What it represents
Introduces a deliberate interval before a starting or closing operation is permitted.
In a drafting package, connect this reference to the initiating contact and timer supply. The associated drawing should trace the delayed start or close command; the number identifies the role and does not specify the terminal arrangement, ratings or operating settings.
How to read it
- Identify the initiating contact and timer supply.
- Trace the delayed start or close command.
Information to show or reference
- Label the initiating contact and timer supply.
- Cross-reference the delayed start or close command.
- Identify the device tag, manual revision and logic drawing that define this implementation.
A distinction that matters
Device 2 delays starting or closing; device 62 delays a stopping or opening action.
