Description
Product Introduction & Engineering Value
An exhaust gas temperature alarm rarely points directly to the sensor itself. In many cases, the monitoring electronics responsible for acquiring and evaluating temperature data are the real source of intermittent faults. The MAN 1689063-2 is designed to perform that supervisory function within compatible MAN engine automation systems.
The 1689063-2 Supervision M Module (ASD 0150-F) continuously processes exhaust gas temperature information used for engine protection, alarm generation, and operational monitoring. Its modular design allows replacement during scheduled maintenance while preserving the existing engine automation architecture.

Field Application & The “Trench” Experience
A chemical tanker experienced repeated high exhaust gas temperature alarms on one cylinder during ocean transit. Thermocouple measurements confirmed normal temperatures, yet the alarm persisted and occasionally triggered engine load reduction.
Maintenance personnel traced the fault to the 1689063-2 Supervision M Module, which intermittently misinterpreted sensor inputs due to an internal hardware fault. After replacing the module and verifying the monitoring channels, all exhaust temperature readings stabilized and no additional false alarms occurred during the remainder of the voyage.
Typical applications include:
- Exhaust gas temperature supervision for electronically controlled two-stroke propulsion engines
- Marine engine protection and alarm systems
- Main engine monitoring cabinets on commercial vessels

Transparency SOP: QA & Testing
Every 1689063-2 module is processed through a documented quality inspection.
- Verify the complete MAN part number, ASD 0150-F designation, and hardware revision.
- Inspect the PCB for corrosion, vibration damage, cracked solder joints, and connector wear.
- Confirm power-up operation and internal diagnostics.
- Verify signal acquisition using compatible engine monitoring equipment where available.
- Inspect communication interfaces and status indicators.
- Package the module in ESD-safe materials with reinforced shipping protection.
The Veteran’s Tech Trap Guide
⚠️ Don’t Replace Temperature Sensors First
False exhaust gas temperature alarms are not always caused by failed thermocouples. Loose terminal connections, damaged extension cables, or a defective supervision module can produce identical symptoms.
⚠️ Match the ASD Platform
Always verify that the replacement carries the correct ASD 0150-F designation and hardware revision. Similar-looking monitoring modules may have different firmware or channel configurations.
PRO TIP:
Before replacing the module, compare live temperature values across all cylinders. If multiple channels fluctuate simultaneously, the monitoring electronics are often a more likely cause than several sensors failing at once.
Dynamic FAQ
Q1. What is the function of the MAN 1689063-2?
The 1689063-2 is a Supervision M Module used to monitor exhaust gas temperature signals and provide engine protection functions within compatible MAN marine automation systems.
Q2. What does “ASD 0150-F” refer to?
ASD 0150-F identifies the supervision module platform associated with the 1689063-2 assembly and is commonly shown on the module identification label.
Q3. Can this module be installed as a direct replacement?
In most service applications, yes, provided the part number, hardware revision, and system configuration match the original installation.
Q4. Is this module used only for exhaust gas temperature monitoring?
Its primary documented application is exhaust gas temperature supervision, although it operates as part of the broader MAN engine monitoring and protection system.
Q5. Is New Surplus inventory available?
Yes. Depending on market availability, suppliers commonly offer New Surplus, professionally refurbished, and exchange-repaired 1689063-2 modules. Functional verification before shipment is recommended.
Q6. What should be checked before replacing the module?
Inspect thermocouples, extension cables, terminal blocks, control power quality, and diagnostic logs before replacing the module. Many apparent module failures are ultimately traced to field wiring or sensor circuit issues rather than the electronics themselves.
