Accupulse 4+ Advantages

Unique Technologies for Mechanical Pulse Torque Sensing
AccuPulse 4+ pulse torque sensing uses a patented drive and non-contact transducer
to deliver accurate, durable torque measurement during pulsing.

1. High Sensitivity
Torque Transducer
The transducer can reliably measure torque during pulsing with a non-contact design resulting in high durability of the sensor block.
2. Patented Drive Mechanism
Unique drive mechanism optimizes the pulse behavior for torque sensing.
3. Snug Detection
The tool measures the angle between pulses to help determine snug. To help with repeatability and difficult applications.
4. Buffering
AccuPulse 4+ keeps working even when out of wireless range - ensuring the tool completes the entire batch without interruption. Seamless reconnection when back in wireless range.
5. Four Microprocessors
At the heart of the AccuPulse 4+ are four specialized microprocessors—each dedicated to motor control, communication, torque control, and transducer.

Traceability:

Advanced Traceability Data Management
AccuPulse 4+ series delivers powerful benefits through its advanced data capture and wireless communication capabilities, enabling seamless integration with modern assembly systems. By recording and transmitting key metrics such as torque value, angle, fastening curve, OK/NOK status, pulse count, and fastening time. The tool ensures complete visibility into each fastening operation.
This level of traceability allows for real-time quality control, immediate feedback on fastening results, and data-driven process optimization. The wireless communication feature enables the tool to not only send data but also receive updated parameters or instructions from a MES, enhancing flexibility and responsiveness on the production line.

Wireless Communication
• Torque value
• Angle value
• Fastening curve
• OK/NOK status
• Pulses
• Fastening time

Affordability:

AccuPulse 4+ delivers smart savings with lower cost maintenance, powerful battery efficiency, and rugged durability—giving you high end results without the high-end cost.
The AccuPulse 4+ offers long-term value through oil-free mechanical pulse technology—
eliminating routine oil changes and reducing maintenance costs. Its advanced lithium-ion battery provides extended runtime, and fewer replacements, keeping production lines moving efficiently. Internally, the tool is built to withstand the rigors of industrial use. Vibration damping, protective internal coatings, and rubber isolation mounts work together to shield sensitive electronics from shock, moisture, and wear. A non-contact torque transducer further reduces mechanical failure and ensuring consistent accuracy over time.

User-Friendly:

Designed for ease of use with intuitive controls, visual feedback, hanging option, and simple connectivity for seamless operation in any assembly environment.
Developed with user-friendliness at its core, this tool offers a suite of features designed to simplify operation and boost productivity on the assembly line. The improved setup process allows for streamlined configuration and torque output adjustment, with the flexibility of both automatic and manual setup. From variable or fixed trigger control to a bright LED light. Visual indicators, such as the multi-view tightening confirmation lamp, provide immediate feedback, while the USB Type-C connection enables fast setup and seamless data transfer.
Tool Manager Data
Tool Manager provides the operator the ability to view history rundown data, like the fastening curve and pulses.

Improved Setup Process - Reduced Setup Time
There are two methods available for programming the tool on the application: Auto Torque Offset and Manual Torque Offset. The Manual Torque Offset method provides enhanced control, allowing for more precise customization during tool programming.

Accuracy:

Less Mean-Shift

Torque Sensing Plus - Tool will shut off when the both sensor torque and angle between pulses meet the shut off condition; Target torque is met, and target angle is met or less 
• Less torque increase
• Better repeatability over inconsistent conditions. Improved mean shift by 34%
  -Works for prevailing torque, pulling parts together, softer joints or bolt pattern misalignment

Support Features:

Snug Detection
AccuPulse 4+ introduces advanced Torque Sensing with Pulse Angle Monitoring, elevating
fastening reliability by tracking angle changes between pulses to ensure precision. Users
can select from snug detection 1 through 7, it adjusts the threshold angle to match specific
application requirements, allowing for greater control and repeatability.
Buffering
AccuPulse 4+ continues to operate outside wireless coverage, ensuring uninterrupted batch
completion through autonomous control protocols. (Can store up to 50 rundowns) *Does not
work with graphing enabled & only applies to radio tools
Cross Thread Reduction
Two types of the programmable features to reduce cross thread.
Soft Start: Sets the no load speed to the lowest rpm for a programmable time after trigger is pulled (time setting: 0.1-1.0 sec).
360° Reverse: 360° reverse rotation for thread alignment then rotate forward.
Disable Reverse
The tool is prevented from operating in reverse rotation when this function is ON.
Retightening Prevention Function
This function prevents the tool from operating within a selected time period after it automatically stops from the torque control function. The switch will not operate even if engaged during this time period (time setting: 0.1-3.0 sec).
Variable Speed Control Function
Speed can be controlled by use of the trigger. Speed control function ON and OFF can be selected by remote.
Snug Torque Detection Delay
The tool doesn’t activate Snug Torque Detection mode and ignores loads in the middle of rundown for a selected time period (time setting: 0.1-3.0 sec).
Angle Error Shut-Off
Tool reports NOK and EA when the rundown exceeds its upper angle limit to prevent the material from being damaged.
Rundown Error Detecting Function
If the tool is activated before the programmable minimum runtime, the tool alerts the operator to a NOK fastening (time setting: 0.1-3.0 sec, 0.1 sec per stage).

Ignore Rundown Result before Snug
When this function is ON and tool stops before snug point due to trigger release, the rundown result isn’t recorded.
Maintenance Interval Alarm (Pulse Time)
This alarm counts the pulsing time that has been accumulated since the tool started to be used and reminds you of maintenance timing. When you have 1 hour or less to go before the set time, the control panel display will give you a warning (setting value 0 hours to 99 hours).
Socket Extension Length
Three different socket extension length to choose from. (40mm 1.5 inch, 150mm 6 inch, 250mm 10 inch). You are able to change it during the Torque Offset Procedure.
