Installation and Integration Overview

Installing the D700 II automatic voltage regulator requires basic electrical knowledge and adherence to proper safety procedures. Before beginning any installation work, always disconnect the generator from all power sources and follow lockout/tagout protocols. The D700 II mounts in the standard AVR position on LEROY SOMER alternators, utilizing existing mounting holes and connection points.

Installation Steps Summary:

• Power down the generator completely and ensure all stored energy is discharged
• Remove the alternator end cover to access the existing AVR mounting location
• Disconnect all electrical connections from the old voltage regulator, noting wire positions
• Remove mounting hardware and extract the failed or obsolete AVR unit
• Position the new D700 II AVR in the mounting location, aligning with mounting holes
• Secure the voltage regulator using appropriate hardware with proper torque specifications
• Reconnect all electrical connections according to the wiring diagram (sensing, excitation, power)
• Verify all connections are tight and properly insulated
• Replace the alternator end cover and ensure proper ventilation clearances
• Perform initial startup procedures and voltage adjustment as needed

After installation, the D700 II should be calibrated to achieve the desired output voltage. Use a calibrated multimeter to measure generator output voltage under no-load conditions, then adjust the voltage trim potentiometer to achieve the target voltage (typically 400V or 480V three-phase, depending on your system). Load testing should be performed to verify proper voltage regulation across the full load range. For complex installations or if you're unfamiliar with generator systems, we strongly recommend professional installation by a qualified electrician or generator technician.

Frequently Asked Questions About the LEROY SOMER D700 II AVR

Q: How do I know if my generator needs an AVR replacement?

A: Common symptoms of AVR failure include erratic voltage output, inability to maintain stable voltage under load, overvoltage or undervoltage conditions, no generator output voltage, or visible damage to the AVR circuit board. If your generator's voltage fluctuates significantly or you're experiencing power quality issues, the automatic voltage regulator is often the culprit. The D700 II can be tested with a multimeter and oscilloscope, but replacement is often the most cost-effective solution when faults are detected.

Q: Is the D700 II compatible with my specific KOHLER or SDMO generator model?

A: The D700 II is designed for 560 kW and 700 kVA generator systems from SDMO and KOHLER that utilize LEROY SOMER alternators. To verify compatibility, check the model plate on your existing AVR or consult your generator's technical documentation. The General Power team can also assist with compatibility verification if you provide your generator model number and serial number. The D700 II replaces original D700 II units and certain D700 variants.

Q: Can I install the D700 II AVR myself, or do I need a professional?

A: Installation of the D700 II requires working with live electrical components and understanding of generator systems. If you have electrical experience and are comfortable working with power generation equipment, installation is straightforward following proper safety procedures. However, if you're unfamiliar with generator maintenance or electrical systems, we strongly recommend hiring a qualified generator technician or electrician. Improper installation can damage the AVR, alternator, or connected equipment, and may void warranties.

Q: What is the typical lifespan of a LEROY SOMER D700 II automatic voltage regulator?

A: Under normal operating conditions with proper maintenance, the D700 II AVR can provide 10-15 years of reliable service. Lifespan depends on factors including operating environment, load characteristics, maintenance practices, and environmental conditions. Generators operating in harsh environments (extreme temperatures, high humidity, dust, or vibration) may experience shorter AVR life. Regular inspection and maintaining clean, well-ventilated alternator compartments extend AVR longevity. Surge protection and proper grounding also protect the voltage regulator from premature failure.

Q: Does General Power offer technical support for D700 II installation and troubleshooting?

A: Yes, General Power provides comprehensive technical support for all products we sell, including the LEROY SOMER D700 II AVR.
