MSC failure alarm occurs (configured as warning or electrical trip); MSC TOO FEW SETS alarm triggers; Affected genset declares 'MSC ID ERROR'; Electrical trip on the affected set; Affected modules display 'MSC DATA ERROR'; Operation of the MultiSet system is not possible; MSC failure alarm occurs (configured as a warning or electrical trip)
Possible Causes
- •The number of modules communicating on the Multiset communications link falls
- •The number of modules on the communications link falls below the 'Minimum modules on Multiset comms link' configurable setting
- •Two or more gensets have the same MSC ID
- •Data is corrupted on the MultiSet Communications link
- •Incorrect wiring used between the modules
- •MSC terminator is incorrectly enabled on non-end units or not enabled on end units
- •Maximum cable run distances are exceeded
Suggested Actions
- 1Increase the number of communicating modules on the Multiset communications link to automatically clear the warning alarm and reconfigure communicating modules
- 2Configure and activate a module digital input to disable the MSC failure alarm
- 3Increase the number of communicating modules on the Multiset communications link
- 4Adjust the 'Minimum modules on Multiset comms link' configuration setting in the module
- 5Set the correct ID using the PC configuration software
- 6Commission units starting with ID 1, 2, 3 etc. and configure spare modules as 16, 15 etc. to avoid conflicts
- 7Ensure correct wiring is used between the modules
- 8Enable the MSC terminator on only the end units on the link
- 9Ensure maximum cable run distances are not exceeded
