Bulletin 1503VC IntelliVAC Control Module and Bulletin 1500/1900
Medium Voltage Controllers and Bulletin 7000 Medium Voltage Drives,
when using an Emergency Stop Function
Ref: CPAG 2007-08-002
Date: August, 2007
Dear Rockwell Automation Customer,
The purpose of this Product Service Advisory is to inform you of a potential issue that may exist with:
•
Bulletin 1503VC-BMCx IntelliVAC control modules (used to control Bulletin 1502 vacuum
contactors), when using an Emergency Stop function
•
Bulletin 1500/1900 medium voltage controllers and Bulletin 7000 medium voltage drives, when
provided with IntelliVAC control and an Emergency Stop function
This Alert explains the potential issue and the steps being taken to rectify the situation. Due to the nature
of the anomaly, it is mandatory that customers be notified immediately and that the Corrective Action is
implemented immediately.

Issue Description -
The Allen-Bradley Bulletin 1503VC IntelliVAC controller is used to control Bulletin 1502 medium
voltage vacuum contactors, which are the primary components within the Bulletin 1500/1900 Centerline
Medium Voltage Motor Controllers and Bulletin 7000 medium voltage drives.
The following potential issue may exist with the IntelliVAC controller supplied with an Emergency
Stop (E-Stop) function:
Rev 12-2005, Page 1 of 6
PRODUCT SERVICE ADVISORY
Issue – IntelliVAC with Emergency Stop (E-Stop) may not de-energize the power to the module to
ensure that the contactor will drop out of the medium voltage circuit.
A small number of IntelliVAC control modules supplied with E-Stop may have been wired in such a
way that, in limited circumstances, when the E-Stop is pressed the power is not cut to the module. The
IntelliVAC control modules are provided with certain Bulletin 1500/1900 medium voltage controllers
and Bulletin 7000 medium voltage drives. For IntelliVAC controllers sold as separate components (i.e.
not sold as part of the identified drives) to OEM customers, there exists the possibility that the
IntelliVAC with E-Stop may also be impacted (if they did not follow recommendations in the product
user manual).
•
•
•
The E-Stop option could have been wired in the Close command logic. If the optocoupler in the
Close command circuit of the IntelliVAC fails (does not change state), it is possible that depressing
the E-Stop may not de-energize the IntelliVAC output to the vacuum contactor.
The medium voltage circuit may not be de-energized when an E-Stop is depressed.
End customers are advised to review their system requirements functions (e.g., NFPA 79, IEC
60204-1 and ISO 13850) and ensure that the equipment Stop and E Stop provided by Rockwell
Automation or an OEM meets their requirements. If it does not, then immediate action is required to
correct the wiring issue.

- Requested Customer Action Each notified customer should take the following actions:
•
Confirm that they have the affected products.
•
Determine how the product is currently wired, and whether the current wiring meets the required
stop or E-Stop functionality. If corrections are required, execute the wiring changes as indicated per
the wiring schematic as provided in this Advisory.
If customers require any further technical assistance, they should contact Rockwell Automation Medium
Voltage Technical Support (519) 740-4790 or their local Rockwell Automation Sales and Support
office.
We appreciate your immediate cooperation in this matter. If you have any questions, please contact us.
