Installation Overview

Installing the BASLER AVC63-12B2 Automatic Voltage Regulator requires basic electrical knowledge and adherence to proper safety procedures. Before beginning any installation work, always disconnect all power sources and discharge any stored energy in the generator system. Here's a general overview of the installation process:

• Step 1: Remove Old AVR and Document Connections – Carefully disconnect the existing voltage regulator, taking detailed notes or photographs of all wire connections, terminal positions, and wire colors. Label each wire according to its terminal designation (sensing input, excitation output, auxiliary power, etc.) to ensure correct reconnection. Inspect the wiring harness for any signs of damage, corrosion, or overheating that should be addressed before installing the new unit.
• Step 2: Mount the AVC63-12B2 – Position the new Basler AVR in the designated mounting location, ensuring adequate clearance for ventilation and access to adjustment potentiometers. The unit should be mounted in a location protected from excessive vibration, moisture, and heat. Secure the regulator using appropriate hardware, ensuring all mounting points are tight and the unit is properly grounded to the generator frame or electrical panel.
• Step 3: Connect Wiring According to Schematic – Following the wiring diagram provided with your AVC63-12B2 (and your generator's technical manual), connect the sensing input wires (180-264 VAC at 400 Hz), excitation output wires (to the alternator field), and any auxiliary connections for alarms or remote monitoring. Verify that all connections are tight, properly insulated, and routed away from moving parts or high-heat areas. Double-check voltage sensing connections to ensure phase-correct wiring.
• Step 4: Initial Startup and Calibration – With all connections verified, restore power to the system and start the generator under no-load conditions. Monitor the output voltage and adjust the voltage trim potentiometer on the AVC63-12B2 to achieve the desired setpoint (typically 120V or 208V depending on your system configuration). Apply incremental loads while monitoring voltage stability and regulation performance. Verify that all protection features are functioning correctly and that alarm outputs activate under appropriate fault conditions. Record all settings and maintain documentation for future reference.

Frequently Asked Questions

Q: What does the BASLER AVC63-12B2 AVR do?
A: The AVC63-12B2 is an automatic voltage regulator that continuously monitors your generator's output voltage and automatically adjusts the excitation current to the alternator's field winding to maintain stable output voltage. When loads increase or decrease, the AVR compensates in real-time to keep voltage within specified tolerances, protecting your connected equipment and ensuring reliable power delivery. This model is specifically designed for 400 Hz applications with 180-264 VAC sensing input and provides 12 Adc at 63 Vdc output for field excitation.

Q: How do I know if my AVR is failing?
A: Common symptoms of AVR failure include unstable or fluctuating generator output voltage, inability to build voltage when starting the generator, voltage that drifts high or low under load changes, overheating of the generator or regulator, or visible damage such as burnt components or discolored circuit boards. You may also experience nuisance tripping of circuit breakers, equipment malfunctions due to over-voltage or under-voltage conditions, or activation of over-excitation alarms. If you're experiencing any of these issues, the AVR should be tested or replaced by a qualified technician.
