ANSI/IEEE Solenoid-valve NC auxiliary contact form
IEEE-library form of solenoid-valve nc auxiliary contact: this form identifies a normally-closed auxiliary contact associated with a solenoid valve.
In plain English
What does ANSI/IEEE Solenoid-valve NC auxiliary contact form mean?
This reference locates solenoid-valve nc auxiliary contact in Autodesk's IEEE-oriented solenoids family. This form identifies a normally-closed auxiliary contact associated with a solenoid valve. The public library uses HSV22 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence.
What the drawings help you do
State the reference condition used to describe the contact as normally closed. A contact normal state and the process valve normal state are separate descriptions. State the reference condition used to describe the contact as normally closed. A contact normal state and the process valve normal state are separate descriptions. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

- Normally open / normally closed
- The contact state in the normal condition defined for the drawing.
- Coil
- A wound conductor that can produce a magnetic field when energised.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.
