INTRODUCTION
This instruction manual provides information about the operation and installation of the DECS-100 Digital
Excitation Control System. To accomplish this, the following information is provided:
• General Information and Specifications
• Controls and Indicators
• Functional Description
• Installation
• Maintenance and Troubleshooting
WARNING!
To avoid personal injury or equipment damage, only qualified personnel should
perform the procedures in this manual.
Lethal voltage is present at the rear panel when the unit is energized. Rear panel
connections should be made only when the unit is de-energized.
NOTE
Be sure that the DECS-100 is hard-wired to earth ground with no smaller than 12
AWG copper wire attached to the ground terminal on the rear of the unit case.
When the DECS-100 is configured in a system with other devices, it is
recommended to use a separate lead to the ground bus from each unit.
CAUTION
The Manual mode excitation level must be evaluated prior to enabling this
feature. If the level of excitation current is inappropriate for the generator, severe
damage to the generator may occur.
Improper PID numbers will result in poor system performance or system damage.
When applying operating power for programming purposes, observe the pre-
cautions called out in Section 4, Installation, Preliminary Setup.
When programming the DECS-100 without the generator spinning, the
connections to DECS-100 terminals F+ and F– should be removed.
Before uploading a settings file, remove operating power from the DECS-100,
disconnect the field wiring from terminals F+ and F–, and re-apply operating
power to the DECS-100.
