Rockwell Automation 1503VC IntelliVAC Plus Contactor Control Module - Manual (Page 56)

Description of Features 4-29
1503-UM054C-EN-P – June 2013
Microcontroller Malfunction
This is a serious Fault condition and the IntelliVAC Plus will not
respond to other commands. Refer all servicing to a qualified
service personnel or see the trouble shooting section in Chapter 10.
This indicates that the Basic module within the IntelliVAC Plus unit
has a severe fault due to a microcontroller malfunction and the status
of the contactor being controlled is in an Open condition.
The Module status LED is solid red indicating a severe module fault
and the Module status relay is open to prevent externally connected
circuits from functioning.
The Contactor status LED is Red to indicate that the contactor is in
an Open condition and the Contactor status relay is Open to reflect
the status of the contactor thus preventing externally connected
circuits to function.
This condition is valid for both Electrically Held and Mechanically
Latched contactors.
Power Up with Invalid DIP Switch Configuration
This is a Fault condition and the IntelliVAC Plus will not respond to
other commands until this condition is restored to normal. Check the
settings of the DIP switches and make sure that they are set correctly.
This indicates that the Basic module within the IntelliVAC Plus unit
has a fault due to the module powering up with an invalid DIP switch
configuration and the status of the contactor being controlled is in an
Open condition.
The Module status LED is flashing Red followed by a pause, to
indicate a contactor module that has powered up with an invalid DIP
switch configuration and the Module status relay is open to prevent
externally connected circuits from functioning.
The Contactor status LED is off to indicate that the contactor is in an
Open condition and the Contactor status relay is Open to reflect the
status of the contactor thus preventing externally connected circuits
from functioning.
This condition is valid for both Electrically Held and Mechanically
Latched contactors.
