Control units. Smart power
Control units designed and built by Fiam for the range of solutions based on current control are truly innovative, and constitute the “smart core” that programs, monitors and controls all functions of the tools associated with it.
These sophisticated instruments work in perfect synergy with with electric screwdrivers and nutrunner motors. They not only provide tools with the correct power supply, but also feature a large number of programmable functions compared to others on the market, and are faster, simpler and more intuitive to use.
TPU-C1 and TPU-C3 basic functions
Essential functions to correctly and quickly manage a tightening process and make it reliable.
- Automatically and immediately recognizing the connected tool and setting the applicable parameters range for it.
- Allow in-process torque adjustments by modifying the relevant parameter on the operating panel.
- Screw counting this function turns the system into an effective Poka Yoke device. The tightening results are visualized on the unit display, highlighted by the leds.
- Storing the outcome of the last 99 tightening.
- Check tightening time to detect process anomalies like overtreading and already tightened screws.
- Communication with master PLC and others devices: 8 + 8 signals I/O freely programmable that offer several functionalities to be chosen from 9 + 11 signals (TPU-C1) and 21 + 22 signals (TPU-C3). Allow to communicate the phase and the system status and to remote control the tool.
- Displaying of tightening results
- TPU-C1 model: OK/ NOK status, torque value in Nm or other unit of measurement, tightening time value
- TPU-C3 model: OK/ NOK status, torque value in Nm in Nm or other unit of measurement, tightening time value, angle value.
- Interfacing with working stations. In presence of Jigs, workpieces locking devices can be activated/ deactivated.
- “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.
- Tightening strategies
- Torque control
- Torque control with tightening time monitoring
- Additional tightening strategies of TPU-C3
- Torque control with tightening angle monitoring
- Torque control with time and tightening angle monitoring
- Angle control and torque monitoring
- Time control and torque monitoring (Stop-by-time tightening).
Programming “SMART PRO EVO”
eTensil is the unique screwdriver that allows changing the starting mode without modifying the mechanical configuration.
FOUR START UP MODES can be set on the control unit:
- lever start
- push to start
- lever + push to start
- “Latched lever” + push to start.
Other functions can be activated / deactivated acting directly on the control unit:
- CONFIRMATION REQUESTED FOR ANOMALY (by pressing ESC button)
- CONFIRMATION REQUESTED FOR END OF CYCLE (by press ENTER button)
- UNTIGHTENING
- CLOCKWISE or counterclockwise tightening.
The main feature of these advanced units is the possibility to set different control functions:
- SOFT START. The ramp speed acceleration is not fixed but it is possible to set the time acceleration to ease screw engagement
- TOOL SPEED can be set within the minimum / maximum range
- MANAGEMENT OF ALLOWED ERRORS
- FRONT LED LIGHTING adjustable with intensity from 0 to 100%.
The additional functions in the TPU-C3 advanced model
In addition to all the features of the basic model, which guarantee continuous control over the tool status, tightening process and work cycle, the TPU-C3 advanced control unit also has extra programming and customisation functions
PROGRAMMING
Possibility to set up to 8 tightening programs with torque, angle and time control/monitoring. The programs can be managed in sequence and can also be selected remotely in single mode or with binary combination, which allow to set both the number of screws and the torque values.
DISPLAYING OF ALL TIGHTENING PARAMETHERS
The advanced TPU-C3 model displays the angle value at the end of each cycle together with tightening time and torque values. To always keep the assembly process under control.
MONITORING OF THE TIGHTENING ANGLE
It can work 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.
This is made by measuring the angle and comparing it with a range set by
the operator during the programming phase.
SMART PRO EVO
Other additional settable features are:
- PRE-AUTO 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.
- POST-AUTO UNTIGHTENING: it is possible to set the untightening angle as the pause time between untightening and subsequent tightening
- STOP-BY-TIME TIGHTENING
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.
TIGHTENING STRATEGIES
- Torque control
- Torque control with tightening time monitoring
- Torque control with tightening angle monitoring
- Torque control with time and tightening angle monitoring
- Angle control and torque monitoring
- Time control and torque monitoring (Stop-by-time tightening)
