Introduction

The Hoerbiger electrohydraulic press actuator ePrAX control IS is designed for press brakes, offering precision control, smooth operation, and enhanced safety features. This manual provides details on installation, operation, and maintenance.

Safety

• Operators must follow all safety guidelines to prevent injury.
• Personal protective equipment (PPE) is mandatory during operation and maintenance.
• Hydraulic fluid must be handled carefully to avoid environmental hazards.
• Electrical hazards require proper grounding and isolation before working on the system.

System Description

• The ePrAX press actuator is an electrohydraulic drive unit for press brake cylinders.
• It includes a servo synchronous motor, hydraulic tank, valve block, and drive controller.
• Control is achieved through pressure regulation and valve sequencing.

Technical Data

• Operating pressure: up to 9 MPa.
• Temperature limits: Tank and valve block up to 70°C, servo motor up to 110°C.
• Electrical voltage: Requires proper grounding and control connections.
• Interfaces: Hydraulic fluid connections, electronic control, and safety monitoring.

Transport and Storage

• Use only designated lifting points for safe transportation.
• Store in a dry, vibration-free environment.
• Ensure all hydraulic fluid is drained before long-term storage.

Installation

• Follow the designated mounting points for actuator attachment.
• Connect hydraulic and electrical interfaces according to system specifications.
• Implement vibration damping if required.
• Ensure compliance with EN 12622 safety standards.

Initial Commissioning

• Fill the hydraulic tank with the recommended fluid.
• Perform system bleeding to remove air pockets.
• Test electrical connections before applying full power.
• Set counterholding pressure to secure beam positioning.

Operation

• Monitor operating statuses such as idle, preclosing, working speed, and decompression.
• Control beam movements via programmed sequences.
• Monitor hydraulic fluid levels and pressure sensors for optimal performance.

Maintenance

• Follow scheduled inspections for hydraulic and electrical components.
• Replace hydraulic fluid, filters, and worn seals periodically.
• Check for leaks and secure fittings regularly.

Troubleshooting & Fault Elimination

• Analyze alarm conditions and LED displays for diagnostics.
• Check hydraulic pressure and fluid contamination levels.
• Replace defective drive controllers, pressure sensors, or motor components as needed.
