Before you install the CVIM2 system at its factory–floor site, you may find it
useful to connect the basic system components temporarily on a workbench
or table top.
If, however, you intend first to install the CVIM2 system at its factory–floor
site, refer to the following Allen–Bradley publications for site installation
information.
•
Pyramid Integrator Installation Manual, Publication No. 5000–6.2.10.
Chapter 4, Grounding the Components, is of particular importance.
•
Grounding and Wiring Guidelines, Publication No. 1777–4.1.
•
Solid–state Control Safety Guidelines, Publication No. SGI–1.1.
After completing the site installation, return to this section.
Installing the CVIM2 Module
The CVIM2 module uses a DC–to–DC converter to supply power to the
cameras. The converter gets its DC voltage from either the chassis power
supply (+12VDC and –12VDC) or from an external DC power supply
(+24VDC).
When using a 2801–NX3 or –NX4 chassis, here are the situations in which
you must use an external DC power supply:
•
More than three cameras are connected to a single CVIM2 module.
•
Two or more CVIM2 modules are installed in a single chassis, and more
than three total cameras are connected to the modules.
•
Any of cameras #4, #5, or #6 are to be used, regardless of the total
number of cameras used or the number of CVIM2 modules installed.
When using a 2801–AM2 vision chassis, an external DC power supply is not
needed; however the CVIM2 module must have the DC voltage selection
switch set to the 24V position. (The integrated power supply for the
2801–AM2 chassis provides both 12VDC and 24VDC. See Publication No.
2801–2.7, page 9, for more information about the 2801–AM2 vision chassis.)
Use the following steps to set the DC voltage selection switch on the CVIM2
module:
1. Locate the DC voltage selection switch on the back of the CVIM2
module. Refer to Figure 1.1 (page 1–3).
2. Set the switch as shown in Figure 1.1 (the 12V setting) for applications
using three or fewer cameras.
3. Set the switch to the 24V position for applications using more than three
cameras, or using any of cameras #4, #5, or #6.
