Installation and Setup Overview

Installing the DECS100-B15 automatic voltage regulator requires basic electrical knowledge and familiarity with generator systems. Professional installation by a qualified electrician or generator technician is strongly recommended to ensure proper operation and maintain warranty coverage. The installation process typically involves:

Pre-Installation Preparation: Before beginning installation, verify that the replacement AVR matches the specifications of the original unit. Ensure the generator is completely shut down, disconnected from all power sources, and properly locked out/tagged out according to safety protocols. Review the Basler installation manual specific to your generator model and gather necessary tools including appropriate screwdrivers, wire strippers, and a digital multimeter for testing.

Mounting and Physical Installation: The DECS100-B15 mounts in a standard panel cutout, typically located on the generator control panel. Remove the old regulator by disconnecting all wiring (photograph connections first for reference) and unscrewing mounting hardware. Clean the mounting area and install the new DECS-100-B15, ensuring proper alignment and secure fastening. Verify adequate ventilation around the unit as the regulator dissipates heat during operation.

Electrical Connections: Connect power input, sensing lines, exciter field output, and control signals according to the wiring diagram. The DECS100-B15 features clearly labeled terminals for: AC sensing inputs (voltage sensing from generator output), CT inputs (current transformer connections for load sensing in paralleling applications), exciter field output (F+ and F- terminals connecting to the alternator exciter), and auxiliary inputs/outputs for remote voltage adjustment, droop CT connections, and control signals. Use appropriate wire gauges and ensure all connections are tight and properly terminated.

Configuration and Testing: After wiring is complete, configure the AVR settings including voltage sensing range, control mode (VAR, PF, or voltage droop), and protection parameters according to your specific application requirements. Start the generator and verify proper voltage regulation across no-load and loaded conditions. Test all control functions including voltage adjustment, parallel operation (if applicable), and protective shutdown features.

Frequently Asked Questions About the BASLER DECS100-B15

Q: What is the difference between the DECS100-B15 and other DECS-100 models?

A: The B15 designation specifically indicates this model includes VAR/PF (reactive power/power factor) control capability, voltage matching functionality, and compatibility with 5A CT secondary current transformers. These features make the DECS100-B15 ideal for generator paralleling applications where multiple units must share load and manage reactive power. Other DECS-100 variants may lack these advanced paralleling features or use different CT ratios. Always verify the exact model suffix to ensure you're ordering the correct regulator for your application.

Q: Can the DECS100-B15 replace my older Basler voltage regulator?

A: In many cases, yes, but compatibility verification is essential. The DECS-100-B15 can often replace older Basler models including some DECS-50 variants and legacy analog regulators, but you must ensure matching specifications including output voltage/current capacity, sensing voltage range, and control features. The physical mounting dimensions and wiring terminal configurations may also differ between regulator generations. Consult your generator documentation or contact General Power's technical team for compatibility confirmation before ordering.

Q: What size generator can the DECS100-B15 control?

A: The DECS-100-B15 is rated for generators up to 5MW (5000kW) capacity. The regulator provides 63VDC at 7.0A continuous output, which supplies sufficient excitation power for brushless alternators in this power range. For smaller generators (under 500kW), the DECS100-B15 may be overspecified, though it will function correctly. For generators exceeding 5MW, consult Basler Electric's product lineup for higher-capacity regulators designed for larger alternators.

Q: Do I need special tools or training to install the DECS100-B15 AVR?

A: Installation requires electrical knowledge and familiarity with generator systems. While the physical installation is straightforward for qualified technicians, proper wiring of sensing lines, exciter field connections, CT inputs, and control signals is critical for safe, reliable operation. We strongly recommend professional installation by a licensed electrician or certified generator technician. Improper installation can damage the regulator, harm the generator, or create safety hazards.
