Need help?Do you have a question about the ebm-papst A3G800-AU25-01 and is the answer not in the manual?
This document outlines the operating instructions for an ebm-papst device, providing comprehensive details on its function, usage, and maintenance.
The device is designed as a built-in component primarily for conveying air. It operates within power systems with grounded neutral (TN/TT power systems) and is intended for use in networks conforming to EN 50160 quality characteristics. The fan is equipped with integrated protective functions that automatically switch off the motor in case of faults such as rotor position detection errors, blocked rotor, line undervoltage, or phase failure. An automatic restart follows once the fault condition is resolved or the line voltage returns to permitted values. The device also features reverse polarity and locked-rotor protection for the motor. It includes an integrated PID controller, power limiter, and motor current limitation. Communication is supported via RS-485 MODBUS-RTU. The device incorporates a soft start function and EEPROM for parameter storage with a high number of write cycles.
The device is intended for stationary systems and requires all maintenance work to be performed as specified. It is designed to convey air at ambient air pressures between 800 mbar and 1050 mbar, within a permitted ambient temperature range. Operation must always be with all protective devices in place and in accordance with the operating instructions. The device should only be connected to circuits that can be switched off with an all-pole disconnection switch. When routing cables, it is crucial to ensure that cable glands are sealed and that there is no strain on the connections. For fans installed lying flat, the cable should be routed in a U-shaped loop to prevent moisture penetration into the terminal box. For fans installed upright, cable glands should be located at the bottom, and cables must always be routed downward. The device can be controlled via various inputs, including analog inputs for set values (0-10 VDC or 4-20 mA) and digital inputs for enabling electronics, resetting functions, or selecting parameter sets. It also provides fixed voltage outputs for external devices and an analog output for motor modulation level or speed. The device is designed to be EMC-compliant, but users may need to take additional shielding measures if impermissible radiation levels occur after installation.
Regular maintenance is crucial for ensuring a long service life and trouble-free operation. This includes checking the fans regularly for proper operation and soiling, with the frequency adapted to the degree of soiling. The preferred cleaning method is dry cleaning, for example, using compressed air. Aggressive cleaning agents, high-pressure cleaners, or pointed/sharp-edged objects should not be used. All cleaning agents must be completely removed. If severe corrosion is visible on load-bearing or rotating parts, the device must be switched off and replaced, as repair of such parts is not permitted. If cleaning does not eliminate vibrations, the fan may need rebalancing, and ebm-papst should be contacted for this service. The fan is equipped with maintenance-free ball bearings with a lifetime lubrication designed for 40,000 hours. If bearing replacement becomes necessary after this period, ebm-papst should be contacted. Maintenance intervals should be adapted to the actual level of dust exposure.
A safety inspection should be performed periodically, including checking the contact protection cover for intactness or damage, inspecting the device for damage to blades and housing, verifying the fastening of cables, checking insulation of cables for damage, and ensuring the tightness of cable glands. Condensation drainage holes should be checked for clogging, and welds for crack formation. Abnormal bearing noise should also be monitored.
For devices not operated for a lengthy period in a dry environment, it is recommended to start them up and operate at full speed for one hour at least every four months. In a damp environment, this should be done for at least three hours once a month to move the bearings and evaporate any condensate.
Disassembly of the product for disposal must be performed or supervised by qualified personnel. Components should be separated into categories such as steel and iron, aluminum, non-ferrous metal, plastics, insulating materials, cables and wires, and electronic scrap for recycling. Ferrite magnets can be disposed of with normal iron and steel. All country-specific legal requirements regarding disposal must be observed.
