Pre-Commissioning Preparation
Implement Lockout/Tagout (LOTO) procedures to cut all power to the Mark V control cabinet. Confirm residual voltage is fully dissipated, and keep the turbine offline throughout commissioning activities.
Wear a grounded ESD wrist strap at all times. Hold the PCB only by its edges; avoid contact with integrated circuits, solder joints and gold-plated connectors.
Capture photos and document all jumper positions on the original board. Set the 15 on-board jumpers according to recorded data for voltage/current signal modes and burden resistor configuration.
Conduct visual inspection on terminal blocks, ribbon cable ports and backplane connectors for bent pins, oxidation and contaminants. Clear any impurities when discovered.
Confirm the part suffix complies with site requirements to prevent TMR voting faults across R/S/T control cores.
Wiring & Hardware Check
Run shielded field cables to TB1 and TB2 terminal blocks. Wire all analog transmitters (4–20mA / 0–10VDC) strictly in accordance with engineering drawings. Fasten terminal screws with appropriate torque to avoid loose connections.
Attach ribbon cables to matching inter-board connectors and ensure cable latches engage securely. Route cables to eliminate tensile stress and abrasion induced by vibration.
Cross-verify all jumper setups, field wiring and inter-board cable assignments against technical schematics. Ensure no short circuits or stray conductive materials exist inside the cabinet.
Power-On Initial Inspection
Remove LOTO devices and restore cabinet power incrementally. Measure backplane supply voltage to maintain stable 18–32 VDC (nominal 28 VDC). Record the typical board operating current of approximately 0.35 A.
Employ a multimeter to test isolation between signal circuits and the backplane; insulation performance must satisfy the 250 VAC isolation specification.
Analog Signal Loop Testing
Inject standard simulated analog signals (4mA, 12mA, 20mA, ±10VDC) into each field terminal channel.
Track corresponding signal values via Mark V Toolbox software on TCQA control boards. Validate precise signal transmission without offset, distortion or electrical noise.
Perform testing on all analog output loops. Verify output signals transmitted from control boards reach field devices properly via TBQB terminals.
Inspect channel overcurrent protection and confirm continuous current for each channel stays below 25mA.
System Redundancy & Voting Test
Execute signal consistency tests for triple redundant R/S/T cores. Ensure consistent signal readings among three core racks to avoid voting discrepancies.
Simulate slight signal variations to verify reliable signal transmission between field instruments and main control boards. Guarantee no false alarms are generated by termination circuits.
Post-Commissioning Documentation
Document final jumper layout, terminal wiring schematics and all signal test results. File these records for future maintenance use.
Implement continuous monitoring for a minimum of one operational cycle. Watch out for intermittent signal drift or unstable measurements caused by poor terminal contact.
Critical Warnings
Never insert or remove the board under energized conditions; hot swapping may cause system failures and unexpected turbine trips.
Misconfigured jumpers will disrupt voltage-current signal conversion and lead to measurement errors.
Maintain adequate ventilation around the board. Excessive heat accelerates terminal oxidation and premature component deterioration.
