Rockwell Automation 1503 IntelliVAC Contactor Control Module - Series C and later - Manual (Page 24)

Installation and Wiring 3-11
1503-UM052D-EN-P – June 2013
The IntelliVAC can be applied with two- or three-wire control circuits.
The control system utilized will determine the configuration of the input
wiring. Consider the following input and output for the type of control
used:
• Terminals 9 and 10 – Close Contactor
• Terminals 15 and 16 – Contactor Status
In either case, the CLOSE input must receive a maintained voltage high
to keep the contactor closed.
Note:
1. When used with electrically held contactors, the IntelliVAC allows
close commands every six seconds. This is to ensure the rated
contactor duty cycle is not exceeded.
2. If IntelliVAC powers up configured for an electrically held contactor,
and the vacuum contactor is detected as being closed, the module will
not respond to a close command until the vacuum contactor auxiliary
contact input is in the correct (closed) state and module power is
removed and re-applied. (See Chapter 5)
3. In general, a Close command should only be applied 4 seconds after
energizing IntelliVAC.

For Emergency Stop applications requiring
removal of power, a contact should be placed in
the “L1” control power rung to the IntelliVAC.
If the TDUV feature is used, the contactor will
not open until the programmed TDUV time
has expired.
