Installing a DS200TCQCG1A: What to Copy From the Old Board
The TCQC's 24 jumpers don't need reconfiguring every time the board is replaced — once set during original commissioning, they stay stable. That means the task, when replacing a faulty board, is straightforward: place the old board next to the new one on a clean surface, wearing an anti-static wrist strap, and physically replicate each jumper position before energizing it. Don't try to guess the configuration from a generic manual — every installation has its own settings defined alongside the plant's engineering team.
What This Board Does
The DS200TCQCG1A works in position 4 of the <R>, <S>, and <T> cores, supplementing the TCQA (position 2) and, when present, the TCQB (position 3). It supplies the excitation voltage required by the position LVDTs and performs the digital-to-analog conversion representing the fuel flow requested by the control system — and it doesn't function without the TCQA (and TCQB) on the same core operating correctly.
Diagnose Before You Buy
- If the symptom involves unstable LVDT excitation or an incorrect fuel-flow calculation, first confirm the health of the TCQA on the same core.
- For out-of-spec voltage alarms, check the core power supply's fuses before any board swap — and confirm the system's calibration file matches the board and PROM revisions actually installed.
- Physically confirm the application actually uses a TCQC before finalizing the order.
