TPU-M1 MONITORING UNIT
The TPU-M1 monitoring unit monitors and manages the functions of combined fastening tools. Designed for use with eTensil brushless electric screwdrivers and nutrunner motors with mechanical clutch and automatic shut-off, it supplies the tools and provides programmable process control and data communication features for industrial assembly lines.

BASIC FUNCTIONS

• Automatic recognition of the connected tool and immediate configuration to its parameters to prevent setup errors
• Displays: OK/NOK result, tightening time and angle values
• Screw counting for Poka Yoke verification
• Detection of process anomalies (e.g., stripped threads, already tightened screws)
• Storage capacity for up to 99 tightening operations
• Interfaces with PLCs and other line devices; remote management possible
• Manages critical joints (e.g., flexible gaskets, rubber components)

PROGRAMMING — SMART PRO EVO
Configurable functions are available directly on the unit for fast, intuitive setup.

STARTING MODES

• Lever start
• Push-to-start
• Lever + push-to-start
• “Latched lever” + push-to-start (pistol models: push-to-start only; nutrunner motors: remote start available)

ADDITIONAL CONTROLS

• Starting block in case of anomalies
• Front illumination LED for work area lighting
• Untightening function: activable/deactivable with adjustable speed
• Soft start: adjustable acceleration ramp to ease screw engagement
• Tool speed: configurable within minimum/maximum range

PRE-SELF UNTIGHTENING / POST-SELF UNTIGHTENING / STOP-BY-TIME
Pre-self untightening: set untightening angle and pause between untightening and subsequent tightening (useful for connector operations). Post-self untightening: set untightening angle and pause before reverse rotation after tightening. Stop-by-time tightening: control cycle by set tightening time to fasten to a defined depth rather than a defined torque.

TIGHTENING STRATEGIES

• Torque control with mechanical clutch
• Torque control with mechanical clutch and tightening time monitoring
• Angle control with tightening time monitoring
• Time control (stop-by-time tightening)

FEATURES

• 8 programs to control the tightening process
• 1 programmable sequence up to 8 steps
• Retention: programmable waiting interval between programs
• I/O Port: 8 inputs / 8 outputs with 21 + 22 signal types
• 7 LEDs for immediate process status display
• Serial communication (RS232)
• Language selection: IT, EN, DE, FR, ES, TR
• ESD certification
• Power cable included
• Supply: 100–240 Vac (operational 230 Vac ±10% 50–60 Hz)
• Extended warranty: 2 years or 1 million cycles

APPLICATIONS
Industry 4.0 solution designed to interconnect with plant management systems for data exchange, remote visualization, control and management of tightening processes via cloud platforms.
