Installation Overview

Installing the Basler DECS100-B15 AVR requires careful attention to electrical connections and system configuration. Here's a general overview of the installation process:

• Step 1 - Power Down and Disconnect: Begin by completely shutting down the generator and disconnecting all power sources. Lock out and tag out the system according to your facility's safety procedures. Remove the existing AVR carefully, documenting all wire connections with photographs or detailed notes. Pay special attention to sensing leads, exciter field connections, CT connections, and control wiring.
• Step 2 - Mounting and Mechanical Installation: Mount the DECS100-B15 in the designated location using appropriate hardware. Ensure adequate ventilation around the unit as specified in the installation manual. The regulator should be mounted in a clean, dry environment away from excessive vibration, moisture, and contaminants. Verify that the mounting surface is secure and that the unit is properly grounded.
• Step 3 - Electrical Connections: Connect the sensing leads to the appropriate generator terminals according to your voltage configuration (single-phase or three-phase). Connect the exciter field output wires (F+ and F-) to the generator's excitation system. If your system uses current transformers for VAR/PF control (as the B15 variant supports), connect the 5A CT secondary wiring to the designated terminals. Connect any auxiliary control inputs such as remote voltage adjust, droop compensation, or external control signals.
• Step 4 - Configuration and Startup: Before energizing the system, verify all connections against the wiring diagram. Set the internal jumpers and switches according to your generator's voltage and frequency specifications. Power up the system and follow the startup procedure outlined in the Basler manual, which includes setting voltage regulation levels, adjusting stability parameters, and calibrating VAR/PF control functions. Perform a load test to verify proper voltage regulation under various load conditions. Always consult the manufacturer's installation and operation manual for detailed procedures specific to your application, and consider having a qualified Basler technician or authorized service provider perform or supervise the installation for optimal results.

Frequently Asked Questions

Q: What does the DECS100-B15 AVR do for my generator?
A: The DECS100-B15 automatic voltage regulator continuously monitors your generator's output voltage and automatically adjusts the excitation current to the alternator's field windings, maintaining stable voltage output regardless of load changes. The B15 variant specifically adds VAR/PF control for power factor correction and reactive power management, voltage matching for paralleling multiple generators, and 5A CT compatibility for current sensing applications. This ensures your generator delivers clean, consistent power that protects connected equipment from damage caused by voltage fluctuations.

Q: How do I know if my AVR is failing and needs replacement?
A: Common symptoms of a failing AVR include erratic voltage output that swings high or low, inability to maintain set voltage under load, generator overheating due to excessive excitation, flickering lights or equipment shutdowns, and visible damage such as burned components or error codes on digital displays. You may also notice the generator fails to build voltage on startup or loses voltage regulation during operation. If you're experiencing any of these issues, the DECS100-B15 may be the replacement solution you need. Our technical team at 1-888-769-3758 can help diagnose your specific situation.
