■ System settings
13. System settings
On the touch panel VT3 system settings screen, you can change the password and set whether or not a sound is emitted
when buttons are touched.
In addition, the system settings screen can be used to monitor the device, by checking the total number of screw tightening
OK judgments.
■ Displaying the system settings screen
To display the system settings screen on the touch panel, first place a finger on the screen where there are no other buttons
for at least 3 seconds, then remove your finger for less than 1 second and touch the top right edge of the touch panel screen.
* For more information, refer to Chapter 9 "Special operations screen" in the "VT3_Hardware.pdf".
■ Checking the screw tightening OK judgment count
You can check the total number of screw tightening OK judgments by viewing the MW07FE and MW07FF built-in touch panel
devices in [デバイスモニタ] (Device monitor) on the system settings screen.
MW07FE: The count increases by 1 for each 10,000 OK judgments. (Unit: 10,000 times)
MW07FF: The count increases by 1 for each OK judgment, and the count is reset to 0 when the count reaches 10,000. (Unit:
1 time)
* For more information, refer to Chapter 5 "System modes" in the "VT3_Hardware.pdf".
Note: When TP project data is transferred, all device values are reset (judgment counts are set to 0).

The buttons do not respond unless they are touched for at least 0.5 second.

When these buttons are pressed, other buttons do not respond for 0.5 second.

■ Holding time
15. Holding time
■ Holding time setting
The holding time setting range is from a minimum of 50 msec to a maximum of 500 msec.
Each screw tightening judgment takes several msec, so when the number of judgments is increased, the actual torque
holding time may become longer than the setting, depending on the holding time value that is specified. When increasing
the number of judgments, it is also necessary to specify a longer holding time.
When using chattering judgment for temporary tightening, a higher temporary tightening speed results in a longer torque
holding time.
When using chattering judgment for temporary tightening, a smaller difference between the temporary tightening torque
and full tightening torque results in a longer torque holding time.
