CCC (Compressor Controls Corporation) MCP-1004 Main Processor CPU Module for Compressor Control System

Description

CCC (Compressor Controls Corporation) MCP-1004 Main Processor CPU Module for Compressor Control System

Product Core Introduction

The MCP-1004 is a rack-mounted main CPU processor board manufactured by Compressor Controls Corporation (CCC), a well-known brand for turbomachinery and compressor control. It serves as the core processing unit for CCC compressor control systems, executing anti-surge control, load sharing, speed regulation, compressor start/stop sequence, safety interlock and fault diagnostic functions. It collects analog and digital signals from field transmitters, executes high-speed closed-loop control algorithms, and communicates with local HMI, DCS/SCADA host systems via Ethernet and serial bus. This module is widely used on centrifugal compressors in oil & gas, refinery and chemical plants. This product is OEM discontinued; available stock includes fully tested refurbished and surplus spare units for legacy compressor control system maintenance.

Main Technical Specifications

Brand Same‑Series Model Recommendation

• MCP-1002: Earlier generation CCC main processor, lower processing performance.
• MCP-1008: Higher performance upgraded CPU for large multi-compressor systems.
• Triconex / Woodward turbocontrol: Alternative safety & anti-surge controllers for compressor retrofit.
• CCC UCS: Newer CCC universal control system as modern replacement for legacy MCP rack series.

Professional Quality Control Test Standard Operating Procedures (SOP)

5.1 Incoming & Visual Inspection

Inspect PCB, edge connector, front panel, soldering joints, memory chip and conformal coating. Visual check for burnt traces, swollen capacitors, bent or oxidized edge pins. Continuity and insulation test for bus interface circuits. Retain batch traceability records.

5.2 Low-Voltage Power-On Pre-Test

Insert module into CCC test rack. Power up rack, verify module boot, LED status and rack backplane communication handshake. Check for abnormal heating.

5.3 Burn-in Test

48-hour continuous powered burn-in at 40°C ambient. Simulate compressor process signals, verify anti-surge algorithm execution, interlock logic, alarm and trip response. Reject units with intermittent communication or calculation drift.

5.4 Full Functional Calibration & Parameter Test

Test analog/digital signal acquisition, sequence control, anti-surge curve calculation. Validate Ethernet / Modbus / Profibus communication, parameter save/load, event log and fault reporting. Test safety interlock trip logic.

5.5 Environmental Stress Screening

Temperature cycling (-20 ℃ ↔ +70 ℃), humidity soak and low-level vibration per IEC 60068. Recheck measurement accuracy and rack communication after stress screening.

5.6 Final Acceptance Test

Full rack integration test with CCC I/O modules and HMI. Verify real-time process data, anti-surge protection, alarm logging and host DCS data transmission. Complete appearance, label and accessory inspection before anti-static packaging.

New Module Installation Guidelines

6.1 Pre-Installation Preparation

1. Lock-out/tag-out CCC rack power supply and compressor machine.
2. Wear anti-static wristband and gloves; use anti-static mat.
3. Inspect MCP-1004 board for PCB damage; confirm firmware compatibility with existing rack, I/O modules and HMI.
4. Prepare shielded field sensor cables, Ethernet network cable.

6.2 Hardware Installation

1. Align the module with rack guide rails, insert smoothly into the empty slot and tighten front panel screws.
2. Wire pressure, temperature transmitters, solenoid valves, interlock signals to matched CCC I/O modules following CCC wiring diagram.
3. Connect Ethernet to DCS/SCADA network. Separate low-level sensor signal cables from high-power motor cables to reduce EMI noise. Ensure proper protective earth grounding.

6.3 Post-Installation Commissioning

1. Double-check module seating, wiring and grounding before power-on.
2. Power up the CCC rack, confirm MCP-1004 is recognized by rack system.
3. Use EZ-Xcaliber software to download compressor control program, anti-surge curve and alarm setpoints. Save configuration to rack.
4. Perform static signal simulation test to verify control logic and interlock trip.
5. Start compressor in manual mode, run continuous trending test for 30–60 minutes before switching to automatic anti-surge protection.

Important Safety Note: This module is critical safety control component for centrifugal compressor anti-surge protection. Wrong configuration or faulty signal may cause compressor surge and catastrophic equipment damage. Only certified CCC turbomachinery control technicians are allowed for configuration and commissioning.

FAQ (Frequently Asked Questions)

Q1: After replacement, rack cannot recognize MCP-1004 module. A1: Check module seating and edge connector oxidation. Confirm firmware compatibility between CPU and I/O modules. Reboot rack and retry.

Q2: Anti-surge calculation unstable, process reading fluctuating. A2: Check field transmitter cable shielding and grounding. Verify pressure signal wiring and I/O module health.

Q3: Compressor fails to execute safety interlock trip. A3: Verify logic configuration in EZ-Xcaliber, check interlock enable status and I/O wiring.

A4: Form factor is compatible, but firmware and resource allocation differ. Re-download control program and full interlock test after replacement.

Q5: Hot swap module allowed? A6: Not recommended. Power off the rack and perform LOTO before module replacement to avoid ESD damage and unexpected compressor trip.
