Functional Description of DS200DCFBG1BJB
The DS200DCFBG1BJB receives 38 V ac (or 24 V dc) from the control power transformer. This input is full-wave rectified and filtered to produce unregulated ±24 V dc outputs. Linear regulators then derive ±15 V dc, and a switching regulator generates the +5 V dc output. The DS200DCFBG1BJB also produces isolated +5 V and ±15 V dc for armature current feedback circuits.
The DS200DCFBG1BJB includes multiple voltage-controlled oscillator (VCO) circuits that convert analog signals (armature current, field current, AC line voltage, DC bridge voltage) into frequency signals sent to the SDCC/LDCC board via connector 1PL. These signals are used for commutation failure detection, AC instantaneous overcurrent (IOC), phase sequence monitoring, and SCR firing control.
A gate array on the DS200DCFBG1BJB controls SCR firing based on signals from the SDCC/LDCC board. The gate array is programmed at power-up by a serial PROM. To prevent spurious firing, firing power is removed until programming is complete and +5 V is regulated.
Motor Voltage Attenuation and AC Line Monitoring
The DS200DCFBG1BJB includes a motor voltage attenuation circuit that provides an analog representation of motor voltage (0–5 V, biased at 2.5 V) to the SDCC/LDCC board via 1PL-6. DIP switch SW6 scales this feedback.
Amplifier circuits on the DS200DCFBG1BJB process AC line-to-line voltages for phase loss detection, synchronization, and SCR failure detection. DIP switches SW1, SW2, and SW3 scale these feedbacks.
AC Line Current Transformer Interface
For applications using AC line current transformers (ACCTs) on L1 and L3, the DS200DCFBG1BJB uses switch SW7 to select burden resistance based on rated 1 pu DC output current. The ACCT signals are sent to the SDCC/LDCC board via 1PL for commutation failure and IOC monitoring. Testpoint ACCT allows signal viewing.
Jumper and Switch Configuration for DS200DCFBG1BJB
The DS200DCFBG1BJB includes 12 configurable jumpers (JP1 to JP12) and seven DIP switches (SW1 to SW7). All jumpers and switches on the DS200DCFBG1BJB must be set identically to the board being replaced unless otherwise instructed. Factory settings are provided on test data sheets supplied with each controller.

Critical DIP Switch Settings
Switch | Function | Example Settings |
SW1, SW2, SW3 | AC line voltage scaling (V1-2, V2-3, V1-3) | 0 (off) = 308 V max nominal; 2 (2 on) = 617 V max nominal; use SHVI/SHVM attenuators above 617 V |
SW4 | DC bridge voltage feedback VCO scaling | Same voltage ranges as SW1–SW3 |
SW5 | DC motor voltage feedback VCO scaling | Same as SW4 |
SW6 | Analog DC motor voltage feedback scaling | 0 = 154 V ac / 171 V dc; 7 = 630 V ac / 697 V dc |
SW7 | AC line CT burden selection (15 positions) | Based on CT secondary current (mA). Example: 0 = <6.0 mA; 15 = 137–144 mA |
Note: For DC2000 and EX2000 applications, SW1 through SW6 on the DS200DCFBG1BJB must all be set to the same position. For GF2000/ME2000, SW1–SW4 share one setting, while SW5 and SW6 may differ.

Protection and Status Indication
The DS200DCFBG1BJB protects downstream circuits with three fuses:
FU1 (1/2 A, 2AG fast-acting) – Protects the 115 V ac output (customer use or fans). When blown, neon lamp LT1 lights.
FU2 (7 A, 2AG) – Protects +24 V, +15 V, and +5 V dc lines. When blown, red LED CR51 lights.
FU3 (7 A, 2AG) – Protects -24 V and -15 V dc lines. When blown, red LED CR55 lights.
The /PSEN signal (on 2PL-1) goes low when +5 V dc is in regulation; if +5 V goes out of regulation, /PSEN goes high and triggers a microprocessor reset on the SDCC/LDCC board.
Replacement Procedure for DS200DCFBG1BJB
When replacing a DS200DCFBG1BJB, follow these steps (per GEI-100028C):
Turn off all power to the drive and wait several minutes for capacitors to discharge. Verify no voltage present with a meter.
Open the cabinet door and access the board carrier. The DS200DCFBG1BJB is normally mounted behind the drive control card.
Release lock tabs on either side of the board rack and tilt the front board carrier forward.
Carefully disconnect all cables from the DS200DCFBG1BJB:
For ribbon cables, grasp the sides of the cable connector and gently pull.
For cables with pull-tabs, pull the tab carefully.
Push back on plastic snaps (holders) to release the DS200DCFBG1BJB from the board carrier.
Critical: Set all jumpers and DIP switches on the new DS200DCFBG1BJB exactly as they were on the old board. Use GEI-100028C Tables 1 and 2 for revision differences.
Orient the new DS200DCFBG1BJB in the same position and install it onto the board carrier. Ensure all plastic snaps secure the board.
Reconnect all cables as labeled, ensuring proper seating at both ends.
Adjust EE parameter EE.574 (VFB0FS) – voltage feedback offset – using a programmer board, ST2000, GE Control System Toolbox, or LynxOS Configurator.
Swing the front board carrier back into position, lock the tabs, and close the cabinet door.
EE Parameter Adjustment for DS200DCFBG1BJB
After installing a DS200DCFBG1BJB, the voltage feedback offset parameter EE.574 (VFB0FS) must be adjusted. The method depends on the application (DC2000, CB2000, EX2000, FC2000, GF2000, ME2000, or AC2000 IGBT drive). Refer to the applicable drive instruction book for the detailed adjustment procedure.
