Help me read this solenoid diagram please

  1. Apr 5, 2009 #1
    Can someone help me understand what this solenoid is doing? It's somehow integrated into a switched shutoff system. I'm trying to figure out if I can jump two wires or ultimately add an on-off switch in line somewhere between the switch and this solenoid. Thanks for any help.

    Looks like a 14vdc relay with contact ratings of 30amp for the normally open contacts and 20amp for the normally closed. The NO contact is between 30 and 87. The NC contact is between 30 and 87a.

    Edit:
    On second thought, it's not clear that the coil is rated at 14volts. i.e. the 14VDC might be the contact voltage rateing. Never seen it shown like that before.

    OK Thanks. That's probably all I need to know. I can usually figure out the easy ones, but couldn't quite comprehend this diagram.
