Frequently Asked Questions

What should I do if the CCM-30 module displays a communication fault LED on startup?

Verify the CAN-bus termination resistors (typically 120 ohms) at both ends of the network string and check the continuity of the redundant RS-485/CAN communication wiring. Ensure the 24V DC input voltage is stable and free from voltage drops.

Is the PAAF725952 backward compatible with older CCM-20 revisions?

No. The CCM-30 features updated internal processing speeds, updated firmware protocols, and distinct I/O mapping matrices that require proper configuration through the Wärtsilä service tool suite when upgrading from legacy hardware tiers.

Can this unit be configured for non-marine industrial applications?

Yes. The CCM-30 is identical in hardware configuration to units used in land-based Wärtsilä power plants, provided the application software matches the prime mover’s operational parameters.
