What Is Bank Selection - OPTEX FA CVS4-*R Series Instruction Manual

8. Bank Selection

[What is bank selection?]

You can configure up to 16 settings for reading characters on the CVS4 and then use this function to select
the settings by applying an external signal.
For example, consider the case in which the product to be manufactured today has an expiration period of
three days but the product manufactured tommorow has an expiration period of seven days. If you save
settings for the three-day expiration period in bank 0 and settings for the seven-day expiration period in bank
1, you can perform smooth changeovers from one product to another because there is no need to
reconfigure the settings on the CVS4 when the length of the expiration period changes.
You can also use CVS4 button operations to perform bank selection (see [Bank] on P.9).

[Selecting the bank input line function with the parameter settings]
You can also use the four bank selection input lines (0 to 3) for other applications such as the trigger input
and teaching input. To use these for a purpose other than bank selection input, set the [Bank] (P.9),
[Synchron] (P.6), [String +] (P.10), and [SyncPuls] (P.10) parameters according to the following table.

Note) If you set [String +] to "SET0," the pink line will become the function for overwriting the numeric values in the character
string with "0." This will make it impossible to select bank numbers 4 to 7 and 12 to 15, which require the pink line.
* It takes approximately 30 ms from the application of the bank selection signal to the actual selection of the bank, but
approximately 100 ms is required from this point to the point where the next image can be captured.
If you use a bank selection line for a different function such as the trigger input, the number of bank channels that
you can select with external signals will become smaller. If you want to use bank selection lines 0 to 3 for
different functions and fully select between all 16 banks, you can use the alternative inputs shown below.
 When you are using only one of the four bank selection lines from 0 to 3 for a different function, you can
use the red/black NG output line as the bank input line with [NG-I/O] (P.10).

Select bank 2 → The NG line (red/black) can be used in place of bank selection line 2 (pink).
The NG line (red/black) can be used in place of bank selection line 3
Select bank 3 →
(purple).
Reference) You can also use the NG output line (red/black) as the [Str+] or [Tch] line with [NG-I/O] (P.10).
Also, if you want to add inputs by using the NG output and not using the OK output, you can
set the OK line (black) to NG output by setting [Out Sel] (P.10) to "Rev."
You can support 17 or more types of printed details by communicating with the PC to read/write settings. In this
situation, purchase the optional PC I/F cable CVS-C2C (sold separately) and download the setup software (free of
charge) from the Optex FA website.

9. Installation and Related Precautions
[Installation angle when using the built-in lighting]
If you install the CVS4 so that it is parallel with the objects, glare will occur due to the specular reflections of
the light from the built-in lighting, which will make it difficult to capture images with good conditions.
To prevent glare caused by specular reflections, install the device at an angle as shown in the following
figures. The angle varies depending on how lustrous the objects are. For basic objects, use an angle of
approximately 20°. For highly lustrous objects, use an angle of 35°.
* You can also install the device at an angle in the opposite direction (in the following figures, the right side would be higher).
For Horizontal models
(CVS4-N23W-R, -N24W-R, -N21W-R, -N20W-R,
-N40W-R, etc.)

[Set the installation angle with [Trapezid]]
range
If you install the device at an angle, characters are deformed into a trapezoid shape when images are
captured, so set the installation angle with [Trapezid] on P.6.

* If glare occurs no matter how you adjust the installation angle, an external lighting device is required.
Contact Optex FA, and we will provide you with a proposal for the optimum lighting device to match your application.
* If other lighting (such as fluorescent lights) causes glare, implement measures such as installing shading plates.
