Note 1: The above table lists series names. Ask your OMRON representative for details on specific model numbers.
Note 2: For type approvals, these models shall not be installed on the deck, in the bridge, or on machinery that has severe vibration conditions.
Type approval of the ABS (American Bureau of Shipping) was made according to the Steel Vessel Rules.
Refer to the following table for system categories.
TABLE 1
Assignment to System Categories by Effects of Failure (2008)
System Category Effects of Failure
I Failure will not lead to dangerous situations for human safety, safety of the vessel and/or threat to the environment.
II Failure could eventually lead to dangerous situations for human safety, safety of the vessel and/or threat to the environment.
III Failure could immediately lead to dangerous situations for human safety, safety of the vessel and/or threat to the environment.
Notes:
1. Consideration is to be given to the extent of the damage directly caused by a failure.
2. The assignment of a computer-based system to the appropriate system category is to be made according to the greatest
likely extent of direct damage.
3. Where independent effective backup or other means of averting danger is provided the system category may be decreased.
