DECS-200 Setup 6-1
SECTION 6 • SETUP
INTRODUCTION
This section provides generic setup and operation procedures for excitation systems using the DECS-
200. These procedures are provided only as a guide and are not intended as a replacement for the setup
and operation procedures required by a specific system. In these procedures, DECS-200 settings are
entered through the BESTCOMS interface. Therefore, a PC operating with BESTCOMS software will
need to be connected to the DECS-200 being configured. For information about using BESTCOMS, refer
to Section 5,
BESTCOMS Software .
Equipment Required
The following equipment is required to perform the procedures presented here:
• Two-channel chart recorder or the DECS-200’s oscillography. First channel measures the generator
voltage at DECS-200 terminals A1 (E1) and A3 (E3). Second channel measures the field voltage at
DECS-200 terminals C5 (F+) and C6 (F–).
• Oscilloscope
• Personal computer (PC) running BESTCOMS. The minimum requirements for a PC running
BESTCOMS are provided in Section 5,
BESTCOMS Software .
• Nine-pin serial communication cable to connect the DECS-200 to the PC.
