB needs to be replaced?

A: Since the PFRA101 ABB is an obsolete legacy model, it is primarily available as a spare part. For system upgrades and modernization, ABB typically recommends replacing the PFRA101 with the new generation PFEA111 or PFEA112 tension electronics.
