Need help?

Do you have a question about the ebm-papst VBS0500CTTLS and is the answer not in the manual?

This document describes the ebm-papst VBS0500CTTLS fan, a built-in device designed for conveying air according to its technical data.

Function Description

The VBS0500CTTLS is a 3-phase fan with a nominal voltage range of 380-480 VAC and a frequency of 50/60 Hz. It operates with a clockwise rotation when viewed toward the rotor. The device is equipped with an E15031-55 motor, offering a preliminary speed of 2480 rpm and a power consumption of 4150 W. It features an IP55 degree of protection and "F" insulation class.

The fan includes several technical features for enhanced control and monitoring:

Operation and alarm display with LED: Provides visual feedback on the device status.
External 15-50 VDC input: Allows for parameterization.
Alarm relay: For signaling operational issues.
Integrated PI controller: Enables precise control.
Configurable inputs/outputs (I/O): Offers flexibility for integration into various systems.
MODBUS V6.3 and RS-485 MODBUS-RTU: For communication and control.
Motor current limitation: Protects the motor from excessive current.
Soft start: Ensures a gradual and controlled startup.
Voltage output 3.3-24 VDC (Pmax = 800 mW): Provides power for external devices.
Control interface with SELV potential: Safely disconnected from the mains.
Thermal overload protection: Safeguards electronics and the motor.
Line undervoltage / phase failure detection: Monitors power supply quality.
Vibration sensor: Detects excessive vibrations.

The device is intended for use in power systems with grounded neutral (TN/TT), phase conductor grounding, or IT power systems, and must adhere to EN 50160 network quality characteristics. It is designed for stationary systems, conveying air at ambient air pressures between 800 and 1050 mbar, and within specified ambient temperature ranges.

Usage Features

The VBS0500CTTLS is designed for safe and reliable operation, but users must adhere to specific guidelines:

Safety Precautions:
- Always disconnect power and ensure it cannot be switched back on before working on the device.
- Wait five minutes after disconnecting voltage before opening the device.
- When working on an electrically charged device, stand on a rubber mat.
- Secure rotating parts against accidental contact and wait for them to stop before maintenance.
- Ensure all protective devices are in place and functioning.
- Protect long hair and avoid loose clothing or jewelry near rotating parts.
- Wear appropriate hearing protection if the sound pressure level exceeds 70 dB(A).
- Ensure sufficient protection against accidental contact with hot surfaces.
- Transport the fan carefully in its original packaging to prevent bearing damage or impeller deformation.
- Only connect the fan to circuits that can be switched off with an all-pole disconnection switch.
- Route control lines separately from supply lines with a clearance of >10 cm to prevent malfunctions.
- Ensure cable ends are connected in a dry environment to prevent water ingress.
- Use AC/DC-sensitive residual current devices (type B or B+) if an RCD is required, with a trip threshold of 300 mA and delayed tripping.
Installation:
- Verify nameplate information matches connection data and power supply voltage.
- Use cables designed for the current level indicated on the nameplate, with a minimum cross-section of AWG 26/0.13 mm² and rated for 105 °C.
- Ensure proper protective earth connection according to EN 61800-5-1.
- Strip cables only as far as necessary, ensuring cable glands are sealed and connections are strain-relieved.
- Tighten screws and cable glands to specified torques (refer to product drawing).
- Route cables in the terminal box to allow the cover to close without resistance.
- Ensure the terminal box is completely closed and sealed.
Operation:
- Only operate the device after proper installation, with all safety mechanisms and electrical hookups in place.
- Ensure no combustible or flammable materials are near the fan.
- Check for visible external damage and functional protective devices before switching on.
- Verify air flow paths are clear of foreign matter.
- Apply nominal supply voltage and start the device by changing the input signal.
- Avoid operating the device in an unbalanced state (e.g., due to dirt or ice formation), with severe vibration, or in resonant operation.
- Do not convey solids, abrasive particles, or highly corrosive air (unless specifically designed for it).
- Do not operate in explosive atmospheres or as a safety component.
- Do not switch the motor on and off via the power supply in cyclic operation.
Integrated Protective Features: The device automatically switches off in case of:
- Rotor position detection error (restarts automatically).
- Blocked rotor (restarts automatically after blockage is removed).
- Line undervoltage (restarts automatically when voltage returns to permitted values).
- Phase failure (restarts automatically after 10-40 seconds when all phases are correctly supplied).

Maintenance Features

Regular maintenance is crucial for ensuring the longevity and reliable operation of the VBS0500CTTLS fan.

General Maintenance:
- Store the device in a dry, vibration-free environment, protected from weather and dirt, in its original packaging.
- ebm-papst recommends storing the device for no longer than one year.
- Ensure all cable glands are fitted with dummy plugs during storage.
- Perform all maintenance work while the device is in a stationary system.
- Periodically check the device's electrical equipment for loose connections and defective cables.
- Clean the device regularly to prevent dirt deposits that could lead to imbalance or vibration.
- Do not use high-pressure cleaners, acidic, alkaline, or solvent-based cleaning agents.
- Do not use pointed or sharp-edged objects for cleaning.
Inspection Intervals (every 6 months):
- Contact protection cover: Visual inspection for damage or missing parts. Replace if necessary.
- Device for damage to blades and housing: Visual inspection. Replace if necessary.
- Fastening the cables: Visual inspection for proper fit. Fasten if loose.
- Cables for damage or wear/deposits/insulation and damage: Visual inspection. Replace cables if damaged.
- Tightness of cable gland: Visual inspection. Retighten if loose or damaged.
- Condensation drainage holes: Visual inspection. Open holes if clogged.
- Internal/external bearing noise: Acoustic check. Clean impeller or replace device if necessary.
- Vibration test: Start-up or deceleration measurement. Clean impeller or replace device if necessary.
Troubleshooting: The manual provides a detailed troubleshooting guide for various malfunctions, including:
- Impeller running smoothly: Possible causes include imbalance in rotating parts. Remedy: Clean the device, replace if imbalance persists, check for missing weights.
- Motor not turning: Possible causes include mechanical blockage or line voltage fault. Remedy: Remove blockage, restore power supply, check connections.
- Audible grinding or scraping noise: Possible causes include impeller grinds on inlet ring or mechanical blockage. Remedy: Align inlet ring, remove blockage.
- Other faults: The manual lists various fault messages (e.g., phase failure, output stage overheating, communication error, hall sensor error, motor blocked, speed limit exceeded, rotor position sensor calibration error, DC-link undervoltage) with possible causes and remedies.
Suppression of Speed Ranges: The integrated vibration sensor can measure vibration velocities. Speed ranges with excessively high vibration levels can be blocked out using EC-Control software, preventing continuous operation in these ranges.
Disassembly and Disposal:
- Disassembly should be performed by qualified personnel.
- The product contains valuable materials (steel, copper, aluminum, plastic) that are generally considered for recycling.
- Electronic scrap, e.g., circuit boards, should be disposed of separately.
- Ferrite magnets can be disposed of as normal waste.
- Contact ebm-papst for specific disposal information.
