4-28 Description of Features
1503-UM054C-EN-P – June 2013
Contactor Drop Out During Hold
This is a Warning condition and the status of the contactor coil or
Contactor Auxiliary Input should be checked.
This indicates that the Basic module within the IntelliVAC Plus unit
has a warning due to the contactor dropping out when it should be in
the hold mode after being given a Close or Jog command and the
status of the contactor being controlled is in an Open or Closed
condition (dependant on the status of the contactor).
The Module status LED is flashing Yellow followed by 2
consecutive red flashes followed by a pause, to indicate a contactor
that has dropped out during the hold operation and the Module status
relay is closed to allow externally connected circuits to function.
The Contactor status LED is Yellow or off to indicate that the
contactor is in a Closed or Open condition and the Contactor status
relay is Closed or Open to reflect the status of the contactor thus
allowing or preventing externally connected circuits to function.
This condition is valid for both Electrically Held and Mechanically
Latched contactors.
Long Contactor Drop Out Time
This is a Warning condition and the status of the contactor coil or
Contactor Auxiliary Input should be checked.
This indicates that the Basic module within the IntelliVAC Plus unit
has a warning due to the contactor requiring too long of a drop out
time and the status of the contactor being controlled is in an Open or
Closed condition (dependant on the status of the contactor).
The drop out time would be up to 130mS after the programmed Drop
Out Time set by the DIP switches (see Table 8.B).
The Module status LED is flashing Yellow followed by 3
consecutive red flashes followed by a pause, to indicate a contactor
that has required too long of a time to drop out and the Module status
relay is closed to allow externally connected circuits to function.
The Contactor status LED is Yellow or off to indicate that the
contactor is in a Closed or Open condition and the Contactor status
relay is Closed or Open to reflect the status of the contactor thus
allowing or preventing externally connected circuits to function.
This condition is valid for Electrically Held contactors only.
