The BE350 voltage regulator maintains the same sensing inputs, excitation outputs, and control characteristics, ensuring your generator operates exactly as it did with the original Marathon AVR.

Installation Overview - BE350 AVR Replacement

Installing the Basler BE350 as a replacement for the Marathon SE350 is straightforward due to the identical mechanical and electrical design. However, all voltage regulator installations should be performed by qualified electrical technicians familiar with generator systems. General installation steps include:

Step 1: Safety Precautions - Disconnect all power sources to the generator. Ensure the generator is completely shut down, and allow sufficient time for capacitors and electrical components to discharge. Lock out and tag out the generator control panel to prevent accidental starting during installation.

Step 2: Remove Existing AVR - Document the existing wiring connections with photographs or detailed notes. Carefully disconnect all wiring terminals from the existing SE350 voltage regulator, noting wire colors and terminal positions. Remove mounting fasteners and extract the old AVR from the generator control panel.

Step 3: Install BE350 - Position the new Basler BE350 in the same mounting location as the removed SE350. The mounting holes align perfectly with existing mounting points. Secure the BE350 using appropriate fasteners, ensuring the unit is firmly mounted to prevent vibration-related issues.

Step 4: Electrical Connections - Connect all wiring terminals to the BE350 exactly as they were connected to the SE350. The terminal layout is identical, making this a one-to-one replacement. Verify all connections are tight and properly seated. Ensure no wire strands are exposed that could cause short circuits.

Step 5: Voltage Adjustment and Testing - Before applying power, visually inspect all connections. Start the generator and allow it to reach normal operating speed. Using a calibrated multimeter, measure the output voltage. Adjust the voltage trim potentiometer on the BE350 to achieve the desired output voltage (typically 120V, 240V, or 480V depending on your system). Test the generator under load to verify proper voltage regulation across the load range.

Step 6: Final Verification - Monitor generator operation for several minutes, checking for stable voltage output and proper AVR operation. Verify voltage regulation under varying loads if possible. Document the installation date and initial settings for maintenance records.
