3. Chassis Internal & External Structure Description

1. Front Area

• Multi-position VME card slot openings with locking screw reserved holes for each module

• Fan running status indicator light and over-temperature alarm signal terminal

• Front door with transparent dust-proof window, quick-release lock for easy module maintenance

2. Rear Area

• External DC power input terminal block with positive/negative polarity marking

• Signal wiring cable outlet holes with rubber anti-abrasion sealing rings

• External alarm signal output terminals for connecting cabinet HMI alarm system

3. Internal Layout

• Central VME gold-plated backplane, independent power distribution area on the bottom layer

• Side forced air cooling fans and directional ventilation air ducts for uniform heat dissipation

• Metal shielding partitions separating power area and signal bus area to reduce interference

4. Auxiliary Accessories

• Module fixing screws, cable binding brackets, dust filter cotton for fan air inlet

4. Standard Installation Operating Procedures

1. Connect external DC power supply cable to rear power input terminal, strictly distinguish positive and negative poles, tighten terminal screws;

2. Lead all module external signal cables out through rear wire-through holes, install rubber sealing rings to prevent dust and moisture from entering the chassis;

3. Connect over-temperature alarm signal cable to rear alarm terminals and link to upper monitoring alarm system.

   Step 4 Module Insertion Sequence

4. Insert heavy heat-generating boards (UCVD main control, S200 DSP) into middle slots close to cooling fans for priority heat dissipation;

5. Install I/O termination boards, communication PMC cards and servo signal boards in remaining slots one by one, tighten front panel locking screws for each module;

6. Reserve 1–2 empty slots as maintenance spare positions.

   Step 5 Pre-Power-On Comprehensive Inspection

   Check all power terminals without short circuit, all VME modules fully inserted into backplane slots, fan air inlet filter cotton installed intact without blockage. Confirm no metal debris left inside the chassis before power supply switching on.

   Step 6 Power-On Commissioning & Acceptance

   Switch on external DC power supply. Observe fan run indicator light steady on, no over-temperature alarm output. Insert all control modules and complete system communication test; verify all boards obtain stable bus power and normal data interaction. Installation acceptance is passed after chassis temperature remains stable under full-load continuous operation.

5. Daily Operation & Regular Maintenance Standards

1. Normal Operation Judgment Standard

   Cooling fans run smoothly without abnormal noise; chassis temperature maintains within 0~60℃ without over-temperature alarm; all VME modules operate normally without bus communication failure.

2. Regular Inspection Checklist

• Shift Inspection: Check fan running indicator, confirm no over-temperature alarm signal output;

• Monthly Maintenance: Take out fan filter cotton and clean dust with compressed air blower; check fan rotation smoothness;

• Quarterly Inspection: Retighten rear power and signal wiring terminals, clean dust on VME backplane connectors, inspect shell anti-corrosion coating integrity.

3. Environmental Maintenance

   Keep the outer control cabinet fully sealed and equipped with dehumidifier, avoid corrosive gas, conductive dust and water vapor entering the VME chassis interior.

6. Common Fault Diagnosis & Troubleshooting

7. Mandatory Safety Operation Precautions

1. Cut off external DC input power of the entire chassis before opening front door, disassembling modules or maintaining internal wiring, to avoid electric shock and system bus short-circuit risk.

2. Only matched GE original VME modules and certified shielded cables are allowed to be installed and wired inside the chassis; non-standard accessories will cause bus communication failure and void warranty.

3. Stop turbine control system operation immediately and cut off chassis power supply if over-temperature alarm cannot be eliminated; long-term high temperature will cause permanent burnout of all internal control boards.

4. Unauthorized disassembly of chassis metal shielding frame and internal backplane components is prohibited; damage caused by private disassembly is not covered by warranty.

5. Adopt shockproof and dust-proof packaging during transportation and storage; avoid heavy collision and extrusion to prevent backplane connector deformation.

6. This chassis carries turbine safety critical control hardware. All internal module replacement, wiring and maintenance must be operated by certified GE industrial control technicians with turbine safety qualification.

8. Long-Term Standard Storage Requirements
