4.2.7 Keyboard Password Lock Function
This function is used to lock the keyboard to prevent the keyboard from being operated by
unauthorized personnel or the parameters are set incorrectly. When the password is set, the
user must enter the correct password before setting the parameters, otherwise the user can
only check the parameters.
1) Set initial password for keypad lock
When using this function for the first time, the user sets the value of parameter P3346.F as the
keyboard lock password. The user must remember the password when setting the keyboard
lock password, otherwise the operation panel cannot be unlocked easily.
2) Keyboard lock settings
If the user needs to lock the keyboard after setting the password, the user can press the
MENU/BACK+ ENTER key combination or set the parameter value to 0. If the password has
been set, the user needs to enter the correct password each time the keyboard is locked or
power on again before setting the parameters. If the password is correct, the password can be
modified by entering the new password.
NOTICE
When the user forgets the set keyboard lock password and cannot unlock the
operation panel, please contact the A-TS technology for technical support.
