What it represents
Converts a monitored mechanical condition into an electrical alarm or protection signal.
In a drafting package, connect this reference to the mechanical sensor and measurement channel. The associated drawing should trace the monitor output and machine shutdown logic; the number identifies the role and does not specify the terminal arrangement, ratings or operating settings.
How to read it
- Identify the mechanical sensor and measurement channel.
- Trace the monitor output and machine shutdown logic.
Information to show or reference
- Label the mechanical sensor and measurement channel.
- Cross-reference the monitor output and machine shutdown logic.
- Identify the device tag, manual revision and logic drawing that define this implementation.
A distinction that matters
Mechanical monitoring is not electrical current-unbalance protection, even when both protect the same machine.
