Error message
Remedy
No value set. Please set value.
A value must be set for this item. Please set up value.
Error of the expression.
Do the following errors exist in settings for an expression set up?
  • Different number of open/close parentheses
  • TJG/unit/value/function/operator/comma is lined next to each other.
  • Operator is set at beginning or end of expression
  • The number of function operands is insufficient or there are more than is needed

"Processing Item List Manual", "Setting (Calculation)"
The problem occurred in the camera connection.
Error mark
Is the camera cable connected to the controller?
Is camera cable disconnected?
Do [Select camera] of [Camera Image Input] and [Camera Switching] have any errors?
Please check the contents of [Camera setting], then switch off and restart.
Setting Conditions for Camera Use
Failed to start the window. Memory is insufficient.
Because memory available for use was insufficient, memory needed to open the window could not be secured. Check the flow by adjusting the measurement region of each processing unit and the sizes of the registered models.
  • [Shape search]
    If shape search+ setup window is opened while the RAMDisk memory is insufficient for image logging, etc. on the RAMDisk, a warning message is displayed. In the case that an image logging file is stored in a RAMDisk, please move the content on the RAMDisk to a USBDisk to open up memory and reopen the set up window.
Warning range shall be set within the range from judgement lower to upper limit.
Please redefine the upper and lower warning range limits such that they are within the range between the lower and upper evaluation limits.
"Processing Item List Manual", "Judgement conditions (Trend Monitor)"
The "Search" measurement result may be "NG (Insufficient memory)" with the current setting.
Insufficient memory may occur during measurement. Reset the model parameters.
The problem occurred in the system.
Error mark
Controller failure. Please contact one of our branches or regional offices.
The problem occurred in system date. The system battery is insufficient.
Error mark
Low battery (for the backup of date and time data) level. The batteries need to be replaced. Please return old batteries to one of our branches or regional offices.
Failed to switch scene
Is a USBDisk set to the controller?
A USBDisk is needed to read scenes after scene group 1.
Failed to switch scene group or save scene group on switch.
The cause of the failure to switch or to save when switching may be that the USBDisk was removed from the controller. Set a USBDisk to the controller and try again.
Failed to clear scene group.
Confirm that a USBDisk is set to the controller and try again.
Failed to load scene group.
Data is corrupted, or memory is insufficient.
Scene group data starts with initialized status.
The following causes are suspected:
  • The power may have been cut off during the last data save.
  • Because the operation mode was switched, the required memory size may have increased and memory became insufficient.
Cannot read selected file. Confirm selected file once again.
Check the following points.
  • Have you removed the USBDisk from the controller after selecting files on the USBDisk?
  • Have you deleted the selected file? (Such as the case when you selected a file on the RAMDisk and the file was deleted via FTP.)
In addition, the selected file may be corrupt.
The communication time-out is occurred.
Error mark
Switch off controller, verify the following contents and then restart.
  • Is cable connected correctly?
  • Does it comply with communication specifications of external devices?
  • Are external devices functioning normally?
If error is not resolved after confirmation, the controller may be damaged. Please discuss this with one of our branches or regional offices.
Failed to transfer data. The free capacity of RAMDisk may insufficient
Increase the free capacity of RAMDisk and then perform this operation again.
Clean up the content of RAMDisk to increase free space. If this error occurs even though enough free space is available, scene group data may be too large. Review the inspection flow.
Error in input range. Please input using the correct range.
Please verify range for setting and set up again.
File name contains invalid character.
Please confirm that characters such as ¥ / , : ; * ? " < > |& . SPC (space) are not included in the file name.
Failed to save file. Please check.
Check the following points.
  • Is the memory of the save destination sufficient?
  • For cases where the save destination is the folder in the USBDisk, is the USBDisk connected to the controller? Or, the controller may not have detected the USBDisk.
Fan/voltage error.
Error mark
Switch off controller, and verify if fan is affected. If error message is still shown after restart, the controller may be damaged. Please contact one of our branches or regional offices.
A camera outside the guarantee is connected.
A camera outside the guarantee is connected to the controller currently being used.
Destination folder is not found. Please check.
Check the following points.
  • Have you deleted the destination folder?
  • For cases where he save destination is the folder in the USBDisk, is the USBDisk connected to the controller? Or, has the USBDisk been detected?
Cannot perform model registration.
Search, classification and flexible search
Please register higher-contrast images as models.
Fine matching
For the fine matching, the 2 pixels at the edge of the image cannot be registered as the model.
Available memory is insufficient.
It may cause insufficient memory depending on the setting.
Available application memory is low.
Memory may become insufficient during operation or an error may occur when the operation mode is switched.
Review the inspection flow and reduce the memory consumption.
The free capacity of RAMDisk is insufficient.
If nothing is done, measurement cannot be performed correctly.
Increase free capacity in RAMDisk.
Clean up the content of RAMDisk to increase free space. If this error occurs even though enough free space is available, scene group data may be too large. Review the inspection flow.
Region size exceeds. Please narrow region.
There are restrictions as to what can be set up based on the camera and processing items being used. Please adjust the region size so that the region is not too large.

Logging error
Image logging failed due to insufficient memory at the save destination. The error message disappears after 10 s. Please delete unneeded files in the save destination or prepare a new USBDisk.
