IBX-Under voltage with close command present
This is a warning bit which will be set when the control voltage has
dropped below nominal levels, but is either being held up
temporarily using the time delay under voltage feature, or is not
sufficiently low to cause the contactor to drop out.
Network Boolean Inputs
Net In 1-10
These are bits which are can be written to via Device-Net and the
input table of the IntelliVAC Plus. The function of these bits is to
allow the user to influence the behavior of the module via external
inputs from a PLC or other network device.
Dedicated Network command bits
Net In 11/Net Start
The “Net Start” bit behaves differently dependent on the logical
mask which is selected. If logical mask 1 is selected the status of
this bit is directly tied to the IB1 output A (close coil) output. The
contactor will close when this bit is set, and remain closed as long as
the bit remains set. The contactor will open with the bit is reset.
For further information, refer to Logical Masks.
Net In 12/Net Stop
The “Net Stop” bit also behaves differently dependent on the
selected logical mask. This bit is only functional when the logical
mask 1 is selected and a mechanically latched contactor is connected
to the IntelliVAC Base. In this circumstance the “Net Stop” bit is
directly tied to the IB1 Output B (open coil). Energizing this bit will
result in the opening of the mechanically latched contactor.
Net In 13/Net FWD, Net In 14/Net Rev, Net In 15/Net Jog
These bits are network inputs which have been given descriptive
names for the purpose of helping the user identify their function in
the control logic. These bits behave similar to the generic Net In 1-10
bits.
