FAQ;
1. Installation & Commissioning
1.1 What are the critical installation guidelines?
Proper installation is essential for reliable operation. Adhere to Rexroth’s installation instructions and the following key points:
Mounting Location: Install in a well-ventilated area with easy access for maintenance. Avoid direct sunlight, high-temperature surfaces (e.g., exhaust manifolds), and areas prone to vibration or contamination.
Pipeline Preparation: Flush all hydraulic lines before connection to remove debris, rust, or machining residues. Use proper tube bending techniques to avoid kinks that restrict flow.
Port Identification: Strictly follow port markings (P = supply, T = return, A/B = working ports) to prevent reverse flow, which can damage internal components.
Torque Specifications: Use a calibrated torque wrench to tighten flange bolts and tube fittings to the values specified in the manual (typically 25-35 N·m for flange bolts). Over-tightening may warp the valve body; under-tightening causes oil leaks.
Electrical Connection: Ensure the power supply matches the 24V DC rating. Use shielded cables for control signals to minimize electromagnetic interference (EMI). Ground the valve body and control cabinet per local electrical codes.
1.2 How to perform initial commissioning?
Commissioning should be conducted by qualified personnel after the hydraulic system is filled, bled, and pre-pressurized. Follow this step-by-step process:
Pre-Commissioning Check: Verify all mechanical and electrical connections are secure. Confirm the hydraulic oil level is within the recommended range and the oil is at operating temperature (20-40°C).
Power-On Verification: Apply power to the valve’s electronic amplifier. Check that the status LED (if equipped) illuminates steadily (no flashing, which indicates a fault).
Zero Adjustment: Apply a 0% control signal (0 mA). The connected actuator should remain stationary. If drift occurs, adjust the zero potentiometer (located on the amplifier) until movement stops.
Flow Characterization: Gradually increase the control signal from 0% to 100% (0-800 mA) and observe the actuator’s speed. It should increase smoothly and linearly. Note any irregularities (e.g., jerking, sudden speed changes) for further troubleshooting.
Load Testing: Apply rated load to the actuator and repeat the flow characterization. Confirm that speed consistency is maintained (pressure compensation function test).
Emergency Stop Test: Activate the system’s emergency stop to ensure the valve returns to the neutral position immediately, stopping the actuator.
