Lockout setting
If unlocking by password fails for a certain number of times, the module will always be locked out for a fixed period of time.
Frequency of lockout, and lockout time cannot be changed.
■Operation overview
While unlocking the password, the module will lockout when incorrect passwords are entered consecutively for several times.
Even if a password is entered, an error response will be shown at constant time intervals. After a certain interval of time has
elapsed, lockout will be cleared and the password can be unlocked.
Since any password unlock operations are not accepted during lockout, password input errors are not counted even if the
password input errors have been made.
The number of password input errors are counted when the power is on. This count is cleared when the module is reset or if
the power is turned OFF  ON.
The lockout intervals which occur at the time of password errors are as follows:
Number of password input error
1st time to 5th time
6th time
7th time
8th time
9th time or later
*1 Once the correct password is entered, the number of password input error will be cleared.
Locked out
Password input error
1st time to 5th time 6th time
During lockout, unlocking the
password is disabled
The password input error will not be counted during lockout. Therefore, the lockout time will not be extended
additionally by one minute even if the 7th input error occurs before one minute has passed since the 6th.
