Overview
The Consilium SW2020 fixed gas detection system is built around its main processor PCB — the central intelligence board that manages all system functions: detector channel monitoring, alarm threshold evaluation, relay output control, display communication, and system self-diagnostics. When the main processor PCB fails, the entire SW2020 system stops functioning. Unlike a display component failure that affects only the operator interface while the underlying detection may continue, a main processor PCB failure takes the fixed gas detection system completely offline — with immediate implications for the vessel’s gas detection compliance status and operational safety.
The Main Processor PCB and Main Processor EPROM for the Consilium SW2020 provides the two core processor components required to restore a failed SW2020 main processor assembly to full operational status. The processor PCB (IKK-4, Art.nr 052000, Rev.RIA, SLE 2335002) and the processor EPROM (AKK-2, Art.nr 052000, Rev.RIB, SLE 2336001) are supplied together as a matched pair — ensuring the EPROM firmware revision is compatible with the processor PCB revision for correct system operation after installation.
What makes this component pair the appropriate choice for SW2020 main processor restoration is the verified SLE reference matching for both components. The IKK-4 processor PCB (SLE 2335002) and the AKK-2 EPROM (SLE 2336001) are both referenced in the SW2020 spare parts schedule with individual SLE numbers — confirming that both components are OEM-referenced spare parts for the SW2020 platform, not generic alternatives. For marine engineers and vessel operators who need to restore SW2020 main processor functionality with confidence in firmware-hardware compatibility, a matched OEM-referenced processor PCB and EPROM pair supplied together eliminates the risk of firmware-hardware revision mismatch that can occur when the two components are sourced separately from different suppliers.
Key Features
Matched Processor PCB and EPROM Pair — Firmware-Hardware Compatibility Assured
The IKK-4 processor PCB (Rev.RIA) and AKK-2 EPROM (Rev.RIB) are supplied together as a matched pair with confirmed revision compatibility. This is operationally important: an SW2020 main processor PCB installed with an EPROM of an incompatible firmware revision may exhibit unpredictable behaviour, fail to initialise correctly, or produce system errors that are difficult to diagnose without the revision compatibility knowledge that comes from sourcing both components from a specialist supplier. Supplying the PCB and EPROM as a matched pair removes that compatibility uncertainty from the maintenance process.
IKK-4 Processor PCB — Art.nr 052000, Rev.RIA, SLE 2335002
The IKK-4 processor PCB carries Consilium article number 052000, revision RIA, and SLE reference 2335002 — the manufacturer’s complete part identification for the SW2020 main processor board. The Rev.RIA designation confirms the specific hardware revision of the processor PCB, which is relevant for determining compatibility with the EPROM firmware revision and with other system PCBs in the SW2020 assembly. The SLE 2335002 reference provides the spare parts schedule identification for ISM Code maintenance documentation and class survey records.
AKK-2 EPROM — Art.nr 052000, Rev.RIB, SLE 2336001
The AKK-2 EPROM carries Consilium article number 052000, revision RIB, and SLE reference 2336001 — the manufacturer’s identification for the SW2020 main processor firmware component. The EPROM contains the SW2020 system firmware that controls all system functions — detector channel management, alarm logic, relay output sequences, display communication protocols, and system self-test routines. An EPROM with the correct firmware revision is essential for correct system operation after processor PCB replacement. The Rev.RIB designation on the AKK-2 EPROM is matched to the Rev.RIA IKK-4 PCB for confirmed compatibility.
Refurbished Condition — Inspected and Tested
Both components are supplied in refurbished condition — inspected and tested for functionality before supply. For main processor components where operational reliability is directly linked to full system functionality, tested refurbished condition is the appropriate supply standard. For SW2020 systems that may be 15–25 years into their service life, refurbished OEM-referenced components provide a cost-effective and often more immediately available alternative to new OEM components that may be on extended lead time or discontinued from the manufacturer’s active product line.
Dual SLE References — Complete Spare Parts Documentation
The two separate SLE references — SLE 2335002 for the IKK-4 PCB and SLE 2336001 for the AKK-2 EPROM — allow each component to be individually recorded in the vessel’s spare parts inventory against the SW2020 SLE spare parts list. For vessels maintaining spare parts records under ISM Code requirements, individual SLE references for each component provide accurate inventory documentation and support the maintenance records required for class society annual surveys and port state control inspections of the vessel’s safety management system documentation.

Benefits
Complete processor restoration in a single procurement — PCB and matched EPROM together. Sourcing the main processor PCB and EPROM as a matched pair from a single supplier eliminates the revision compatibility risk that arises when the two components are sourced separately and may come from different SW2020 system generations with incompatible firmware-hardware combinations. One procurement, one confirmed compatible pair, one installation — with the correct system operation after.
Restores full SW2020 system functionality from a complete processor failure. A main processor PCB failure takes the entire SW2020 system offline. Replacing the processor assembly with the correct matched components restores all system functions — detector channel monitoring, alarm evaluation, relay output control, and display communication — returning the vessel’s fixed gas detection system to full operational status and compliance.
OEM-referenced components with verified SLE numbers support maintenance documentation. Both components carry individual Consilium SLE references (2335002 and 2336001) that can be recorded in the vessel’s spare parts inventory and maintenance records. For vessels operating under ISM Code requirements where safety system maintenance documentation is subject to class and flag state survey inspection, correct SLE-referenced spare parts records are a documentation compliance requirement.
Refurbished availability for legacy SW2020 systems where new OEM stock may be limited. For SW2020 systems installed in the 1990s and 2000s, new main processor PCBs may be discontinued from active production or available only on extended lead time from the manufacturer. Refurbished OEM-referenced components available through a specialist supplier provide a practical maintenance pathway for keeping these installed systems operational without the delay and cost of new OEM sourcing or the risk of full system replacement.
Dual article number 052000 for both PCB and EPROM — simplified procurement reference. Both the IKK-4 PCB and AKK-2 EPROM share the same Consilium article number 052000, which can cause confusion in procurement documentation for engineers unfamiliar with the SW2020 spare parts structure. The individual SLE references (2335002 for PCB, 2336001 for EPROM) provide the unambiguous identification that allows each component to be correctly specified in purchase orders and maintenance records.
Who It’s For
The Marine Electronics Engineer or Ship’s Electrical Officer Dealing with a Complete System Failure
Your vessel’s SW2020 fixed gas detection system has failed completely — no display, no alarm response, no system activity. Diagnosis points to the main processor PCB. You need to source both the processor PCB (IKK-4) and the matching EPROM (AKK-2) with the correct revision combination to restore the system. You need a supplier who understands the SW2020 processor architecture, can confirm the revision compatibility of the PCB and EPROM pair, and can supply both components with verified SLE references for your maintenance records. Alright Engineering Solutions provides exactly that sourcing capability.
