Product catalog summary
Overview: The document provides comprehensive specifications and operational guidelines for the Brushless Delvo C Series electric screwdrivers by Nitto Kohki Co., Ltd. Key features include current-controlled torque systems, low-voltage brushless motors, and ESD protection, making them suitable for both hand-held and automatic machines.
Specifications: The screwdrivers are available in two models: DLV04C with a torque range of 0.05 - 0.4 Nm and DLV10C with a torque range of 0.2 - 1.0 Nm. They operate at speeds ranging from 100 to 1000 min-1 and include a built-in screw counting function to minimize human errors.
Features: These screwdrivers offer a current-controlled torque system for precise torque adjustments. They can be adapted for automatic machines with optional accessories such as flange couplings and vacuum pickups. The controller supports torque and speed settings across four channels and includes a built-in counting function.
Operational Modes: Two fastening modes are available: SOFT for high fastening loads and HARD for small fastening loads. The fastening process includes stages of start, during, and end of fastening, with current cut-off at the desired torque value.
Controller Specifications: The controller operates on AC100 - 240 V and supports external start-up control via input signals. It features a photocoupler input/output method and consumes 20 W on standby and 30 W during operation.
Cautions: Users should operate within a temperature range of +10 to +40 ℃ and avoid retightening screws to prevent exceeding the set torque. The power cord for the controller must be purchased separately.
Optional Accessories: Accessories include flange couplings, vacuum pickups for automatic machines, and torque measuring equipment like the DLT1173A Torque Checker.
Procedures: Key procedures include setting the operation channel to 'INPUT', enabling the count function, locking the controller button to prevent unauthorized changes, and connecting power sources as specified.
External Signals: Details are provided on input and output external signals via a signal terminal block, including service power source connections and signal specifications for various operations.
Torque and Speed Graphs: Graphs illustrate the relationship between output torque and rotation speed for the DLV04C and DLV10C models, serving as guidance without guaranteeing the output torque range.
Standards and Certifications: The document mentions ISO9001 and ISO14001 certifications, indicating compliance with international quality and environmental management standards.
