Atlas Copco Power Focus 3000 Controller Installation, Debugging, and Troubleshooting Guide

Use the+/- keys to set the target torque value.

Press ENTER to activate the Autoset function, and the corresponding LED indicator light will turn on.

Perform 5-8 actual tightening cycles (using real bolts/workpieces) until the LED goes out.

The LED turning off indicates that the system has found the optimal performance parameters and can be put into production.

4.2 Graph version programming steps

Press the PROG key and use the directional keys to select Pset → Quick Prog.

Enter the target torque value using the alphanumeric keyboard.

Press ENTER to activate Autoset (LED located at the bottom right corner of the front panel).

Tighten 5 to 8 times in the same way, and press the Result button to confirm after the LED turns off.

The system automatically stores the optimal parameters and prepares them for use.

Important note: During the Autoset process, it is necessary to use connectors (bolts, washers, workpieces) that are completely consistent with actual production, otherwise the obtained parameters can only be applicable to the current batch. If the workpiece batch or tool is changed, AutoSet must be re executed (the "Notice" at the beginning of the document emphasizes that any changes that affect the tightening result must be revalidated).

Common fault phenomena and systematic troubleshooting

Fault 1: Controller unable to power on

Check if the main fuse is blown (refer to the specifications in the table above).

Check if GFI trips - if it trips, first locate the leakage point.

Confirm whether the power supply voltage is within the range of 90-120VAC or 180-240VAC (automatic induction, but does not work if it exceeds the range).

Check the power cord wiring: brown/black=live wire, blue=neutral wire, green/yellow=protective ground, make sure it is correct.

Fault 2: Tool does not start or tighten without action

Confirm that the controller is in RUN mode (not programming or standby).

Check if the tool cable connector is fully locked (without shaking).

Check if the Pset parameter is written correctly (especially if the torque target value is 0).

Check the status of the indicator lights: green light=OK, yellow light=low torque warning, red light=high torque alarm. Frequent yellowing/reddening may be due to changes in joint characteristics and require a new Autoset.

If multiple axes are synchronized, check if the RBU functional level supports the required strategy.

Fault 3: Communication or data abnormality

Check the serial/Ethernet connection (there are Serial # 1, Serial # 2, Ethernet, Printer ports on the rear panel).

If using a third-party printer or data acquisition system, confirm that parameters such as baud rate and protocol match.

Attention should be paid to the sensitivity of internal electronic components to static electricity. Maintenance and repair must be carried out on an ESD certification workbench (example image provided in the document).

Fault 4: Overheating or abnormal power consumption

The power consumption of Power Focus itself is directly related to the tool load. The standby power consumption is about 20W. When idling, the S4/S7 tool consumes about 150W, and the S9 consumes about 200W. If the power consumption increases abnormally, it may be due to tool stalling or cable short circuit.

Check the ambient temperature. The controller specifies a maximum temperature of 40 ℃ and a relative humidity of ≤ 80% (below 31 ℃) or a linear decrease to 50% (40 ℃). If exceeded, forced heat dissipation is required.

Preventive maintenance and lifecycle management

6.1 Monthly Mandatory Inspection

Test GFI (press the test button).

Check the grounding continuity (the resistance from the tool housing to the main grounding terminal should be close to 0 Ω).

Check for wear, compression, or cuts on the outer sheath of the tool cable.

6.2 Software and firmware updates

The ServAid tool (available for download from DVD or official website) provides the latest security instructions, installation instructions, explosion views, and spare parts information, as well as the ability to check product discontinuation/update status.

6.3 Warranty and Motor Disassembly Prohibition

The document clearly states that the electric tool motor is a sealed unit, and unauthorized disassembly will void the warranty. The maintenance of the controller is also limited to authorized personnel. Any use of non original spare parts may also render the warranty invalid.

6.4 Scrapping and Environmental Protection Treatment

The product complies with the RoHS (2011/65/EU) and WEEE (2012/19/EU) directives, and the body and battery are marked with the "crossed trash can" symbol. When scrapped, it should be collected separately according to local regulations and should not be mixed with ordinary garbage.

Practical on-site checklist

Method for checking item frequency

GFI function: Press the rear test button once a month to confirm the trip

Ground continuity: Measure the resistance from the casing of the multimeter to the ground wire (<1 Ω) once a month

Visually inspect the appearance of the cable for any damage during each shift
