An input or output must be assigned to its corresponding point in the control program. This is typically done when
the control program is created, but you can adjust the settings at the time of installation in the i-Vu® interface.
1
In the i-Vu® navigation
tree, select the equipment controlled by the TV-VAVB3-E2.
2
On the
Properties
page, select the
I/O Points
tab.
3
In each point's
Num
field, type the number of the controller's corresponding input or output. For example, if
you use
BO-01
on the TV-VAVB3-E2 for the point
Heat Stage 1
, type
1
in the
Num
field for
Heat Stage 1
.
NOTES

Exp
(expander number) is
00
for the inputs and outputs located on the TV-VAVB3-E2.
•
Do not assign the same output number to more than one point.

Enter the appropriate values for each input and output in the remaining columns. See
Input values
,

To verify each input's operation, force each sensor to a known value, then compare it to the
Value
shown on
the
Properties
page on the
I/O Points
tab.

To verify each output's operation, lock each output to a known condition on the
I/O Points
tab, then verify
that the equipment operates correctly.
