CONTROL UNIT TPU-C3 — ADVANCED MODEL

TPU-C3 — advanced model — control unit represents a great innovation INDUSTRY 4.0 able to manage all tools functionalities. It works with eTensil electric brushless screwdrivers and nutrunner motors with torque/angle current control, where the torque is detected by measuring the current used by the motor of the connected tool while the angle is detected by specific Hall sensors always integrated in the tool.

• Allows in-process torque adjustments during work by modifying the relevant parameter on the operating panel
• Displays at the end of each cycle: OK/NOK status, the ANGLE VALUE together with TIGHTENING TIME tightening time and TORQUE VALUES
• It detects process anomalies, by CHECK TIGHTENING TIME for example stripped threads or screws already tightened
• It communicates with the outside, the PLC or other devices, and can be controlled remotely
• Works as Poka Yoke system when tightening critical joints. Should you have elastic gaskets, rubber elements or other materials, the control unit verifies that these are present or not during the process
• It interfaces with external equipment, the PLC, or other devices on the production line, such as workpiece‑clamping jigs, accessory selectors, and screw‑vacuum systems for automatic pick‑and‑place operations
• It can be managed remotely
• Allow to communicate the phase and the system status and to remote control the tool

FUNCTIONS: here are some of them, essentials to monitoring a tightening process correctly and making it reliable.

• 8 programs to control tightening process
• 1 programmable sequence up to a max of 8 steps
• Retention: programmable waiting interval between programs
• Automatic recognition of the connected tool and setting
• Screws counting: effective Poka Yoke device
• Min/Max tightening time control – Poka Yoke System
• Min/Max tightening angle control – Poka Yoke system
• Settable untightening speed
• 2 level password: to protect the set parameters or totally block the system
• Unit calibration
• Available measurements units: Nm/Lb/In./Kgf.cm
• Serial communication (RS232)
• Language selection (IT, EN, DE, FR, ES,TR)
• Storing the outcome of the last 99 tightening
• Interfacing with working stations and its devices
• Selection of programs from I/O (remotely)
• Program Source function: when external devices – such as automatic accessory selectors – are connected, it is possible to manage the program‑selection mode

• “SMART THREAD” function for processing of selfthreading, self-tapping, self-drilling screws, or else where the final torque value is lower than thread forming torque
• “SMART SPEED” function useful for speeding up the production process. It is possible to create a “two-phase” tightening strategy: screwdrivers start with a high-speed rotation until reaching the set angle, then rotate at a pre-defined speed that allows to maintain the accuracy of the result
• “S.R.O. Smart Range Optimizer”function: automatically identifies the most suitable final speed range to ensure the best tightening performance based on the set torque. The unit analyzes the selected torque value and dynamically calculates the optimal speed, which varies depending on the connected screwdriver model. The operator can then select, within this range, the speed that best fits the application.
  This prevents over‑torque errors, improves tightening quality, and increases the reliability of the entire tightening cycle.

PROGRAMMING SMART PRO EVO, other functions can be set on the unit:

TIGHTENING STRATEGIES

• Torque control
• Torque control and tightening time monitoring
• Torque control with tightening angle monitoring
• Torque control with time and tightening angle monitoring
• Angle control and torque and time monitoring
• Time control and torque and angle monitoring (Stop-by-time tightening)

• PRE-SELF UNTIGHTENING: it is possible to set the untightening angle and the pause between the untightening and the subsequent tightening. This strategy finds its application in the electrical / electronic field, for example when it is necessary to open and then close connectors to insert electrical wires (see video 1)
• POST-SELF UNTIGHTENING: the untightening angle is settable as well as the time pause of left rotation start after the tightening end (see video 2)
• STOP-BY-TIME TIGHTENING: to tighten in depth and not to defined torque, by controlling the cycle with set tightening time. When it is necessary to tighten threaded fasteners to a certain height and not to a defined torque. This is made by checking the tightening time (see video 3)

FEATURES

• I/O Port : 8 inputs/8 outputs programmable (21+22 signal types)
• 7 LEDs for immediate display of the process status
• ESD certification
• Power cable
• 230 Vac ±10% 50-60 Hz
• EXTENDED WARRANTY: 2 years or 1 million cycles

APPLICATIONS

INDUSTRY 4.0 solution: designed to interconnect with the production plant management systems or for data exchange and to allow remote visualization, control and management of tightening processes through CLOUD platforms.
