Rockwell Automation 1503VC IntelliVAC Contactor Control Module - Manual (Page 22)

3-10 Installation and Wiring
1503-UM051D-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 a contactor close command is applied and then removed in less
than 500 milliseconds the IntelliVAC may fault. To clear the
fault, module power has to be removed and reapplied.
3. 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 (open) state and
module power is removed and re-applied. (See Chapter 5). This
is true if the power-up safety DIP switch is enabled.
4. In general, a Close command should only be applied 4 seconds
after energizing IntelliVAC.
