Installation Overview

Installing the Basler DECS100-B05 AVR requires careful attention to electrical connections and proper configuration to ensure optimal generator performance. Follow these general installation steps:

• Step 1: Safety Preparation and Removal – Before beginning installation, completely shut down the generator and disconnect all power sources, including battery connections. Remove the existing AVR if replacing a failed unit, carefully documenting or photographing all wire connections before disconnecting them. Verify that the DECS100-B05 is the correct replacement model by cross-referencing your generator's technical documentation or consulting the manufacturer's AVR compatibility charts.
• Step 2: Mounting and Physical Installation – Mount the DECS100-B05 in a clean, dry location within the generator control enclosure using the standard mounting configuration. Ensure adequate ventilation around the unit as AVRs generate heat during operation. Verify that the mounting location protects the regulator from excessive vibration, moisture, and temperature extremes that could affect its microprocessor-based circuitry.
• Step 3: Electrical Connections – Connect the sensing leads to the appropriate voltage tap points (100/120, 200/240, 400/480, or 600Vac) according to your generator's voltage rating and phase configuration. Connect the current transformers (5A CT secondary) for the VAR/PF controlling function, ensuring proper polarity. Wire the field output terminals to the generator's exciter field, observing correct polarity as indicated in the wiring diagram. Connect all auxiliary inputs including power supply, droop/compensation circuits, and any remote control interfaces as specified in the installation manual.
• Step 4: Configuration, Testing and Calibration – After all connections are secure and verified against the wiring diagram, restore power to the generator and perform initial startup procedures. Adjust the voltage setpoint to achieve desired output voltage using the regulator's adjustment potentiometer. Test the AVR under various load conditions to verify proper voltage regulation, and check that all protection functions operate correctly. Fine-tune settings such as stability, response time, and power factor control parameters according to your generator's characteristics and load requirements. Always consult the complete Basler DECS100-B05 installation and operation manual for detailed procedures specific to your generator model.

Frequently Asked Questions

Q: What does the Basler DECS100-B05 AVR do?
A: The DECS100-B05 Automatic Voltage Regulator is a microprocessor-based digital control device that maintains consistent voltage output from your generator regardless of load changes or engine speed variations. It continuously monitors the generator's voltage output and adjusts the excitation current to the alternator field winding, ensuring stable voltage delivery to connected equipment. The B05 model specifically includes VAR/PF controlling capability for managing reactive power and power factor, which is essential for generators supplying motor loads or operating in parallel with other power sources. This precise voltage regulation protects sensitive electrical equipment from damage caused by over-voltage or under-voltage conditions.

Q: How do I know if my AVR is failing and needs replacement?
A: Common symptoms of AVR failure include unstable generator voltage output that fluctuates significantly under load, complete loss of voltage generation (though the engine runs normally), overvoltage conditions that trip breakers or damage equipment, or failure to build voltage when the generator starts. You may also notice the generator producing voltage when unloaded but dropping excessively when load is applied. Visual inspection may reveal burned components, damaged circuit boards, or signs of moisture damage on the AVR. If you're experiencing any of these symptoms with your Basler-equipped generator, the DECS100-B05 may need replacement. Our technical team at 1-888-769-3758 can help you diagnose AVR-related issues and determine if replacement is necessary.
