12 Invalid Command Types:
1. Close, Jog or Trip commands present during power up sequence
2. Close or Jog command re-applied too quickly (before contactor opening sequence is verified).
Allow at least 60 msec, plus drop out delay time, before re-applying these signals.
NOTE: Contactor will only respond to a close command re-applications after the re-start delay timer has expired.
3. Close and Trip commands present simultaneously (valid with Mechanical Latch contactors only).
IB Faults / Warnings Healthy Module and Contactor OPEN
This is a Normal condition and no additional action is required.
This indicates that the Basic module within the IntelliVAC Plus unit
has no faults or warnings and the status of the contactor being
controlled is in an Open condition.
The Module status LED is Green to indicate a good module and the
Module status relay is closed to allow externally connected circuits
to function.
